Director's Report

The year 1996-97 was the last year of the VIII Plan. In the past, the start of plan periods used to be times when usually (though not always) old projects were retitled, milestones, SWOT analysis and other project monitoring tools were incorporated, and proposals for large grants were forcefully presented. We took a different tack this year - by having "open week" for IX Plan projects and succeeding in forging some multidisciplinary projects. This exercise, and other associated "restructuring" was no whim. The recently enunciated Vision 2001 by Dr. Mashelkar with its various milestones, could only be realised by a fresh look at ourselves and the way we did research. It was to a degree unsettling as well. In this Director's report I will avoid restating the "highlights" of the year, but will dwell instead on interpreting important events which are factually reported in fine print in the pages inside. An analysis of our publications showed that while the absolute numbers were going down, the quality of the average paper was getting increasingly better. In order to capitalise on this improving trend, the importance of process studies involving multiple disciplines was an obvious next step. The new titles and objectives consequent to "Project Open Week" are written up and we now need only to follow the spirit of the exercise. I am sure we will. Understanding processes, the focus of oceanography today, is equally important in management - either in project team building or in routine administration. The idea has germinated in a few key areas it will I am sure be obvious for all others soon. Our IX Plan exercise and the ensuing projects reflect this focus. The emergence of the coastal zone as critical to our future human settlement patterns and industrialisation, was a boon to our industrial rupee earnings. It also highlighted the larger roles our national laboratory has to play in providing advisories to concerned ministries, modelling and satellite imageries in predictive and monitoring situations, and the importance of proactive research in devising mitigation techniques to the inevitable onslaught of industrialisation. Our IX Plan projects incorporate these new roles for us as a national institute. Our first dollar earnings from the Indian Oil Corporation (IOC) for environmental services emphasised the wider economic forces at play and the fine job the institute did in this project was an encouraging indicator that marketing such services further afield may prove profitable. The "welcome mat" policy in hosting international meetings, workshops, seminars and symposia gave us exposure to the many facets of oceanography in other parts of the globe, was a reassuring indicator not only of the ease with which oceanographers are able to communicate and forge international programmes, but also that our own were held at some level of esteem in the community. We need now to practise more vigorously all the multi-disciplinary approaches that we know are being woven into oceanographic programmes abroad.

The valiant, almost missionary zeal, with which a two member group is working to get the institute to adopt quality methods, has the hallmark of the beginning of a cultural change. Their success is critical to our survival in the competitive days ahead, and I am sure that we will begin to roll before they run out of enthusiasm. A sobering thought was our response to Dr. Mashelkar's New Ideas Fund encouraging new, innovative even crazy ideas. Our response could have been better especially since we have a funding crunch and need external funding. We have expressed some bold important initiatives for the Year of the Ocean -1998. It is important to succeed in this venture, because of the multiple benefits that we will reap - nationally, regionally and internationally. The year gone by has been internally stressful as it has challenged many concepts of projects, leaders, hierarchy and empowerment of the working level scientist. I am sure however that we will approach the IX Plan with that resilience for which our scientists are noted, by asking "So what's new?"

· Studies on the mechanisms of N2O production in the upwelling zones precludes nitrification as the major process responsible for N2O production. High concentration of N2O and partial pressure of CO2 (upto 62.5 nM and 700 atm respectively) were off SW Indian coast during summer monsoon. These are the highest recorded for any oceanic surface waters. This reinforces the view that the coastal eastern boundary upwelling serve as significant source of greenhouse gases, particularly N2O. Under JGOFS, we observed higher concentrations of Transparent Exopolymer Particles (TEPs) in areas of upwelling in the Arabian Sea than in the Bay of Bengal. Despite the negative relation between TEPs and nitrate deficit, an average TEP concentration of ~ 10 mg I-1 in the Arabian Sea oxygen minimum zone indicates that TEPs provide more than enough organic carbon to sustain bacterial activities in the denitrifying layer. Close grid bathymetric surveys and analysis of nodules carried out under Indian Deepsea Experiment (INDEX) to augment data on likely input due to mining in the Central Indian Basin led to the identification of test and references areas.

Coastal Environment · Continuous observations over 15 months in the nearshore waters off Mumbai showed the peak zooplankton production after the monsoons and high phytoplankton production during the monsoon. Omnivores dominated the zooplankton community showing a partial influence by high fluxes of anthropogenic pollutants from the interior of the creek system.


Abnormal variations in a CTD profile in the Andaman Sea were observed during Cruise SK118. The temperature fell by 4°C while salinity decreased by 35 psu possibly due to tidal solition. Based on the study of a 170 cm long shallow water sediment core (from 22 m), the paleomonsoonal history of the last 2500 years has been reconstructed. Increased precipitation is found to be around 1705 AD and 300 BC and dry climatic conditions around 1565, 1355,1075 & 305 AD.



Underwater explorations off Poompuhar revealed heavily eroded irregular stone blocks at depths of 5-15 m. Airlift · High-resolution shallow seismic operations indicated presence of more reflection data from the continental such blocks in deeper sediments. shelf sediments off western India from 10°-22°N revealed anomalous seismic signatures of acoustic maskings of Engineering & Technology methane rich horizons. Potential subsurface methane estimates in this · Directional wave measurements made gas charged area are of the order in 15 m water depth off Nagapattinam of 2.6 Tg. during the monsoon and fair weather seasons indicated that the spreading parameter could be estimated from the significant wave height and period corresponding to maximum spectral energy without relating to wind conditions. · Knowhow to prepare liquid biofertilizer from seaweeds was transferred to M/s Pralsher Bio-Products Ltd., Curchorem, Goa. Application of this fertilizer increases the yield of horticultural and agricultural plants besides enhancing overall growth and disease resistance. · Evidences of recent volcanohydrothermal activity were recorded in the Central Indian Basin (CIB) previously considered to be inactive. The ferromanganese crust dredged from the summit of the Afanasiy-Nikitin seamount in the North Central Indian Ocean provided evidence that the area was exposed to the subaerial conditions during the Oligocene (~30 Ma) global sealevel drop. Continued studies on neotectonic activity over southern part of ECMI with high resolution sparker data along two E-W tending lineaments off Madras and Nagapattanam provided evidence of recent tectonic activity. Opposing trends were observed in the isotopic composition of 15N and 18O of N2O in upwelled waters with modest departures from the tropospheric values, these indicate that the oceanatmosphere exchange cannot counter inputs of heavier isotopes associated with the stratospheric back flux, calling for additional sources and/or sinks of N2O in the atmosphere.






Offshore Processes · Analysis of XBT data from the tropical Indian Ocean revealed the presence of a narrow equatorial flow between 2°N and 2°S with changing direction at semi-annual cycle. Analysis of 21 years data on SST anomalies in the region 0-5°N and 8085°E (acquired from UK Meteorological Office) showed that the Indian monsoon shows a positive relationship with the SST anomalies of October and November of the previous year




Contract Services

The favourable industrial and investment climate in the country catalysed the start of many green field industries in the chemical, petroleum and power sectors. The Institute provided services in the form of consultancies for pre-feasibility studies and in the form of contracted data collection and analyses for full marine environmental impact assessment reports. The earnings accruing from these services continued to show an increasing trend and the commercial rupees earned crossed Rs. 11 crores a 22% increase over the 1995-96 figures. Industrial activity in the Gulf of Kachchh continued increasing and we undertook 5 projects there, some in environmentally sensitive ecosystems, of corals and mangroves. The cumulative data sets from different surveys in this area should allow us in the near future to compute the additive effects from contiguously situated industries and make suggestions for effective monitoring and mitigation measures.

Two projects, of possible future importance to the Institute were started this year: 1. The India Oil Corporation proposed joint venture port with the Kuwait Oil Corporation at Paradip in Orissa brought us our first foreign exchange earnings. This could become an important trend considering the large number of joint ventures power projects expected to be set up in the next few years.

2. The Gas Authority of India interest in the gas hydrates potential in offshore waters fitted us admirably as it utilised our core competancies in geophysical research in a proactive mode. With increasing pressures to remain commercially competitive, this project was a showcase of collaboration between a research lab and industry. These and similar projects are what we see as fore-runners of the next era of environmental impact assessment programmes.

Environmental Impact Assessment

Shallow water mining The possible environmental impact of shallow water mining of placer deposits off Chavara (Kerala) was studied. The average current, in general, was greater in April than in other months. In all seasons the surface current speed varied between 1 and 49 cm/s and the bottom current between 1 and 35 cm/s. The tide progresses along the coast from north to south in this area. The direction and speed of the residual currents varied with season, depth and location. In general, the residual current direction at the bottom was towards southsoutheast during November, January and April. But during April-May it was towards south at all stations at the surface as well as bottom. Industrial effluents In similar studies to assess the impact due to effluent discharge from a chemical industry and jetty construction in two locations in the state of Gujarat, sampling was done at Kharach and Positra. The baseline data was collected on water quality parameters, temperature, salinity, dissolved oxygen and trace metals. In addition, sediment and fish samples were also collected for rnetal content analysis. In our first analyses of 22 samples from 11 stations we observed concentration of zinc 2.2 - 5.0 g/g and cadmium 0.070.06 g/g In another such survey in Pulicat backwaters and Ennur estuary we noticed high values for phosphate and ammonia during low tide. The suspended load was high in Pulicat backwaters. In general, the southern arm of the estuary appeared polluted due to the discharge of effluents from industries.

This is Among the zooplankton species, confirmed from the observed copepods dominated and the values of oxygen and nutrients density of benthic organisms which indicate that the presence were highest at Calicut and of nitrite associated with low lowest at Kasargod. The heterotrophic bacterial population showed a high incidence in sediments, indicative of the nutritional status of the ecosystem. Among the indicator bacteria group only coliforms occurred regularly suggesting the faecal contamination of the area. West coast Mumbai waters The nearshore waters sustain a rich and diverse zooplankton fauna. Continuous observations for a period of 15 months indicated peak production of zooplankton during the postmonsoon period and high production of phytoplankton during the monsoon period

average cell count (28 x 105 r -1). Of the forty two species, Acartia spinicauda dominated the copepod community. Four species of chaetognaths were found in the area with predominance of Sagitta bedoti. Among the penaeid larvae Metapenaeus affinis was the most common species. Population of omnivores dominated the zooplankton community. This appears to be partially influenced by the high fluxes of anthropogenic pollutants reaching the coastal waters from the interior creek system. Metals in zooplankton Among different metals studied in the zooplankton community, Cu and Zn contributed 60-90% of the total elements accumulated, in general, concentration of Zn was higher than Cu in different groups, with levels of Zn in polluted locations being twice higher than the outer zone. The maximum concentrations of metals was observed in gelatinous organisms which included a variety of carnivores. Metal concentration in copepods was lower than carnivores, with the lowest concentrations of metals in decapods probably because of the effective elimination of a part of the concentrated metal

through periodic moulting. The levels of concentration of metals in crabs and shrimps in this area was high, but within the prescribed limits for consumption. East Coast Gautami-Godavari Hydrobiological studies in the Gautami - Godavari estuarine system showed that 20% of inorganic phosphate and total phosphorus was added to the estuary during the pre- and postmonsoon seasons. However, during postmonsoon period total nitrogen showed a near conservative distribution while geochemical processes removed 13% of nitrate. During the postmonsoon period, phytoplankton counts were higher in the estuarine region than in the coastal regions, whereas a reverse trend was observed in the premonsoon period. Based on the mixing characteristics and flow pattern, the estuary behaves as (i) well stratified during NE monsoon, (ii) moderately stratified in postmonsoon and (iii) partially mixed in premonsoon seasons.

Coastal and Estuarine Dynamics

Modelling for pipeline design Time series measurements of currents, tides and bottom temperature were carried out off Sikka and off Mundra in the Gulf of Kutch for 35 days from JuneJuly 1996 using both DCM-12 and RCM-4 current meters. There was no noticeable vertical shear except during the time of strong winds when the currents at the uppermost level were higher.

Using a software package TIDAL the tidal circulation in the Gulf of Kutch was simulated. An open boundary was selected along the Okha point. The model output of current components and tidal height were compared with the currents and water elevation measured using DCM-12 current meter off Sikka and Mundra. The model results showed good agreement with the measured values.

Biodiversity and Biomedical Potential

Biodiversity Planktonic foraminifera off the Kerala coast Twenty-eight species of planktonic foraminifera were recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala coast. The mean abundance of total foraminiferal specimens of all stations in each traverse showed an increase from south to north. Two distinct foraminiferal assemblages were noted - (i) a summer tropical one typified by species such as Globigerinella aequilateralis, Globigerinoides conglobatus, G. ruber and G. sacculifer, (ii) a summer tropical upwelling assemblage formed by species, viz.Globigerina bulloides and Neogloboquadrina dutertrei. The spinose species of the genus - Globigerinoides were the most abundant. The fauna in general is similar to that of the western Sargasso Sea and western north Atlantic in that it is characterised by summer species such as G. ruber, G. sacculifer, G. conglobatus, G. aequilateralis, O. universe and H. pelagica, but differs in having G. sacculifer as the most abundant species in lieu of G. ruber.

diversity of the population, Baypore estuary ranked first; Blackfordia virginica, Eutima commensalis, Eirene cylonensis, Phialidium hemisphacricum and P. brunescens were the commonly occuring species. Ostronmovia inkermanica was recorded from Mumbai estuarine system. Salinity was found to be the limiting factor for the growth and activity of hydromedusae. Biomedical potential Investigations on this national project for development of new and safe drugs from the marine environment was continued. Major emphasis was laid on the isolation of active constituents from a mangrove (NIO-450). Fifteen new extracts and earlier promising fractions were sent to participating laboratories for testing for specific activities. Gorgonian NIO-484 Tricyclic sesquiterpenoid, subergorgic acid, having potent cardiotoxicity (Fenical, et al., 1985) and its hydroxy, acetoxy analogs along with a novel polyhydroxy sterol were isolated. Structural investigation of the sterol is in progress. Soft coral NIO-488

Marine organisms screened for bioactivity.

Species diversity in hydromedusae A comparative study was made of species diversity, abundance and distribution of hydromedusae from different estuarine systems of the west coast of India. Maximum species diversity (345 species) was observed from Mumbai harbour and Thane Bassein estuarine complex. Cochin backwaters had 22 species and Baypore estuary had only 6 species. In

Chemical studies of methylene chloride fraction of this soft coral yielded several sterols in addition to fatty acids and their methyl esters reported earlier. The sterols included 24 methyl and ethyl cholesterol, 24 methylene cholesterol, 24 methylene 8 dehydro cholesterol, 24 methylene 5, 8 diene3B-01,24 methylene-5, 22-diene3B, 7B-ol. All these compounds were characterised using spectroscopic techniques.


Gorgonian NIO-496 Several monohydroxy sterols and fatty acids were isolated from petroleum ether fraction whereas CHCI 3 fraction yielded caffeine, its 2-OMe analog. Nmethyl pyrazole carboxylic acid and 1, 3, 5, 6-tetrahydroxy cholestane. Caffeine had mild antifouling properties, whereas its O-Me analog was devoid of this activity. Mangrove NIO-497 The crude methanolic extract of this mangrove exhibited antibacterial activity located in butanol fraction. Two compounds K006 and K007 (flavonoids) isolated from the active fraction, have shown anti-bacterial activity at 30 mg/ml concentration against six bacteria.

Red alga NIO-499 Detailed chemical investigation of this alga led to the isolation of 24-nor-cholest 5, 22-diene 3B-ol; 24-methylene cholesterol, 24ethyl 5, 22, diene-3B-ol. Further fractions on repeated column chromatography gave a colourless crystalline solid which was tentatively characterised as Nsubstituted pyrazine derivative. Steroids from marine sponge Two sponges studied contained C27-29 mono and diunsaturated sterols. One of them in addition contained cholest-4-ene-3-one. Butyl alcohol, its higher homologue and a heteroaromatic acid, 4 methyl-pyrazole 3(5) carboxylic acid have been identified. The nucleoside from one species was found antiviral and identified as spongoadenosin or Ara-A.

Marine Archaeology

Onshore explorations of the Tamilnadu coast Onshore archaeological explorations were carried out at Ramnathpuram, Rameswaram and Nagarcoil coast in Tamilnadu for ports and ancient settlements. A mooring stone was noted at Algankulam and an ancient port site belonging to Sangam period situated about 3 km from the seashore near Ramnathpuram. Another important site at Aryangundur is situated in Rameswaram island. A high cliff section facing sea was noticed and a lot of pottery was collected. More than two metre deposit of human settlement with remains of shell works suggests a port that was in service for a long period. The discovery of Chinese pottery suggest a habitation of 1Oth-11th century and trade contact with east.

Explorations at Puttan Thurai and Manakudi yielded evidences of habitation from the Medieval period. Evidence of an ancient temple was also traced at Puttan Thurai. Offshore Explorations in Poompuhar waters Underwater explorations off Poompuhar revealed the presence of a few stone blocks in various water depths. Airlift operations revealed the presence of several stone blocks in deeper sediments. Further exploration of a shipwreck off Poompuhar showed a wooden hulled ship with surface badly damaged by borers. A large number of lead ingots found there indicate that the ship of Danish nationality possibly belonged to another East India Company.

Design Methodology for Coastal Structures

Feasibility studies Pre-feasibility study for construction of a jetty at Ambolgarh, based on the available data on wave climate, tides, longshore currents, sediment transport and a site visit, was carried out. Similar studies were also done for dredging of river mouths at Chapora, Sal, Saleri, Talpona and Galjibag along the Goa coast. Along the east coast, studies on the effects of dredging to improve the salinity of the Chilka lake and better water exchange with the sea was carried out. Locations for sea water intake and warm water discharge for the proposed power project near Dabhol port (Maharashtra) were identified. Directional wave modelling Directional wave measurement carried out at 15 m water depth off Nagapattinam indicated that during the observation period the highest significant wave height was about 2 m and the highest maximum wave height observed was about 3.8 m. The zero crossing wave period varied between 3 and 9 s, and wave direction varied between 100° and 170° during SW monsoon and between 60° and 120° during fair weather period.

The study also showed that the spreading parameter can be estimated from the significant wave height and wave period corresponding to maximum spectral energy without relating to wind conditions. The unidirectional spectra can be modelled using the Scott spectra. Wave directional spectrum Wave direction has for the first time been consistently, accurately and unambiguously evaluated from array measurements using phase/ time/path difference methods of Esteva (1976,1977) in case of polygonal arrays and Borgman (1974) in case of linear arrays. We have used time series measurements of water surface elevation at a 15-gauge polygonal array, in approximately 8 m water depth, operational at the CERC's Field Research Facility (FRF) at Duck, North Carolina, USA. Two modifications were made in the methodology. In one, we use the true phase instead of the apparent phase, and the estimates of wave direction are registered only if the relevant gauges are coherent at 0.01 significance level. PTPD methods assume that in a spectral frequency band, the waves approach from a single

direction - and are simple, expedient and provide redundant estimates of wave direction. Our estimates of wave direction are in agreement with the results obtained by the FRF using the sophisticated Interative Maximum Likelihood Estimation method, which assumes that at a frequency band, waves can approach from all directions. (Fernandes et al., 1996. Proc. Intl. Conf. in Ocean Engg., IIT Madras, 243-248). Optimal parametric modelling The spectral analysis of measured short waves can be expressed by parametric models namely autoregressive or moving average algorithms which are polynomial functions. Further reduced-order,

autoregressive, moving average spectral estimations are successfully applied to time series waves with different sampling rates. This study emphasised the importance of selecting a suitable sampling interval for better estimates of parametric modelling and also for better statistical representation. Geotechnical studies of marine sediments Undisturbed seabed sediments were collected off Chavara, off Tuticorin, from 35 locations off Ennore, and from several beaches of Goa to study geotechnical properties in connection with dredging of placer deposits, laying of submarine pipeline and beach protection purposes.


Autonomous Meteorological Data Acquisition System for coastal research vessel Two autonomous Meteorological Data Acquisition Systems for the coastal research vessel of the Department of Ocean Development have been designed and installed on RV Sagar Paschimi and RV Sagar Purvi. The system is based on Motorola 68332 data logger to acquire surface meteorological parameters such as winds, air temperature, barometric pressure, solar radiation and relative humidity. A personal computer is used for on-line display and storage of the data. The computer is also interfaced to a shipboard GPS receiver for position tagging. Ship speed and heading data from the GPS receiver is then used to estimate true winds. Data acquisition software is implemented to run in a windows environment to provide front-end graphical interface. The system supports networking capabilities that can monitor data from other personal computers in the network. Remotely Operable Sea Skimmer (ROSS) ROSS is an autonomous unmanned vehicle designed for use in bathymetric surveys in coastal and estuarine environments to complement manned survey vessels in hazardous environments. Two distinct proofs of concept versions of the ROSS hull have been conceived and implemented in the field using a theter. In ROSS version 1, developed at the IIT Chennai, the vehicle is a standard catamaran hull fitted with stabilising skegs. In a second patented version developed at NIO the hull is made from a free flooding HDPE tube enclosing 3 buoyant sealed bins containing

batteries and electronics. A detachable aluminium frame bolted to a welded rib on the outer hull carries two brushless DC thrusters. Both versions are equipped with a GPS (Global Positioning System) to measure position on the sea surface. Additional sensors include a low cost echosounder, digital compass, temperature and a UHF radio modem. ROSS is currently being developed to receive commands over the UHF link and io send acquired data to the user controlling it. The project is an ongoing collaborative venture involving NIOT, Chennai, IIT, Chennai and NIO, Goa with funding from the Department of Ocean Development, New Delhi.

PVC protective wells for guided air-acoustic sea level gauges PVC protective wells for airacoustic sea level gauges were fabricated and supplied to Survey of India under the SELMAM project. These wells were installed at the ports of Mormugao, Chennai and Port Blair during April-May, 1996.

ROSS version 2

Installation of the system at Mormugao harbour was undertaken by NIO. Two sources of errors associated with this gauge have been investigated, namely trapping of low density water and temperature gradient in its sounding tube. These effects were investigated by periodic profiling of water density inside and outside of the protective well and air temperature profile external to the sounding tube and within the protective well. It was observed that trapping effect gives rise to overestimation of water level upto 1% of tidal range at Zuari estuary, Goa. The error in sea level measurement due to temperature gradient within the sounding tube of the air acoustic gauge had been found to be maximum (5-6 cm) during summer day times. We have implemented a temperature correction scheme which partially reduces the error from this source. Our studies thus reveal that the so called 'Next Generation Water Level Measurement System (NGWLMS)' does not provide the desired millimeter scale accuracy.

Biofouling & Corrosion

Microfouling Suspended particulate matter (SPM) and the biofilm material on aluminium panels immersed in water were analysed. The diversity of diatom population and that in the fouling film is not reflected evenly indicating that recruitment of diatom cells is not fully controlled by their diversity in the water column. Exopolymers isolated from barnacle shells bearing bacteria and the adult extract were found to promote settlement of cyprids.

Anticorrosion properties of marine sponge In our attempt to explore and develop anticorrosion formulations we made an attempt to study a marine sponge. The aqueous extract of this organism at 1.5 mg/ml concentration was found adequate to produce a passive steel surface. The inhibition mechanism was studied by gravimetric and potentio-dynamic techniques.

Prawn culture A pilot scale prawn hatchery and aquaculture facility with modern amenities has been established, under the Technology Mission Mode Project on "Semi-intensive Prawn Aquaculture" funded by the Department of Biotechnology. The hatchery has an annual production capacity of 2 million post-larvae. The system was also found to be efficient in breeding and culturing giant freshwater prawn Macrobarchium rosenbergii. Techniques for culturing larval stages of Penaeus merguiensis have been developed and perfected. Techniques have also been developed and standardised for mass culturing of phytoplankton species and Artemia nauplii as prawn larval feed. Experiments were conducted on: - Respiratory metabolism in juvenile Penaeus monodon; - Effect of salinity and pH on growth of postlarval Penaeus merguiensis; - Hatching performance of brine shrimp; - Formulation of cost effective prawn postlarval feed -Antagonistic behaviour of phytoplankton. Culture Technique for HorseShoe Crab A field laboratory has been established at Balramgari, Orissa. Three rearing ponds (30 x 6 m) have been constructed for culturing of horse shoe crab under captive conditions. This will ensure the sustainable supply of the raw material for the preparation of a diagnostic reagent (LAL). A new species has also been found along the Paradeep coast.

Biofertilizer Knowhow was developed to prepare seaweed extract as biofertiiizer to be used in agriculture and horticulture. The extract containing hormones, micronutrients and trace metals when sprayed on plants showed cumulative effect such as increase in the rate of seed germination, leaf & fruit sizes, yield and resistance from insect attack. The knowhow has been transferred to M/s Pralsher Bioproducts Ltd., Curchorem, Goa for commercialization. The product is marketed by the firm under brand name PLANTOzyme. Genetic Studies Isozyme analysis conducted on a few specimens of lantern fish (Myctophidae) collected from the Indian Ocean sector of the Antarctic Ocean indicated very high genetic variation in these species. Information on the population genetic structure of these myctophids will be of vital importance for future large scale fishery programmes, as well as for a more general understanding of the Antarctic marine ecosystem. Very clear differentiation between the two species analysed was seen at the LDH and MDH loci, could be used as reliable markers to identify these species. Studies were also undertaken on the genetic divergence and phylogenetic relationships in 3 species of threadfin breams (Nemipteridae) collected from Goa waters. Four isozyme loci were found to be reliable species specific markers.

Physical Processes in the Tropical Indian Ocean

Western Indian Ocean

Current systems and transports The XBT data collected along the Mumbai-Mauritius shipping route during 1992-1996 under the TOGA-I XBT programme were analysed and the seasonal upper layer (0-760 m) thermal structure, heat content and zonal flow patterns were determined. The temperature of the surface homogeneous layer (SHL) increased from 28°C to 30°C from winter to summer while its thickness decreased from 40 to 20 m north of the equator. The slope and spatial changes in the thermocline revealed the presence of seasonally variable zonal current systems: North Equatorial Current (NEC), Indian Monsoon Current (IMC), Wyrtki's Jet, South Equatorial Current (SEC) and South Equatorial Counter Current (SECC). The spreading of thermocline at subsurface depths (~100 m) also revealed the presence of equatorial undercurrent (EUC) during winter (February). The equatorial Wyrtki's Jet was evident during summer (May) and the winter transition

(October). The thermal structure sections further showed the presence of a dome between the SECC and SEC called the "Southern tropical Indian Ocean Thermal Front" (SIOTF) with its axis shifting poleward with depth. This front reached up to the SHL and shifted close to the equator during the SW monsoon. The SIOTF intensified with large lateral gradients during January-February (southern summer). Below 200 m, the temperature of the tropical Indian Ocean appeared to be affected by the location of SIOTF with warmer waters to its north and south. This frontal structure was characterised by lower heat content (in the upper 760 m column) compared to its northern and southern sides and its seasonal variation was related to the seasonal variation of SEC transport. (Sarma et al., 1996. Communicated to Oceanologica Acta). The analysis further revealed the presence of a narrow equatorial flow between 2°N and 2°S persisting for the whole year apart from the other current systems of the tropical Indian Ocean. The equatorial

flow exhibited semi-annual cycle with a mean westward transport of 19 Sv during February-July and a mean eastward transport of 22 Sv during September-February. The transport of IMC showed variations, with higher (14 Sv) values during July between 3° and 5°N. Similarly, NEC also exhibited wide variations in its transport (7 - 34 Sv) during January-March. Off the SW coast of India, the presence of a warm core eddy during February and a cold core eddy during October were noticed. The SEC was found to be a perennial phenomenon in the southern tropical Indian Ocean with seasonal variability in its transport and northern boundary. The SECC is also a yearround feature whose seasonal transports appeared to be related to the equatorial flow (Murty et al., 1996. Communicated to Deep Sea Res.).

Bay of Bengal Circulation Hydrographic data collected from 3 to 10 September, 1996 along two transects, one along 18°N and the other along 90°E, were utilised to examine the thermohaline circulation and chemical properties of the Bay during the withdrawal phase of the SW monsoon. The surface salinity exhibited wide spatial variability with values as low as 25.78 psu at 18°N/87°E and as high as 34.79 psu at 8°N/90°E. Two high salinity cells (S>35.2 psu) were noticed around 100 m depth along the 90°E transect. The wide scatter in T-S values between 100 and 200 m was attributed to the presence of the Arabian Sea High Salinity Watermass (ASHSW). Though the warm and low salinity conditions at the sea surface were conducive for rise in the sea surface topography at 18°N, 87°E, the

dynamic height showed a reduction of 0.2 dyn.m. This fall was attributed to thermocline upwelling noticed at this location. The geostrophic currents showed alternating flows across both the transects. Relatively stronger and mutually opposing currents were noticed around 25 m depth across the 18°N transect with a velocity slightly in excess of 30 cm.s -1. Similar high velocity (>40 cm.s -1) pockets were also noticed to extend up to 30 m depths in the southern region of the 90°E transect. However, the currents below 250 m depth were weak and in general < 5 cm.s -1. The net geostrophic volume transports were found to be of the order of 1.5 Sv towards the north and of 6 Sv towards the west across the 18°N and 90°E transects respectively. The surface circulation patterns were also investigated using the trajectories of drifting buoys deployed in the eastern Indian Ocean around the same observation period. Poleward movement of the drifting buoy with the arrival of the IMC to about 12°N along the eastern rim of the Bay was noticed in early October. The presence of an eddy in the SW Bay and the IMC along its southern periphery was also evident (Sarma et al., 1996. Communicated to Deep Sea Res.).

Arabian Sea Transparent exopolymer particles The biogeochemical significance of Transparent Exopolymer Particles (TEP) in the ocean was studied under the JGOFS programme. Concentrations of TEPs were higher in the Arabian Sea than in the Bay of Bengal. TEP concentrations were higher in the upwelied surface waters of

the Arabian Sea. The availability of nutrients triggered intense biological production leading to enhanced release of extracellular material. Very high concentrations of TEPs were found at ~ 600 m at 18° and ~ 20°N where upwelling occurred. Such concentration gradients were not seen in the Bay where TEPs varied within a narrow range. The TEPs number was less and the sizes were relatively large in the Arabian Sea due to the stickiness. The bacterial numbers were higher in the Bay facilitating particle breakdown and reduction in stickiness thereby increasing TEP numbers. The small percentage of TEPs that were associated with mineral particles in the Arabian Sea could have been due to the lower inputs of terrigenous particles through rivers and atmosphere. This explains the higher sinking fluxes of organic carbon in the Bay than in the Arabian Sea (2.04 - 3.59 and 1.53 -1.80 gC m-2 y-1, respectively) and provides direct evidence for the mineral ballast hypothesis that links the long-term storage of atmospheric carbon dioxide in the ocean to the organicmineral interactions in the water column. Decreased levels of TEPs coincide with higher secondary nitrite and nitrate deficits suggesting the involvement of TEPs in bacterial respiration / production in denitrifying layers. Despite the negative relation between TEPs and nitrate deficits an average TEP concentration of ~10 mg I-1 persisted in the Arabian Sea oxygen minimum zone. This reveals that TEPs provide more than enough organic carbon to sustain bacterial activities in these denitrifying layers. Consequently, this carbon pool of TEPs may account for the hitherto unknown 'carbon substrate' required to meet the bacterial demand in subsurface

layers of the Arabian Sea. (Kumar et al., 1996. Accepted Geophys. Res. Lett). Prediction of monsoon A detailed investigation of the warm pool and SST anomalies (SSTA) in the equatorial Indian and west Pacific Oceans was carried out using 90 years (1906-1995) data on SST anomalies obtained from the U.K. Meteorological Office, Bracknell. Relationships between the SSTA and monsoon rainfall was also examined using 21 years data on SSTA. It was found that the Indian monsoon rainfall was positively correlated (r = 0.75) with SSTA in the region, 0-5°N and 8085°E during October and November months of the previous year. Dual isotopic composition of nitrous oxide In our Indo-US collaborative investigations, measurements of dual isotopic composition of dissolved N2O in oxygendeficient waters of the Arabian Sea show that denitrification leads to mid-depth enrichments of both 15N and 18O in N2O, that are by far the largest reported from any natural environment. However, this layer is effectively isolated from the atmosphere by the overlying layer which is characterized by high concentrations of tighter N2O. We have also acquired the first data set on isotopic composition of N2O from an intense upwelling zone (off the SW coast of India) where some of the highest concentrations of N2O at the sea surface (up to 62.5 nM, 953% saturation) were observed. The N2O-rich upwelled waters are moderately depleted in 15N (by 6), but slightly enriched in 18O (by 3 ) compared to tropospheric N2O. The observed opposing trends in 15N and 18O, and


modest departures from tropospheric isotopic composition, clearly indicate that the ocean-atmosphere exchange cannot counter inputs of heavier isotopes (particularly 18 O) associated with the stratospheric back flux, calling for additional sources and/or sinks of N2O in the atmosphere. Our results also provide important insights into the mechanisms of N2O production. As N2O produced by nitrifying bacteria is highly depleted in 1 5 N, the modest depletion of 15N observed by us even within the most active upwelling zones appears to rule out nitrification as a major process responsible for oceanic N2O production. Within the suboxic zone, the 15N of nitrate is lower than the corresponding value for N2O by 4.6-9.70/oo at depths >= 200 m, and higher by 0.6-3.80/oo at shallower depths, suggesting that the mechanisms of intense N2O accumulation at the upper and lower boundaries of the suboxic layer may be quite different. It is proposed that while denitrification may be the principal mechanism for the production of isotopically-heavy N2O in the deeper layer, isotopically-light N2O in the upper water column may be produced dominantly through nitrification-denitrification coupling involving nitric oxide (NO). Upwelling off the southwest coast of India intensive observations made during the SW monsoon of 1995 revealed intense upwelling off the SW Indian coast causing high nitrate concentrations at the sea surface. While denitrification did not appear to occur in the water column, the ratio between nitrate+nitrite and phosphate exhibited consistent decrease with depth at all shallow stations suggesting a

strong sedimentary sink of nitrate. Concentrations of nitrous oxide (N2O) and partial pressure of carbon dioxide (pCO2) (up to 62.5 nM and 700 atm, respectively) were among the highest recorded in oceanic surface waters supporting the view that the eastern-boundary upwelling zones serve as significant sources of greenhouse gases, particularly N2O. Close coupling between nitrification and denitrification might cause extremely high N2O concentrations (reaching up to 138 nM) in near-bottom waters close to the coast. Andaman Sea Abnormal variations in a CTD profile were noticed in the Andaman Sea during SK118 cruise. The temperature fell by 4°C while the salinity decreased by 0.35 psu at 100 m depth at 10°30'N, 93°15'E within about 2 hrs. Sound velocity also decreased by 10 m.s -1 at this depth. The 24.0 ot isopycnal surface shoaled from 120 m to 90 m. An unexpected minimum in dissolved oxygen (34 mol/l) and a peak in silicate (36 mol/l) were noticed at this location. The above features could be due to a solition or a fast moving coldcore sub surface eddy.

Paleomonsoonal history of the last 2500 years has been reconstructed by studying a 170 cms long shallow water (22 m) sediment core collected near the mouth of the Kali river. River influx intensity was inferred from planktonic forarminiferal and angular asymmetrical morpho-group of benthic foraminiferal abundances. The rate of sedimentation was determined from radio carbon dating. The downcore variation of the above parameters show that the Arabian Sea witnessed increased precipitation around 1705 AD and 300 BC and dry climatic conditions around 1565,1355, 1075 and 305 AD. Interestingly, these periods, coincide with archaeological events and records in ancient scriptures (e.g. Akbarnamah) describing higher rainfall and famine periods. (Nigam and Khare, 1996. An Integrated Approach to Marine Archaeology, 27-30).

Coiling directions in foraminifera and paleoceanography A high-resolution time-series analysis of the coiling patterns of two planktic foraminiferal species, Neogloboquadrina pachyderma and Globigerina bulloides has been carried out at ODP Site 723A, beneath the seasonal upwelling region of the Oman Margin in the Arabian Sea. Results indicate that accumulation rates of the sinistral morphotype of N. pachyderma increased during the period of strong upwelling between 10.5 and 5 ka B.P. The dextral morphotype of N. pachyderma shows greater values during the last glacial period when upwelling was relatively weak. Fluxes of both the sinistral and dextral morphotypes of G. bulloides increased during the interval of stronger upwelling. Greater increase in the flux of the sinistral than of the dextral morphotype of G. bulloides during this interval resulted in higher proportions of the sinistral morphotype in the sediment record. Enhanced flux of the sinistral morphotypes of N. pachyderma and G. bulloides during periods of intensified upwelling suggests that the sinistral morphotypes of both taxa are more productive than the dextral morphotypes in the nutrient-rich upwelling waters. These patterns indicate that surface-water temperature may not be the only factor control-

Paleomonsoons in late Holocene Studies on the variability of the Southwest (SW) monsoon strength using the upwelling indices (fluxes of total planktonic foraminifera and Globigerina bulloides) from the western Arabian Sea reveal that the weakening phase of the SW monsoon started about 5 ka B.P. (ka = 1000 years). The intensity of monsoon returned to glacial strength at 3.5 ka B.P., coinciding with the onset of arid climate elsewhere in the tropics. The onset of the weak phase of the monsoon and arid climate at 3.5 ka appears to be a primary reason for the decline of the Indus Valley Civilization, major changes in

Culture of benthic foraminifera A programme for laboratory culture of benthic foraminifera to study their growth was initiated. These experiment assume importance as the foraminifera-based techniques are increasingly being used to generate the high resolution proxy records for paleoclimatic reconstruction. Among the samples studied from the nearshore regions of Goa the benthic foraminifera Rosalina leei were found abundant and have been used for culturing. Erdschreiber medium was found to be conducive for their growth and chamber formation. Excess food supply showed retarded effect on overall growth rates. (Nigam etal., 1996. J. Paleontol. Soc. India, 41:29-35).

Trace and rare-earth elements in the Arabian Sea sediments beneath and outside OMZ and Paieoceanographic implications CaCO3 organic carbon Corg trace and rare-earth elements (REE) have been determined in surface sediments collected from a transect of the WCMI cutting across the Oxygen Minimum Zone (OMZ). Shale normalized REE patterns, Lan/Ybn ratio and Eu/Eux anomalies indicate that the sediments in the study area are either derived from the adjoining Archaean land masses or from distal Indus source. Sediments from the OMZ record highest uranium contents, indicating that the U may be precipitated as U+4 under the reducing conditions of OMZ.

Sediments deposited beneath the intense OMZ (oxygen <0.2 ml.l-1) and away from the OMZ (oxygen 1-2 ml.l-1) show slightly negative Ce anomalies, though there is no significant difference between the two sets of sediments. The Ce/Ce*shale values are poorly related to U and Corg which is indicative of sub-oxic bottom waters. Normative calculations suggest that two sources, namely, terrestrial and seawater (terrestrial»seawater) contribute to the total Ce anomaly of the sediments. The Ce anomaly values of the calculated seawater derived component are similar to the anomalies reported for the coastal waters and the oxygenated surface waters of the Arabian Sea and do not show any relation to the towered redox state of the overlying water, probably due to the redirection of dissolved Ce into the oxic deeper water. The data on recently deposited sediments from a known oxygen-poor environment suggest that the Ce/Ce*shale in high sedimentation areas of continental margin environments may not be a good paleoredox proxy. U/Th ratios above 1.25 noticed in OMZ are in accordance with the earlier usage of this ratio for identifying reducing environment from ancient sediments. (Nath et al., 1996. Geochim. Cosmochim. Acta., in press).

Aeolian input to the sediments of SW continental margin of India Kaolinite, smectite, illite and chlorite as the major clay minerals and palygorskite and gibbsite in minor quantities have been recorded from the slope of the southwestern continental margin of India. Contribution of kaolinite, smectite and gibbsite is from peninsular India through fluvial


discharge. Since formation of palygorskite regime needs arid, hot climate and saline condition, occurrence of this clay in the sediments suggests aeolian transport from Arabia and Somalia by the Arabian northwesterly winds. (Chauhan, 1996. Curr. Sci., 71: 233-236). Paleoceanographic interpretation from a study on ferromanganese crust A ferromanganese crust dredged from the summit of the Afanasiy-Nikitin seamount in the North Central Indian Ocean (NCIO) had recorded Neogene oceanographic events. The substrate of the crust is composed of fresh water phreatic calcite cement, Terebratulinae casts, rounded ferruginised basalt clasts and weathered coralline algal fragments suggesting an exposure to subaerial conditions during the Oligocene (-30 Ma). The mineralogy, major, trace and REE element geochemistry and co-model age estimates imply three distinct accretionary environments during the crust growth:

(i) a period of contemporary precipitation of Fe-Mn oxide and carbonate fluor apatite (CFA) in intermediate water oxygen minimum zone (OMZ) in the late Miocene, (ii) a pulse of highest CFA precipitation and detrital input in addition to Fe-Mn oxide accretion at the close of Miocene reflect most intense OMZ and erosion of Himalaya and, (iii) an improvement in the oxidizing condition of ambient water due to contraction of the late Miocene OMZ facilitated an accretion of pure Fe-Mn oxide during Pliocene and later. As a consequence of significant deposition of CFA in addition to Fe-Mn oxide during the intensified OMZ, the normally coherent behaviour of trivalent rare earth elements (3+ REE) is not observed in the crust. La, Yb and Lu show a positive association with the CFA phase elements (Ca and P) and Pr, Nd and Sm with the Mn-oxide phase elements (Mn, Co and Ni). This leads to an abnormal, incoherent behaviour of the 3+ REE in multimineral authigenic system. (Banakar, et al., 1996. Mar. Geol., 136: 299-315).

Neotectonic activity over ECMI Magnetic, gravity, bathymetry and high resolution seismic studies of the southern part of ECMI indicated three major lineaments. An E-W lineation off Nagapattanam fits well with a major E-W trend delineated on land as Palghat Tiruchurapalli shear zone which is considered an important tectonic boundry. The

lineation off Pondicherry at 12°15'N correlated with the offshore extension of an onland lineament trending NE-SW between Kambam and Pondicherry with an steep turn near the coast off Pondicherry. Gravity and magnetic data off Chennai showed possible offshore continuation of a transition zone identified over Peninsular India. The offshore fragment of this lineation was


characterised by a free air gravity rise of about 100 mgals, negative magnetic anamoiy of 200 nT and also associated with a steep bathymetry rise of 2.5 km. Magnetic modelling indicated a shallow basement at a depth of about 5 km flanked by deeper source both from north and south. Geomorphic features such as fault valleys, V-cut channels and sediment slumps were inferred from high resolution sparker data along two E-W trending lineaments off Chennai and Nagapattanam which indicate recent tectonic activity in this part of the eastern continental shelf. Inversion of magnetic data along 40 profiles of the eastern margin between Visakhapatnam and Paradip indicates (i) a shallow and highly faulted basement in the innershelf; (ii) a NE-SW ridge trough configuration in the midshelf; (iii) transition from continental to oceanic basement at the foot of the continental slope; (iv) NW-SE basement upward off Bhimunipatnam to Kalingapatnam and (v) N-S basement trend off Chilka lake. Dual channel echosounding surveys carried out in the shelf area between Gopalpur in the north and Pudimadaka in the south revealed relict morphological features like pinnacle reef system both in the innershelf and outershelf regions. Sedimentological studies carried out on five short cores collected from the deformation zone of the Central Indian Basin (CIB) show two distinct sedimentary facies associated with abyssal plain and abyssal hills.

Crustal evolution of the Bay of Bengal Bathymetry, magnetic, gravity and multi-channel seismic reflection data acquired in the Bay of Bengal and in the distal Bengal Fan have thrown more light on break up of India from eastern Gondwanaland and the post-break up events of the northeastern Indian Ocean. The trend of the fracture zones, the location of the major magnetic chron 34, and the Cretaceous Magnetic Quiet Zone suggest that Greater India separated from Antarctica in the early Cretaceous (i.e. polarity chron M0 120 Ma) and drifted northwestward. Negative gravity anomalies are associated with basement rises between the continental margin of India and the Ninetyeast Ridge. Magnetic reversals and northward trend of the 85°E Ridge support a hotspot origin of the ridge and that its emplacement took place probably after the Cretaceous quiet period. Juxtaposition of high-amplitude hyperbolic reflections, down-faulted continental blocks buried under thick sediments, and associated gravity and magnetic anomalies indicate the boundary between continental and oceanic rocks at the foot of continental slope, about 80 km seaward of the present continental shelf edge. Eight seismic sequences, as thick as 8.5 km, overlie the early Cretaceous oceanic basement and include four unconformities (lower Eocene, upper Oligocene, upper Miocene, and upper Pleistocene) which correspond to the major geologic/ tectonic events. Late Cretaceous/early Tertiary feature on the eastern flank of the buried 85°E Ridge is interpreted as a carbonate reef. The steep subduction of older (cold)

Indian plate beneath the Burmese plate near the Andaman Islands suggest the Sunda Arc in this region to be low to intermediate stress subduction zone. (Gopala Rao and Krishna, 1996. J. Geophys. Res., in press). Western continental margin of India Study of closely spaced marine magnetic profiles in the northern Arabian Sea shows that most of the identified magnetic lineations in the Arabian Sea are segmented by oblique offsets representing pseudofaults associated with paleo-propagating ridges. The early Tertiary seaftoor spreading in the Arabian Sea was characterized by systematic ridge propagation probably caused due to influence of the Reunion hotspot - on the spreading segment. (Chaubey, et a/.,1996, in press). The calcareous deposits on the western shelf of India off Bhatkal, at 50-58 m depth occur as crusts, sheets, cylinders and reddish brown mudstones. This indicates that the particulate matter in the calcareous deposits were initially at the proximity of the coast and cemented by metastable calcites during the Pleistocene interglacial sealevel stands on the shelf. Pedogenic cementation process overprinted and developed them into eolianites and paleospls during the subsequent Late Pleistocene

sealevel regression. (Rao and Thamban, 1997. J. Geol. Soc. India, 49: 297-306) Genesis of apatite in the phosphatised limestones on the western continental shelf of India was studied. The apatite microparticles often adhere to clays and resemble fossilized bacteria hapetites. It appears that abundant flux was transported to the shelf at about 8,300 years B.P. which filled the pores / cavities of corals and coralline algae. Subsequently, microbial organisms colonized the sediment and filled pores of the limestones and favoured rapid precipitation of apatite locally by utilising organic phosphate and phosphate adsorbed on to clays. Phosphatization of the limestones is thus a short event in the Early Holocene influenced by microbial processes. (Rao and Lamboy, 1996, Mar. Geol., 136: 41-53)

Carisberg Ridge The Carisberg Ridge was surveyed using the muitibeam bathymetric system. The results show a ridge axial discontinuity with a broad axial valley, depth varying from 4500 to 2200 m. The back scatter amplitude data from muitibeam revealed that the rift valley is sedimented. Mantle rocks such as lherzolites, gabbros, serpentinites were collected from the inner rift valley wall indicating a shallow depth of mantle. (Mudholkar, et al., 1996. Inter Ridge News, 6, 34)

Environmental impact Assessment in Nodule Area Indian Deep-Sea Experiment The Indian Deepsea Experiment (INDEX) in the Indian Pioneer Area was initiated in 1995 to assess the possible environmental impact on the marine ecosystem due to seabed mining in the Central Indian Basin (CIB). Multidisciplinary studies on geological, biological, physical and chemical aspects were undertaken for establishing the baseline conditions in the CIB area prior to the benthic disturbance. The test and reference areas were identified for the benthic disturbance experiment using close grid bathymetric surveys and nodule abandance data. Detailed geochemical, sedimentological, biological, and geo-technical studies on sediments resulted in understanding the benthic conditions and the distribution of macro, meio and micro fauna. (Sharma, et al., 1996, communicated, ISOPE Proc.) Analysis of ocean currents obtained from the mooring of the current meter arrays (with Russian make POTOK current meters in the CIB area revealed considerable variability in the flow field at different time-scales (inertial to seasonal) even at near bottom depths. The magnitudes (directions) of monthly mean currents at nearbottom depth of 5100 m were estimated to be 3.0 cm.s -1 (104°) in April; 2.6 cm.s -1 (92°) in May; 2.9 cm.s -1 (53°) in June; 2.2 cm.s -1 (228°) in July; 1.3 cm.s -1 (201°) in August and 1.6 cm.s -1 (306°) in September. The preliminary analysis of CTD data collected from the CIB area indicated variations in the thickness of upper oceanic

mixed layer, decrease in surface salinity towards southwest part of CIB and strong near-surface halocline in the upper 25 m water column. A sub-surface salinity maximum and an intermediate salinity minimum around 75 and 1000 m depths were noticed in the area. The temperature and salinity variations were negligible below 2000 m depth. Analysis of chemical data measured from the waters of CIB area indicated low concentrations of nitrate and silicate in the surface mixed layer, while phosphate concentrations increased rapidly. This increase was associated with a corresponding decrease in dissolved oxygen. The shallow oxygen maximum (2.3 - 4.3 ml.!'1) was observed in the depth range 300 - 500 m. It was associated with higher pH, higher alkalinity and lower nutrient content. The deep waters were characterised by high oxygen, high pH and relatively lower content of nutrients. Water samples were analysed for dissolved trace metals. The metal maxima were associated with a maxima in nutrients and a decrease in pH and dissolved oxygen content, thereby indicating that like nutrients, trace metals were also released in the water column during the process of oxidation of organic matter from the surface water column. Zooplankton samples were collected from 11 stations along five transects including the four stations from the test site. The zooplankton biomass showed considerable variations from station to station and along the depth.

Traces of benthic activity in Pioneer area.


Numerical abundance of the fauna of the region showed that the test site supports a rich and varied assemblage of organisms. Generally low biomass values were found to coincide with low numerical density and vice versa. Mostly the zooplankton concentrated above the subsurface salinity maxima where the oxygen concentration ranged from 3.7 to 5.52 ml I-1. The WP net collection from deeper layers also showed a reduction in the volume of biomass as well as diversity of groups from 200-500 m exhibiting a general trend of dilution of organisms from the upper layers to lower layers. In general, the euphotic zone of the CIB is found to supports fairly rich and diverse fauna.

Sub-surface methane in-the eastern Arabian Sea High-resolution shallow seismic reflection data obtained from the continental shelf sediments off western India from 10°N to 22°N reveal the anomalous seismic signatures in the form of acoustic maskings of methane-rich horizons. A conservative estimate of the potential subsurface methane in these gas-charged sediments is of the order of 2.6 Tg, and its contribution to the atmosphere with an annual flux of 0.039 Tg CH4 appears to be quite significant. High seepage of methane from the seabed of the continental shelves should hence be considered for while estimating global oceanic flux of methane. (Karisiddaiah and Veerayya, 1996. J. Geophys. Res., 101:25887-25895). Evidence of Recent hydrothermal activity in the Central Indian Basin The Central Indian Basin (CIB) was considered to be inactive in terms of volcanic eruptions in the recent past. However,

work carried at NIO has provided evidence of recent volcano-hydrothermal activity in the CIB. On detailed investigation of 27 sediment samples from CIB, two samples occurring at the base of an intraplate seamount were found to have high concentration of volcanogenic hydrothermal material (vhm). The vhm consist of ochrous metalliferous sediments, nontronite, volcanic spherules and glass shards. The metalliferous sediments are akin to their counterparts in the active hydrothermal sites in the Pacific Ocean in terms of colour, chemistry and formation. The volcanic spherules which are dominantly magnetite and resemble extraterrestrial spherules are products of liquid immiscibility of a silicicbasic magma or of hydrovolcanic activity. Based on the age of the associated radiolaria with the vhm, an age of ~10 ka is suggested for an episode of volcanic-hydrothermal activity in the CIB. The present finding might have relevance for the type and eruptive mechanism of seamounts and the addition of elements to sea water and manganese nodules and crusts in the CIB. (Iyer et al.,1996. Deep-Sea Res., in press).

Application of biochemical & molecular techniques to characterise ocean trophic dynamics Nitrogen sources from mangrove detritus Studies on carbon and nitrogen contents of leaves, roots and pneumatophores of Rhizophora apiculata, R. mucronata, Avicennia marina and A. officinalis and of the litter fractions of major species of mangroves (A. marina, A. officinalis and Sonneratia alba) are being carried out. Remineralization studies of leaf litter of 4 mangrove species (R. mucronata, R. apiculata, Sonneratia alba and A. officinalis) are in progress. Experiments on uptake and assimilation by phytoplankton of nitrogenous nutrients of the water column and sediment, are being carried out at monthly intervals in a mangrove ecosystem. Ammonium was found to be the most preferred nutrient by phytoplankton with a specific uptake rate of 0.201/h, an absolute uptake rate of 2966 ng-at/l/h and a high assimilation index of 571.2 ng-at N(mg chl)-h-1. Nitrate uptake ranked next in importance (specific uptake = 0.01/h), followed by nitrite uptake (0.0004/h) which was insignificant. As with the water column, ammonium uptake was the highest among the four nutrients, with a specific uptake rate of 0.02/h, an absolute uptake rate of 386.67 ng-at g-1 h-1 and an assimilation index of 16.12 ng-at N (mg chl)-1 h-1. Specific nitrate uptake was very low (0.0004/h). Role of exopolysaccharides in particle sedimentation Dissolved carbohydrates in the Bay of Bengal and the Arabian Sea showed little variation of monosaccharide

concentrations with depth. Polysaccharides were the most abundant form of dissolved carbohydrates. Carbohydrate concentrations showed significant positive correlations with chlorophyll a (in the upper 150 m), nitrate and phosphate concentrations and a significant negative correlation with dissolved oxygen concentrations. Higher abundance of carbohydrates was found associated with the dissolved oxygen minimum layer. Macroaggregates from various sources of organic carbon serve as a food source for particle feeders and benthic organisms. The chemical composition of macroaggregates showed that mangrove leaves are richer in carbon than nitrogen. Whereas, those obtained macro algae were fairly enriched in nitrogen. As such, macroaggregates derived from macro algae may be a preferred source of food for benthic and other organisms due to enrichment of nitrogenous organic matter. Macroaggregates of algae did not show any particular trend and varied from species to species. Older aggregates of all the species showed a increase in nitrogen and a decrease in carbon content. Such differences in carbon and nitrogen content can play an important role in determining the food values of the macroaggregates. Studies on microfilm formation in relation to physico-chemical, biological and biochemical parameters Variability in microfilm formation Fiberglass and cupro nickel panels were suspended in the water column in coastal station (Dona Paula Bay). The results indicate the dominance of centrales over pennates whereas in the fouling film the reverse was evident. This difference could probably be due to the capability of pennates to foul more readily than centrales as they possess raphe which

help in gliding and crawling over the surface. The diversity of diatom population indicates that the recruitment of diatom cells is not fully controlled by its diversity in the water column. Influence of exopolymers on cyprid metamorphosis of Balanus amphitrite Exopolymers secreted by bacteria can also play a major role in the recruitment of larvae of fouling organisms, probably by providing inducing/inhibitory chemical cues. The extract of adult Balanus amphitrite and the exopolymers of the bacteria colonizing B. amphitrite in nature on the cyprid metamorphosis of B. amphitrite was tested. The results obtained indicate that the addition of exopolymers as well as adult extract promoted settlement of cyprids. Physiology of Wood Borers Wooden panels of Mangifera indica were exposed for different periods. We found Martesia striata and Nausitora hedleyi to be the dominant forms of wood borers. The effect of temperature and salinity on embryonic and larval development of Martesia striata was evaluated. The maximum metamorphic success was observed at 30. The thriving duration of the different instars was influenced by both temperature and salinity.

Indo-German Particle flux studies Two sediment trap mooring samples in the central and northern Bay of Bengal were analyzed for planktic foraminiferal abundance. This study has revealed that there are 26 species of planktic foraminifera present of which eight accounted for over 90% of the total foraminiferal flux. In the total, particulate flux of <1 mm size was


the largest component and generally increased with water depth. The total participate and planktic flux display similar bimodal distribution patterns related to the monsoon. The highest fluxes were recorded during the SW monsoon. The fluxes during the northeast monsoon are elevated but not to the level seen during the SW monsoon, with G. bulloides dominating the foraminiferal flux. The overwhelming proportion of G. bulloides in the foraminiferal assemblage is suggestive of upwelling activity in the western Bay of Bengal region during the SW monsoon. The reduced productivity of foraminiferal species in the northern Bay of Bengal is related to the injection of fresh water resulting due to the precipitation associated with SW monsoon. Neogloboquadrina dutertrei, Globigerinella rubescens exhibited elevated fluxes in the lower

salinity region. Foraminiferal productivity in the Bay of Bengal is one order of magnitude lower than in the Arabian Sea. The temporal distribution patterns of G. bulloides and its significance in different oceanic regimes in the Northern Indian Ocean has been investigated. G. bulloides exhibited a bi-modal distribution pattern related to the summer and winter monsoons. Its fluxes increase from east to west in the Arabian Sea and from north to south in the Bay of Bengal. Particle flux data obtained by time series sediment traps deployed over the years in the Arabian Sea were compared with the wind speeds computed from satellite data. We have inferred that there is a strong relationship existing between physical and biological processes related to the SW monsoon in the Arabian Sea. This enabled

us to recognize the well known upwelling system along the coasts of Somalia and Oman as well as open ocean upwelling at the beginning of SW monsoon. The coastal and open ocean upwelling are most effective in transferring biogenic matter to the deep sea during SW monsoons of moderate strength.

Scientific Cruises


During the year 14 cruises were undertaken, eleven on board ORV Sagar Kanya and the remaining on the chartered Russian vessel A.A. Sidorenko. Five cruises were for collection of geological and geophysical data and for environmental impact assessment studies in the application area (Central Indian Ocean Basin) under the project "Surveys for polymetallic nodules". Two cruises were exclusively for "JGOFS - India Programme" and one for validation of data on ocean colour collected on board the Indian Remote Sensing Satellite IRS P3. We also undertook one cruise in the Bay of Bengal to document the seasonal and annual variability of thermohaline properties and circulation features for World Ocean Circulation Experiment (WOCE) programme. ORV Sagar Kanya (owned by the DOD, New Delhi) Overall length: 100.34 m, Breadth: 16.4 m, Capacity: 32 Scientists, Endurance: 45 days. We continued regular pollution monitoring along Ratnagiri-Goa under Coastal Ocean Monitoring & Prediction System (COMAPS) programme on board CRV Sagar Paschimi.

The snapshot observations and preliminary results of these cruises are: · Surface waters of Andaman Sea saturated with atmospheric CO2 indicating that the whole region acts as a source of CO2 with a net flux to the atmosphere. · Central and symmetrical magnetic anomalies over the Carlsberg Ridge segment, the former one conspicuous with 500 nT amplitude. Both these anomalies reveal the age of the crust to be between 0 and 4.77 my. · The sediment temperature beyond 27°C in the axial valley in the Carlsberg Ridge region suggest the possibility of hydrothermal source nearby. · "A Front like structure" at 18°N in the northern periphery of the northern anticyclonic gyre in the central and northern Bay of Bengal. · A striking similarity in distribution of temperature, salinity and light transmission in the upper 200 m water column along 18°N.
