(HZL), Udaipur and leaching compaigns were undertaken.
* Manganese recovery from nodules and waste management
aspects were taken up by NML (J) and RRL (B) .
COASTAL ZONE AND ISLANDS
Marine Satellite Information Service(MARSIS):
MARSIS is designed to develop capabilities for retrieval of Ocean data
from satellite imageries, to generate useful Ocean data products and to
disseminate them to the end users on an operational basis.
The following progress was made during 1995-96;
* SST and PFZ maps were generated and disseminated regularly.
PFZ dissemination centres increased to 174.
* Wet-land maps for Karnataka (13 maps), Goa (6 maps) and
Maharashtra (29 maps) were developed.
* Shore-line change maps for Goa (6 maps), Gujarat (60 maps) and
Andhra Pradesh (50 maps) were developed.
* Preliminary studies on ocean surface wind vector from ERS-1
scatterometer were completed and fortnightly and monthly mean
maps of wind vector for one year was generated. Operational
production of these maps are now possible if regular scatterometer
data is available.
* An algorithm for estimation of latent heat flux using surface level
humidity and SST data was developed, and taken up for validation.
* The project on internal waves was completed. Internal waves which
were characterised using the IRS and ERS - 1 data have many
potential applications for off-shore operations, sub-marine
communications, ocean productivity, etc.
* About 26 drifting buoys (19 Low cost + 7 Multiparameter) were
deployed in the Arabian sea, Bay of Bengal and Equatorial Indian
Ocean for collection of in-situ Met-Ocean data. 3 Multiparameters
and 2 directional wave track buoys were moored off the Goa coast
and Gulf of Kuchch for collection of surface data and wave data.
* A model explained in the intensification of cyclones in the Bay of
Bengal was developed, which will help in predicting cyclones.
* A pilot project on the creation of Coastal Zone Information System
(CZIS) for Rameswaram Taluk and Mahanadi Estuary mangrove
region was completed. An atlas of the Indian Ocean SST which
depicts the monthly and seasonal average distribution of SST and
another atlas on "chlorophyll -a" of the Northern Indian Ocean was
prepared.
Sea Level Monitoring And Modelling (SELMAM):
In order to assess variations in the sea level due to climatic and other
changes and impact of such variations on the coastal belt of India, a project
was initiated for establishment of modern tide gauges for measurement of tides
more accurately and preparation of contour maps of the coastal region. The
data collected from the tide gauge stations and coastal maps will form the
basis for developing predictive models for assessing the effect of sea level
variations and storm surges on the coast. Some of the major accomplishments
during 1995-96 were:
* The cabin construction at Kavaratti, Madras, Kochi,
Visakhapatnam and Tuticorin was completed
* Installed acoustic tide gauges at Goa, Port Blair and Madras.
Commissioned the tide gauge stations at Port Blair and Madras
* Fabricated 7 improved stilling wells.
* Fabricated 7 digital type Float gauges.
* Held an international workshop on Sea Level Data Analysis for
Asia-Pacific countries at Survey of India.
* Completed scribing, Scripting and final printing of the coastal
area maps for the stretch Nellore to Machilipatnam.
National Data Buoy Programme:
Met-Ocean Data buoy is a comprehensive long-term marine
monitoring programme designed particularly to make the real-time data on
various meteorological and oceanographic parameters available to the users
such as National Institute of Oceanography (NIO), India Meteorological
Department (IMD), Oil and Natural Gas Commission (ONGC), etc. The
programme envisages collection of data on meteorology and oceanographic
environment such as atmospheric air pressure, wind, surface temperature ,
salinity, wave etc. on time series basis. The data from the buoys can be
telemetered via INMARSAT or INSAT to the shore station. National data buoy
programme envisages mooring of twelve data buoys at selected locations in the
coastal waters of India (i.e., the Arabian Sea and Bay of Bengal). Four out of
12 buoys will be equipped with additional water sensors to monitor
continuously the water characteristics and ocean currents.
The department constituted a Tender Evaluation Committee to evaluate
the technical and financial offers of two Norwegian companies. The Committee
met twice and furnished recommendations. An EFC Memo for implementation
of the programme was prepared and circulated.
Coastal Ocean Monitoring & Prediction System (COMAPS):
The vast marine environment has long been used as a site for the
disposal of wastes. In some cases the polluted material is discharged directly
into the sea and in other cases the pollutants reach the rivers and estuaries
and finally end up in the sea. Pollution of the marine environment and its
effects on the living resources has assumed considerable importance in the
recent times.
Since most of the pollutants enter the coastal waters through river run-
offs and estuarine discharges, with the exception of oil pollution, most of the
studies are limited to the estuarine and nearshore waters. Most of these
substances have varying degrees of toxicity to both marine organisms and man
and a great public health importance constituting a serious threat to the future
utilisation of living resources. These pollutants pose special problems in
environmental toxicology because of their extreme persistence and bio-
accumulation. In order to monitor the levels of various marine pollutants in the
coastal and offshore waters of the country and to assess the health of our seas,
a programme on Coastal Ocean Monitoring and Prediction Systems (COMAPS)
is under implementation since 1991.
* Data on 25 pollution parameters were collected at 77 locations
with the help of 11 Institutions to determine the trend of increase
or decrease of pollution.
* In order to assess the performance of the COMAPS units of the
Department two inter-laboratory exercises were conducted and a
Workshop on "Nutrients in Seawater" during 13th-17th
November, 1995 was organised.
* Stage-1 of the mathematical model, to study the flow pattern of
pollutants in Thane Creek was completed.
* As a result of monitoring, areas of low, medium and high
concentrations of pollutants have been identified and the areas of
high concentration of pollutants are being monitored intensively.
* Improved infrastructural set up in all the COMAPS units was
created.
* The National Marine Data Centre on Marine Pollution at the
Regional Centre of National Institute of Oceanography, Bombay
was established to disseminate the information on status of
marine pollution in the country.
Island Development Programme:
The main objective of this programme is to demonstrate the technology
of shrimp culture in acid sulphate soil, mixed culture of finfish and coral reef
rejuvenation.
During the year 1995-96 the following activities were taken up.
* Training of fishermen on shrimp culture.
* Demonstration of technique for culture of shrimp culture under
acidic soil conditions.
* Experiments on techniques for deploying artificial structures as
the substratum for rejuvenation of coral reef.
Marine Instrumentation and Systems:
Under this programme facilities are provided by the Department to the
fishermen in coastal areas for improving the communication between the
fishing vessels and the shore station, so that they are able to effectively
communicate to the nearest land mark when they are in distress and save their
lives.
Nine shore stations which were commissioned during 1994-95, were
operationalised. The Annual Maintenance Contract for maintaining and
servicing radio telephones at the shore stations and walkie-talkie sets
distributed to the fishermen was awarded to different firms for a duration of
one year. The basic work for establishing shore to fishing vessel
communication system in the other coastal states and Union Territories viz. W.
Bengal, Orissa, Pondicherry, A & N Islands in the East coast and Maharashtra,
North Goa and Lakshadweep islands in the west coast, was initiated. With a
view to assisting the small-scale mechanised sector in locating the fishing
ground and location of the vessel at sea, orders for developing Integrated Global
Positioning System Navigator-cum-Fish Finder, were awarded to M/s
Aerospace Ltd. and Bharat Electronics Ltd., through M/s Electronics Research
& Development Corporation, Thiruvananthapuram.
Research, Development and Specialised Manpower:
The objective of the programme is to provide support to the research
projects and develop the specialised manpower in the field of oceanography.
During the year 1995-96 support was continued to 10 institutions/universities
working on the national project "Drugs from Sea". Besides 17 ongoing projects
were also supported. During the year 1995-96, seven new projects were
recommended by the Research Advisory Committee.
The Department was also granting fellowships/associateships for
undertaking research in the various fields of ocean sciences. There are at
present around 60 research personnels who presently working in various
universities and institutions. During the year 1995-96, 18 new Research
Fellowships were approved by the Department
Drugs from Sea:
The National Project on Development of Potential Drugs from Sea has led
to identification of 17 potential organisms having properties as anti-fertility,
anti-microbial, anti-viral, anti-diabetic, anti-malarial, anti-hypertensive, anti-
inflammatory, anti-anxiolytic, anti-amoebic and larvicidal agents. Out of these,
five organisms which showed potent activity as anti-diabetic, anti-viral, anti-
amoebic, anti-anxiety and larvicidal agents, have been identified for developing
atleast two herbal drugs in the next few years.
INFRASTRUCTURE AND SHIPS
National Institute Of Ocean Technology (NIOT):
The National Institute of Ocean Technology (NIOT) was established in
1993 at Madras as an autonomous society under the administrative control of
Department of Ocean Development (DOD) for undertaking technology
development in the ocean sector.
The Institute is undertaking research activities relating to ocean
technology under four major mission mode projects i.e., Ocean Energy, Deep
Sea Technology & Ocean Mining, Coastal Zone Studies and Marine
Instrumentation.
Ocean Energy:
A mathematical model for optimisation of the spacing of the Caisson for
Thangasserry breakwater in Kerala was developed and structural design of the
caisson and details of construction completed. A 5 KW excitation controller for
induction generator to deliver constant power output was developed. A design
for a Slurry Pumping System using Jet pump was completed.
Deep-Sea Technology and Ocean Mining:
Environmental Impact Assessment (EIA) studies of shallow water mining
was taken up. A special inspection vehicle was developed to inspect the
underwater tunnels.
Coastal Zone Studies:
NIOT's focus in this area is technology oriented dealing with
development and application of mathematical models to predict and monitor
the changes of the coastline.
A base line survey to determine the effect of discharge of the effluent
from coastal aquaculture farms located all along the Indian Coast, was
completed.
Marine Instrumentation:
Relatively inexpensive instrument was developed for the measurement of
velocity Profile. A Consultancy work was taken up to conduct geo-technical
investigations on various bore hole samples relating to Ennore Coal Port in
Tamil Nadu.
Coastal Research Vessels:
To facilitate systematic collection of water and sediment at all desired
locations and onboard analysis of the mandatory parameters, steps were taken
to acquire two Coastal Research Vessels. These vessels also facilitate collection
of samples. Laboratory facilities along with analytical instruments are also
proposed to be built in for onboard analysis of several physico-chemical, and
biological parameters. These vessels will be used by the COMAPS institutions,
National Institute of Ocean Technology and other academic institutions.
In order to attain the desired draft and stability, a design review was
made and a few mid-term corrections in the design were carried out.
Construction of vessel upto 90% level was completed as against the
anticipated 80%. Meanwhile, procedures for the selection of a shipping
company to run, maintain and manage the vessels were initiated and the
companies were shortlisted. Recruitment of staff for the Vessel Management
Cell at NIOT, Madras was completed.
International Obligations & Cooperation Programmes:
Contribution to International commissions and organisations such as
Inter-Governmental Oceanographic Commission, Commission on Conservation
of Antarctic Marine Living Resources, Scientific Committee on Antarctic
Research, UNCLOS and Regional Seas Programme etc. were continued.
The JGOFS is an established core programme of International
Biosphere-Geosphere Programme (IGBP) to determine carbon flux in the world
oceans with a view to establishing the role of Oceans in governing atmospheric
CO2 content. The Indian component of JGOFS is aimed at assessing the role
of the Arabian Sea as a source/sink of CO2 and other green house gases
which primarily consist of four major components namely biological
oceanography, geo-chemical studies, physical oceanography studies, particle
and sedimentation studies etc. The institutes, viz., National Institute of
Oceanography, Goa; National Chemical Laboratory, Pune; and Physical
Research Laboratory, Ahmedabad; are participating in the JGOFS(India)
project.
Under the programme, 2 multi-disciplinary oceanographic cruises,
approximately of 30-days each on board ORV SAGAR KANYA were completed in
the Arabian Sea, covering monsoon and premonsoon seasons.
Information and Awareness
National Ocean Information System (NOIS):
India has a long coastline of 7,500 km, including as many as 1256
islands with many major cities and towns located in the coastal areas and
about twenty five percent of the country's total population is inhabited there,
depending directly or indirectly on coastal waters for their livelihood and
recreation. A large number of agencies, including research institutions,
academic establishments, survey and oil exploration agencies in the country
are dealing with a variety of ocean and ocean related activities. The activities
generate enormous amount of data and information in various fields relating to
Ocean Science and Technology. In this context, to develop and disseminate the
data products for the benefit of scientists and policy makers in the country, the
Department implemented a National Ocean Information System (NOIS)
programme, under which:
* Infrastructure facilities in all the 13 Marine Data Centres (MDC)
ere developed.
* Micro Earth Stations (MES) to connect MDC through the satellite
based National Informatics Centre (NIC) Network at 11 MDC were
established.
* Hardware and software requirements of the MDC were finalised.
* Data formats for data storage and retrieval were finalised.
Exhibition & Fairs:
This programme is aimed at inculcating the sprit of scientific temper and
awareness on Ocean Science & Technology among the masses. Accordingly,
exhibitions are organised wherein the activities of the Department and the
programmes are highlighted. The Department participated in the National
Science Day exhibitions at different schools in Delhi, Science Exhibition in
Jamia Milia Islamia, Jamia Nagar, New Delhi and Exhibitions on Oceans at
Vasco, Goa Exhibition at Jamilia Millia Islamia, New Delhi during the financial
year 1995-96,
Marine Aquaria, Oceanaria etc.:
A number of endangered marine species like horseshoe crabs, olive
ridley turtles and coral fishes live in the coastal and near shore waters. The
only way to create awareness among the public on marine life is to display in
live condition their behavioural pattern in a unique facility like oceanarium.
The advancement of submarine structural technology during the last few years
has led to creation of under-sea observation systems such as aquaria,
oceanaria, etc. This permits the viewer to see the living habitats of marine
animals under the natural conditions. In order to have this facility in the
country an oceanarium in the private sector on Build, Own, Operate and
Maintain (BOOM) basis, was planned to be set up.
The activities related to promoting establishment of an oceanarium in
Goa on BOOM basis was carried out. Global tenders were invited through
leading news papers. Suitable site for the establishment of oceanarium at
Miramar Beach, Goa was identified. Request for Proposal document was
drafted and assessed by the Project Management Committee, constituted by
the Department. List of animals to be displayed and the minimum facilities
required in the oceanarium were finalised. Based on the response received,
copies of the Request for Proposal document were sent and technical and
financial bids were evaluated.
Exploration of Living and Non-living Resources
Department carries out the task of survey to locate and map the
resources potential, living and non-living with the help of its own vessels ORV
Sagar Kanya and FORV Sagar. In year 1995-96, ORV Sagar Kanya and FORV
Sagar Sampada were instrumental in carrying out the multidisciplinary survey
and exploration activity in Bay of Bengal and Arabian Sea with the
participation of various CSIR and ICAR institutes viz. NIO, NGRI, PRL NCL,
CMFRI, IFP, CIFT etc.
FORV SAGAR SAMPADA is designed for fisheries and oceanographic
research in the Exclusive Economic Zone of India and the contiguous high
seas. The vessel was ice-strengthened to give support to India's Antarctic
scientific programmes for working as far south as 60§ S latitude. Marine
Fisheries Resources Research is the principal function of the vessel. It is well
equipped for locating fishery resources, assessing the extent of their
distribution and quantifying the fish stocks in the column waters and level
bottom through effective use of a multiplicity of fishing gear such as bottom
trawl, pelagic and midwater trawls and long-line and aided by modern
underwater acoustics and electronic data processing systems.
Major achievements of FORV Sagar Sampada during 1995-96 were:
* Thirteen cruises were carried out with the participation of 29 organisations.
* Physical and chemical oceanographic data for quantifying
North-South transport of biogenic element, were collected.
* Inter-annual variability of hydrographic conditions during the
North East monsoon in the Eastern Arabian Sea and redox
chemistry of nitrogen system with the oxygen poor water of
the Arabian sea, investigated.
* The effect of chlorinated hydrocarbon compounds, was
assessed under marine pollution studies.

* Arabian Sea is found to be a region with extremely delicately
poised biogeochemical balance that makes it very sensitive to
human interference.
* 33 m Bobbin trawl found suitable for demersal trawling in
continental slope with wavy bottom.
ORV Sagar Kanya has a total of 13 laboratories spread over three decks
and various other additional work spaces. The laboratories are fully equipped
with the basic equipment for oceanographic research in geology, geophysics,
meteorology, chemical and physical oceanography and marine biology.
Major achievements of ORV Sagar Kanya during 1995-96 were:
* Retrieval and re-deployment of sediment traps in Arabian Sea
and Bay of Bengal to understand and evaluate the role of
physico-chemical and biological processes by quantifying
particulate flux sinking to the ocean floor.

ANTARCTIC RESEARCH PROGRAMME
During the period under review, the XVI Indian Antarctic expedition was
launched on 12 December, 1996 with the aim towards achieving a part of the
long term scientific objectives, to be pursued in Antarctica by the Department.
The scientific experiments envisaged to be undertaken during this
expedition are as follows:
Atmospheric Sciences:
(i) Vertical profiling of ozone and dynamics of ozone hole: The National
Physical Laboratory has designed a state-of-the-art experiment by using a
Laser Heterodyne System (LHS) designed to yield the vertical profile of ozone
and other minor trace gases in the atmosphere upto a height of 60 km.
(ii) Fluxgate Magnetometer Studies: This is an ongoing study to be
continued by the Indian Institute of Geomagnetism, Bombay and is designed to
understand the dynamics of mobile current systems in the Antarctic
atmosphere.
(iii) Climatological and Meteorological Studies: This is being pursued by
Indian meteorological Department since the first expedition with the aim to
build up an Antarctic climatological data bank on a decadenal scale. This
information will be used to generate meteorological models to understand the
patterns of Antarctic circulation in the context of global and Indian weather
systems.
(iv) Electrical Conductivity and Aerosol Particle Distribution Studies: This is
a new experiment to be initiated by the Indian Institute of Tropical Meteorology,
Pune. In this experiment, it is proposed to measure the atmospheric electric
field along with size distribution of fine aerosol particles over Antarctica and
during the sea voyage.
Earth Sciences:
(i) Geological mapping and Glaciological Studies: Geological mapping will
be carried out to cover an unmapped area of 100 sq.km. in the Kurze and
Holtedahl ranges of Orvin II mountains during the XVI Expedition. Samples will
be collected from Schirmacher hills for laboratory analysis in order to
undwerstand the petro-geochemical evolution.
(ii) Geological Evolution of Schirmacher Hills, East Antarctica : This is a
multifaceted study initiated by the Deptt. of Geological Sciences, Jadavpur
University in the XV Expedition. The aim of this ongoing project is to
understand the structural, petrological, geo-chemical and geo-chronological
signatures in the rocks of the Schirmacher Oasis so as to elucidate the history
of crustal evolution of the area.
(iii) Snow Drift and Albedo Studies in Antarctica: This is an ongoing study to
be continued by Snow and Avalanche Study Establishment (SASE) for
understanding the net energy exchange budget between the atmosphere and
the variety of terrains encountered in Antarctica. The reflectivity of the snow
cover surface i.e. the albedo, which is the most crucial factor in controlling the
energy balance, will be measured through a number of experiments under
different physical conditions.

COSTAL ZONE AND ISLANDS
Coastal Ocean Monitoring & Prediction System (COMAPS):
Based on the data collected from 1991 to 1996, intensive monitoring of
pollutants in 32 locations designated as hotspots is being done for 2 seasons a
year to determine the trend of increase or decrease of pollution as given below :
* Areas of clean sea water quality : The sea coast beyond 2 Km
along the coastline of India except off Bombay is clean and
conform to quality of clean waters. This is primarily due to the
fact that the levels of dissolved oxygen and other parameters are
fulfilling the requirements of clean sea water.
* Areas of low concentration of pollutants : In Bedi, Vadinar and
Kandla of Gujarat, Ratnagiri in Maharashtra, Mandovi and Zuari
in Goa, Mangalore Port in Karnataka, Cannanore and Calicut in
Kerala, Cuddalore in Tamil Nadu and the West Bengal coast, the
concentrations of dissolved oxygen was fairly good and other
toxic elements like ammonia, heavy metals in sediments and biota
were slightly higher (about 15%) than the clean waters and hence
they have been classified as areas of low concentration of
pollutants.
* Areas of Moderate Concentration of Pollutants : In Porbandar,
Damanganga estuary, and Vapi industrial estate in Gujarat,
Mangalore coast in Karnataka, Kochi backwaters, Quilon and Veli
in Kerala and Tuticorin and Arumuganeri in Tamil Nadu, the
levels of dissolved oxygen were moderate to normal and however
some of the elements like ammonia, pathogenic bacteria in sea
water and heavy metals in sediments showed higher
concentration (about 25%) than the normal values. Hence, these
areas are classified as regions of moderate concentrations of
pollutants.
* Areas where concentration of Pollutants may become high in near
future : In Veraval Port, in Gujarat, Ulhas, Versova Creek, Mahim
Bay and Thane Creek in Maharashtra , Visakhapatnam Harbour
and Kakinada Bay in Andhra Pradesh and Puri in Orissa, the
concentrations of dissolved oxygen were `nil' to `low' during low
tide period. Their levels improved only moderately (30-50%)
during the high tide period. Further, the levels of toxic metals
like cadmium and lead were high in sediments in some locations
(like Thane creek). If no control measures are exercised now, the
areas will become regions of high concentration of pollution in
another 5 to 6 years.
* The mathematical model on Thane Creek was developed and field
tested by using the field data collected under this programme.
* Infrastructural facilities were strengthened in all the COMAPS
units.
* To ensure the quality data being collected under the programme,
intercalibration exercises conducted by RRL, Trivandrum, twice a
year.
Pollution levels have been periodically brought to the notice of the
concerned State Pollution Control Boards for remedial action.
Island Development Programme:
The following activities are expected to be performed during the year

Commissions like CCAMLR, UNCLOS, Regional Sea programme and
organisations were continued. With the coming into force of UNCLOS, India
became entitled to delineate the continental margin beyond EEZ of 200
nautical miles, which can extend our sovereign rights over the marine living
and non-living resources of the continental margin. Preparatory work for
initiating a new scheme on Delineation of continental shelf was taken up.
Being the Member of Commission for Conservation of Antarctic Marine
Living Resources (CCAMLR), the Department initiated actions to develop
capabilities to exploit living resources specially krill in the Antarctic waters.
The Department supported a few programmes in developing countries, like
assistance towards setting up of tide gauges in Vietnam. To promote the
regional cooperation in the field of environment management in South Asian
Region, an action plan was finalised and was adopted by South Asian countries
viz. Bangladesh, India, Maldives, Pakistan and Sri Lanka.
Under Intergovernmental Oceanographic Commission(IOC), the
Department hosted a meeting of the IOC Regional Committee for the Central
Indian Ocean (IOCINDIO) during 20-22 Nov. 1996. A Regional Workshop on
Global Ocean Observing System (GOOS) Capacity Building was also organised
in Goa during 18-19 November 1996.

till December `96. The main area of survey/study was in the Arabian Sea. Nine
organisations participated as user agencies in the above cruises. Five cruises
were undertaken by the CMFRI for the assessment of cephalopod and
mesopelagic resources, between Latitude 7deg - 22deg , 30' N and 76deg 30' to 66deg E
in the Arabian Sea. Data on Oceanographic parameters such as salinity,
dissolved nutrients, SST, dissolved oxygen, plankton distribution etc were also
collected during the cruises.
The shoals observed in the survey area included mainly of tuna, dolphins
etc, besides juveniles and young ones of a variety of other fishes. The catches of
Nemipterus spp and Priacanthus hamrur were recorded off Kasargod and
Gujarat coast respectively.
Two cruises were undertaken by NIO to study the bio geo-chemical
process within the Arabian Sea suboxic zone. Apart from collecting the
hydrochemical and hydrographic data, to get a measure of seasonal and inter-
annual changes, process-oriented studies were also undertaken during the
cruise. These crusies generated additional data on Nitrogen/Argon gas ratio
especially in the deeper water and investigated its spatial variability. The
cruises also revealed dual isotopic position on concentration of Nitrous Oxide.
The high quality of hydrographic data generated would be useful for the fishery
scientists to study mesopelagic fish such as myctophids in regulating carbon
fluxes and mid water depth in bio-geo-chemical cycling. Studies also included
hydrographic aspects, sediments and zooplankton collections and fish samples
covering the zone between Honovar to Karwar, off Goa and international
waters. Altogether 24 species of fishes were collected from different stations to
identify and quantify the levels of contamination of various chlorinated
hydrocarbons.
Indian Antarctic Krill Expedition:
The First Indian Expedition for assessment of krill and other marine
living resources in the Antarctic waters was completed in the second week of
March `96. The samples of krill were distributed to the Integrated Fisheries
Project - Kochi, FSI - Mumbai, NIO - Goa, CIFT - Kochi and CFTRI - Mysore.
The IFP Kochi developed products such as krill sausages, krill ball, krill burger,
krill cutlet, krill kabab, canned krill ball, dried krill, krill chutney powder,
seasoning, meat textured protein concentrate, krill meal, feed and pickles and
have been test marketed. The byproducts developed were chitin and chitosan.
Proximate composition analysis showed that the products have excellent
nutritional properties. The calorific value ranged from 117 to 240K calories.
The shrimp feed prepared out of krill meal was rated equal in quality to
imported feeds and much superior to indigenous feed with respect to physical
and chemical quality characteristics. The results of this expedition were
presented and discussed in a one day workshop during December `96 at
Mumbai.

institutions etc.
Financial Requirements: Rs. 15.88 crore (Non-Plan)
New Activities / Tasks During 1997- 98
A. Integrated Coastal and Marine Area Management (ICMAM):
The coastline of India has a variety of habitats such as vast stretches of
backwaters, estuaries, lagoons, bays, mangroves, coral reefs, seagrass and
algal beds, etc. These areas are considered as critical habitats as they are
unique, exhibiting high degree of biodiversity, and supporting diverse flora and
fauna. There is an increasing pressure to utilize the resources around coastal
areas including the critical habitats for various purposes like development of
harbour, urban sites, industries, waste disposal systems and aquaculture
sites. Due to overuse and abuse, both biological diversity and biomass of the
systems are undergoing rapid decline and changes. DOD, being proposed as
the nodal Department for implementation of the Ocean Regulatory Zone (ORZ)
notification will undertake the following preparatory activities/projects which
are essential to this programe:
Financial Assistance to Coastal States and Union Territories for
Implementation of ORZ Notification and ICMAM Plans:
State Governments need technical and financial assistance to build up
facilities and for manpower traning for the implementation of ORZ notification
as well as ICMAM plans. It is proposed to provide funds for non-recurring
items. All the recurring expenditures to operate the projects cells will be met
by the states.
Establishment of Administrative and Technical Cells of DOD:
For implementation of ORZ and monitoring the activities, establishment
of administrative and technical cells are essential. This activity will be carried
out utilising the services of Central and State Pollution Control Boards and
other institutions including the Non-Governmental Organisations (NGOs).
Capacity Building :
Technical activities relating to ICMAM in the following areas will be
taken up in order to develop expertise in the country. This part of the project is
expected to be funded by the World Bank.
Development of GIS Based Information System for Critical Habitats
(CHIS) in the Coastal Marine Areas and Identification of No-
Impact Zones:
The critical habitats like mangroves are priority areas that need to be
conserved and managed sustainably. Therefore, it is proposed to develop a
computer-based system composed of comprehensive and integrated set of data
designed for decision-making using modern techniques like Geographical
Information System (GIS), which will be useful for preparation of Integrated
Coastal and Marine Area Management Plans (ICMAMP).
Preparation of model Integrated Coastal and Marine Area
Management Plans (ICMAMP):
To cater to the need of the coastal states two / three model plans are
proposed to be developed to achieve the ecological balance and sustainable
economic development.
Waste Assimilation Capacity and Ecological Modelling of selected
Coastal Areas:
Development of a predictive capability for a given coastal area requires
assessment of the environmental capacity to assimilate defined pollutants.
Therefore, Waste Assimilation Capacity of each selected area will be developed
and ecological modelling like Hydrodynamic Modelling, Pollutant Transport
Modelling, Water quality modelling, Pathogenic bacteria Modelling, and
Phytoplankton Modelling will be carried out.
Development of Guidelines for Environmental Impact Assessment
Studies for Marine, Coastal and Developmental Activities:
The proposed project aims at developing comprehensive guidelines for
offshore and coastal structures, ports and harbours, process industries, marine
wastewater disposal, tourism, beach and shallow water mining and
aquaculture activities. A separate cell to implement these projects will be
established in Madras, the capacity building projects, have been funded by the
World Bank.
Financial Requirements : Rs.9.00 crore.
B. Marine Biodiversity
To ensure ecological balance and sustained food production,
preservation and conservation of marine biodiversity is one of the most
essential tasks. In order to fulfill the lacuna in investigations relating to the
assessment of marine biodiversity, it is proposed to initiate a new scheme
during 1997-98 on Marine Biodiversity with due emphasis on assessment of
biodiversity and formulation of strategies for its conservation and sustainable
use.
Qualitative and quantitative investigations on the occurrence and
distribution of Marine flora and fauna in the estuaries, creeks and territorial
waters;Development of a data base which will form a base for providing
information on Marine biodiversity to the proposed Integrated Coastal Marine
and Area Management (ICMAM) Plans; Impact of various activities on marine
biodiversity through on-going programmes like COMAPS; Preparation of
management strategies for conservation and sustainable use of marine
biodiversity; and the activities proposed to be initiated.
Financial Requirements : Rs.0.05 crore.
C. Delineation of Outer Limits of Continental Shelf:
In accordance with the stipulations of the United Nations Convention on
the Law of the Sea, it is mandatory to submit the data for a claim to extend our
continental margin beyond the Exclusive Economic Zone of 200 nautical miles,
within ten years from the date of coming into force of the Convention.
The convention came into force on 16 Nov. 1994, and India ratified the
same in June 1995 and the need has now arisen to delineate the outer limits of
our Continental Shelf in accordance with its provisions. India is likely to gain
an additional area of about 1.5 million sq.km outside the Exclusive Economic
Zone, where the inherent rights of India can be duly exercised for exploration
and exploitation of the living and non-living resources.
A larger continental margin apart from exploitation of the resources
therein, also allows the country to lay submarine cables and pipelines, which
are important for communication purposes. Any comprehensive legislation by
India in the future over the Exclusive Economic Zone and the continental shelf,
would also be applicable to these areas even beyond the EEZ, once we complete
the obligations of delineation.
Under this project, it is proposed to carry out the following tasks in
1997-98:
* Chartering the vessel
* Procurement of equipment
* Utilisation of existing facilities & ships available to NHO, GSI &
DOD towards simultaneous Pilot Survey.
Financial Requirements : Rs.1.00 crore.
D. Marine Non-living Resources:
The preparatory work on the following aspects are proposed to be taken
up during 1997-98, under this project.
* Identification of the nature, chemistry and frequency of
hydrothermal discharges in the Andaman back area basin, relate
it to the ongoing seafloor volcanism and spreading and to develop
a model for hydrothermal processes and metallogenis.
* Generating high resolution climate change markers in the
sediments of the Bay of Bengal and develop a dynamic model of
sedimentary accumulation during glacial and inter-glacial
periods.
Financial Requirements : Rs.0.05 crore.
E. Assessment of Marine Living Resources:
With a view to have a realistic and reliable information on the potential
marine living resources in the Indian EEZ for sustainable development and
management and to augment the sea food production and thereby the income
of the coastal fishing community and the fishing industry, it is proposed to take
up a concerted programme for assessment of marine living resources beyond
50m depth in the Indian EEZ and correlate fish abundance with ecological
aspects. The activities envisaged for 1997-98 include :
* Compilation of available information on marine living resources,
their distribution and their inter-relationship with oceangraphic
parameters.
* Development of a systematic and standard methodology for
carrying out resoruces survey in the Indian EEZ.
* Upgradation/augmentation of on-board and on-shore facilities
with Sagar Sampada Cell, FSI and educational institutions.
Financial Requirements : Rs.0.05 crore.

CHAPTER V
Appraisal of Performance of Major Programmes/Projects |
Antarctic Research Programme:
The Antarctic Research programme which was initiated on a modest
scale in 1981 has since taken shape into a major national programme that has
a distinct multi-institutional and multi-disciplinary approach. Sixteen scientific
expeditions have been launched on a regular annual basis which has carried
out research work in the thrust areas of polar sciences. Till date, more than 45
national institutions have participated as scientific and logistic components of
the expedition thereby putting about 1200 Indians to the icy continent.
The first Indian station, Dakshin Gangotri which was established on the
ice-shelf in 1984 has since outlived its life and has been replaced by a modern
and indigenously built station `Maitri' which was established in the
Schirmacher Oasis in 1988. Maitri is equipped to provide comfortable living
facilities for 25 persons on a year round basis and has several laboratories to
carry out research in the frontier areas of Antarctic Science. So far, ten
technical reports have been published and two reports are presently under
preparation. Approximately, 300 scientific papers have been published in
various national and international journals of repute.
By virtue of our sustained scientific interest in Antarctica, India has
acquired Consultative Status in the Antarctic Treaty System. She is also a
member of the various international bodies affiliated to the Antarctic Treaty
System. India has been able to decisively influence the outcome of the
negotiations leading to the adoption of the protocol on Environmental
protection to the Antarctic Treaty in 1991, which has since been ratified by
India in April 1996.
The Department constantly evolves scientific programmes, which are
based on national priorities and can contribute to global issues. India's long
term scientific strategy in Antarctic has been judiciously framed by the
Department with a clear cut focus on three basic and mutually dependent
factors namely, science, logistics and economics. Over the years, a distinct
impetus on scientific objectives has resulted in an increase in the scientific
team component over the logistic team.
In brief, the benefits of the Antarctica scientific research to India are:
* Studies of Antarctic meteorology with the aim to build a
climatological data set for application in the prediction and
forecast of the Indian monsoons.
* Studies on ozone hole and other trace gases to understand its
influence over the climatic pattern of the Southern Indian Ocean.
* Studies on auroral phenomenon and geo-magnetic storms have
yielded valuable insights to solar terrestrial physics of the outer
space.
* Geological mapping of hitherto unmapped areas of Schirmacher
Oasis and Wolhthat mountains has helped to understand the
geological evolution of this area and its co-relation in the
reconstruction of the Gondwana land.
* Studies on human adaptations in cold and extreme conditions
and this application to the frontier regions of the country.
* Identification of Antarctic microbes and its application for human
and organic waste degradation in cold regions of Himalayas.
* Technology transfer on a commercial basis as a spin-off of the
SODAR instrument developed in Antarctica for studying inland
environmental pollution.
* Research and development in cold temperature technology in
designing prototype toilet incinerators, generators and low
temperature structures used in Antarctica has been deployed in
colder regions of the country.
* Availability of trained manpower pool to work in extreme cold,
harsh and isolated conditions have been generated from the
expeditions.
* The Indian Navy and Air Force by virtue of their participation in
the expeditions have gained professional expertise of the highest
order in snow-ice navigation under adverse climatic conditions.
Polymetallic Nodules Programme:
The Polymetallic Nodules Programme envisaged eventual exploitation of
the nodules from the allotted mine site in the Central Indian Ocean Basin.
As commercial mining of nodules according to international forecasts
may not be feasible till 2010, development of technologies for mining from the
deep ocean may be viewed as contribution to a long term objective. The
Department appointed two committees headed by Shri M. Gopalkrishna,
Additional Secretary and Shri B.K. Rao, Ex-Secretary, Ministry of Mines to
suggest alternative uses of technologies for intermediate applications. The
entire mining programme has been reoriented on the recommendation of these
committees.
An upgraded version of Remotely Operated Vehicle (ROV) has been
designed, developed and tested in shallow depth of 5 metres by Central
Mechanical Engineering Research Institute (CMERI), Durgapur. A 2nd
generation ROV is being designed. Simultaneously at the shallow water sand
mining system off Chavara coast, Kerala, Environmental Impact Assessment
(EIA) study was commissioned. Pre- disturbance baseline data has been
collected for one year off Chavara as a part of EIA study.
The Survey and Exploration endeavour is aimed at firmly establishing
the resource potential on the basis of progressive closer grids sampling, spot
photographs. Topography of the pioneer area has been completely covered by
hydrosweep. The abundance pattern vis-a-vis the geomorphology is
established along with upgradation of the resource evaluation techniques on
the basis of one lakh photographs obtained from the mine site. Three moored
systems have been deployed in the pioneer area which continue to obtain
continuous time series oceanographic data. The analysis of the data will reveal
the environmental condition at various depths over a period of time in the
pioneer area of the Central Indian Ocean. A report recommending additional
10% relinquishment of the pioneer area has been prepared.
For the extraction of metals from the nodules, three metallurgical routes
were pursued at National Metallurgical Laboratory (NML), Jamshedpur,
Regional Research Laboratory (RRL), Bhubaneswar and Hindustan Zinc Ltd
(HZL), Udaipur. Pilot plant campaigns of 100 kg per day capacity are continued
at RRL and NML for optimising the process parameters for recoveries of Copper,
Nickel and Cobalt. At HZL bath scale experiments are conducted for firming up
the process package.
Marine Satellite Information Service (MARSIS):
The major achievements of this programme so far include:
* Operational generation and dissemination of SST and PFZ
advisories. Extensive validation studies of the PFZ advisories have
confirmed its utility in reducing the search time by fishing boats
and also in getting better catch per unit effort. This data product
has been well accepted by both the traditional and mechanised
fishing sectors. However, the Department plans to further refine
the PFZ by incorporating other parameters such as chlorophyll
data which could not so far be achieved due to non-availability of
ocean colour data from satellites. It was originally planned to get
this data from the sea WiFs, on-board the American Satellite "sea
star". However, the launch of this satellite has been postponed
repeatedly and the satellite is yet to be launched.
* The coral reefs of the entire country have been mapped and
codified. These maps are useful in the scientific management of
the fragile coral ecosystem.
* Coastal wet-land maps and for the Shore-line change maps of
entire country have been prepared. These maps indicate
mangroves, aqua- culture sites, coastal erosion, accretion which
are useful in coastal zone management.
* Suspended sediment load maps developed through the MARSIS
programme can be effectively used by the port authorities, State
Governments and researches for various applications.
* The programme has also succeeded in demonstrating on a pilot
basis the capability for retrieval of other parameters such as
winds ,wave, currents, Mixed Layer Depth, Heat budget of the
oceans etc. from satellite data. If satellite data is available on a
regular basis, these parameters can be made operationally
available.
National Ocean Information System (NOIS):
This programme has the productive and purposeful use of the
information generated by R&D institutes through a network of data centres by
having an intellectual and material connectivity with each other. It shares and
exchanges data and information with expert institutes engaged in R&D
activities in ocean sector. So far 13 institutes specialised in specific areas of
activity located in different parts of India have been identified to accomplish the
objectives of collection, validation, collation, storage and dissemination of
information for its productive use.
Coastal Ocean Monitoring & Prediction System (COMAPS):
Infrastructural facilities to all the participating institutions have been
fully strengthened with sophisticated equipment to achieve the activities
stipulated for this programme.
The programme has for the first time identified areas of no, low,
moderate and high concentrations of pollutants in the seas around India. This
is expected to the State Pollution Control Boards to take control / remedial
measures particularly in areas of moderate and high concentration of
pollutants. The data and information collected have also been useful in taking
decisions on location of industries and encouraging human settlements.
Coastal Research Vessels:
Two Coastal Research, viz., Sagar Paschmi and Sagar Purvi
commissioned during 1996-97, will facilitate collection of samples at all
desired locations along the coastline and onboard analysis of several physico-
chemical and biological parameters stipulated under the COMAPS programme.
National Institute Of Ocean Technology (NIOT):
The major objective of NIOT is to initiate and develop new technologies
for harnessing ocean resources. As the ocean field is quite large, the work of
NIOT is mandated to be carried out under four specific missions as mentioned
in the earlier chapter. The major achievements of NIOT so far have been
development of a new generation power module required in the wave energy
project. Through intensive design and modelling an improved air turbine with a
variable speed induction generator has been designed and fabricated. The new
power module has been installed in the Wave energy plant and its performance
is being studied.
Exploration of Living and Non-living Resources:
FORV Sagar Sampada has so far completed 150 cruises. These
cruises were undertaken for physical, chemical and biological
oceanography, resource surveys, harvest and post-harvest technologies,
productivity studies, biogeochemical processes, pollution monitoring etc.
The vessel participated in a 75 day successful Krill Assessment
Cruise during December, 1995 to March, 1996 for studying the potential of
krill in the Indian Ocean Area of Antarctic Waters. The vessel covered 33
sampling stations making 16 trial hauls in the southern ocean for a period
of 22 days and conducted a number of experiments, collected data on
distribution and abundance of krill and other living resources.
ORV Sagar Kanya has so far participated in over 120 cruises in the
Indian EEZ and contiguous high seas for assessment of the non-living
resources, Oceanographic studies, Joint Global Flux Studies etc.
Marine Research and Manpower Development:
Under the basic research programme 42 projects for promotion of basic
research in ocean sciences were implemented. These projects have provided
interesting results on the history of the sedimentation process, tectonic events
including Himalayan drift; have given an insight into the physical
oceanographic phenomena like upwelling and the Heat budget; have provided
clues for development of potential drugs and chemicals from the marine
organisms, etc.. The studies on coastal pollution have indicated the areas of
heavy metal pollution. Similarly, the studies on coastal dynamics as well as
circulation and sedimentation processes have indicated the need and extent
for/of dredging operation in the ports and harbours. Over 65 scientific papers
on various aspects of Ocean Science & Technology were published in standard
journals. Over 100 fellowships were awarded for undertaking research
activities in the field of ocean sciences and technology. The opening of
specialised Centres of Excellence has also given a boost to the R&D efforts in
Ocean Sciences in specific areas, such as Air-Sea interaction, Coastal Zone
Management, Antarctic Research, Polymetallic Nodules, Coastal Aquaculture,
etc. These programmes have also helped the participating institutes in
augmenting the manpower resources, through capacity building in ocean
sciences and technology.
International Obligation /Cooperation:
Consequent on coming into force of UNCLOS, India is entitled to
delineate the continental margin beyond the EEZ of 200 nautical miles, which
can extend our sovereign rights over the natural resources of the continental
margin.
Drugs from Sea:
The National Project on Development of Potential Drugs from the Ocean
has led to identification of 17 potential organisms having properties as anti-
fertility, anti-microbial, anti-viral, anti-diabetic, anti-malarial, anti-
hypertensive, anti-inflammatory, anti-anxiolytic, anti-amoebic and larvicidal
agents. Out of these, five organisms which showed potent activity as anti-
diabetic, anti-viral, anti-amoebic, anti-anxiety and larvicidal agents, have been
identified for developing atleast two herbal drugs in the next few years.
Marine Instrumentation :
The communication facilities created in nine places in the four
southern states and South Goa have benefited over 850 fishermen families,
and demonstrated the usefulness of the communication system to the safety of
fisherfolk. This has paved the way for extending such facilities to the fishermen
living in the other coastal states and the Island groups. The extended phase of
the project will provide such facilities at ten more places benefiting over
1350 fishermen families.
Indigenisation of the technology for integration of Global Positioning
System navigator and fish finder, under a pilot project, has enthused the
private firms to venture into production of such units for the benefit of small-
scale fishermen as they will be useful to the small-scale fisherfolk in locating
the position of the fishing vessel at sea, for ensuring their safety and locating
the fishing shoals, improving their livelihood, socio-economic status and
enhancing their income.
Island Development Programme:
The Shrimp Culture Project taken up in A & N Islands has
demonstrated the economic viability of scientific methods of shrimp farming in
acid sulphate soil. The A & N Centre for Ocean Development (ANCOD) has
provided the basic requirement to the Islanders for undertaking the following
activities :
* Oceanographic studies.
* Coastal Ocean Monitoring and Prediction System (COMAPS)
programme of the DOD.
* Demonstration of mixed culture of fish species.
* Rejuvenation of coral reefs in A&N Island.
* Setting up of two state of the art tide gauge stations at Port Blair
and at Southern group of Islands for continuous monitoring of sea
level rise.
