In the present era of climatic change research, the role of various physico-chemical parameter of coastal ecosystem has become
the focal point of major scientific investigation because of the fact that the CO
plays a leading role in directing global climate
patterns on one hand, and on the other, during the air-sea gas exchange, surface seawater uptake of the CO
is reported to be
causing ocean acidification. Since in the determination of climatic change through ocean system in respect of carbon dioxide,
it is important to study the thermodynamics equilibrium of the gaseous carbon dioxide [CO
(g)] and CO
and that are related
by Henry?s law where the temperature and salinity dependent solubility coefficient of CO
in seawater, the present piece of
investigation was carried out under two different seawater systems of India to assist Indian climate science research.
DIU (Union Territory of India) situated at 20o 42? N, 71o 01? E facing Arabian Sea and Visakhapatnam (State of Andhra
Pradesh) situated at 17o41? N, 83o17? E facing Bay of Bengal were selected for having two different geographical and socio-
economic situations. In both the project regions 5 different locations were chosen to carry out the investigation on the spot,
specially for air temperature measurement and sampling of water and sediment and their subsequent analyses in the laboratory
with all due precautionary measures.
It is evident that
H of the surface seawater was found to be in increase in trend in DIU during November-February (8.91
0.5 to 8.47
0.5 mean of 6 years )and decrease in trend during April-June (8.01
0.5 to 7.95
0.4). In Visakhapatnam, the pH
value of the surface seawater was found (7.91
0.5 to 7.16
0.5 mean of 6 years) to be significantly lesser than that of found in DIU
during the same period both in surface sea water and sediment (taken 5 ft overlying seawater condition in all the locations).
NaCl salinity-temperature (surface seawater or sediment) relationship as established for long by various earlier workers in most
of the cases both in DIU and Visakhapatnam were found to be not maintainable.
Anupam Ghosh earned two Bachelor Degrees in Biological Sciences (B.Sc.-Bio) and Law (LL.B.), a Master Degree in Agriculture (M. Sc.-Ag), a
Doctorate Degree (Ph.D.) in Plant Physiology related to Agro-Environmental Studies on Pesticides from the University of Calcutta, and also earned
three Graduate (Master level) Certificates from Bermuda Biological Station for Research (Lexington Avenue, New York, U.S.A.) in Marine Science
& related resource management that include : (1) Analysis of Marine Pollution; (2) Oil Spill Contingency Planning ;and (3) Biogeochemical Cycling
Processes in Coastal Carbonate System - all in and with the North Atlantic Ocean Systems. Dr. Ghosh had proceeded his academic and research
interests in Oceanography primarily under the renowned Scientist and Philosopher, Dr. James Newton Butler, Ex-Gordon McKay Professor of
Applied Chemistry, Harvard University, U.S.A. Dr. Ghosh was awarded ?Young Scientist? in Agricultural Science in 1981 from West Bengal for his
outstanding work with Insecticide, fungicide and weedicide in Rice & Wheat in West Bengal, jointly by the Indian Science Congress Association and
Department of Science & Technology, Govt. of India. Dr. Ghosh also has advised Prime Minister of India, Mr. Chandrasekhar Singh, for formation of
the ?Task Force? combating Oil Spill pollution problem during Gulf War in the year 1991.
