Abstract:
The present study is aimed at observing the variations, in
space and time, of see of the important hydrographic parameters such
as sea water temperature, salinity and Resolved oxygen within the
coastal waters along the south-west coast of Indiametween Ratnagiri
(17°OO*N,73°20'E) and cape comorin ( 8°10'N,77°30*E). Specific data
relating to the process of upwelling and sinking was collected mainly
to evaluate the extent and intensity of the vertical mixing processes
active in the area under study. The study also attempted possible correlations between the observed parameters and the occurrence and migrations of some of the major pelagic fishery resources such as sardine,mackerel and anchovy in the area under study

Abstract:
In the present study, the main emphasis was to find out it seasonal and ecosystem specific variations of calcium magnesium, phosphorus, copper and zinc in the water and the
sediment has any role to play in altering the concentration of these elements in different tissues of intermoult p.indicus as evidenced by the seasonal studies in the grow out
and the marine ecosystems

Abstract:
Of the several physical processes occurring in the sea, vertical motions have special significance
because of their marked effects on the oceanic environment. upwelling is the process in the sea
whereby subsurface layers move up towards the surface. The reverse process of surface water sinking to subsurface depths is called sinking. Upwelling is a very conspicuous feature along the west coasts of continents and equatorial regions, though upwelling also occurs along certain east coasts of continents and other regions, The Thesis is an outcome of some investigations
carried out by the author on upwelling and sinking off the west and east coasts of India. The aim of the study is to find out the actual period and duration of upwelling and sinking, their driving mechanism, various associated features and the factors that affect these processes. It is achieved by analysing the temperature and density fields off the west and east coasts of India, and further conclusions are drawn from the divergence field of surface currents, wind stress and sea level variations.
