Studies on upwelling at the turn of this century

Abstract

Upwelling in the waters around India and the transformation of physical properties of the neritic waters thereof with a stress on thermal front and the potential utility for fish production in the sea are described. The necessity of obtaining the snapshot pictures with high grade resolution of locations and Intensities of upwellings and thermal fronts is stressed for effective management of marine fisheries. The only means of fulfilling this objective is by switching over the observations from the time-consuming ship-borne observations to satellite produced imagery system Therefore, by the turn of this century, the software suitable for localised conditions should be developed and perfected so that the present day sea truth data collection system by ships would be used only as occasional checking points.
