Surface circulation over the shelf off the east coast of India during the south west monsoon

Abstract

From the hydrographic data collected on board R V Gaveshani in the Western Bay of Bengal during August-September 1978, fields of temperature, salinity have been constructed and the probable flow regime has been deduced. The studies indicate strong upwelling in the southern regions off the East Coast of India. Vertical temperature and salinity structures north of Visakhapatnam show a predominant estuarine character and upwelling is not evident. In the northern regions, the flow is directed south and is consonant with that derived from wind stress curl distribution
