Description A study of the sea water temperature and salinity of the coastal waters along the southwest coast
of India between Cape Comorin and Ratnagiri based on observations made along 6 sections for a period
of 8 years is made use of for the study. The variations in the monthly mean sea surface temperature
and salinity, the position of the therraocline and depth of salinity maxima were studied. Vertical
time series sections were used to compare the variations noticed in the vertical oscillation of various
isotherms in space and time. An attempt is made to identify the isotherm which exhibits maximum
vertical oscillation. The net vertical movement of the water masses, was estimated based on the
vertical oscillation of selected isotherm. Possible existence of convergence zones in the area under
study was established with the help of horizontal salinity distribution maps. An attempt is also made
to examine possible correlations of sea water temperature and salinity with the occurrence of oilsardine,
mackerel and whitebait in the area under study.
