Hydrography of the waters along the Gujarat Coast during the summer period of the year 1963

Abstract

The hydrographic features of the waters along the Gujarat Coast during the summer period of 1963 are presented and discussed. During this period the waters were mostly isothermal within the continental shelf and a thermocline was perceptible only outside the shelf. Maximum salinity was observed in the region off Porbandar which again was the region of minimum temperature and maximum dissolved oxygen content. A southward increase in temperature was associated with a southward decrease in salinity. The sinking and spreading of high saline waters from the Gulf of Aden and Persian Gulf were perceptible in investigational area.
