Circulation and Water Characteristics on Isanosteric surfaces in the Northern Arabian Sea during February-April

Abstract

Distribution of water characteristics and circulation were studied on 260, 160, 140, 120 and 80 cl/t surfaces using isanosteric analysis and geostrophic computation The circulation pattern consisted of several eddies and meanders The most prominent anticyclonic eddy was located around 24 degrees N and 64 degrees E Deepest mixed layer occurred in this region Appreciably deep vertical extension of the eddies was a notable feature The eddy circulation is proposed to be due to the influence of uneven bottom topography Persian Gulf water appeared to flow into the Arabian Sea through the northern part of the Gulf of Oman Distribution of properties was marked by several pockets of high and low values
