Based on the data collected by the research vessels, Discovery (UK), Vityaz (USSR), Anton Bruun (USA), and INS Kistna (India), during the International Indian Ocean Expedition Programme (1960-65), season-wise concentrations of the available phosphate in the upper 100 m in the different regions of the northern Indian Ocean were reported. Peripheral regions both of the Arabian Sea and the Bay of Bengal showed higher concentrations, while the central and equatorial regions remained relatively poorer during the NE and pre-monsoon seasons. During the SW monsoon, the concentrations increased in almost all the regions, and this rising trend was maintained during months immediately following it. Maximum concentrations (5.3 g/m2) were observed in waters off the Oman and Iran coasts and slightly less in waters off Pakistan and west coast of India during the post-monsoon months. The computed phosphate data of the respective regions when compared with the primary productivity and the plankton biomass data showed no direct relationship with the former but agreed more closely with the latter, though qualitatively if not quantitatively. In general, the pattern of distribution conforms broadly with that of the highly productive areas of the northern Indian Ocean. |
