Distribution of chlorophyll 'a' and 'b' in the eastern Arabian Sea (west coast of India) in relation to nutrients during post monsoon

Abstract

The distribution of chlorophyll 'a' and 'b' in the Arabian Sea along the west coast of India from Cape Comorin to Veraval in the 40-200rn depth contour, in a single cruise of FORV Sagar Sampada (Cruise no. 177) was studied, covering 58 stations duringng the post monsoon period October-November, 1999. Data on nitrates and phosphates were also collected along with chlorophylls. The results indicated that the coastal waters along the south west coast of Inaia are more productive than the waters along the north west coast during the post monsoon period. Earlier observations on chlorophylls and nutrients from eastern Arabian Sea are briefly discussed.
