Abstract
A phytoplankton bloom dominated by Chaetoceros spp. was detected in the Arabian Sea off Cochin coast during May 2009 coinciding the onset of Southwest monsoon with an average chlorophyll a concentration of 8.42 mg m<sup>-3</sup> at four stations (A,C,D&E) of total 7 stations studied in coastal waters situated between latitudes 9degree54'-10 degree 02' N and longitudes 76 degree05'-76degree12'E. All the stations were resampled after seven days and found that the average chlorophyll a concentration at the bloom stations has decreased to 2.91 mg m<sup>-3</sup>. The inherent optical properties (chlorophyll a) specific phytoplankton absort
