Distribution of particulate organic carbon in the central Bay of Bengal

Abstract

Particulate organic carbon (POC) was measured for 77 water samples collected over a 3000 in water column along 88 degrees E in the central Bay of Bental. The POC values varied from 80 to 895 mu g per litre at the surface and 171 to 261d mu g per litre at 2000 m. The POC decreased with increasing water depth at all the stations. Deep water concentrations of POC were higher than those reported from other oceanic waters. Distribution of POC was not influenced by water masses. The POC was not significantly correlated with chlorophylls
