| Description |
Nitrogen concentration and its isotopic composition in surface suspended matter have been measured at 24 different locations during the post-monsoon season in the Bay of Bengal. In general, the stable nitrogen isotopic composition of surface particulate organic nitrogen (PON) in the Bay of Bengal appears to be a mixture of particulate matter from the continent and marine phytoplankton, the latter having inherited the isotopic composition of deeper nitrate. Higher δ15 N values of surface PON in open ocean locations could be due to the supply of nitrate with higher δ15 N values. However, offshore locations have been diluted by the continental influence leading to low δ15 N values in PON.
