a Monthly variation of phytoplankton standing crop (cells/m3) in Sundarbans estuary. Each value represents mean of 180 samples. b Monthly variation of phytoplankton abundance (x 105cells/L) in Sundarban estuary. Each value represents mean of 180 samples. c Monthly variation of bacterial abundance (cells/ ml) in Sundarbans estuary. Each value represent mean of 180 samples.
