A monthly monitoring programme conducted at two different sampling stations in and around the mangrove ecosystem of deltaic Sundarbans, India during January, 2000 to December, 2001 showed maximum phytopigment concentrations during premonsoon and minimum during monsoon seasons. Physico-chemical variables like surface water temperature, salinity, pH, dissolved oxygen, extinction coefficient and nutrients were also analysed simultaneously during the monitoring period The concentrations of chlorophyll a, b andc exhibited significant positive correlations with surface water salinity and pH, but with nutrients like nitrate, phosphate and silicate, significant negative relationships were observed in both the sampling stations. The low phytopigment concentrations at station I may be related to severe anthropogenic stress around this zone.

Abstract


A monthly monitoring programme conducted at two different sampling stations in and around the mangrove ecosystem of deltaic Sundarbans, India during January, 2000 to December, 2001 showed maximum phytopigment concentrations during premonsoon and minimum during monsoon seasons. Physico-chemical variables like surface water temperature, salinity, pH, dissolved oxygen, extinction coefficient and nutrients were also analysed simultaneously during the monitoring period The concentrations of chlorophyll a, b andc exhibited significant positive correlations with surface water salinity and pH, but with nutrients like nitrate, phosphate and silicate, significant negative relationships were observed in both the sampling stations. The low phytopigment concentrations at station I may be related to severe anthropogenic stress around this zone.
