Description 445-448
Data
collected from surf waters of Mangalore revealed the time scale variation of
hydrographical parameters and phytoplankton community. Salinity and plant
nutrients specially nitrate and silicate exhibited a conspicuous fluctuation in
relation to intensity of precipitation. Surf water was characterized with much
higher levels of limiting nutrients than the Redfield ratio. Diatoms dominated numerically among phytoplankton in
the surf waters followed by dinoflagellates and blue green algae. Lower
salinity associated with high load of nutrients favored the growth of bloom
forming centric types of diatoms. While diverse forms of diatoms,
dinoflagellates and blue green algae occurred with increasing salinity in surf
waters. Shannon’s species diversity varied from 0.049 to 2.125 and Shannon’s
evenness index varied from 0.020 to 0.735. Diversity indices indicated gradual
increase in diversity and evenness values in relation to variation of salinity
and nutrients
