Spatial Distribution of Net Phytoplankton Along Thannirubavi Coast, Dakshina Kannada, Karnataka

摘要

The net phytoplankton distribution in relation to various depths along Thannirubavi, Dakshina Kannada revealed that the hydrographical parameters like sea surface temperature, pH, salinity and dissolved oxygen exhibited a increasing trend from shallower depths to deeper parts. Whereas, other hydrographical parameters exhibited a mixed variation. The phytoplankton cell numbers are high at shallower depths and diatoms formed the bulk of the phytoplankton population. Diversity indices exhibited a narrowvariation with space and it is clear that net phytoplankton distribution is dependent of nutrient load and depth of the water.
