Description 1513-1518
Phytoplankton samples of north-eastern Arabian Sea were collected during
ocean colour satellite validation cruises from 2003-2007. Phytoplankton
community organization and distribution was analyzed using various diversity
indices like Shannon Diversity Index, Simpson Diversity Index, Margalef
Diversity Index, McIntosh Diversity Index, Pielou Evenness Index and dominance
index. Results showed that Navicula,
Thalasiothrix and Rhizosolenia
were most abundant among the diatoms. Trichodesmium,
a cyanobacteria, dominated the shallow coastal waters. Resultant indices were
correlated with phytoplankton cell counts and it was found that Shannons index better represents the diversity than other
indices. Cell counts were also correlated with in situ chlorophyll-a values, which showed that this correlation
does not stand good for the bloom conditions.
