Description 1718-1731
A study was carried out in the coastal waters of
Kalpakkam, southeast coast of India, in order to find out the prevalence of
different water masses in a spatio-temporal scale. This region of southwestern
Bay of Bengal is influenced by both southwest and northeast monsoon. However,
in absence of any major perennial freshwater input into the coastal water, the
water mass characteristics in this region mainly depends upon the coastal
current pattern. Statistical analysis showed two temporally distinct water
mass; one during the monsoon period and the other during the pre- &
post-monsoon periods. Cluster analysis also depicted existence of a well marked
spatial heterogeneity in the study area. 
Five principal components developed showed distinct environmental states
of coastal waters such as nitrogen enrichment, phytoplankton growth, phosphate
enrichment, low dissolved oxygen & high temperature condition and nitrite
enrichment which might have existed at this location on a temporal scale.
