Abstract

The seasonal changes in the temperature, salinity and plankton volume
at Port Blair, Andamans, during the period 1964 to 1970 have been investigated
and the changes correlated with the meteorological conditions of the locality.
The atmospheric temperature exhibited a clear double oscillation in a year, the
maxima occurring in April and November. The range of fluctuation was generally
less than 10°C. The surface temperature closely followed the atmospheric
temperature and exhibited a clear double oscillation. The surface temperature
was invariably lower than the atmospheric temperature. The temperature of
the surface water steadily increased from January to April registering a sharp
fall in May due to the onset of the south-west monsoon. The surface salinity
increased steadily from January to April registering a fall in May which coincided
with the onset of the monsoon. Higher values were restored during the
post-monsoon period. The surface water was fairly rich in plankton during the
colder months. An inverse relationship was noticed between the abundance of
plankton and temperature/salinity.
