Spatial and temporal variability of chlorophyll-a concentration in the South Eastern Arabian Sea (SEAS)

Satellite remote sensing is being effectively used in monitoring the ocean surface. Among the ocean observing satellite sensors, ocean colour sensors make use of visible band of electromagnetic spectrum (shorter wavelength). The use of shorter wavelength ensures fine spatial resolution of these parameters to depict oceanographic characteristics of any region having significant spatio-temporal variability. The Southeastern Arabian Sea (SEAS; encompassing between 70.5-77.5oE longitude and 8-15oN latitude) is such an area showing very significant spatio-temporal oceanographic and atmospheric variability due to the seasonally reversing surface winds and currents (Shankar et al., 2002; Shetye et al., 1990
