Estimation of chlorophyll distributions obtained from satellite images (Nimbus-7/CZCS) in the Antarctic Ocean

Previous studies have established that ocean color information from Nimbus-7/CZCS{Coastal Zone Color Scanner) could be related to distribution of phytoplankton pigment (Chlorophyll-a + pheopigments) concentrations. CZCS data from polar regions have been utilized only a limited number because of many problems as cloud cover, large solar zenith angles, bio-optical algorithm and other logistic constraints. This papar discusses the characterization of phytoplankton pigment concentrations.
