APLICATIONS OF ENVISAT DATA IN THE SOUTH OF CHILE: MONITORING ALGAL BLOOMS AND OTHER COASTAL OCEAN FEATURES USING MERIS AND AATSR IMAGERY

Phytoplankton blooms have been monitored from April 2003 to August 2004, between latitudes 41°S and 45°S, in the region of Los Lagos in Chile, using MERIS and AATSR data from ENVISAT and from in situ oceanographic measurements. Apparently no other applications of remote sensing to mo...
