%K remote sensing, chlorophyll concentration, sea surface temperature, Ubatuba.
%X The phytoplankton is the basis of the marine food chain and contains the pigment chlorophyll which is used for photosynthesis. During this process, the sunlight is used as an energy source to fuse water molecules and carbon dioxide into carbohydrates. The pigment chlorophyll absorbs the blue and green wavelengths of sunlight, whereas water scatters them. A simple satellite measurement of the blue-green light ratio leaving the ocean is a way to quantify the chlorophyll concentration, and the phytoplankton abundance in the study area. Ocean color remote sensing is a powerful method to complement in situ studies. This scientific work analyses the phytoplankton biomass variability based on environmental variables in Ubatuba, a coastal zone of the state of Sao Paulo and compare it with MODIS/AQUA satellite estimates. The in situ time-series is a Brazilian contribution of the Oceanographic Institute of the University of Sao Paulo and the National Institute of Space Research to the Antares net of observations. This work consider the samples collected from December 2004 to January 2006. The in situ chlorophyll and sea surface temperature data were compared to the satellite estimates, showing a significant statistical correlation. Meteorological and climate variables were also analyzed during the same period. A multiple regression analysis showed linear relation between the water column integrated chlorophyll and the euphotic depth, sea surface temperature and sea surface chlorophyll concentration.
