The phenomenon of wind-driven upwelling occurs when high coastal winds blow over the ocean surface, pushing warm surface waters offshore and allowing cooler, more nutrient rich water from below to rise up to the surface. This process creates a signature in sea surface temperature (SST) data where cooler water can be seen surrounded by warmer water. Such upwelling zones are visible in this SST data acquired by the NOAA GOES and POES satellites on March 9, 2011Ensino Médio::GeografiaEducação Superior::Ciências Exatas e da Terra::Oceanografia
