Portrait allows scientists to monitor global plant life for the first time.
SeaWiFS gives scientists a new tool to measure the effects of El Nino and global warming, and also do environmental monitoring, such as, tracking oil spills and cholera outbreaks. The global ocean color images from SeaWiFS will be used by researchers to study how human-induced and natural events affect the global biosphere. On land, areas with little or no vegetation are colored brown and heavily vegetated are dark green. This is NOT a finished production and contains no narration.
