Sargassum seaweed in the Gulf of Mexico has been detected from space for the first time using optical radiance data from the Medium Resolution Imaging Spectrometer (MERIS) aboard Envisat. The ability to monitor Sargassum globally will allow researchers to understand better the primary productivity of the ocean and better predict climate change.
