It’s impressive when a microscopic organism is visible from space, but that’s a regular occurrence for phytoplankton, the tiny marine algae that feed much of the ocean. In this video from NASA Earth Observatory, we travel around the globe, observing phytoplankton blooms and learning about the ecosystems they feed — or destroy.
Note that many of these satellite images have been color-enhanced to bring out the swirls and eddies of each bloom. The colors are enhanced but the patterns are real. (Image and video credit: NASA Earth Observatory)
