Phytoplankton off the Coast of Portugal
A large phytoplankton bloom off of the coast of Portugal can be seen in this
true-color image taken on April 23, 2002, by the Moderate-resolution Imaging
Spectroradiometer (MODIS) aboard NASA’s Terra satellite. The bloom is roughly
half the size of Portugal and forms a bluish-green cloud in the water. The red
spots in northwest Spain denote what are likely small agricultural fires.
