Swirling green clouds of phytoplankton bloom in the North Sea, the Skagerrak, and the Kattegat straits between Norway and Denmark in this summertime image acquired on May 23, 2004, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Save for the highest points, Norway and Denmark glow with rich green vegetation. The blooms of phytoplankton in the water, like land-based vegetation, thrive off of sunlight, which they use to convert nutrients in the water into energy. These phytoplankton blooms tend to thrive in cold, deep water, and are fairly common at these latitudes.
