When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on December 2, 2015, the waters northeast of the Falkland Islands (Malvinas in Spanish) were awash with color. The swirling greens and blues are densely concentrated phytoplankton growing on the surface of the ocean. These microscopic, plant-like organisms thrive in the cool, nutrient-rich waters off the coast of southern Argentina.
