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 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.
Millions of tiny, single-celled plant-like organisms ring the Falkland Islands in this photo-like image taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on January 13, 2008. These organisms, called phytoplankton, reflect light, coloring the ocean with whimsical swirls of blue and green.
