The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these natural-color images of a deep-ocean eddy on December 26, 2011. The top close-up shows the vortex structure of the eddy, traced in light blue by plankton blooming in the 150-kilometer wide swirl. The lower, wider view shows the bloom and eddy in context, about 800 kilometers south of South Africa. “Eddies are the internal weather of the sea,” says Dennis McGillicuddy, an oceanographer at the Woods Hole Oceanographic Institution.
