NASA's Aquarius observatory, launched in June 2011, produced this map of the salinity of Earth's oceans. Technologies on board include an optical camera, thermal camera, microwave radiometer, and other sensors. The data collected will be used to assess global rainfall, ocean currents, and climate. The image shows, for example, higher salinity in the Atlantic Ocean than in the Pacific and Indian oceans. Credit: NASA/GSFC/JPL-Caltech
