NASA's Aquarius Instrument Has Been Measuring Changes in Salinity

Caption

NASA's Aquarius instrument has been orbiting the Earth for a year, measuring changes in salinity, or salt concentration, in the surface of the oceans. The Aquarius team released last September this first global map of ocean saltiness, a composite of the first two and a half weeks of data since the instrument became operational on Aug. 25.
