Aquarius/SAC-D

Description:
Changes in sea surface salinity have large-scale effects on Earth’s water cycle and ocean circulation. Before now, scientists had studied these changes using measurements collected by ships and buoys out at sea. Fortunately, for the first time ever, NASA’s Aquarius/SAC-D satellite will provide space-based, global sea surface salinity measurements. Surface salinity data from Aquarius/SAC-D will give scientist a key to better understanding how ocean circulation is tied to global climate.
