Aquarius Yields NASA’s First Global Map of Ocean Salinity

PASADENA, Calif. – NASA’s new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission’s anticipated discoveries.

Aquarius, which is aboard the Aquarius/SAC-D (Satélite de Aplicaciones Científicas) observatory, is making NASA’s first space observations of ocean surface salinity variations — a key component of Earth’s climate. Salinity changes are linked to the cycling of freshwater around the planet and influence ocean circulation. (more…)

NASA Mission Will Observe Earth’s Salty Seas

PASADENA, Calif. – Final preparations are under way for the June 9 launch of the international Aquarius/SAC-D observatory. The mission’s primary instrument, Aquarius, will study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity.

Engineers at Vandenberg Air Force Base in California are performing final tests before mating Aquarius/SAC-D to its Delta II rocket. The mission is a collaboration between NASA and Argentina’s space agency, Comision Nacional de Actividades Espaciales (CONAE), with participation from Brazil, Canada, France and Italy. SAC stands for Satelite de Applicaciones Cientificas. Aquarius was built by NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the agency’s Goddard Space Flight Center in Greenbelt, Md.
