Aquarius to Measure Oceans' Salinity

Scheduled to launch June 9th, Aquarius/SAC-D, an international spacecraft mission, will make the agency's first space-based global measurements of salinity, or concentration of salt, at the surface of the world's oceans. Scientists from Argentina, Brazil, Canada, France and Italy were at NASA Headquarters in Washington to discuss the upcoming mission. Salinity influences ocean circulation and the global balance of freshwater and climate; until now, it has remained unmeasured by existing Earth Observing Satellites.
