Remote Sensing of Salinity and Overview of Results from Aquarius[24-Dec-15] Aquarius is a combined active/passive microwave (L-band) instrument designed to map the salinity of global oceans from space. The specific goal of Aquarius is to monitor the seasonal and interannual variation of the large scale features of the sea surface salinity (SSS) field of the open ocean (i.e. away from land).

Ocean Circulation[10-May-11] Ocean circulation plays a key role in distributing solar energy and maintaining climate, by moving heat from Earth's equator to the poles. Aquarius salinity data, combined with data from other sensors that measure sea level, rainfall, temperature, ocean color, and winds, will give us a much clearer picture of how the ocean works.
Water Cycle[10-May-11] Measurements of sea surface salinity, or the concentration of salt at the ocean's surface, gives scientists vital information on global ocean circulation and how freshwater moves between the ocean and other reservoirs.
Climate[10-May-11] With its accurate and consistent salinity measurements, Aquarius will help climate modelers to better understand the ocean-atmosphere processes that are changing Earth's climate.
