Ocean Salinity Response to Hurricanes

This video screenshot shows hurricane-caused changes in sea surface salinity during the 2018 hurricane season. It is common to observe salinity increases where higher salinity water is brought to the surface by hurricanes and patches of salinity freshening due to storm-associated precipitation.

Using SMAP for Sensing Salinity

Launched on January 31, 2015, NASA’s Soil Moisture Active Passive (SMAP) mission measures global soil moisture and freeze/thaw state in the top 5 cm (2 in) of soil. SMAP data also are used to produce derived sea surface salinity (SSS) observations for the world’s oceans.


NASA's data policy ensures that all NASA data are available fully, openly, and without restrictions. Here's what this means to you.
