Salt is essential
Circulating through our bodies and our seas, it impacts the health of people and the planet. Salt dissolved in seawater – measured as salinity – drives currents that distribute heat and carbon around the globe. So, salt not only preserves our food, it helps to preserve our climate by contributing to global ocean circulation.
Earth is an ocean planet
Key water cycle processes – precipitation and evaporation – mostly occur over the ocean. Thus, monitoring sea surface salinity patterns provides important clues about changes in our environment.
NASA observes salinity
Merging data from satellites and other instruments, our mission is to better understand ocean circulation, the water cycle, and climate.
