Summary:
- NASA's ocean science missions and projects focus on studying the Earth's oceans, including their role in the global climate, sea level changes, and ocean ecosystems.
- Key missions include the Soil Moisture Active Passive (SMAP) satellite, which measures soil moisture and ocean salinity, and the upcoming Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission, which will study ocean biology and its interactions with the atmosphere.
- NASA also collaborates with other agencies and organizations to conduct research on topics such as ocean currents, sea ice, and the impact of climate change on the oceans.
