We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project

Sea Ice Data Access and Tools

NASA has sea ice datasets that help researchers characterize the presence and extent of ice in the ocean. Access a range of data and data tools such as AppEEARS, Worldview, and Giovanni to make the most of sea ice data.

Featured Sea Ice Observation Method: ICESat-2

NASA's Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) carries a laser altimeter scientists use to measure the elevation of ice sheets, glaciers, sea ice, and more in unprecedented, 3-D detail. The satellite also measures heights across Earth's temperate and tropical regions, and takes stock of the vegetation in forests worldwide.
