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.

Ocean Data Access and Tools
NASA data span the geophysical parameters that characterize the global ocean and the physical processes operating within its depths and at its surface. Our datasets and tools help researchers translate these interconnected data points into actionable knowledge.

Surface Water and Ocean Topography (SWOT) Platform
SWOT provides detailed surface topography and monitors water body changes over time. The platform enables high-resolution ocean monitoring at 15-150 km spatial scales, tracking ocean currents, coastal dynamics, storm surges, and regional sea level changes. On land, SWOT measures water storage changes in lakes, reservoirs, rivers, and wetlands, supporting river discharge estimates for water resource assessment.
Researchers explore using SWOT data to derive two-dimensional estimates of sea ice thickness.
The Surface Water and Ocean Topography (SWOT) Swath Visualizer provides a visualization of two instruments’ coverage of Earth's surface: the Ka-band Radar Interferometer and altimeter.
SWOT presents opportunities and challenges in characterizing sea surface height anomalies.
