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 Circulation Data Access and Tools
NASA has ocean circulation datasets that help researchers characterize the currents and flow of water within Earth's oceans. Access a range of data and data tools such as AppEEARS, Worldview, and Giovanni to make the most of ocean circulation data.

Featured Ocean Circulation Observation Method: SWOT
NASA's Surface Water and Ocean Topography (SWOT) platform monitors Earth’s surface water and measures how water bodies, such as lakes and rivers, change over time. SWOTS measures water surface heights using its primary instrument, the Ka-band Radar Interferometer (KaRIn).
Recently released datasets from the SWOT mission provide scientists with previously unavailable measurements of Earth's surface water.
