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 Waves Data Access and Tools
Ocean waves data from NASA range from regularly updated high-resolution Sentinel-1 radar imagery to historical Seasat data. Our datasets and tools help users find and integrate the data they need to learn more about the nature of ocean waves and their contributions to sea and coastal processes.

Featured Ocean Waves Observation Method: GNSS
Data from a Global Navigation Satellite System (GNSS), such as global positioning system (GPS) measurements, can be used to estimate the strength and direction of tsunamis following an earthquake by calculating how much land moved near water and the energy transmitted into the ocean.
Join us on Sept. 28 to learn about the NASA Making Earth System Data Records (ESDR) for Use in Research Environments (MEaSUREs) Extended Solid Earth Science ESDR System (ESESES) project, whose Global Navigation Satellite System (GNSS)-derived data products enable research on tectonic motion, crustal deformation, earthquakes, tsunamis, sea level rise, extreme weather, and more!
Learn how to use the GNSS-based Upper Atmospheric Realtime Disaster Information and Alert Network (GUARDIAN) ionospheric monitoring software to supplement early warning systems (EWS) detections of natural hazards such as tsunamis, volcanic eruptions, earthquakes, and geomagnetic and solar storms.
