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

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.
