A new ATLAS/ICESat-2 L3A Along Track Coastal and Nearshore Bathymetry, Version 1 dataset is available at NASA’s National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This product contains global along-track coastal and nearshore bathymetry, consisting of refraction-corrected seafloor and sea surface heights (orthometric and ellipsoidal heights and instantaneous depths), as well as associated uncertainties. The data are derived from ATLAS/ICESat-2 L2A Global Geolocated Photon Data (ATL03).
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.
