The purpose of this data release is to provide a new continuous elevation model of U.S. coastal environments from onshore to offshore for various coastal applications. This dataset was created to primarily supply a smooth coastal interface to inform groundwater models requiring continuous elevations from onshore to offshore. Alternative coastal elevation datasets either lack elevation data for both terrestrial topography and marine bathymetry, provide data for a specific region within the continental United States (i.e., not continuous for either the east or west coast), or contain sufficient artifacts from its creation to reduce the utility of the dataset for the purposes of providing constraints for coastal groundwater models. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S.
