EAARL-B Pre and Post Bathymetry Elevation

The USGS Coastal and Marine Geology Program in collaboration with USGS National Geospatial Program , is developing three-dimensional (3D) topobathymetric elevation models for the Barnegat Bay estuary and adjacent coastline in New Jersey. Pre- and post-Hurricane Sandy aerial lidar surveys were conducted on Oct. 18-26, 2012 (pre-landfall) and Nov. 1-5, 2012 (post-landfall) with the USGS Experimental Advanced Airborne Research Lidar (EAARL) instrument, which acquires land elevation and water depth data simultaneously. These high-resolution USGS EAARL lidar surveys are key source data to model the submerged topography of Barnegat Bay at an unprecedented level of detail. USGS images created by Jeffrey Danielson.
