Coastal Multibeam Bathymetry and Backscatter Data Collected in June 2024 From Wallops and Assawoman Islands, Virginia

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: August 06, 2025 | Last Modified: 20250513
The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected multibeam echosounder (MBES) bathymetry and sonar backscatter data offshore of Wallops and Assawoman Islands, Virginia in June 2024. This USGS data release includes the corresponding processed MBES-derived elevation points (xyz) and a backscatter mosaic (tag image file format [TIFF]) as part of Field Activity Number (FAN) 2024-310-FA. MBES and backscatter data were acquired using two Teledyne Reason SeaBat T50-P MBES in a dual-head configuration. Additionally, nearshore single-beam echosounder (SBES) and land topographic elevations, as well as Chirp seismic data, were concurrently collected as a part of FAN 2024-310-FA; those data are available as separate data releases (Lyons and others, 2025; Forde and others, 2025).
