    • Coastal Single-Beam Bathymetry and Beach Elevation Data Collected in 2024 From Wallops and Assawoman Islands, Virginia

    Metadata Updated: September 14, 2025

    The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected single beam echosounder (SBES) and differential global positioning system (DGPS) elevation data in the nearshore and beach environments of Wallops and Assawoman Islands, Virginia, in June 2024. This USGS data release includes the processed SBES and DGPS elevation point data (xyz) for Field Activity Number (FAN) 2024-310-FA. The SBES data were acquired using survey equipment mounted on personal watercrafts (PWCs) R/V Chum and R/V Shark, and the DGPS data were acquired using GPS antennas mounted on a utility terrain vehicle (UTV) or GPS backpack. Multibeam echosounder (MBES) and chirp seismic data were collected concurrently as part of FAN 2024-310-FA; those data are available as separate data releases (Forde and others, 2025; Bemelmans and others, 2025).
