Geospatial Navigational Data Associated with Chirp Sub-Bottom Profiles Collected During USGS Field Activity Number 2024-310-FA in 2024 from Wallops and Assawoman Islands, Virginia

In June 2024, the U.S. Geological Survey (USGS) conducted a nearshore geologic assessment, including bathymetric mapping, near Wallops and Assawoman Islands, Virginia (VA). This work was performed to collect bathymetry to initialize hydrodynamic models and acquire new sub-bottom profile data to connect with existing USGS offshore lines collected along the Delmarva Peninsula, Maryland and VA, in 2015 (Sweeney and others, 2015). These newly acquired datasets will be used to help evaluate impacts of shoreface engineering activities on system ecogeomorphology. Geophysical data were collected as part of the USGS Interconnected Coastal Environments at Decadal Timescales and Coastal Sediment Availability and Flux (CSAF) projects; more information about the CSAF project can be found at https://usgs.gov/csaf. The data release associated with this metadata record serves as an archive of high-resolution chirp sub-bottom trace data and navigation files. Shapefiles (.shp) provided in the data release represent point and polyline vector datasets of Field Activity Number (FAN) 2024-310-FA chirp sub-bottom profile tracklines, start of lines, and 1,000-shot-interval locations.
