| Description |
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. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG-Y revision 1 format (Norris and Faichney, 2002). Processed sub-bottom profile images, survey trackline map, geographic information system (GIS) data, and formal Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM) are also provided.
