Archive of Chirp Subbottom Profile Data Collected in 2019 from Cedar Island, Virginia

Metadata Updated: July 6, 2024

From August 9 to 14, 2019, researchers from the U.S. Geological Survey (USGS) conducted a geophysical survey to investigate shoreface morphology and geology near Cedar Island, Virginia. The Coastal Sediment Availability and Flux project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving storm-related impacts, post-storm beach response, and recovery. This publication serves as an archive of high-resolution chirp subbottom data, survey trackline map, navigation files, geographic information system (GIS) data, and formal Federal Geographic Data Committee (FGDC) metadata. Processed subbottom profile images are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG Y revision 0 format (Barry and others, 1975). In addition to this data release, the SEG Y files can be downloaded from the USGS Coastal and Marine Geoscience Data System (CMGDS) at, Bathymetry and backscatter data were also collected during this survey are available in Stalk and others (2020).
