    "descript": "In June\/December 2021 and July 2022, the U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers, Engineer Research and Development Center (USACE-ERDC) conducted repeat, nearshore geologic assessments, including bathymetric mapping, near Duck, North Carolina (NC). This work was performed in support of efforts to map the shoreface, characterize stratigraphy, and investigate changes in seafloor elevations near the USACE Field Research Facility and to measure the co-evolution of the morphology and geology of the shoreface before\/after a storm and during recovery. Geophysical data were collected as part of the USGS Coastal Sediment Availability and Flux and DUring Nearshore Event eXperiment (DUNEX) projects. 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 Numbers (FANs) 2021-326-FA and 2022-326-FA chirp sub-bottom profile tracklines, start of lines, and 1,000-shot-interval locations.",
