Holcomb Nan Wang Ling Zhu 20220801 1 spreadsheet Reston VA U.S. Geological Survey https://doi.org/10.5066/P9I0B0X4 This dataset contains field topographic and bathymetric data measured during February to April 2019 across oyster castles and mud flats along the Chincoteague Living Shoreline, Virginia, where constructed oyster reefs (CORs, aka oyster castles) were installed to protect the shoreline and enhance habitat for oyster and other species. This dataset is used for the assessment of living shoreline structure (oyster castles) effects on wave, current velocity, and sediment dynamics. It can also be used for topographic and bathymetry data updates for fine resolution hydrodynamic and wave modeling along coastal shorelines.

Rydlund Brenda K. Densmore 20120921 publication https://pubs.usgs.gov/tm/11d1/ Vertical accuracy is 0.10 feet. The accuracy of elevation survey was determined using point measurements at a reference location. Data were checked and all values fall within expected ranges. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Horizontal accuracy, 0.05 feet, is determined by point measurements at a control point. Vertical accuracy is 0.10 ft. Global Navigation Satellite System (GNSS) positioning was used to establish the elevation of the benchmark above NAVD88. All satellite surveys were conducted with a Trimble R10 antenna and TSC3 controller adhering to USGS Level III standards (Rydlund and Densmoore, 2012). 20190430 William D Capurso U.S. Geological Survey, NORTHEAST REGION Hydrologic Technician mailing and physical
