Data Series 835
A team of scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center, collected 92 line-kilometers of dual-frequency single-beam bathymetry data in the tidal creeks, bayous, and coastal areas near Weeks Bay, southwest Louisiana. Limited bathymetry data exist for these tidally and meteorologically influenced shallow-water estuarine environments. In order to reduce the present knowledge gap, the objectives of this study were to (1) develop methods for regional inland bathymetry mapping and monitoring, (2) test inland bathymetry mapping system in pilot locations for integrating multiple elevation (aerial and terrestrial lidar) and bathymetry datasets, (3) implement inland bathymetry mapping and monitoring in highly focused sites, and (4) evaluate changes in bathymetry and channel-fill sediment storage using these methods.
This report contains single-beam bathymetric data collected between January 14 and 18, 2013. Data were collected from the RV Mako (5-meter vessel) in water depths that ranged from <1 meter to 7.7 meters. Locations of data collection ranged from open-bay systems to narrow inland tidal creeks (U.S. Geological Survey Field Activity Number 13CCT01).
This report serves as an archive of processed bathymetry data. Geographic information system data provided in this document include a 10-meter cell-size interpolated gridded bathymetry surface, and trackline maps. Additional files include error analysis maps, Field Activity Collection System logs, and formal Federal Geographic Data Committee metadata.
Do not use these data for navigational purposes.
We would like to thank our USGS collaborators Cindy Thatcher from the USGS in Reston, Va., Dustin Kimbrow from the USGS Alabama Water Science Center in Montgomery, Ala., and Dean Gesch and Jeffrey Danielson from the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, S. Dak., for their contribution to the survey. We would like to thank the Morton Salt Plant Weeks Island, La., location for allowing the USGS access to their property for GPS base station occupations. Great thanks and appreciation go to Darrell Anders at the USGS National Wetland Research Center Lafayette, La., for providing materials and repairs in the field on short notice. We would also like to acknowledge help with Web design, and general support from the following people: Jolene Gittens, Noreen Buster, Lance Thornton, and Kyle Kelso. Reviews of this document were conducted by Kara Doran and Arnell Forde of the St. Petersburg Coastal and Marine Science Center.
