| Description |
A team of scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), collected 92-line-kilometers (km) 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 an inland bathymetry mapping system, in pilot locations, for the purpose of 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. This report contains single-beam bathymetric data collected between January 14 and 18, 2013(USGS Field Activity Number 13CCT01). Data were collected from the R/V Mako (5-m vessel) in water depths that ranged from <1 m to 7.7 m. Locations of data collection ranged from open-bay systems to narrow inland tidal creeks. Do not use these data for navigational purposes. [More]
