In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Single-Beam Bathymetric Data Collected in 2004 and 2008 from the Mississippi River Delta Plain, Louisiana

Summary
This data release serves as an archive of single-beam bathymetric (SBB) data collected in July 2004 (Madison Bay study area; U.S. Geological Survey [USGS] Field Activity Number [FAN] 2004-303-FA) and August 2008 (Bully Camp, Point au Chien, Caminada, Fourchon, and Leeville study areas; USGS FAN 08SWL02) at six study areas in the Mississippi River Delta Plain (MRDP), Louisiana. Data were collected from historically formed open-water bodies as part of the USGS Gulf Coast Subsidence project to provide more extensive spatial coverage than water depths collected only along coring transects in 2002, 2003, 2006, and 2007 (USGS Open-File Reports 2005-1216 and 2009-1158). The bathymetric data were used to estimate magnitudes of one-dimensional (vertical) and three-dimensional (volume) accommodation that formed as a result of extensive historical wetland loss in Barataria and Terrebonne Basins in the MRDP. All bathymetric data are provided as x,y,z point data in the projected coordinate system North American Datum of 1983 (NAD83), Universal Transverse Mercator (UTM) Zone 15 North (15N) and all elevations are North American Vertical Datum of 1988 (NAVD88) orthometric heights, derived using the GEOID03 geoid model.
