Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 08:48 PM | Dataset Last Updated: September 22, 2021 at 12:00 AM
The U.S. Geological Survey (USGS), in cooperation with the University of New Orleans (UNO) and the Louisiana Department of Natural Resources (LDNR), conducted a high-resolution, single-beam bathymetric survey along the southern Louisiana coastal zone from Belle Pass to Caminada Pass. The survey consisted of 483 line-kilometers of data acquired in July and August of 2005. This report outlines the methodology and provides the data from the survey. Analysis of the data and comparison to a similar bathymetric survey completed in 1989 show significant loss of seafloor and shoreline retreat, which is consistent with previously published estimates of shoreline change in the study area.
