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.

Summary
This data release archives processed single-beam bathymetry (SBB) data, collected from May 28-June 3, 2015 (USGS Field Activity Number 2015-315-FA) within Grand Bay Mississippi/Alabama, as part of the Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES). The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetland and estuarine environments. The data described in this report provide baseline bathymetric information for future research investigating wetland/marsh evolution, sediment transport, and recent and long term geomorphic change. The data will also support modeling of future changes in response to restoration and storm impacts. The survey area encompasses more than 40 square kilometers (km2) of Grand Bay's incorporated waters with more than 600 line-km of single-beam bathymetry data collected aboard two survey platforms: the RV Shark (Sub-cruise identifier 15CCT04) and the RV Chum (15CCT05). Final data files presented in this report are released in WGS84 (ITRF00) Ellipsoid Height (values range from -33.36 meters (m) to -29.53 m); NAD83 (CORS 96), NAVD88 orthometric heights, derived from the GEOID12A geoid model (values range from -3.95 m to -0.01 m); and NAD83 (CORS 96) Mean Lower Low Water (MLLW) (values range from -3.83 m to 0.11 m). Geographic Information System (GIS) data products include: a 10 m and 30 m cell-size interpolated bathymetry grids, trackline maps, point data files and formal Federal Geographic Data Committee (FGDC) metadata. For further information regarding data collection and/or processing methods refer to USGS Data Series 1070 (https://doi.org/10.3133/ds1070).
