Abstract:
Data release doi:10.5066/P9RIB5GC associated with this metadata record serves as an archive of single-beam bathymetric (SBB) data collected in July 2004 (Madison Bay) and August 2008 (Bully Camp, Point au Chien, Caminada, Fourchon, and Leeville) 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 U.S. Geological Survey’s (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 [OFR] 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.
Purpose:
Dissemination of processed SBB bathymetric data collected from Madison Bay, Louisiana in July 2004 (USGS Field Activity Number [FAN] 2004-303-FA [alternate FAN 04SCC03]). 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 at Madison Bay.
Supplemental_Information:
A limited number of water depths were collected along coring transects at nine study areas in 2002, 2003, 2006, and 2007 (USGS OFRs 2005-1216 and 2009-1158). In 2004 and 2008, SBB data were collected at the Madison Bay, Bully Camp, Point au Chien, Caminada, Fourchon, and Leeville study areas. SBB data were not collected at the Bay St. Elaine, Bayou Perot, DeLarge, or Ironton study areas. As part of FAN 2004-303-FA, SBB data were also collected at Little Pass Timbalier and Pass Abel, Louisiana in collaboration with researchers from the University of New Orleans. Those data were collected as part of a different project and will be published separately. These data are scientific in nature and are not to be used for navigation. Bathymetric grids interpolated from these point elevations should be used with caution and should use an appropriate grid cell size based on trackline spacing.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the processed data is determined during data collection. Offsets between the single-beam transducer and the Geographic Positioning System (GPS) antenna reference point (ARP) were measured during the survey and accounted for in post-processing. Bar checks were performed as calibration efforts to account for any drift in the Marimatech Echosounder. Differential Global Positioning System (DGPS) coordinates were obtained using post-processing software packages (National Geodetic Survey [NGS] On-Line Positioning User Service [OPUS], Automated GIPSY, Scripps Coordinate Update Tool [SCOUT] and Waypoint Product Group GrafNav, version 7.01).
Logical_Consistency_Report:
Bathymetric soundings were recorded using a Marimatech E-Sea 103 echosounder system in combination with a Teledyne Dynamic Motion Sensor (DMS-05). Position and elevation data were recorded using an Ashtech Z-Xtreme GPS receiver and choke-ring antenna. GPS data were recorded concurrently throughout the survey at a nearby base station (maximum baseline distance about 11.5 kilometers [km]) using a similar instrument combination. The final point (xyz) data are the result of merging the post-processed DGPS position data with the sounding data using the software package System for Accurate Nearshore Depth Surveying (SANDS), version 3.1.
Completeness_Report:
Data release doi:10.5066/P9RIB5GC associated with this metadata record includes the processed SBB position and elevation data for 26,172 point locations collected from Madison Bay, Louisiana in July 2004 (USGS FAN 2004-303-FA).
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All static base station sessions were processed through OPUS (https://www.ngs.noaa.gov/OPUS/), Automated GIPSY (https://apps.gdgps.net/index.php), and SCOUT (https://sopac-old.ucsd.edu/scout.shtml). The base-station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height). Base-station positional error was calculated as the absolute value of the final weighted solution minus the session position value. The maximum horizontal error of the base station coordinates used for post-processing was 0.00059 seconds latitude and 0.00080 seconds longitude.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
All static base station sessions were processed through OPUS, Automated GIPSY, and SCOUT. The base-station solutions were entered into a spreadsheet to compute a final, time-weighted positional coordinate (latitude, longitude, and ellipsoid height). Base-station positional error for each GPS session was calculated as the absolute value of the final weighted solution minus the session position value. For this survey, the standard deviation of the base station ellipsoid height was 0.013 meters (m) and the maximum vertical error for the base station was +/- 0.033 m.

Process_Description:
GPS Acquisition - Position and elevation data were recorded using an Ashtech Z-Xtreme GPS receiver, which recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via a choke-ring antenna. GPS data were recorded concurrently throughout the survey at a nearby base station (maximum baseline distance about 11.5 km) using a similar instrument combination. The base receiver and the rover receiver recorded their positions concurrently at 1-second (s) recording intervals throughout the survey.

Process_Description:
SBB Acquisition - The single-beam bathymetric data were collected aboard the 22-foot Research Vessel (R/V) Streeterville. HYPACK, a marine surveying, positioning, and navigation software package, managed the planned-transect information and provided real-time navigation, steering, correction, data quality, and instrumentation-status information to the boat operator. Planned tracklines were spaced approximately 500 m apart. Boat motion was recorded at 50-millisecond (ms) intervals using a Teledyne DMS-05 motion sensor. Depth soundings were recorded at 50-ms intervals using a Marimatech E-SEA-103 echosounder system. Data from the GPS receiver, motion sensor, and fathometer were recorded in real time and merged into a single raw data file (.RAW) in HYPACK, with each device string referenced by a device identification code and time stamped to UTC.

Process_Description:
GPS Processing - The coordinate values of the GPS base stations are the time-weighted average of the post-processed session values. The base station coordinates were imported into GrafNav, version 7.01 (Waypoint Product Group) and the data from the rover GPS were post-processed to the concurrent base-station session data; baseline distances were less than 11.5 km. The DGPS data were processed in the North American Datum of 1983 (NAD83) geodetic datum.

Process_Description:
SBB Processing - The raw bathymetric data and processed DGPS positions were merged using the System for Accurate Nearshore Depth Surveying (SANDS), version 3.1. SANDS is a single-beam acoustic (sounding), GPS-based hydrographic processing software package developed by the USGS for shallow-water bathymetric mapping. The merged, geometrically corrected SBB data were exported as x,y,z point data in the NAD83 (x,y) and NAVD88 GEOID03 (z) datums.
