Description:

Abstract:: During the summers of 2008 and 2009 the USGS conducted bathymetric surveys from West Ship Island, Miss., to Dauphin Island, Ala., as part of the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazard Susceptibility project. The survey area extended from the shoreline out to approximately 2 kilometers and included the adjacent passes. The bathymetry was primarily used to create a topo-bathymetric map and provide a base-level assessment of the seafloor following the 2005 hurricane season. Additionally, these data will be used in conjunction with other geophysical data (chirp and side scan sonar) toward constructing a comprehensive geological framework of the Mississippi Barrier Island Complex. The culmination of the geophysical surveys will provide the data necessary for scientists to define, interpret, and provide baseline bathymetry and seafloor habitat for this area and to aid scientists in predicting future geomorpholocial changes of the islands with respect to climate change, storm impact, and sea-level rise. Furthermore, these data provide information for feasibility of barrier island restoration, particularly in Camille Cut, and efforts for the preservation of historical Fort Massachusetts.
Purpose:: This report serves as an archive of the processed single-beam and swath bathymetry data. Data products herein include gridded and interpolated surfaces, surface images, and x,y,z data products. Additional files include trackline maps, GIS files, Field Activity Collection System (FACS) logs, and formal FGDC metadata. Scanned images of the handwritten FACS logs are also provided as PDF files. Refer to the Acronyms page for expansion of acronyms and abbreviations used in this report.
Supplemental_Information:: For navigational purposes, bathymetric surveys have traditionally been referenced to a water level datum using tide gages and tide models. Bathymetric measurements referenced to a Global Positioning System (GPS) is a more accurate way of representing water depth and has been implemented in the acquisition and processing procedures for these datasets. Previous single-beam bathymetric studies performed at the USGS Center for Coastal and Marine Science have successfully referenced bathymetric measurements to GPS (DeWitt and others, 2007; Hansen 2008 and 2009). These surveys were conducted as a test to develop acquisition technology utilizing both single beam and swath bathymetry survey methods together and referencing both types of measurements to GPS rather than water level. Therefore, this survey is considered a seafloor-elevation survey and is explained in greater detail within this report. To accommodate coverage of this area in a limited timeframe, this seafloor-elevation survey was conducted using three techniques; single-beam bathymetry, interferometric swath bathymetry, and a walking kinematic survey of the island shorelines. All three techniques utilized GPS measurements. Implementation of these techniques was executed concurrently yet independently aboard two research vessels: the RV Survey Cat, a 26-foot (ft) shallow draft Glacier Bay Coastal Runner, and the 50-ft RV G.K. Gilbert. A portable push buggy with a rigid antenna-mount served as the platform for the kinematic shoreline survey. Data from each survey technique was post-processed and edited independently with proper inclusion of the differentially processed external navigation files. The x,y,z components from each method were then combined and the two survey years (2008 and 2009) were merged into one dataset. Chirp seismic data were also collected during these surveys and are archived separately.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The accuracy of the data is determined during data collection. These datasets are from four speperate research cruises and are therefore internally consistent. Methods are employed to maintain data collection consistency aboard various platforms. During mobilization, each piece of equipment (single beam and swath) is isolated to obtain internal and external offset measurements with respect to the survey platform. All the critical measurements are recorded manually and digitally and entered into their respective programs for calibration. Once calibration is complete and calibration status is considered acceptable, then survey operations commence. Each system has a dedicated computer, and efforts are made to utilize the same equipment and software versions. However, upgrades and changes occur and require additional setup, measurements, and notation. For the single beam bathymetry, offsets between the single beam transducers and the Ashetch antenna reference point (ARP) were measured and accounted for in post-processing. Bar checks were performed as calibration efforts and accounted for any drift in the Marimatech Echosounder. The Differential Geographic Positioning (DGPS) was obtained using post-processing software packages. For the swath bathymetry, offsets between the sonar head and the DGPS antennas were measured and entered into the F190 internal setup program. DGPS is normally provided through the OmniSTAR High Performance wide-area GPS service unless otherwise noted. DGPS is always implemented for navigational accuracy either during acquisition or as a post-processing step.

Logical_Consistency_Report:

These datasets were completed on four research cruises over the course of 21 days for 2008 and 20 days for 2009. Refer to the FACS logs for respective vessel platforms and survey information. This dataset was created to show the combination bathymetry and topography from the cruises. The grid is 50-m spacing.

Completeness_Report:

This is a complete processed bathymetry and shoreline topography surface in GeoTIFF format. It is a combination of single beam and swath bathymetry and shoreline topography from USGS cruises 08CCT01, 08CCT02, 09CCT03, and 09CCT04. These data provide a continuous and complete surface; however, there may in some cases be data missing and inconsistent with reported tracklines. This is directly due to the exclusion of poor data and (or) instrument failures.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

GPS base stations were erected within approximately 15 to 20 km of the survey area. Efforts were made to utilize pre-existing National Geodetic Survey (NGS) benchmarks on the islands. If pre-existing benchmarks were unavailable a USGS benchmark was installed.
All static base station sessions were run through On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The base location results from OPUS were put in a spreadsheet for error analysis and averaging, and any outliers were removed. For the 2008-2009 base station occupations, results were considered sufficient and produced +/-3.3 cm or less accuracy in the vertical component. These base station positions, once finalized, were used for processing and can be found in the FACS logs.
GPS was recorded using Ashtech Z-Xtreme GPS receivers that record the 12-channel full-carrier-phase positioning signals (L1/L2) from the satellites via the Thales choke-ring antenna. This GPS instrument combination is duplicated on the survey vessel (rover). The base receiver and the rover receiver record their positions concurrently at 1-second (s) recording intervals throughout the survey period. The differential navigation for the single-beam bathymetry and the swath bathymetry were both collected in the same manner.

Vertical_Positional_Accuracy_Report:

Ship motion was measured using a the CodaOctopus Octopus F190 Precision Attitude and Positioning System. The interferometric sonar is an angle-measuring system; depth accuracy decreases with increasing horizontal range. The swath width of the interferometric sonar varied as a function of depth but generally achieved 5 times the water depth. Vertical accuracy is directly affected by the accuracy of both the navigation system and the sonar system.

Process_Description:

Differentially Corrected Navigation Process: Each base station GPS file was processed to the respective roving survey platform GPS file using GrafNav version 8.10, a product of Waypoint Product Group. During this process, steps were taken to ensure that the trajectory produced from the base to the rover was clean and produced fixed positions. From these processes a single differentially corrected, precise position at 1-s intervals for each roving GPS session was created.

Process_Description:

Swath Post-Processing 2008: The raw swath files, (SXR) were run through SWATHplus version 3.06.04.03. The external differential navigation file was substituted for the F190 navigation string, however, the motion (heave, roll, pitch) from the F190 was applied and depths were geometrically corrected. The processed swath files (SXP) were referenced to NAD83, UTM ZONE 16N NAVD88. The SXP files were imported into CARIS HIPS and SIPS version 7.0 with the respective vessel files and merged. Each line was viewed and cleaned in Swath Editor. The filters applied included depth, beam to beam slopes, across-track distance, and missing neighbors. The files were remerged after any changes occurred during the editing process, a 5-m BASE surface was created, and the x,y,z data were exported in ASCII format for further grid interpretation. The x,y,z values were in NAD83, UTM ZONE 16N NAVD88.

Swath Post-Processing 2009: The SXRs were run through SWATHplus version 3.06.0 without inserting the differential external navigation file. The processed SXP data were imported into CARIS HIPS and SIPS version 6.1. The external navigation files were first smoothed in Matlab version R2007b. The external navigation files were then imported into CARIS with the heave correction (waterline height) offset in the respective vessel file and the navigation data applied as a tide file in CARIS during the merge process. Each line was viewed and cleaned in Swath Editor. The filters applied included depth, beam to beam slopes, across-track distance, and missing neighbors. The files were remerged after any changes occurred during the editing process, a 5-m BASE surface was created, and the x,y,z data were exported in ASCII format for further grid interpretation.
