Abstract:
In 2010, the U.S. Geological Survey in Woods Hole, MA and St. Petersburg, FL, in partnership with the U.S. Army Corps of Engineers, Mobile District conducted geologic mapping to characterize the seafloor and shallow subsurface stratigraphy offshore of the Gulf Islands of Mississippi. The mapping was carried out during two cruises in March, 2010 on the R/V Tommy Munro of Biloxi, MS. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (both 234 kHz and 468 kHz systems), a Klein 3000 and a Klein 3900 dual frequency sidescan-sonar, and an Edgetech 512i chirp subbottom profiling system. The long-term goal of this mapping effort is to produce high-quality, high-resolution geologic maps and geophysical interpretations that can be utilized to identify sand resources within the region and better understand the Holocene evolution and anticipate future changes in this coastal system. More information on the field work can be accessed from the Woods Hole Coastal and Marine Science Center Field Activity webpage https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-012-FA or the St. Petersburg Coastal and Marine Geology InfoBank https://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html.
Purpose:
This shapefile represents 1-meter interval bathymetric contours of swath data that were collected in 2010. These data are used to define the sea-floor morphology offshore of the Gulf Islands in Mississippi.

Data_Quality_Information:
Logical_Consistency_Report: Any spurious data points were removed during processing.
Completeness_Report:
All shore parallel survey lines were incorporated. Tie (shore perpendicular) lines were not used in grid generation. The R/V Tommy Munro was contracted for the month of March 2010. The Woods Hole Coastal and Marine Science Center acquired data onboard between March 4 and March 17, 2010. Bathy data were acquired on 20100304-20100309; 20100311;20100315-20100317. Day gaps in acquisition were due to inclement weather or seismic tieline acquisition. The St. Petersburg Coastal and Marine Science Center acquired data onboard the R/V Tommy Munro between March 19 and March 29, 2010. Bathy data for this dataset were acquired on 201003019-20100320; 20100327-2010329. Day gaps in acquisition were due to inclement weather or data acquisition in another survey area.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
These data were navigated with a Differential Global Positioning System (DGPS); they are accurate to +/- 1 to 2 meters, horizontally. Unless noted, all DGPS data are referenced to WGS84, and distance between sidemounted interferometric sonar and GPS antennae are corrected.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The theoretical vertical resolution of the SEA Ltd SwathPlus interferometric sonar is 1 % of water depth, approximately 0.1 m within the study area. An Octopus F180 Attitude and Positioning system was used to correct for vessel roll, pitch, heave, and yaw during the first leg, 2010-012FA, whereas an Octopus F190 Attitude and Positioning system was used during the second leg, 10cct02. Tidal offsets were corrected with a NOAA tide zone model and referenced to mean lower low water (MLLW). Errors associated with the tidal zone model could be less than or equal to the tidal range for this area which is ~0.4 m. The gridding algorithm and cell size used on these data could introduce errors as great as 3 m along the edges of the Gulfport Ship Channel. Gridding-induced errors are likely much smaller (< 0.5 m) for most of the study area where slopes are less than 1 degree. Changes in ship draft due to water and fuel usage were not considered.

Swath data acquisition at sea (2010): These bathymetric data were collected with 2 SEA Ltd Swathplus interferometric sonars (a 234 kHz and a 468 kHz system) mounted on the portside of the R/V Tommy Munro of Biloxi, MS. The WHCMSC acquired data with the 234 kHz system between March 4, 2010 and March 17, 2010. The St. Petersburg Coastal and Marine Science Center acquired data with the 468 kHz system between March 19, 2010 and March 29, 2010. All data were acquired with SwathPlus Software (version: 3.6.5). Tracklines are spaced 150 m apart in the shore parallel direction.
Process_Step:
Process_Description:
SwathPlus Software (version: 3.7.0) was used to acquire the raw swath data (*.sxr) and output a processed soundings file (*.sxp). Several bathy filters were applied to the processed file within SwathPlus to remove erroneous soundings and reduce the density of the data. Corrections were also applied for speed of sound changes (using sound velocity profiles), ship motion, GPS antennae offsets, and transducer depth and angle below the surface. Bathy filters included a low amplitude (100), range (1-m below the surface), box (2-m to avoid nadir), alongtrack 1 (depth difference of 10-m, window size 10-m, and learn rate of 0.6), alongtrack 2 (depth difference of 1-m, window size 1-m, and learn rate of 0.9), and a mean filter (0.1-m).

Process_Description:
CARIS (version: HIPS and SIPS 6.1; service pack 2) was used to import the processed bathy files (*.sxp) from SwathPlus format to CARIS HDCS data format using the conversion utility. The data were corrected for errors in soundings due to additional sound refraction not accounted for by sound velocity profiles using the CARIS refraction editor. These artifacts can be recognized in a cross-swath profile of a relatively flat patch of sea floor. When viewing the swath data across a profile, the sea floor will appear to have a "frown" or "smile" when in fact the data should be flat across the profile. Insufficient and/or erroneous sound velocity information, which is usually due to too widely spaced or non-existent velocity profiles within an area, results in an under or over-estimate of water depth which increases with distance from the center of the swath. The bathymetric data were also corrected to mean lower low water (MLLW) using a discrete tidal-zoning model (DTZ) developed by NOAA/NOS's Hydrographic Planning Team (Huang, personal communication, 2010) (<http://www.tidesandcurrents.noaa.gov/hydro.html>). The DTZ model corrects differences in tidal phase and amplitude between the survey area and observations made at NOS tide gauges at Gulfport Harbor (8745557) and Pascagoula NOAA Lab (8741533). The tidal zone models were imported into CARIS (version: HIPS and SIPS 6.1) as text files and used to correct tidal observations for each survey. Once the tidal zone model was imported into CARIS using the tide editor, the tidal range and phase offsets were applied and remerged in CARIS(version: HIPS and SIPS 6.1), making all the soundings relative to MLLW. A 5-meter base surface of tide corrected bathymetric soundings was created in CARIS, then exported as ASCII x,y,z data.

Process_Description:
The 5-m ASCII x,y,z file (for each cruise; St. Pete and WHCMSC) was gridded in GMT (version: 4.2.1; Wessel and Smith, 1998) using 'blockmedian' with a cell size of 50 meters. This routine was conducted to minimize edge effects in the 'surface' gridding routine because these data were collected at approximately 40-50% seafloor coverage. Next a tension spline routine (at 0.1) in GMT was used ('surface') to create a netCDF grid.

The projection was defined in ArcMap (version: 9.3) using Data Management Tools - Projections and Transformations - Define Projection: UTM, zone 16N, WGS84 Datum. This grid was then reprojected with ArcToolbox (Data Management Tools - Projections and Transformations - Raster - Project Raster) to create a grid in geographic coordinate system WGS84.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Added a landing page link as the first link in the identification section. Updated the link to the field activity. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
