Description:
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 <http://quashnet.er.usgs.gov/data/2010/10012/> or the St. Petersburg Coastal and Marine Geology InfoBank <http://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html>.
Purpose:
This GeoTIFF (Tagged Image File Format) contains sidescan sonar data that were collected in March 2010. These data are used to define the sea-floor morphology offshore of the Gulf Islands in Mississippi.

Attribute_Accuracy:
Logical_Consistency_Report:
All sidescan data were collected during USGS-St. Petersburg cruise 10cct02 using a Klein 3900 dual frequency sidescan-sonar towfish and an Octopus F190 Attitude and Positioning System. Quality control was conducted during processing of the data. Any spurious data or artifacts were removed or minimized.
Completeness_Report:
All available data within the mosaic area were used to create the backscatter mosaic.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
These data were navigated with a Differential Global Positioning System (DGPS) mounted above the interferometric sonar head. Unless noted, all DGPS data are referenced to WGS84. The layback distance between towed sidescan sonar fish and the mounted GPS antennae are uncertain and a correction for distance between fish and GPS antennae may not have been supplied in the Klein SonarPro acquisition software. The differential GPS is accurate within 1 to 2 meters. The layback of the towfish adds additional uncertainty due to changes in angle and scope of the tow cable in response to sea state and vessel speed. The total horizontal uncertainty is + or - 10 meters.

Sidescan-sonar (acoustic-backscatter) data during the second leg (10cct02) were acquired with a Klein 3900 dual-frequency sidescan-sonar system (445 and 900 kHz), which was towed approximately 3 m astern from a starboard-side davit. Klein SonarPro acquisition software was used to log the data digitally at a sample rate resulting in raw pixel resolutions of approximately 0.18 and 0.14 m in the across-track and along-track directions, respectively. The Klein system produced useable data over swath widths of 100-200 meters during leg 10cct02.
Process_Step:
Process_Description:
Within XSonar Software (version: 2.0) a median filtering routine (Malinverno and others, 1990) was applied to the raw sidescan-sonar data (.xtf) to remove speckle noise; the filter was 4 pixels across track by 3 pixels along track. The data were further processed to correct for fish altitude, slant and beam artifacts, and then merged with the navigation (Danforth, 1997). Odd and even sidescan sonar lines were mapped separately out of XSonar at 1 meter/pixel resolution. Sidescan areas were defined within the cruise domain such that the sonar images mapped in XSonar would be no larger than 150 Mb.

Process_Step:
Process_Description:
The odd and even area files were imported into PCI Geomatica Software (version 10.1) to be digitally mosaicked together using PCI's OrthoEngine and procedures described in Paskevich (1996). The mosaicking process produces an enhanced, geographically correct, sidescan-sonar mosaic with 1 meter/pixel resolution. The composite mosaic was exported as a GeoTIFF image.

Overview_Description:
Entity_and_Attribute_Overview:
There are no attributes associated with a GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). The background color is set to 255 and can be turned off without removing data values.
