Description:
Abstract:
Since 1982, the U.S. Geological Survey (USGS) has collected a large amount of surficial and shallow subsurface geologic information in the deep parts of the Gulf of Mexico. These data include digital sidescan sonar imagery, digital seismic-reflection data, and descriptions and analyses of piston and gravity cores. The data were collected during several different projects that addressed surficial and shallow subsurface geologic processes. Some of these data sets have already been published, but the growing interest in the occurrence and distribution of gas hydrates in the Gulf of Mexico warrants integrating these existing data and associated interpretations into a GIS to provide regional background information for ongoing and future gas hydrate research.
Purpose:
This GIS data layer is a 25 m version of the completed SeaMARC 1A sidescan sonar image mosaic, which has been enhanced and projected to geographic using the WGS 84 datum. The SeaMARC 1A imagery was collected in 1990 from the eastern part of the Mississippi Fan and covers an area of 3,047 km2. An interpretation of these data is presented by Twichell et al. (1992) and Twichell et al. (1995).

Process_Description:
The individual SeaMARC 1A sidescan swaths were transferred from tape to disk. The files were subsequently converted from the QMIPS format to a WHIPS format for processing. The WHIPS format and processing procedures are described in Paskevich (1992).

The individual sidescan files were processed using the Woods Hole Image Processing Software (WHIPS, Paskevich, 1992). The individual strips of sidescan data were processes to apply geometric (i.e. slant-to-ground range corrections) and radiometric corrections (i.e. beam correction shading and striped noise removal).

Process_Description:
The SeaMARC 1A files that comprised the eastern half of the survey were transferred to the Woods Hole Science Center's MicroVAX-II computer system. This portion of the survey consisted of mostly straight line segments and were to be digitally mosaicked on this system. (The western portion was done a few months later with developing software). The MicroVAX-II computer system contained the Mini-Image Processing System (MIPS) software that was needed to map and digitally mosaic the data. To begin processing, the WHIPS data files were all converted to MIPS format.

Process_Description:
As the individual swaths were mapped, they were geo-referenced to the base image, stenciled and mosaicked to the base. (The base was one swath that had been mapped and was selected as the master which everything would be registered with). Control points were selected interactively to match features on the adjacent lines and a rubber sheeting procedure was applied to the mapped swaths to better align the images. Once registered, a stencil line was interactively drawn around the area of the line to be added. This stencil area was critical as it not only eliminated the unwanted area that was overlapping the adjacent lines, but defined the area to be kept. Finally, the registered, transformed and stenciled image was added to the base. These steps were repeated for each swath until the eastern mosaic was completed.
