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 shapefile shows the tracklines along which single-channel seismic-reflection profiles were collected in 1997 aboard the R/V GYRE. The survey focused on the Bryant Canyon turbidite pathway, which crosses the Louisiana continental slope. 562 km of single-channel seismic data were collected during this cruise.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Navigation data were collected using both Differential GPS and P-CODE GPS receivers. The GI Airgun was towed 10 m aft of the ship. The two-channel streamer was towed approximately 100 m aft of the ship, and each channel was 25 m long.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The airgun was towed at a depth of approximately 1 meter. The streamer was towed at a depth of approximately 5 m. There was no correction to a datum such as mean sea level.

Process_Description:
The time, latitude, and longitude fields were extracted from the raw data files, written to a text file, filtered to extract fixes at a 1-minute interval, edited to include only the intervals of time when seismic data were being collected, imported to ArcView, and converted to a shapefile showing a line along which the seismic data were collected.
