This point shapefile contains navigation of the shot points for the multichannel seismic survey that was conducted in the Atwater Valley area of the Gulf of Mexico during USGS cruise G1-03-GM aboard the R/V Gyre in the Gulf of Mexico in May, 2003. The purpose of this cruise was to collect multichannel seismic data in support of USGS and Department of Energy gas hydrate studies. About 253 km of data were collected along 35 short lines in and around lease block Atwater Valley 14 on the floor of the Mississippi Canyon.
This GIS overlay is a component of the U.S. Geological Survey, Woods Hole Science Center's, Gulf of Mexico GIS database. The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.

No additional checks for topological consistency were performed on the data.
Information unavailable from original metadata.
Navigation file exported from seg-y headers in ProMAX and saved to Marfac Snap2. NOTE: Navigation reflects the location of the GPS antenna. Shift to the actual shot location will be applied later.

Navigation file opened in MS Excel, arc milliseconds for X and Y coordinates were converted to decimal degrees (by dividing the each of the arc-millisecond values by 3,600,000 and creating the two new attribute fields X_DD and Y_DD) [excel file ##to##sda.xls]. A header line was added to the table in Excel.

Navigation (corrected with a shift to reflect the shot location) taken back into ProMAX. Then file of CDP locations (g1cdp.nav) exported from ProMAX. File split into kc_cdp.nav and av_cdp.nav, then awk script to reformat the output. CDP points into ArcView 3.3 and saved as shapefiles g1cdp_nav_kc_geo.shp and g1cdp_nav_av_geo.shp.

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. The link to the larger work citation had to be fixed. 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.
