Description:
Abstract:
This ArcView GIS data layer contains the navigation fix points for the R/V FARNELLA 90-3 cruise.
Purpose:
The trackl.shp file shows the R/V FARNELLA 90-3 trackline. This GIS overlay is a component of the U. S Geological Survey, Woods Hole Field Center's, Gulf of Mexico ArcView 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.
Supplemental_Information:
This file contains only the locations of the individual navigation points. Navigation fixes were recorded in the mrg-mrg format at a two minute interval. The date and time information is contained as attribute information in the trackp.shp file.
