This dataset contains trackline navigation for approximately 680 km of EdgeTech SB-512i chirp seismic-reflection data collected by the U.S. Geological Survey during Woods Hole Science Center cruise 07011 off the southern shore of Martha's Vineyard, 2007. These lines, in conjunction with the shot-point navigation can be used to correlate the seismic-reflection profiles with other data in the GIS.
Are there legal restrictions on access or use of the data?
