This dataset contains trackline navigation for approximately 253 km of EdgeTech SB-424 chirp seismic-reflection data collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center in 2010. The seismic-reflection data are used to define sub-surface stratigraphy offshore of the Elizabeth Islands in MA, and these navigation data can help spatially correlate the seismic-reflection profiles with other data in the GIS.
Are there legal restrictions on access or use of the data?
