This GIS layer contains the ship-track navigation collected aboard the R/V Neecho during a 1980 geophysical cruise in western Rhode Island Sound. It is part of a digital version of a regional map showing the distribution of sub-bottom seismic profiles collected in Rhode Island Sound. The seismic data collected along these ship tracks provide useful information about the framework geology in this region.
