This cruise consisted of 2 legs totalling 8 survey days. Data from this survey were recorded in analog form and archived at the USGS. As a result of recent interest in the geology of Rhode Island Sound and in an effort to make the data more readily accessible while preserving the original paper records, the seismic data from this cruise were scanned and converted to TIFF images and SEG-Y data files. Navigation data were converted from LORAN-C time delays to latitudes and longitudes, which are available in ESRI shapefile format and as eastings and northings in space-delimited text format. Purpose: This GIS layer contains the 1-minute shotpoint navigation for seismic data 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.

Logical_Consistency_Report: The layers were edited and processed in a consistent manner. Completeness_Report: Complete information is provided for all navigation lines in the data set. Navigation points are spaced at 1-minute intervals and at course changes or line events (start/end of line). Continuous navigation is not available. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: All navigation was done by LORAN-C and was manually recorded. The cruise used the Group Repetition Interval 9960 Northeast U.S. chain and recorded time delays from Caribou, Maine (W) and Carolina Beach, N.C. (Y) slave transmitters. Absolute accuracy is 185 to 463 m based on http://www.navcen.uscg.gov/loran/handbook/h-book.htm (see Chapter III). Lineage: Source_Information: Source_Citation: Citation_Information: Originator: C.
