This cruise totalled 8 survey days. Data from this survey were recorded in analog form and archived at the USGS. Due to 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 ship-track navigation collected aboard the R/V Asterias during a 1975 geophysical cruise in eastern Rhode Island Sound and corresponds to a75_6_segylines.shp. 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 can be used to 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: Navigation points are spaced at 1-minute intervals and at course changes or line events (start/end of line). Continuous navigation is not available. The logbook navigation for two points in the survey was determined to be incorrect and has been excluded from the data set (line 11b time 1945 and line 14 time 815). 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 9930 U.S. East Coast chain and recorded time delays from Cape Race, Newfoundland (X) and Dana, Ind. (Z) slave transmitters. Absolute accuracy is 185 to 463 m based on http://www.navcen.uscg.gov/loran/handbook/h-book.htm (see Chapter III).
