Description:
Abstract:
During 1975, the U.S. Geological Survey (USGS) conducted a seismic-reflection survey utilizing Uniboom seismics in eastern Rhode Island Sound aboard the Research Vessel Asterias. 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 data file contains the 1-minute shot point navigation collected aboard the R/V Asterias during a 1975 geophysical cruise in eastern Rhode Island Sound. It is meant to accompany the SEG-Y files. 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.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute data were recorded by the science party and entered and checked by the compilers in a consistent manner.
Logical_Consistency_Report: The layers were edited and processed in a consistent manner.
Completeness_Report:
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). 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 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).

An AWK script was used to reformat the text file as right justified fields with space delimiters in the order Unique Line ID, shot number, easting, and northing, in order to generate a format ready to import into the seismic interpretation package, Landmark Graphics, SeisWorks. The easting and northing values are rounded to the nearest meter.
