- Abstract:
-
During 1980, the U.S. Geological Survey (USGS) conducted a seismic-reflection survey utilizing Uniboom seismics in southern Rhode Island Sound aboard the Research Vessel Asterias. This cruise totalled 3 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 set contains grayscale seismic-reflection images in PNG format from the seismic-reflection data set collected aboard the R/V Asterias during a 1980 geophysical cruise in southern Rhode Island Sound. These images correspond to the SEG-Y files. The seismic data can be used to provide useful information about the framework geology in this region. This metadata describes the PNG files as a whole.

Original seismic records of cruise AST-80-6B were obtained using a towed EG&G Uniboom system, towed 15 m astern of the vessel, with a half-second fire rate. The signal was amplified and filtered to a 400- to 4000-Hz bandpass. The seismic data have 1- to 2-m resolution. Seismic data were printed on EPC recorders at a quarter-second sweep rate. The ship speed averaged 5 knots. Shipboard systems include: EG&G Uniboom Catamaran with mounted transducer, EG&G Trigger-Capacitor Bank, EPC Seismic Recorder (4100 series), Teledyne Exploration Seismic Amplifier (Model 300), Del Norte Hydrophone Streamer (30 element), Krohn-Hite Band Pass Filter, Northstar 6000 Loran C Receiver and Repeater.

- Process_Description:
-
Original seismic records were scanned at 300 dpi, 24-bit grayscale on an Ideal Contex Crystal TX 40 scanner using Ideal ScanOS version 2.5.4 software and saved as TIFFs, after being roughly rotated and cropped. Some seismic lines were too long to scan at once and were cut into sections, other lines were collected in sections. These sections are noted in the file names with lower-case letters after the line number. For instance, a80_607a_1.png signifies the cruise as R/V Asterias in 1980 (AST-80-6B), line 7, section a, SEG-Y segment _1 and PNG format.

Grayscale TIFFs were further processed in Adobe Photoshop CS2 in order to aid in creating the SEG-Y files. These TIFF images were rotated so they were nearly perfectly horizontal and cropped to start and end shots with known positions and saved as PNG files. Seismic-reflection profiles that had noted changes in ship speed or places where recording stopped for belt changes were split into segments, so each file was obtained at roughly the same speed. These segments are labeled with _1 or _2 after the section, thus the file names differ slightly from the line names as used in the logbook. Since PNG images were clipped in the process of making SEG-Y files, users are encouraged to view the TIFF images available in this report (<https://pubs.usgs.gov/of/2009/1003/html/sris_prof.html>) in order to see field notes related to data acquisition and weather conditions, which were written directly on the paper records.
