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 and PNG images and SEG-Y data files. In order to scan the lines, some of the paper records were cut and scanned in sections. These sections are labeled with lower-case letters and differ from the names of lines in the logbook. Some SEG-Y files were further divided in order for each file to contain continuous data collected at the same ship speed; these line segments have been labeled _1, _2, or _3 after the section label. Navigation data were converted from LORAN-C time delays to latitudes and longitudes that 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 NEECHO during a 1980 geophysical cruise in western Rhode Island Sound. The seismic data provide useful information about the framework geology in this region. This metadata describes the PNG files as a whole.

Process_Step: Process_Description: Original analog seismic records of cruise NECH80-1 were obtained using a towed EG&G Uniboom system 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. Process_Date: 1980 Process_Step: 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, n80_102Ac.tif signifies the cruise as R/V NEECHO in 1980 (NECH80-1), line 02A, section c, and TIFF format. Capitalized letters are part of the original line number, as recorded in the logbook and on the seismic line.

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, _2, or _3 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/2009/1002/html/wris_prof.html) in order to see field notes related to data acquisition and weather conditions, which were written directly on the paper records.

This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. Fixed the date format in the time period of content and source contribution. Online link was added to a cross-reference. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
