Edition: 1.0 Series_Information: Series_Name: Open-File Report Issue_Identification: 2007-1373 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2007/1373/ Description: Abstract: These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole Science Center. Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine reserves, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports <(http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html>). This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. The data collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005. Seismic profile data, sediment samples and bottom photography were also collected in 2005. Purpose: This data set contains trackline navigation for approximately 1100 km of EdgeTech 512i chirp seismic-reflection data collected by the U.S. Geological Survey during a 2005 cruise offshore of Massachusetts between Cape Ann and Salisbury Beach.

Logical_Consistency_Report: Any spurious data points were removed during processing. For each seismic trackline there is one seismic-profile image that is hyperlinked by the field 'Image'. No duplicates exist. Completeness_Report: Sections of tracklines where navigation was recorded but no seismic data were logged are not included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The SB-0512i was towed approximately 10 m astern and approximately 3 m below the sea surface. RTK-GPS navigation was obtained from the receiver mounted above the interferometric sonar head, but seismic towfish layback was not accounted for. The layback of the towfish adds additional uncertainty due to changes in angle and scope of the tow cable in response to sea state and vessel speed. Based upon horizontal offsets between the fish and GPS receiver, GPS accuracies, and fish motion behind the vessel, the resulting positional accuracy is assumed to be ± 20 m.

Source_Citation_Abbreviation: Raw data Source_Contribution: Seismic-reflection data acquisition at sea (2005): Chirp seismic data were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz) on the R/V Connecticut of Groton, CT. Delph Seismic+Plus acquisition software (Triton Elics International Inc.) was used to control the Geo-Star topside unit and digitally log trace data in the SEG-Y rev. 1 standard format. Data were acquired using a 0.25-s shot rate, a 9-ms pulse length, and a 0.5 to 6 kHz frequency sweep. Trace lengths were adjusted to account for changes in water depth, and consequently ranged between 100 and 200 ms. Tracklines are spaced between 100 and 1500 m apart in the shore parallel direction and about 1 km apart in the shore perpendicular direction. Process_Step: Process_Description: A script was run that used Seismic Unix (version 4.1) to read the SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, which included shot number, longitude, latitude, year, Julian day, and time of day (UTC). Geographic coordinates were converted to UTM zone 19 coordinates using Proj (version 4.6.0). Before saving the header information to a text file, the data were filtered using AWK (no version) to save only unique shot point locations. In addition, a separate text file containing even 500 shot intervals was saved. The 500 shot text file maintains the start and end shots, which may not necessarily be unique fixes. A 500 shot interval was chosen because it corresponds to the annotation interval provided along the top of the seismic-reflection profile JPEG images, which are included in the 'GIS\hyperlink_images' folder.

During import into the file geodatabase, point positions were projected to meters, UTM, Zone 19, WGS84.

The 'LineName' field was used to define which points were used to generate each polyline feature. Using Xtools Pro for ArcGIS desktop (version 4.1.0), the length of each polyline segment was calculated and included in two new attribute fields, 'Length' and 'Shape_Leng', specifying UTM, Zone 19 N, WGS84 kilometers and meters, respectively. Prior to importing a copy of the polyline shapefile into the file geodatabase to create a file geodatabase feature class, the 'Shape_Leng' attribute field was deleted because it was automatically replaced and recalculated with identical name and units (meters); During import into the file geodatabase, polyline features were projected to meters, UTM, Zone 19, WGS84.

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. The source citation information is inferred from other information in the metadata and was not part of the original metadata file. Other minor edits were probably performed (title, publisher, publication place, etc.). 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.
