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 (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHSC). 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 resources, 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 is the spatial dataset for the Red Brook Harbor survey area within Buzzards Bay, Massachusetts. These data are the results of a high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples and bottom photographs) survey, conducted in 2009.
In addition to inclusion within the USGS-CZM geologic mapping effort, these Red Brook Harbor data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system. (<http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-018-FA>)
Purpose:
This dataset contains shot point navigation at even 500 shot intervals for approximately 240 km of Knudsen 3202 chirp seismic-reflection data collected by the U.S. Geological Survey during Woods Hole Science Center cruise 09018 offshore of Massachusetts within Red Brook Harbor. This information can help spatially correlate the seismic-reflection profiles with other data in the GIS.

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 'IMAGENAME'. No duplicates exist.

Sections of tracklines where navigation was recorded but no seismic data were logged are not included.

Horizontal_Positional_Accuracy_Report:
Differential Global Positioning System (DGPS) navigation data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro receiver. Navigation data were sent to the Knudsen SounderSuite acquisition application, which logged the coordinates to individual trace headers in the Society of Exploration Geophysicists Y (SEG-Y) Revision 1 format (Norris and Faichney, 2002). A 2 m horizontal offset between the seismic transducers and the DGPS receiver was not accounted for during data acquisition, and resulting positional accuracy is assumed to be better than 10 m.

Chirp seismic data were collected using a dual frequency (3.5 and 200 kHz) Knudsen Engineering Limited (KEL) Chirp 3202 system (Knudsen Engineering Limited, 2009) with transducers mounted on a rigid pole on the starboard side of the R/V Rafael of Woods Hole, MA. Knudsen SounderSuite seismic acquisition software was used to control the Chirp 3202 system, digitally log trace data in the Society of Exploration Geophysicists Y (SEG-Y) Revision 1 format (Norris and Faichney), and record DGPS navigation coordinates to the SEG-Y trace headers in arc seconds. The transducer draft was 0.5 m below the water surface, and the draft offset was accounted for during data acquisition. Navigation coordinates and water depths from the 200-kHz channel were logged together in ASCII formatted files for each survey line. During Julian days 271 - 287 data were acquired at a peak frequency of 3.5 kHz, a 0.25 or 0.2 second fire rate (4 or 5 shots per second), a 38 microsecond sample interval, and record lengths between 26 and 130 milliseconds. During Julian days 288 - 296 data were acquired at a peak frequency of 5.0 kHz, a .25 second fire rate, a 36 microsecond sample interval, and a 66 millisecond record length. A total of 240 km of seismic data were collected. Unique shot point locations are provided in file RB_SeismicShot_unique.csv, in the zip-compressed package for shapefile RB_SeismicTracklines.shp.
Process_Step:
Process_Description:
A C-shell script was executed that called on Seismic Unix (version 4.1) to read the SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, including shot number, longitude, latitude, year, Julian day, and time of day (UTC) to ASCII text files for each survey line. Files for data collected during Julian days 271-282, 288, and 294 were filtered using AWK (no version) to save records for the first and last shots, and shots at unique longitude/latitude positions in between. No navigation was recorded to the SEG-Y trace headers of all lines collected during Julian days 287 and 295, and portions of days 272 (l18f1_001) and 296 (l183f1_001 - l190f1_010), so separately logged 1 Hz DGPS ASCII navigation needed to be merged with the remaining information extracted from the trace headers. This was accomplished using an alternate AWK filter to save shot records for the first and last shots, the first shot recorded at each second, and shots numbers evenly divisible by 500. The VIM (version 7.2.108) text editor was then used to create a new field in each navigation and trace header text file that combined Julian day and UTC time. Finally, using the newly created field as the 'join' field, the unix JOIN (no version) command was used to merge coordinates from the navigation text file with corresponding shot records in each trace header file based on this Julian day time field. Geographic coordinates (WGS84) were converted to UTM zone 19 coordinates (WGS84) using Proj (version 4.6.0), and added to the text files in two new columns. VIM was used to add three additional columns to the text files containing the Woods Hole Coastal and Marine Science Center field activity number (SURVEYID), the device used to record the data (DEVICEID), and the vessel used for the survey (VEHICLEID).

Process_Description:
An additional AWK filter was applied to each file created in the previous step to extract trace header records containing the first and last shots, and shots evenly divisible by 500 for each survey line. 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\seisimage' directory.
