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/). 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: JPEG images of each seismic profile were generated in order to incorporate images of the seismic profiles into Geographic Information System (GIS) projects and data archives utilizing HTML. The JPEG images represent 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. Each profile image is hotlinked to its corresponding trackline navigation contained within the ESRI polyline shapefile 'RB_SeismicTracklines.shp'. Even 500 shot index markers along the top of the JPEG images correlate to the positions of 500 shot intervals within the ESRI point shapefile 'RB_SeismicShot_500.shp'.

Series_Information: Series_Name: Open-File Report Issue_Identification: 2009-1072 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2009/1072/ Data_Quality_Information: Logical_Consistency_Report: Processed seismic data were converted to JPEG format for ease of seismic trace display. Quality control was conducted during processing. Changes in water depth, bottom type, and acquisition parameters during the survey caused significant variability in seismic trace amplitudes and subsurface penetration. Profiles in shallow water areas near the inner harbor experienced the most detrimental effects. Data quality generally improved as the survey progressed into the relatively deeper water of the outer harbor. Completeness_Report: One JPEG image exists for each seismic profile identified in the "IMAGENAME' attribute field of the shapefile 'RB_SeismicTrackline.shp' located in the directory 'http://pubs.usgs.gov/of/2010/1091/GIS/shapefile/' Positional_Accuracy: Horizontal_Positional_Accuracy: 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.

Source_Contribution: Chirp seismic data were collected using a dual frequency (3.5 and 200 kHz) Knudsen Engineering Limited (KEL) Chirp 3202 system 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. Process_Step: Process_Description: An executable C-shell script called on SIOSEIS (version 2007.8) to 1) mute water column portions of Knudsen 3202 seismic traces using the water depths recorded in the 200kHz channel; 2)apply gain and automatic gain control functions to the traces; and 3) write the resulting traces to new "mute_gain" SEG-Y files, which were used for creation of JPEG browse images and digital interpretation.

All images were created with a horizontal scale of 100 traces per inch. The profiles contain 50 milliseconds of Two-Way Travel Time within an 12-inch vertical window, yielding 4.2 milliseconds per inch. Postscript images were converted to JPEG format using ImageMagick (version 5.5.6).

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.). Fixed URL in abstract. The source information was incomplete and had to be modified to meet the standard. The link to the data in the Distribution_Information section had to be fixed. 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.
