Edition: 1.0 Geospatial_Data_Presentation_Form: raster digital data Series_Information: Series_Name: Open-File Report Issue_Identification: 2012-1006 Publication_Information: Publication_Place: Reston, VA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/of/2012/1006/ 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 of coastal Massachusetts, primarily in water depths of 3-30 meters deep. 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/). The data collected in the study area located in Vineyard Sound, Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection), and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during three separate surveys conducted between 2009 and 2011 (USGS-WHSC surveys 2009-002-FA, 2010-004-FA, and 2011-004-FA) and cover 340 square kilometers of the inner continental shelf. More information about the individual USGS surveys conducted as part of the Vineyard Sound project can be found on Woods Hole Coastal and Marine Science Center Field Activity webpages: 2009-002-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-002-FA 2010-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2010-004-FA 2011-004-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-004-FA Purpose: PNG 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 PNG images represent approximately 3800 km of EdgeTech SB-512i chirp seismic-reflection profiles collected within Vineyard Sound. Each profile image is hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile 'VS_SeismicTrackline.shp'. Even 500 shot index markers along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile 'VS_SeismicShot_500.shp'.

Source_Contribution: Seismic-reflection data acquisition 2009-002-FA: Chirp seismic data were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz), which was mounted on a catamaran and towed astern of the M/V Megan T. Miller. Chesapeake Technologies' SonarWiz (v.4.04.0031) seismic acquisition software was used to control the Geo-Star topside unit, digitally log trace data in the SEG-Y Rev. 1 format (IEEE floating point), and record GPS navigation coordinates to the SEG-Y trace headers (in arc seconds of Latitude and Longitude, multiplied by a scalar of 100). Data were acquired using a 0.12-s shot rate, a 20-ms pulse length, and a 0.7 to 12 kHz frequency sweep. Traces were recorded in depth, assuming a constant sound velocity of 1500 m/s, with trace lengths of approximately 66 m (1250 samples/trace and .000053-s sample interval). Seismic-reflection data acquisition 2010-004-FA: Chirp seismic data were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz), which was mounted on a catamaran and towed astern of the M/V Megan T. Miller. Chesapeake Technologies' SonarWiz (v.4.04.0111) seismic acquisition software was used to control the Geo-Star topside unit, digitally log trace data in the SEG-Y Rev. 1 format (IEEE floating point), and record GPS navigation coordinates to the SEG-Y trace headers (in arc seconds of Latitude and Longitude, multiplied by a scalar of 100). Files l113f1 - l115f1 were acquired using a 0.25-s shot rate, a 5-ms pulse length, and a 0.5 to 8 kHz frequency sweep. Recorded trace lengths were approximately 200 ms (4340 samples/trace and .000046-s sample interval). The remaining files from Julian days 141 - 155 were acquired using a 0.25-s shot rate, a 50-ms pulse length, and a 0.5 to 4.5 kHz frequency sweep. Recorded trace lengths were approximately 199 ms (4328 samples/trace and .000046-s sample interval). Seismic-reflection data acquisition 2011-004-FA: Chirp seismic data were collected using an EdgeTech Geo-Star FSSB sub-bottom profiling system and an SB-0512i towfish (0.5-12 kHz), which was mounted on a catamaran and towed astern of the M/V Scarlett Isabella of Cape May, NJ. Chesapeake Technologies' SonarWiz (v.5.03.0016) seismic acquisition software was used to control the Geo-Star topside unit, digitally log trace data in the SEG-Y Rev. 1 format (IEEE floating point), and record GPS navigation coordinates to the SEG-Y trace headers (in arc seconds of Latitude and Longitude, multiplied by a scalar of 100). Data were acquired using a 0.25-s shot rate, a 5-ms pulse length, and a 0.5 to 8 kHz frequency sweep. Recorded trace lengths were approximately 200 ms (4340 samples/trace and .000046-s sample interval). Process_Step: Process_Description: SIOSEIS (version 2010.2.25) was used to read SEG-Y files, renumber shots starting from one, and write out new SEG-Y files. The original shot numbers, which were assigned by SonarWiz sequentially over the duration of an acquisition session despite SEG-Y file changes, are preserved in the raw SEG-Y data.

Two-way travel times (meters for 2009-002-FA, and milliseconds for 2010-004-FA) to the sea floor at each trace were recorded to ASCII text files.

Spurious seafloor values were edited for discrete traces through heads-up digitization of the Seisworks horizon, and corrected values were exported to a new ASCII text files.

SIOSEIS (version 2010.2.25) was used to convert the sample interval of 2009-002-FA seismic traces to time (0.000071 seconds). SIOSEIS was used to insert Seisworks corrected seafloor values into the SEG-Y trace headers (2009-002-FA and 2010-004-FA data), minimize the effect of sea surface heave using process 'swell' (2010-004-FA data only), mute water column data using the corrected seafloor values (2009-002-FA and 2010-004-FA data), apply time varying gain to trace data below the seafloor (a(i) = a(i) * (t-wbt) ** alpha, for t >= wbt; alpha=0.5 (2009-002-FA) or 1.5 (2010-004-FA); wbt=seafloor value), apply automatic gain control using a 10 ms window and 50 percent of the computed multiplier for each AGC window (2009-002-FA and 2010-004-FA), and write out new muted, gained, agc corrected SEG-Y files for creation of PNG browse images and digital interpretation.

All images were created with a horizontal scale of 200 traces per inch. The profiles contain 80 milliseconds of Two-Way Travel Time within an 12-inch vertical window, yielding approximately 7 milliseconds per inch. Postscript images were converted to PNG format using ImageMagick (version 6.6.1) The x-axis units of the images are shot number while the y-axis is two-way travel time in seconds.

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 the link to the appendix in the Identification_Information section. Fixed a link to the project page in the abstract. Fixed a link in the cross-reference section to the SEG-Y format documentation. The source information was incomplete and had to be modified to meet the standard. 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.
