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 seafloor 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 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (https://woodshole.er.usgs.gov/project-pages/coastal_mass/). The data collected in this study area are located in both Buzzards Bay and Vineyard Sound and are primarily in the shallow water areas around the eastern Elizabeth Islands and Martha's Vineyard, Massachusetts. The data include high resolution bathymetry, acoustic-backscatter intensity, sound velocity in water, seismic-reflection profiles, and navigation data. These data were collected during several cruises between 2007 and 2011 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, a boomer source and Geometrics 8-channel GeoEel streamer, a Knudsen 3200 subbottom profiling system, and 4 GPS antennae. More information about the cruises conducted as part of the project: Geologic Mapping of the Seafloor Offshore of Massachusetts can be found on the Woods Hole Coastal and Marine Science Center Field Activity webpages: https://cmgds.marine.usgs.gov/fan_info.php?fan=2011-013-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2009-068-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2007-039-FA, https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-100-FA, and https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-047-FA. Purpose: PNG images of each seismic profile were generated in order to incorporate images of the seismic data into Geographic Information System (GIS) projects and data archives. These PNG images represent approximately 170 km of multichannel boomer seismic data collected with a GeoAcoustics boomer source and Geometrics 8-channel GeoEel streamer from July 7 to 19, 2010. This format is universal and yields an easily browseable pictorial view of the seismic profiles. Each profile image is hotlinked to its corresponding trackline navigation contained within a polyline shapefile, and even 500 trace locations are available in a point shapefile. All of these data are available in a Esri ArcMap project, as well as separate .zip archives.

Quality control was conducted during processing. File naming for Julian days 193 to 194 is x_yz.png, where x is the Julian Day and y is the time of day in hours, and z is the time of day in minutes with an implied decimal value of one. Note the time was based on system time and not GPS time for Julian days 193 to 194. A time server was installed for Julian days 198 to 200 and system time was synced with GPS time. For Julian days 198 to 200 file names is x_lyfz.png where x is Julian day, y is the survey line number, and z is the file number within the survey line. Completeness_Report: No data were collected on Julian days 195 to 197 due to weather conditions. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The navigation for these data were acquired with an Communications Systems International (CSI), Inc. LGBX Pro Differential Global Positioning System (DGPS) receiver and an antenna mounted on the cabin of the R/V Rafael. All DGPS data are referenced to WGS84. The Geometrics CNT-1 acquisition software logged the navigation coordinates (in arc seconds) to individual trace headers. Layback distance between the CSI antenna and the source and receiver were calculated in postprocessing. The resulting horizontal accuracy is assumed to be +/- 2 m; however, inaccuracies likely exceed this value due to uncertainty of azimuths calculated in the layback correction.

The Applied Acoustics boomer source was towed on the starboard side of the RV Rafael at a depth of 0.5 meters, 10 meters aft of the GPS antenna, and was fired at a power level of 100 joules at 0.5 second intervals for the first line and then at 1-second intervals thereafter with trace lengths of 250 milliseconds. The Geometrics GeoEel, eight-channel liquid filled digital streamer was towed from the port side of the vessel at a depth of about 1 meter, and the center of the first channel of the active section was 22 meters aft of the boomer source. The streamer had a group interval of 3.125 meters (50 meter active section) connected to Geometrics Streamer Power Supply Unit (SPSU). Data acquired in Geometrics SEG-D format on Windows PC controller system using Geometrics CNT-1 software. The sample interval was 0.25 ms. Process_Step: Process_Description: A SIOSEIS seismic processing software script was used as follows: the raw SEG-D shot files were read with the process SEGDDIN specifying geometrics format; for Julian days 193 to 194, the SEG-D files were read, the process HEADER was used to insert time of day into the SEG-Y header based on the start and end times recorded in the HYPACK files and what was entered in the survey log and SEG-Y files were written.; For JD 193 to 194 these SEG-Y files were input to the remaining steps. For all other days, the SEG-D files were used as input. the process GEOM was used to describe the shot and streamer geometries and to calculate the reflection point (CDP) numbers used to gather (sort traces by CDP) the seismic line; the process GEOM was used to set the shot-receiver distance into the trace header of every trace; GEOM type 6 was specified (because positions were absent or bad in the header), which computes a distance from last shot (DFLS) for each shot based on the shot time in the header and the navigation from an ASCII file containing time and position; the ASCII shot navigation file was derived from the HYPACK navigation data and merged with shot point files with the Unix join command; a normal move out (NMO) applied a travel time correction to each trace based on offset and a velocity of 1500 m/s; process GATHER was used to sort the shot order traces into traces sorted by the CDP numbers computed by the process GEOM; lastly, the CDP trace gathers were written with the process DISKOX in SEG-Y rev. 1, IEEE floating point format.

The process DISKIN read the CDP sorted SEG-Y file and renumbered CDP starting at one and incremented CDP number by one. The process STACK was used to sum traces, compute the average amplitude for each trace sample, and write the computed samples to one trace. The trace header values of the first trace in the gather were used for the stacked trace. The process FILTER applied a zero-phase bandpass frequency domain filter between 600 and 2000 Hz with a slope of 48 decibel per octave slope. The process AGC applied an automatic gain control (AGC) with a window length of 5 ms. The computed multiplier for each AGC window was reduced by fifty percent. Lastly, the processed stacked traces were written to disk with the process DISKOX in SEG-Y rev. 1 , IEEE floating point format.

All images were created with a horizontal scale of 60 traces per inch. Images were plotted within a constant 18-inch vertical window of 180 milliseconds (Two-Way Travel Time) duration. The Postscript images were then converted with ImageMagick (version 6.8.7-2) to PNG format at 200 dpi.

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. Added the DOI link in the Identification section - both as the first link and as part of the Larger Work citation. Fixed the publication date and also the Larger Work citation title to match what is available online. Updated the link to the project page in the abstract as well as the field activity links. The source information was incomplete and had to be modified to meet the standard. Fixed a link in the distribution section. 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.
