Description:
Abstract: These data were collected under a cooperative agreement between 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 (WHCMSC). 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, https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-047-FA.
Purpose: CDP navigation at intervals of 500 and beginning and ending CDP values for each seismic profile were generated in order to incorporate the seismic data into Geographic Information System (GIS) projects and data archives utilizing HTML. These CDP navigation data represent approximately 140 km of multichannel boomer seismic data collected with a GeoAcoustics boomer source and Geometrics 8-channel GeoEel streamer.

Data_Quality_Information:
Logical_Consistency_Report: Processed seismic CDP navigation data were generated for inclusion in a GIS. Quality control was conducted during processing and points were checked to make sure they were viable fixes. File naming for Julian days 193 to 194 is x_yz, 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 where x is Julian day, y is the survey line number, and z is the file number within the survey line.
Completeness_Report: This shapefile represents the 500 CDP interval and start and end point navigation for all the seismic lines collected on this cruise. 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 arcseconds) 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.

Source_Contribution: Approximately 170 km of high-resolution multichannel boomer seismic-reflection profiles were collected. The Applied Acoustics boomer source was towed on the starboard side of the RV Rafael, 10 meters aft of the GPS antenna, and was fired at a power level of 100 joules at 1-second intervals with trace lengths of 250 milliseconds and 1000 samples per trace. The Geometrics GeoEel, eight-channel liquid filled digital streamer was towed from the port side of the vessel, 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 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 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; 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 in to 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.

Process_Step:
Process_Description: SIOSEIS script was used to stack the CDP gathers, apply a bandpass filter and automatic gain control. 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.

Process_Step:
Process_Description: A Seismic Unix script was used to read the trace headers of the stacked SEG-Y files and write CDP, source X and Y, year, day, hour minute, seconds only where the original channel number was equal to one (the channel closest to the source). Some CDP gathers did not contain a trace with channel one in the header and were eliminated. The coordinates represent the position of the GPS antenna, which has a constant offset of 10 meters to the source. The source to receiver offset was 22 meters. Half the distance between source and receiver represents the location of the common reflection point. A layback correction of 21 meters was applied to the navigation using an AWK script written by Wayne Baldwin, USGS. An AWK script was used to format the trace navigation with corrected layback positions in a comma delimited file.

Process_Step:
Process_Description: Using ArcToolbox, Linear Referencing Tools, a CDP navigation file was created with points for CDP at even intervals of 500 and with start and end CDP values. First, Create Routes was used to create a polyline calibrated shapefile using the Line field as the Route Identifier and Length as the Measure Source. Calibrate Routes used the output from Create Routes with Line as the Route Identifier Field and the CDP point file for all unique fixes described in process step 4. The Point Identifier Field was Line, the Measured Field was CDP and the Measure Calculation Method was Measures. This created a calibrated polyline shapefile. Hatches were added at the beginning and end of each line, as well as at 500 CDP spacing. This was done in ArcMap 9.3 by opening the layer properties and selecting the Hatches tab. Create a hatch interval of 500 for the Hatch Class, then for Hatch Def(1) place a marker hatch every 1 hatch interval. From the Hatch Class -- Add a Hatch Definition - Add End Hatch Definition and set these to a marker Hatch. By displaying the labels for both Hatch Definitions, a quick comparison between the hatches and the unique trace navigation makes sure things are lining up right. Within ArcMap 9.3 - by going to Tools - Customize - Commands and scrolling down to the Category "Linear Referencing", the icon for the command "Convert Hatches to Graphics can be added to a toolbar. Once this is done, that tool can be used to convert the hatches to graphics. The graphics were converted to a shapefile using XTools Pro version 7.1. XTools Pro - Feature Conversions - Convert Graphics to Shapes. ArcToolbox - Linear Referencing Tools - Locate Features Along Route used the shapefile converted from graphics with input route features; Lines as Route Identifier Field, and 5 meters as Search Radius. A DBF file was output with Line as Route Identifier Field, point as Event Type, and CDP as Measure Field. The rest of options at default were checked. Using ArcMap 9.3 - ArcToolbox - Linear Referencing Tools - Make Route Event Layer to create an event feature. The input used the following parameters: input route features: the output from Calibrate Routes was the Input Route Features; Lines was the Route Identifier Field , input event table; the output from Locate Features Along Route was used for the Input Event Table; Line was the Route Identifier Field; Point was the Event Type; CDP was the Measure Field. The rest of the option left at default values. The event layer was converted to a shapefile in ArcMap 9.3 by exporting the data (right mouse click on event layer, Data, Export Data) to a temporary shapefile. The temporary shapefile was sorted within ArcMap 9.3 using VAC Extras version 2.1 (an extension written by the USGS in Woods Hole) to sort the shapefile: VAC Extras - FeatConv - Table Sort with the CDP file sorted based on Line and CDP. Line was set as the primary sort field, ascending order. CDP was set as the secondary sort field - ascending order. Output to 2010-047-FA_Boomer_cdp500.shp. Finally, ArcToolbox was used to reproject from UTM projection to Geographic coordinate system.

Process_Description: Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. 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.
