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/html/current_map.html>). The data collected in the study area located in Vineyard Sound Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection). The data were collected during three separate surveys conducted between 2009 and 2011and cover approximately 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 the Woods Hole Coastal and Marine Science Center Field Activity webpage:

Purpose:
The purpose of these data is to manage the location and filenames of the approximately 3,920 kilometers of raw bathymetry files collected using a Systems Engineering and Assessment (SEA) Ltd. SWATHplus-M interferometric sonar within the Vineyard Sound survey area.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: All attributes were checked in a consistent manner.
Logical_Consistency_Report:
Any spurious navigation points were removed during processing before the polyline was produced. Duplicate names may exist for the "LineName" attribute; however further querying the data by the "Survey", "Vessel", or "JulDay" attributes will produce a unique trackline for each record in this spatial dataset.
Completeness_Report:
Only the subsets of interferometric bathymetric sonar collected during field activities 2009-002-FA, 2010-004-FA, and 2011-004-FA that are within the Vineyard Sound survey area have been included in this spatial dataset. This shapefile includes all bathymetric tracklines collected in the Vineyard Sound survey area, however, not all of these tracklines were included in the final bathymetric grid published in this same report. Data collected along transit lines, east-west seismic tie lines, and other lines of poor quality were excluded from this grid. The following survey lines from this shapefile are not included in the vs_bath_5m grid published in this report: 2009-002-FA L63f1, L64f1, L74f1 2010-004-FA Patch2_1- Patch2_7, TIE8F1-TIE20F1, L286F1 2011-004-FA: Patch1-Patch7, L130F1, TIE1, TIE8-TIE15
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Coordinates from the Differential Global Positioning System (DGPS) was used record the horizontal position of the SWATHplus transducers during all three surveys. Differential corrections were transmitted to the survey vessel by cellular modem and VHF radio from the base station established at the USGS Marine Operations Facility in Falmouth, MA. A conservative estimate of horizontal positional accuracy is estimated at 10 m, although the horizontal navigation system used for these surveys (DGPS) can be as reliable as +/- 2m. NAVIGATION DETAILS: Navigation was acquired with a Coda Octopus F180 Differential Global Positioning System, plus Wide Area Augmentation System (DGPS + WAAS) accurate to +/- one to two meters horizontal mounted directly above the sonar transducers. All DGPS data were referenced to WGS84. The horizontal accuracy of these tracklines is assumed to be within the accuracy of the DGPS. A conservative estimate of positional accuracy is +/- 2 meters.

SONAR CONFIGURATION: Bathymetry data were acquired using a Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar operating at 234 kHz. Survey lines were run at an average speed of 5 knots and were spaced 100 m apart to obtain overlapping swaths of data and full coverage of the seafloor. During USGS field activities 2009-002-FA and 2010-004-FA, the SWATHplus transducers were mounted on a rigid pole on the starboard side of the M/V Megan T. Miller, about 2.46 m below the waterline. The DGPS antenna was mounted on top of the same pole 4.3 m above the waterline of the vessel. During USGS field activities 2011-004-FA, the SWATHplus transducers were mounted on a rigid pole on the starboard side of the M/V Scarlett Isabella, about 2.17 m below the waterline. The DGPS antennae was mounted on top of the same pole 4.6 m above the waterline of the vessel.

Process_Description:
Step 1. Raw to Processed Conversion: Survey navigation information is stored within each SWATHplus raw (sxr) data file. Each raw SWATHplus bathymetric sonar file (sxr) was converted to a SWATHplus processed file (sxp) using SEA SWATHplus Swath Processor (ver. 3.06 for 2009-004_FA; 3.07 for 2010-004-FA, 2011-004-FA).

Step 2.CARIS Processing: A new Computer Aided Resource Information System (CARIS) Hydrographic Information Processing System (HIPS) project (ver. 6.1 and 7.1) was created for each of the three surveys with projection information set to Universal Transverse Mercator (UTM) Zone 19, WGS84. Each SWATHplus processed file (sxp) was imported to the new CARIS project using the Import/Conversion Wizard. Navigation was checked and edited as needed using the Navigation Editor tool.

Step 3.Convert CARIS Tracklines to Shapefile: The tracklines in the separate CARIS projects were converted to an ESRI shapefile during a two-step process. First the CARIS tracklines were converted to a CARIS Map using the export tool within HIPS "HIPS to CARIS Map" Input File: All lines in the HIPS Project. The "Export Track Lines" option was checked Output File: "SurveyName"BathTrks.des Second, using CARIS Conversion Utility (ver. 2.1) The CARIS Map (.des) file was converted to a ESRI shapefile. During the conversion the name of the HIPS line file "Source" and "Date was carried over to the shapefile. Input File: "SurveyName"BathTrks.des Output File: "SurveyName"BathTrks.shp

Step 4. Add Attributes to each shapefile: The following string attributes were added to each of the three trackline shapefiles by using the context menu within ArcGIS 9.3. "LineName", "Survey", "Vessel" "JulDay" The LineName was derived from the "Source" attribute, and JulDay was derived from the "Day" attribute. In addition the "Length_km" attribute (double) was added to each shapefile. The length of each polyline in kilometers was calculated using the context menu "Calculate Geometry" within ArcMap.

Step 5. Merge and Project Shapefiles from UTM 19 WGS84, to WGS84 Coordinate System: The three separate bathymetric tracklines from each of the three surveys (SurveyNameBathTrks.shp) were merged into on shapefile (VS_BathymetryTracklines.shp) using the "Merge" Tool in ArcToolbox (ver 9.3). During the merge process the input coordinate system was UTM Zone 19, WGS84, and the output coordinate system was the Geographic Coordinate System (GCS), WGS84.
