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, Coastal and Marine Geology Program, Woods Hole Science Center. 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 reserves, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30m 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/html/current_map.html>). This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. They were collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005.

Purpose:

The purpose of these data is to manage the locations and filenames of the 3,870 kms of raw bathymetric files collected using the SwathPlus bathymetric sonar and RESON Multibeam sonar in the Cape Ann to Salisbury Beach survey area.

Data_Quality_Information:

Logical_Consistency_Report:

SurveyID = 4015: Additional survey lines (gap fill lines) were run where data gaps exist in shallow water between the main survey lines (main scheme lines). Duplicate line names exist for short gap fill lines. In shallow areas where several adjacent short gap fill lines were required, the sonar operator would keep collecting data in between lines because there was not enough time to stop and start new line names at 8-10 knot survey speed.

Completeness_Report:

Main scheme and gap fill lines are included for the offshore area (SurveyID=4015) and does not include the cross lines run for junction analysis during the survey. Bathymetric tie lines for the nearshore area (SurveyID=5005) are included because they were collected along with the seismic profile lines offshore.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation for survey 04015 used Differential Global Positioning System (DGPS) signal from U.S. Coast Guard beacons. Navigation for survey 05005 used Real Time Kinematic (RTK) GPS from a base station established by USGS for this survey. Any horizontal offsets between bathymetric sonars and GPS receiver on both survey vessels were measured and corrected in the sonar setup.

Process_Step:

Process_Description:

SurveyID= 05005-Raw SwathPlus bathymetric sonar (*.SXR) data were unraveled (imported) to SwathEd multibeam processing software developed by the Ocean Mapping Group (OMG) at the University of New Brunswick (UNB) Canada. An ASCII navigation file is produced as part of the unravel process that records navigation fixes in decimal degrees every 10 seconds along the survey line. Each ASCII navigation file is run through the custom AWK script "ConvertSwathEdNav" (developed by USGS) that adds the Julian day, line file name, and reprojects the decimal degree coordinate to Universal Transverse Mercator (UTM Zone 19 WGS84) coordinates for each navigation record.

Process_Description:

SurveyID= 05005- This ASCII navigation text file is imported to ArcGIS (ver. 9.2 ) as an event theme using the "Add XY Data" feature in the Tools menu, and then converted to a point shapefile using the context menu "Export Data". This point shapefile is converted to a polyline shapefile using custom tool developed by USGS that retains the Julian day and line name attributes. Finally the polyline shapefile is converted to a file geodatabase feature class and the DeviceID, SurveyID, and VesselID attributes are calculated to match the Arc Marine Data Model schema.

Process_Description:

SurveyID = 4015- Raw RESON 8101 multibeam echo sounder files in Generic Sensor Format (GSF) were imported to CARIS HIPS/SIPS (ver. 6.1). The CARIS project used the Universal Transverse Mercator coordinate system (UTM) Zone 19 WGS84. Line files were converted from HIPS to CARIS Map using the export function in the main "File" menu. Resulting CARIS Map (*.des) file was converted to ESRI Shapefile using the CARIS conversion utility (ver. 2.0). The line name attribute and UTM projection for each line was retained as part of the CARIS Map to shapefile conversion. The resulting polyline shapefile was converted to ArcGIS 9.2 file geodatabase feature class and the DeviceID, VesselID, and SurveyID attributes were calculated to match the Arc Marine Data Model schema.
