Description:

Abstract:

This data set contains the sea floor topographic contours generated from a multibeam sonar survey of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts, an area of approximately 1100 square nautical miles. The Stellwagen Bank NMS Mapping Project is designed to provide detailed maps of the Stellwagen Bank region's environments and habitats and the first complete multibeam topographic and sea floor characterization maps of a significant region of the shallow EEZ. Data were collected on four cruises over a two year period from the fall of 1994 to the fall of 1996. The surveys were conducted aboard the Canadian Hydrographic Service vessel Frederick G. Creed, a SWATH (Small Waterplane Twin Hull) ship that surveys at speeds of up to 16 knots. The multibeam data were collected utilizing a Simrad Subsea EM 1000 Multibeam Echo Sounder (95 kHz) that is permanently installed in the hull of the Creed.

Purpose:

Development of interpretive seabed maps, sea floor imagery, and a GIS database that are accessible to scientists, policymakers, managers, and the general public.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The ship's position was determined with an accuracy of 10 m or better using a Magnavox 4200 geographic positioning system (GPS) receiver in conjunction with differential GPS corrections transmitted by U.S. Coast Guard radio beacons. Sound velocity information was updated during the day whenever the survey moved from one area to another. Tidal corrections based on NOAA's Boston tide gauge were used to reference depth data to mean lower low water. Sounding rates depend on water depth but vary from 2 to 4 per second in water depths less than 100 meters. Horizontal spatial resolution at these sounding rates is on the order of 10% of the water depth at 16 knots; however, vertical resolution is approximately 1% or better in the same depth range.

Logical_Consistency_Report:

No additional checks for topological consistency were performed on the data.

Completeness_Report:

The bathymetric data are displayed in real time on the Sun workstation using software designed and written by the Ocean Mapping Group, University of New Brunswick. This display allows data gaps to be identified during the survey and also gives a measure of the data quality.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Sounding rates depend on water depth but vary from 2 to 4 per second in water depths less than 100 meters. Horizontal spatial resolution at these sounding rates is on the order of 10% of the water depth at 16 knots; however, vertical resolution is approximately 1% or better in the same depth range.

Process_Step:

Process_Description:

The navigation and topographic data were both processed using SwathEd, a suite of bathymetric and multibeam software editing and display tools developed by Dr. John Hughes Clarke of the Ocean Mapping Group, University of New Brunswick (UNB). Tidal corrections were obtained from NOAA's Boston Tide Gauge (Station 8443970) and merged into the data set using UNB's tidal routines. The topographic information was converted into an ASCII text file containing lat, long, and depth fields, using a script created by Bill Danforth at the U.S. Geological Survey. The ASCII file was brought into Arc/Info, and a grid was generated and processed using ESRI's Arc/Info version 7.0.4 software. A point coverage containing depth values was created using the routine point-generate. The grid was created based on the depth values for each of the points using the command pointgrid. The grid was filtered with a 9 by 9 focalmedian filter. Contours were generated using latticecontour. All editing and edgematching was done by hand using arcedit.

Process_Date: unknown

Process_Step:

Process_Description:

The metadata was edited to remove errors as well as update some information. Edits include modifying the title to move the dataset name to the end of the title, adding the DOI link in the identification section, added the suggested citation, added supplemental information with link to the related field activity pages on CMGDS, added the USGS Thesaurus keywords, added keywords section with USGS persistent identifier as theme keyword, added online links to cross-references, replaced distribution liability with FSP statement, used a generic email address in metadata. The metadata date (20050822), but not the contact (except email and contact instructions) was updated. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent. Original edits on 20210816. An additional author name fix on 20210908. Links to the data were fixed with respect to case-sensitivity issues. (20230427)
