The mapping was carried out using a Simrad Subsea EM 1000 Multibeam Echo Sounder on the Frederick G. Creed on four cruises conducted between 1994 and 1998. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick. The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) project that presents images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys that will serve the needs of research, management and the public. Purpose: This shapefile shows sea floor bathymetry as contours at 10-meter intervals in the area of multibeam data in Massachusetts Bay. The contours were derived from a 30-meter resolution ESRI grid of multibeam data (mb_bathy30m), smoothed over a 9 cell by 9 cell rectangle using the Focalmedian routine. This smoothing produces contours appropriate for display at a scale of 1:125,000 (used for USGS Map I-2734).

Logical_Consistency_Report: These data are logically consistent. Completeness_Report: The multibeam bathymetric data, on which these contours are based, were corrected for tidal elevation during the survey using sea level measured at the NOAA Boston tide gage. This assumes that the tidal elevation and phase are the same as Boston across the survey area. Further processing to correct for the spatial and temporal changes in tidal elevation across the survey area may be undertaken at a later time. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: These data were navigated with a Differential Global Positioning System (DGPS); they are accurate to +/- 3 meters, horizontally. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: These data have been corrected for vessel motion (roll, pitch, heave, yaw) and tidal offsets, and referenced to mean lower low water. The theoretical vertical resolution of the Simrad EM-1000 multibeam echosounder is 1 % of water depth, approximately 0.3 - 1.0 m within the study area.

Process_Step: Process_Description: Bathymetric contours at 10-m intervals were created from a 30-m grid of multibeam bathymetry using the "latticecontour" routine. The 30-m grid was smoothed over a 9-cell by 9-cell rectangle using the "focalmedian" function in ARCGRID. These contours were converted to a shapefile (geographic projection) in ArcGIS.

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.). 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.
