Description:
Abstract:
These data are high-resolution acoustic backscatter measurements of the seafloor offshore of Massachusetts, from Nahant to Gloucester. Approximately 127 km2 of the inner shelf were mapped in the nearshore region between the 10m and 40-m isobath.
Purpose:
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. High resolution bathymetry, backscatter intensity, and seismic profile data were collected over 127 km2 area covering a portion of the South Essex Ocean Sanctuary to characterize the surface and subsurface of the seafloor for regional geologic framework investigations. Backscatter data were collected during two different surveys. Survey RAFA03007 began Monday, 22 Sep 2003 (JD267) and ended on Tuesday, 14 Oct 2003 (JD287). RAFA04002 began 17 Apr 2004 (JD 108) and ended on 2 May 2004 (JD123).

Vertical_Positional_Accuracy_Report:
The RTK corrected signal was sent from a USGS survey-specific base station at the lighthouse on Eastern Point Lighthouse. The base station occupied a DMA monument, however, the x, & y positions were calculated for that location using a 3 day average of 12 hour data sets using the Online Positioning User Service (OPUS, National Geodetic Survey) solution. Sidescan tow fish layback was 6 meters.

Process_Step:
Process_Description:
The positional accuracy of the final 1m resolution mosaic was increased by further georeferrencing (rubber sheeting) to the submetrix interferometric sonar backscatter mosaic. The interferometric data has higher order positional accuracy than the towed sidescan-sonar because the GPS antenna is mounted on top of the same pole as the interferometric sonar and there is no inacuracies from towfish layback. The rubber sheeting was calculated in ArcGIS with the Georefferencing.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). Online linkages were fixed (some needed to point to pubs.usgs.gov). None of the original process steps had process dates, so those were set to "unknown". Time period of content date format was fixed. 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.
