Abstract:
The U.S. Geological Survey has conducted geologic mapping to characterize the sea floor offshore of Massachusetts. 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 GeoTIFF (Tagged Image File Format) image shows shaded-relief multibeam bathymetry in Massachusetts Bay as grayscale at 10-m resolution.

Attribute_Accuracy:
Attribute_Accuracy_Report: There are no attributes associated with a GeoTIFF image.
Logical_Consistency_Report: Information unavailable from original metadata.
Completeness_Report:
The multibeam bathymetric data, on which this image is 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 would improve the sounding data and 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; roughly 30 - 50 cm within the study area.

Process_Description:
A suite of processing software (called SwathEd) (www.omg.unb.ca/~jhc/SwathEd.html), developed by the Ocean Mapping Group at the University of New Brunswick, Canada, was used to process and grid the multibeam bathymetric soundings and produce shaded-relief images. The metadata for the grids describes the processing steps applied to the navigation and bathymetric soundings. The following processing steps produced the image of shaded-relief bathymetry: 1. Create a 10-m grid of the bathymetric sounds for Massachusetts Bay using the SwathEd routine weigh_grid. Command line: weigh_grid -fresh_start -omg -tide -coeffs -mindep -2 -maxdep -800 -beam_mask -beam_weight -custom_weight EM1000_Weights -butter -power 2 -cutoff 20 -lambda 5 gridFile filename.merged 2. Create a shaded relief image of the bathymetry using SwathEd routine addSUN (sun elevation of 45 degrees from 350, vertically exaggerating 4 times). Command line: addSUN -elev 45 -azi350 -vert_exag 4.0 gridFile.r4 filename.shade 3. Use a two-point linear contrast stretch to enhance the shaded relief image: Command line: stretchacres -low 150 -high 200 -in filename.shade -out filename_shade.stretch 4. Convert each contrast-stretched shaded relief image from SwathEd format to a tiff file using the netpbm utilities (http://netpbm.sourceforge.net/): Command line: rawtopgm -headerskip 1024 image_width image_height filename_shade.stretch | pnmtotiff -none - > filename.tif 5. Create an ESRI world file (tfw) for the shaded relief tiff image for import to ArcView or ArcGIS. Copy bounding box and resolution information from the jview program output to the tfw file. Command line: jview filename_shade.stretch

Reprocessing to correct projection error An error in the UNB processing software that resulted in the multibeam observations not being properly projected onto a plane was discovered in 2003. These software errors were corrected and the data re-gridded.

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.). The source information was incomplete and had to be modified to meet the standard. 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.
