- 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 image shows shaded-relief multibeam bathymetry, colored by water depth, at 30-m resolution in Massachusetts Bay.

- Logical_Consistency_Report: These data are logically consistent.
- 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 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. However, we found that the working vertical resolution of the system is roughly +/- 50 cm for water depths of 30 - 50 meters based on comparisons of grids from multi-year surveys of the same area.

An image showing shaded relief bathymetry, colored by water depth, was created from the grayscale bathymetry tiff (mb_bathygs30m.tif) and the grayscale shaded relief tiff (mb_srelief30m.tif) with the following steps in Photoshop:
Open the bathymetry and shaded relief tiffs
Select the bathymetry tiff, and select image/mode/indexed color
Select image/mode/color table/load SeaNGDC13.act (found in the color tables folder of the GIS)
Select image/mode/RGB color
Select image/apply image/source, choose shaded relief tiff
Select image/adjustments/hue saturation/load Stell24bit12.ahu (found in the color tables folder of the GIS)
Select image/adjustments/hue saturation/load Stell24bit13_2.ahu (found in the color tables folder of the GIS)
Select image/mode/indexed color; palette (select local (selective)), colors (256), forced (none), transparency (off ), options (none).
Save as .tif; image compression (select none)
