Andrews, B.D., Baldwin, W.E., Sampson, D.W., and Schwab, W.C., 2018, Continuous bathymetry and elevation models of the Massachusetts coastal zone and continental shelf (ver. 3.0, December 2019): U.S. Geological Survey data release,


Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Provincetown and Scituate and east to Stellwagen Bank; Cape Cod Bay from Provincetown to Scituate and south to Hyannis; Buzzards Bay from the Cape Cod Canal southwest to the State border including the Elizabeth Islands and extending north to Fall River and Mount Hope Bay; and Nantucket and Vineyard Sounds, from Hyannis south to the border of [...]

Provide a continuous surface starting in the offshore waters and working inshore to the shoreward extent of the Massachusetts Coastal Zone that will be used as a regional planning framework. This model, used in conjunction with the related source dataset shapefile will also 1) Provide an inventory of the most recent elevation and bathymetry datasets within the Massachusetts Coastal Zone and offshore water, and 2) Identify areas of the offshore waters that are only covered by historical lead line soundings and should be updated using new survey methods.

Changes in version 2.0: The MassBay_10m.tif file that was originally uploaded to ScienceBase on February 5, 2018, was an incorrect version. The “MassBayTer” terrain described in Processing Step 8 had been updated prior to publication, but it was not re-exported to create the final version of the MassBay_10m.tif file. This was fixed by rerunning Processing Step 8 to createMassBay_10m_V2.tif, a new GeoTIFF file. The only changes reflected in MassBay_10m_V2.tif are described below. 1) There was a small 10-meter (one cell) gap between National Oceanic and Atmospheric Administration surveys W00044 and W00039 in Stellwagen Bank that produced a gap in the final grid. This was corrected by editing the "MassBayTerBnd" feature class to remove the boundary and the gap. 2) A vertical offset between the U.S. Geological Survey Stellwagen Bank National Marine Sanctuary data and surrounding surveys of 2-3 meters was fixed by reprocessing the data through VDatum (ver. 3.6) with the correct transformation parameters and replacing the source multipoint file (USGS_SBNMS_10m_MP_navd88) in the terrain model.
