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. 2.0, April 2018): 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 [...]

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.
