This grid is a hillshade illustrating the shaded relief of approximately 410 square kilometers of bathymetric data that were collected in 2004, 2009, 2010, and 2011. It is derived from a merged grid of interferometric (Systems Engineering and Assessment Ltd. SWATHPlus-M) and multibeam (RESON SeaBat 8125) bathymetric sonar data that were collected by the U.S. Geological Survey and the National Oceanic and Atmospheric Administration, respectively, during four surveys (USGS surveys 2009-002-FA, 2010-004-FA and 2011-004-FA; and NOAA survey H11319 in 2004) offshore of Massachusetts, in Buzzards Bay. These data are used to define the seafloor morphology as part of the Massachusetts Seafloor Mapping Project

These data are available as a ArcInfo 16-bit integer binary grid in Esri format. The grid consists of two folders, one with the "grid name", and one "info" folder. The two folders for each grid are compressed into one file using WinZip (ver. 14.0) software. To utilize these data, the user must have software capable of uncompressing the zip file and importing and viewing an Esri ArcRaster grid. The two folders for each grid must be uncompressed to the same folder. Extracting grids from different publications into the same folder is not recommended and will likely render some of your grids unusable. The zip file also contains associated metadata.
