This grid represents approximately 7 square kilometers of bathymetric data that were collected in Red Brook Harbor, Massachusetts, by the U.S. Geological Survey in 2009 as part of USGS survey 09018. Data were collected with a Systems Engineering and Assessment Ltd. (SEA) SWATHplus interferometric sonar system. These data are used to define the sea-floor morphology as part of the Massachusetts Sea-floor Mapping Project. The cell size for this grid is 1-meter by 1-meter.

These data are available as an Environmental Systems Research Institute (ESRI) 32-bit floating point GRID. 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. 9.0) software. To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an ESRI 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.
