Summary
Abstract: This data set includes the locations, identifiers, grain-size data and(or) textural descriptions of surficial sediments collected at stations based on topographic and backscatter data of the seafloor in Boston Harbor and the harbor appraoches, Massachusetts. The sediments were collected with a modified Van Veen grab (mini-SEABOSS) during USGS survey 04019, conducted September 14-17, 2004. Note: These data were converted from their native projection to the Massachusetts State Plane coordinate system, Mainland Zone (Fipszone 2001), meters by the Massachusetts Department of Coastal Zone Management on Oct. 19, 2006.

Purpose: This data set was produced to ground-truth (verify) topography and backscatter intensity of the seafloor in Boston Harbor and the harbor appraoches, Massachusetts. The acoustic data associated with this project were collected with multibeam, vertical-beam and sidescan sonar systems in 2000 and 2001, by NOAA NOS for hydrographic mapping purposes.
