The sediments were collected with a modified Van Veen grab (mini-SEABOSS) during USGS survey 04019, conducted September 14-17, 2004. 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.
