The objective of the cruise was to collect twelve vibracores from specified sites within Boston Harbor. The location of these sites was determined from selected high-resolution seismic survey lines conducted during the summer of 1987 by the U.S. Geological Survey. The cores will be x-rayed, split, described, photographed and subsampled for geochemical, geotechnical and sedimentologic analyses. Correlation of lithologic results will be utilized to further define the Holocene and Pleistocene stratigraphic history of Boston Harbor.
Location
Boston Harbor, Massachusetts Bay, Massachusetts, United States, North America, North Atlantic;
Summary
A 10- to 15-minute high-resolution seismic survey was conducted at each site prior to coring operations. A buoy was then deployed along the seismic line as a marker for each coring site. The ship would then anchor alongside the buoy and commence coring operations. Survey stations: 11; Coring stations: 12; Seismic data: 9.63 km.

Assumption that it's a 3.5 system and not the GeoPulse boomer system - so using the ORE
