One day trip to deploy a benthic chamber and a second day trip to recover the chamber 4-5 days later. Dates are uncertain. The benthic chambers will measure the flux of metals and nutrients from the sediments of Hull Bay. The chamber weighs about 150 lbs in air and is in the shape of a tripod, 3 feet on a side. A detachable black and white camera will be used to check the placement on the bottom.
Location
Hull Bay, Boston Harbor, Massachusetts, United States, North America, North Atlantic;
Summary
The deployment and recovery of chambers was accomplished. Divers collected excellent core samples.
Comments
On June 4, 2001, Joanne Goudreau's hand was badly cut when two fingers were caught between wire and a pulley as the benthic chamber was deployed. She was brought to the local hospital's emergency room, treated and released, with expectation of a slow but full recovery. A full accident report was filed by Dave Nichols. Original Center People field contained: Dave Nichols - boat captain. Science crew from USGS: Mike Bothner, Dann Blackwood.
