Field Activity Details for field activity 2000-004-FA

Other ID: MH34-00; IB H-4-00-MY

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: Massachusetts Bay, Scituate, Massachusetts, United States, North America, North Atlantic;

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s): William Martin - WHOI

Information Specialist(s): Michael Casso, Frances Lightsom

Data Type(s): Environmental Data: Dissolved Oxygen, Geochemical: Experiments, Imagery: Photo, Imagery: Video, Sampling: Geology, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Three day trips were completed. Day 1: Exchanged moorings off Boston and Scituate. Day 2: Collected sediment cores with the new hydraulically damped corer at Stations 2, 3 and 3b (near the benthic chamber deployment site). Deployed and recovered oxygen profiler - 2 times at Station 3 and once at Station 2. Recovered one benthic chamber by SCUBA divers. The second chamber was not found. Day 3: An attempt was made to recover the lost slow corer from location east of Stellwagen Bank at 200 m water depth. A three grapling hook assembly (on an 8-foot spreader) was used with a camera attached to the middle hook. Dann Blackwood arranged 6 submersible flashlights on the central hook which did a good job illuminating to the side and bottom. The whole assemblage was lowered on half-inch tenex rope (breaking strength about 11,000 lbs). Approximately 2 hours were spent on and around the last known position of the core. It was not seen in the camera, nor was it hooked during the dragging operation.

Information to be Derived:

Summary of Activity and Data Gathered: Lary Ball was the lead diver. Richard Rendigs and Dann Blackwood also made a dive to recover the second benthic chamber. The marker float for this chamber was missing when we arrived on station. A second marker float drifted between the time of initial confirmation of the chamber location (based on the diver-held acoustic range finder) and the actual dive. As a result, the chamber was not recovered. Moorings recovered: 4 (#624, 625, 626 and 627, all deployed FA 00003 MARCUS HANNA May 9-10, 2000). Moorings deployed: 5 (#630, 631, 632 and 634, all deployed FA 01022 MARCUS HANNA Feb. 13-14, 2001; #633 recovered FA 01051 CHRISTOPHER ANDREW Mar. 20, 2001).
