Other ID: W2-90
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Michael Bothner
Data Type(s): Imagery: Video, Location-Elevation: Navigation, Sampling: Geology, Time Series: Mooring (physical oceanography), Visual Identification: Submersible Observations
Scientific Purpose/Goals: The objective of the program is to make long-term measurements of currents and sediment transport in the vicinity of the proposed ocean outfall in Massachusetts Bay. The purpose of this cruise was to recover and redeploy the instrumented moorings. Samples of bottom sediments are collected on each cruise required to service the instruments. This was the second in a series of six cruises during the 2 year period of the present Joint Funding Agreement between the Massachusetts Water Resources Authority and the USGS.
Start Port/Location: Boston Coast Guard Base, Boston, MA
End Port/Location: Boston Coast Guard Base, Boston, MA
Start Date: 1990-03-27
End Date: 1990-03-29
Equipment Used: Video camera - deep sea, Mooring tripod, Grab sampler - Van Veen , Corer - piston, Sextant, Northstar 6000 LORAN-C, Bottom platform, Submersible Observation
Information to be Derived: Time series data; Samples and chemical analysis; Suspended sediment concentrations;
Summary of Activity and Data Gathered: This cruise was extended to 3 days in order to recover the tripod which would not release its float on command. Using careful acoustic ranging and highly accurate triangulation, the position of the instrument was pinpointed. On the second day of the cruise (Mar. 28), divers from WHOI were placed within 50 ft. of the instrument and attached a retrieval line. All our equipment was recovered without damage. The divers reported that the recovery rope canister was detached from the tripod. A piece of fishing net remained on the tripod suggesting how the rope canister might have been damaged. Moorings deployed: 2 (#340 and 341, recovered FA 90016 WHITE HEATH July 10-11, 1990). Moorings recovered: 2 (#338 and 339, deployed FA 89035 WHITE HEATH Dec. 5-6, 1989).
