Summary for Field Activity Number 80001

Alternate Leg: ID (80-Legs I, II, III)

Area of Operations : Georges Bank, Mid-Atlantic Continental Shelf, United States, North America, North Atlantic

Dates: January 3, 1980 to January 23, 1980

Chief scientist: Brad Butman
   

Objectives: Objectives were to recover instrumentation on the continental shelf.We planned to recover the instruments on OCEANUS 77 (#79035, Dec 13-20, 1979) but the acoustic releases failed, due to a bad set of release batteries. Moorings to be recovered: Station Q (40 30N, 70 13W) recover tripod mooring 178, deploy current mooring 191; Station B (38 44N, 73 38W) recover current mooring 180, recover tripod mooring 177. All instruments were recovered by grappling since releases failed. We planned cross-shelf XBT sections. Sidescan sonar was used to locate the moorings.

Type of Activity: Mooring work

Information to be derived: Times series data
Suspended Sediment Concentrations

Summary: Mooring deployed:1 (#191 recovered #80009 OCEANUS 081 May 23-Jun 1, 1980); Tripod recovered:2 (#177,178 both deployed #79021 OCEANUS 067 Aug 6-13, 1979); Mooring lost:1 (#180 VACM 0512 lost, deployed #79021 OCEANUS 067 Aug 6-13, 1979) XBT:23; Surface salinity samples:23
