Summary for Field Activity Number 1976-022-FA

Alternate Leg ID: 76-1

Area of Operations: Great South Channel, Georges Bank, United States, North America, North Atlantic

Dates: July 01, 1976 to July 07, 1976

Objectives: Evaluate changes in bottom configuration and biology in areas where railroad wheels and pipes were set in 1975, and search for a lost current meter array.

Type of Activity: Sampling
Mooring work
Photography
Tripod performance

Information to be derived: Suspended sediment concentrations

Summary: At mooring site 110, where a lost current meter array was sought, heavy fog prevented an extensive search for the equipment. Railroad wheel was located and extensively photographed at station 4503. Diving operations during the whole cruise were severely restricted by heavy fog during part or all of each day. Sea conditions were most often good but visibility was not generally within operating minimums. Dives: 8 (#683, 684, 685, 686, 687, 688, 689, and 690); Stations: 2 (4502 and 4503); Transmissometer casts: 10; Hydrocasts: 6; Nephelometer: 1; Suspended matter samples: 5; XBTs: 0; Videos; Photos. Lost current meter was not located at site 110; biology surveys were successful at site 4503.
