Summary for Field Activity Number 1981-002-FA

Alternate Leg ID: 91

Area of Operations: Georges Bank, Lydonia Canyon, United States, North America, North Atlantic

Dates: January 16, 1981 to January 22, 1981

Objectives: Collect CTD and suspended matter samples and deploy two moorings in Lydonia Canyon. Collect surface grab samples near Lease Block 312 (for analysis of texture, trace metals, petroleum hydrocarbons, and benthos). Collect grab samples at four long-term stations for benthic seasonal and transport changes. Collect grab samples to map surficial sediment in Lydonia Canyon.
