Summary for Field Activity Number 1976-031-FA

Alternate Leg ID: OC 13-3

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

Dates: August 12, 1976 to August 23, 1976

Objectives: 1. Measure distribution of temperature and salinity in the vicinity of Georges Bank and along the shelf west of Georges Bank to acquire a synoptic picture of the regional density field to aid in interpretation of current meter records and to study mixing and transport in the Georges Bank region of the New England Continental Shelf. 2. Measure the distribution of suspended matter using optical techniques in the vicinity of Georges Bank and along the shelf west of Georges Bank. Collect and filter water samples to calibrate the optical sensor and to determine the composition of suspended material. These measurements are designed to study seston flux in the region. 3. Recover USGS moorings 107, 108, 109, 110, and 111. 4. Deploy USGS mooring 115.
