USGS Coastal and Marine Geology Program

Field Activity Details for field activity 1976-031-FA

Other ID: OC 13-3

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Bradford Butman, David W. Folger

Affiliate Investigator(s): Robert C. Beardsley - WHOI

Information Specialist(s):

Data Type(s): Environmental Data: CTD, Environmental Data: Temperature, Environmental Data: Turbidity, Sampling: Chemistry, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: 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.
