Field Activity 1977-032-FA

Identifier 1977-032-FA
Alternate names Legs I and II
Purpose 1. Recover 5 instrumented bottom tripod packages and deploy 2 tripods as part of a continuing study of currents and sediment transport on the east coast continental shelf. 2. Recover 2 current meter moorings and deploy 3 current meter moorings as part of a continuing study of currents and sediment transport. Deploy 2 current moorings for EG&G. 3. Make underway XBT observations of water temperature and structure and obtain profiles of temperature and conductivity (CTD) along selected transects running across shelf and along shelf. Measurements were designed to determine position of shelf-slope water front, to aid in interpretation of tripod and current meter data, to map distribution of cold pool water found on the shelf in summer off the New Jersey coast, and to study mixing through Great South Channel. 4. Recover, replace, and relight as necessary surface marker floats at tripod and current meter locations. Floats serve to mark instrument locations and deter fishing activity.
