Summary for Field Activity Number 1978-024-FA

Alternate Leg ID: 78-G7; 78-G-7

Area of Operations: Georges Bank, Mud Patch, Middle Atlantic Outer Continental Shelf, Massachusetts, New Jersey, United States, North America, North Atlantic

Dates: August 19, 1978 to September 01, 1978

Objectives: Collect hydrographic and suspended matter data on Georges Bank and continental shelf areas off the New England and Middle Atlantic States. This is an ongoing study to determine the seasonal distribution and composition of suspended matter along the eastern seaboard. Additional cruise objectives were the deployment and recovery of three moorings with attached current meters and sediment traps. Sediment samples were collected at three locations with a grab sampler and with a hydrostatically damped gravity corer.

Type of Activity: Sampling
Mooring work

Information to be derived: Grain size analysis
Time series data
Samples and chemical analysis
Suspended sediment concentrations

Summary: Stations: 13; XBT (underway): 127; CTD/Transmissometer/suspended matter stations: 116; Sediment trap arrays: 3; 24-hour monitoring stations: 3; Suspended Matter Millepore samples: 286; Suspended Matter Nucleopore samples: 187; Suspended Matter Mineralogy samples: 79; Chlorophyll samples: 276; Nutrient samples: 274; Grab samples: 4; Cores: 3. Moorings deployed and recovered: 3 (#154, VACM w/transmissometer; 2 current meters w/ sediment traps).
