Field Activity 1978-024-FA

Identifier 1978-024-FA
Alternate names 78-G7; 78-G-7
Purpose 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.
