ObjectivesThe objective of the cruise, which is one of a series, was to study the overflow of Norwegian sea water across the Iceland Faroes Ridge and through the Faroe Bank Channel, the formation of North Atlantic Deep Water in the Iceland Basin and to observe its passage through the Charlie-Gibbs Fracture Zone in the western Atlantic. The following tasks were undertaken:
1. Recovery of an array of moorings in the Faroe Bank Channel and an inverted echosounder/pressure recorder at its exit.
2. Further trials of an acoustic travel time monitor.
3. Hydrographic observations with a CTD together with water samples drawn for the analysis of salinity, dissolved oxygen, silicate and Freon 11 and 12. These observations to be made where moorings were laid/recovered and on a section across the Iceland Basin near 57N.
4. Deployment of an array of moorings in the Charlie-Gibbs Fracture Zone for a period of 1 year.
