Ship name (ship code)RRS Charles Darwin (74AB)
Cruise identifierCD51
Cruise period1990-07-24 — 1990-08-21
StatusCompleted
Port of departureAberdeen, United Kingdom
Port of returnTroon, United Kingdom
PurposeResearch
ObjectivesThe cruise gathered information for an IOSDL Laboratory Research Project on "Processes Determining the Structure of the Upper Ocean" and formed part of the UK contribution to the WOCE. The operational area covered the inflow of North Atlantic Water to the Greenland-Iceland-Norwegian Sea between the Shetlands and Iceland. The survey method involved towing a CTD inside the SeaSoar profiling vehicle and combining the data with the shipboard ADCP. Two wide area surveys, one east of, and one west of, the Faeroes were completed. The evolving eddy structure of the Iceland-Faeroes Front was then examined by three repeated small scale surveys.
