BODC Cruise Metadata Report for RRS Charles Darwin (74AB) cruise CD51

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Charles Darwin (74AB) cruise CD51
Short name CD51
Objectives and Narrative The 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.
