BODC Cruise Metadata Report for RRS Discovery (74E3) cruise D309-310

Introduction

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

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D309-310
Short name D309-310
Objectives and Narrative A Deep Western Boundary Current array of seven moorings was recovered and a replacement array of five moorings was deployed. For IFREMER, one mooring and one glider were recovered; one IfM-GEOMAR and three NIOZ moorings were recovered, serviced and redeployed. Hydrographic work comprised 25 CTD/LADCP stations, and three tows of the Moving Vessel Profiler (MVP); water samples were captured on each station for the measurement of salinity.
Continuous underway measurements comprised: navigation; currents, using ship-mounted ADCPs (75 and 150 kHz); meteorology; sea surface temperature and salinity; and bathymetry. D309-310 (CFER-2) is a part of the project "Cape Farewell and Eirik Ridge: Interannual to Millennial Thermohaline Circulation Variability", funded by the UK Natural Environment Research Council as part of its "Rapid Climate Change" Directed Research Programme.
