RRS Discovery Cruise 309-310, 18 Aug-05 Sep 2006. Cape Farewell and Eirik Ridge (CFER-2)

This report describes scientific activities during RRS Discovery cruise 309-310 in the vicinity of Cape Farewell, southern Greenland, during late summer 2006. 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.
