| Summary: | Cruise Charles Darwin 159 was primarily devoted to coring with ancillary CTD work in the North Atlantic between Scotland and Newfoundland. The sampling program was most successful, due to unusually good weather in July (1-30, 2004), recovering 30 box cores, 19 piston cores, 6 kasten cores, 9 other short gravity cores and 20 CTD casts as well as 28 surface water samples for trace metals, 28 for plankton and isotopes, and 20 filtered for foraminifera. It was undertaken in support of the NERC RAPID Climate Change programme. Objectives are to generate palaeoceanographic records of hydrographic changes (temperature, salinity, nutrients, flow speed) associated with sharp climate transitions of the last 16 ka seen in the Greenland ice cores. Samples and CTD casts were also taken at sites of former current meter deployments to calibrate proxies for flow speed and other hydrographic variables. Sampled areas were north of Rockall, S. Iceland slope and rise, Gardar Drift, S.E. Greenland margin, Eirik Drift, and Hamilton Spur and Orphan Spur off Labrador. |
