Abstract
Taking advantage of the continuous high resolution magnetic techniques, we have studied the magnetic properties of six deep-sea cores located in the Nordic seas and in North Atlantic along an E-W transect between 58° to 67°N. The study has been focussed on climatic stage 3 during which these cores exhibit large amplitude short term variations in the bulk magnetic parameters, in relation with rapid climatic changes. In each core, the magnetic mineralogy is uniformly composed of well sorted low Ti-content magnetites associated with paramagnetic minerals. This uniformity indicates that short term variations in the bulk magnetic parameters only illustrate variations in the amount of magnetic minerals transported by deep currents and deposited at the different sites. The fast climatic changes are thus related to coeval fast changes in the strength of the deep-sea circulation. During interstadials the latter took place in the Norwegian sea and transported the magnetic particles into the North Atlantic ocean along a path similar to the present day path of the NADW. During stadials and Heinrich events, this deep circulation was strongly reduced. A tentative comparison of the amount of magnetites transported by the deep current and deposited at the studied sites suggests that the Faeroe-Shetland channel and the Denmark strait were the only two active path for the overflow water during climatic stage 3.
