The Late Quaternary Sedimentary Record of Reykjanes Ridge, North AtlanticPrins, M. A.; Troelstra, S. R.; Kruk, R. W.; van der Borg, K.; de Jong, A. F. M.; Weltje, G. J. (Department of Geosciences, The University of Arizona, 2001-01-01)Variability in surface and deep ocean circulation in the North Atlantic is inferred from grain-size characteristics and the composition of terrigenous sediments from a deep-sea core taken on Reykjanes Ridge, south of Iceland. End-member modeling of grain size data shows that deep-ocean circulation in this area decreased significantly during periods of maximum iceberg discharge. The episodes of reduced circulation correlate with the cold and abrupt warming phases of the Dansgaard-Oeschger cycles as recognized in the Greenland ice cores.
