Última Holocene ice-rafting and sediment transport from the glaciated margin of East Greenland (67-70 degrees N) to the N Iceland shelves: detecting and modelling changing sediment sources ArchiMer Andrews, John T.; Bigg, Grant R.; Wilton, David J.. We examine variations in the ice-rafted sources for sediments in the Iceland/East Greenland offshore marine archives by utilizing a sediment unmixing model and link the results to a coupled iceberg-ocean model. Surface samples from around Iceland and along the E/NE Greenland shelf are used to define potential sediment sources, and these are examined within the context of the down-core variations in mineralogy in the <2 mm sediment fraction from a transect of cores across Denmark Strait. A sediment unmixing model is used to estimate the fraction of sediment <2 mm off NW and N Iceland exported across Denmark Strait; this averaged between 10 and 20%. Both the sediment unmixing model and the coupled iceberg-ocean model are consistent in finding that the... Tipo: Text Palavras-chave: Holocene; Ice-rafting; Ice bergs; East Greenland; Iceland.
