The Laurentide and Innuitian ice sheets during the Last Glacial Maximum
Arthur S. Dyke,John T. Andrews,Peter U. Clark,John England,Gifford H. Miller,J Shaw,Jean J. Veillette +6 more
TL;DR: The Late Wisconsinan advance of the Laurentide Ice Sheet started from a Middle Wisconsinan interstadial minimum 27−30 14 C ka BP when the ice margin approximately followed the boundary of the Canadian Shield.
Journal ArticleDOI
Central Arctic surface ocean environment during the past 80,000 years
TL;DR: Stable oxygen and carbon isotope and sedimentological-paleontological investigations supported by accelerator mass spectrometry (14)C datings were carried out on cores from north of 85 degrees N in the eastern central Arctic Ocean as discussed by the authors.
Journal ArticleDOI
Last Glacial Maximum and deglaciation of devon island, arctic canada: support for an innuitian ice sheet
TL;DR: The extent and origin of Quarternary glaciers in the Queen Elizabeth Islands of Arctic Canada, especially during the Last Glacial Maximum (LGM), has been debated for well over a century as mentioned in this paper.
Journal ArticleDOI
Reconciling records of ice streaming and ice margin retreat to produce a palaeogeographic reconstruction of the deglaciation of the Laurentide Ice Sheet.
TL;DR: The authors reconstructs the deglaciation of the Laurentide Ice Sheet from the Last Glacial Maximum (LGM), with a particular focus on the spatial and temporal variations in ice streaming and the associated changes in flow patterns and ice divides.
Journal ArticleDOI
Origin of ice-rafted debris: Pleistocene paleoceanography in the western Arctic Ocean
TL;DR: In this paper, the composition of ice-rafted debris (IRD) >250 gm was analyzed quantitatively by grain counting in five sediment cores from the western central Arctic Ocean and compared with the composition from NW Canada in order to determine the dropstone origin and to reconstruct the Pleistocene ice drillways and surface currents.

A new greenland deep ice core.
Willi Dansgaard,Henrik Clausen,Niels S. Gundestrup,Claus U. Hammer,Sigfus J Johnsen,P. M. Kristinsdottir,Niels Reeh +6 more
TL;DR: The details in the Wisconsin part of the ice core records seem to be climatically, significant, and the general trends reveal all of the relevant Emiliani stages recorded in deep-sea cores.
Journal ArticleDOI
Isostatic response to loading of the crust in Canada
TL;DR: In this article, a smoothed free air anomaly map of Canada indicates that the central part of the region occupied by the Laurentide Ice Sheet is over-compensated due to incomplete recovery of the lithosphere from the displacement caused by the Pleistocene ice loads.
Journal ArticleDOI
Acidity of polar ice cores in relation to absolute dating, past volcanism, and radio-echoes
TL;DR: In this paper, a simple method is described for detecting annual stratification of ice cores, and layers of high acidity due to violent volcanic eruptions in the past, based on a relationship between the H3O+ concentration (pH) of melted samples and the electrical current between two brass electrodes moved along the cleaned ice-core surface.
Journal ArticleDOI
Was there a late-Würm Arctic Ice Sheet?
TL;DR: In this paper, a simplification and synthesis of late-Wurm Northern Hemisphere glaciation is proposed by postulating an Arctic Ice Sheet that behaved as a single dynamic system.
