Determination of sediment provenance by unmixing the mineralogy of source-area sediments: The “SedUnMix” program
John T. Andrews,Dennis D. Eberl +1 more
TL;DR: In this paper, four end-member source sediments were mixed in various proportions to form eleven artificial mixtures, two of which were felsic and two were mafic.
North-eastern Laurentide, western Greenland and southern Innuitian ice stream dynamics during the last glacial cycle
TL;DR: In this paper, the influence of ice streaming activities from the north-eastern Laurentide, southern Innuitian and western Greenland ice margins on sedimentary regimes during glacial times is investigated.
Late Quaternary stratigraphy, chronology, and depositional processes on the slope of S.E. Baffin Island, detrital carbonate and Heinrich events: Implications for onshore glacial history
TL;DR: In this paper, 40 radiocarbon dates have been obtained on foraminifera from nine, 2.5 to 11 m piston cores from the slope of SE Baffin Island.
The use of hypsometry to indicate long-term stability and response of valley glaciers to changes in mass transfer
D.J Furbish,John T. Andrews +1 more
TL;DR: In this paper, a simple equation is derived relating the net mass-balance and hypsometric curves of a steady-state valley glacier to examine how valley shape is linked to disparate extents and responses of glaciers subjected to similar climatic conditions.
Baffin Bay/Nares Strait surface (seafloor) sediment mineralogy: further investigations and methods to elucidate spatial variations in provenance
TL;DR: In this article, the authors ascertain whether there are significant regional variations in sediment mineral composition that might be used to elucidate ice sheet histories, and the weight percentages of these variations are used to infer ice sheet history.
