Keewatin Ice Sheet—Re-evaluation of the traditional concept of the Laurentide Ice Sheet
Patterns of dispersal of distinctive Proterozoic and Paleozoic erratics across terrain formed on Archean and Aphebian crystalline rocks indicate that (1) ice never f lowed from Hudson Bay into Keewatin in the region from the Manitoba border (lat 6 0 ° N ) northward at least to lat 65°N; (2) westward-southwestward f low out of the bay, probably from a Labradorean dispersal center, interfaced wit...
متن کاملYounger Dryas Interval and Outflow from the Laurentide Ice Sheet
A boxmodel of the Great Lakes is used to estimate meltwater flow into the North Atlantic between 8000 and 14,000 calendar years B.P. Controls on the model include the oxygen isotopic composition of meltwaters and lake waters as measured in the shells of ostracodes. Outflow rates are highest when oxygen isotopic values of the lake waters are most negative, denoting a maximum glacial meltwater co...
متن کاملGlobal Warming and the Greenland Ice Sheet
The Greenland coastal temperatures have followed the early 20th century global warming trend. Since 1940, however, the Greenland coastal stations data have undergone predominantly a cooling trend. At the summit of the Greenland ice sheet the summer average temperature has decreased at the rate of 2.2 ◦C per decade since the beginning of the measurements in 1987. This suggests that the Greenland...
متن کاملSea ice thickness and recent Arctic warming
The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations using the EC-Earth atmospheric model (Integrated Forecast System) are performed and analyzed to quantify the atmospheric impacts of Arctic sea...
متن کاملIce-Rafted Detritus Events in the Arctic During the Last Glacial Interval, and the Timing of the Innuitian and Laurentide Ice Sheet Calving Events
Ice-rafted detritus (IRD) layers in the Arctic Ocean not only indicate the source of this detrital sediment, but give insights into the ice drift and ice sheet history. Detrital sand-sized Fe oxide mineral grains that are matched to precise sources using the microprobe chemical fingerprint of each grain, along with elevated coarse IRD abundance and radiocarbon ages, are used to define IRD peaks...
