Rapid wastage of the Hazen Plateau ice caps, northeastern Ellesmere Island, Nunavut, Canada
Two pairs of small stagnant ice bodies on the Hazen Plateau of northeastern Ellesmere Island, the St. Patrick Bay ice caps and the Murray and Simmons ice caps, are rapidly shrinking, and the remnants of the St. Patrick Bay ice caps are likely to disappear entirely within the next 5 years. Vertical aerial photographs of these Little Ice Age relics taken during August of 1959 show that the larger...
متن کاملThe climatic signal in varved sediments from Lake C2, northern Ellesmere Island, Canada
Annually-laminated clastic sediments preserve a high resolution proxy record of paleoclimate, provided that allochthonous sedimentation represents a response to meteorological forcing of watershed sediment transfer. Here, we demonstrate this linkage, and illustrate a calibration process using the most recent 40 years of a varve record from Lake C2 (82~ t N; 78000 ' W), three years of field meas...
متن کاملClimatic influences on streamflow and sediment flux into Lake C2, northern Ellesmere Island, Canada
Streamflow, suspended sediment transport and meteorological variables at two elevations were measured through the 1990-1992 field seasons at Lake C2, northern Ellesmere Island, as part of the Taconite Inlet Lakes Project. The objectives were to determine the extent to which suspended sediment flux responded to climatic variability, and to ascertain which meteorological variable was most strongl...
متن کاملA 300 year record of environmental change from Lake Tuborg, Ellesmere Island, Nunavut, Canada
Lamination thickness measurements in sediments from Lake Tuborg, northern Ellesmere Island, Canada document an increase in high-energy hydrologic discharge events from 1865 to 1962. The timing of these events corresponds with evidence for an increase in the amount of melt on the adjacent Agassiz Ice Cap, as recorded in ice cores. There appears to have been a non-linear change in depositional en...
متن کاملBison phylogeography constrains dispersal and viability of the Ice Free Corridor in western Canada.
The Ice Free Corridor has been invoked as a route for Pleistocene human and animal dispersals between eastern Beringia and more southerly areas of North America. Despite the significance of the corridor, there are limited data for when and how this corridor was used. Hypothetical uses of the corridor include: the first expansion of humans from Beringia into the Americas, northward postglacial e...
