Holocene thinning of the Greenland ice sheet
On entering an era of global warming, the stability of the Greenland ice sheet (GIS) is an important concern, especially in the light of new evidence of rapidly changing flow and melt conditions atExpand
Perfluorinated acids in Arctic snow: new evidence for atmospheric formation.
Perfluorinated acids (PFAs) are ubiquitously found in water and biota, including remote regions such as the High Arctic. Under environmental conditions, PFAs exist mainly as anions and are notExpand
Elevation changes of ice caps in the Canadian Arctic Archipelago
[1] Precise repeat airborne laser surveys were conducted over the major ice caps in the Canadian Arctic Archipelago in the spring of 1995 and 2000 in order to measure elevation changes in the region.Expand
Holocene climatic records from Agassiz Ice Cap, Ellesmere Island, NWT, Canada
Four ice cores from the top of the Agassiz Ice Cap and down a flow line have been variously analysed for 8 (18O), ECM (solid conductivity) and ice-melt layer stratigraphy. Stratigraphic correlationExpand
A record of Holocene summer climate from a Canadian high-Arctic ice core
MELT layers in ice cores are formed by melting on the snow-pack surface, which produces water that percolates down and refreezes in the colder snow layers below. Melt layers are distinguished byExpand
Near-Surface Temperature Lapse Rates over Arctic Glaciers and Their Implications for Temperature Downscaling
Distributed glacier surface melt models are often forced using air temperature fields that are either downscaled from climate models or reanalysis, or extrapolated from station measurements.Expand
Devon Island Ice Cap: Core Stratigraphy and Paleoclimate
Valuable paleoclimatic information can be gained by studying the distribution of melt layers in deep ice cores. A profile representing the percentage of ice in melt layers in a core drilled from theExpand
Mass balance of glaciers in the Queen Elizabeth Islands, Nunavut, Canada
Abstract Mass-balance measurements began in the Canadian High Arctic in 1959. This paper considers the >40 years of measurements made since then, principally on two stagnant ice caps (on Meighen andExpand
Ice core studies of anthropogenic sulfate and nitrate trends in the Arctic
Ice core studies have shown that sulfate and nitrate concentrations in Arctic snow have increased significantly since the end of the 19th century due to the influx of anthropogenic pollutantsExpand
