50,000 years of paleoenvironmental change recorded in meteoric waters and coeval paleoecological and cryostratigraphic indicators from the Klondike goldfields, Yukon, CanadaDownload
A 50,000 year record of meteoric water isotopes (δ2H/δ18O) and paleoenvironmental conditions is presented from syngenetic ice-rich permafrost and macrofossils from eight sites in the Klondike area of central Yukon. Four sedimentary units are recognized based on cryostratigraphy, paleoecological...
Polar warming will lead to increased labile organic carbon in Arctic soils, both from the release of organic carbon stored in permafrost and increased plant production. The impact of increasing organic carbon on Arctic soil microbial community composition and activity is of great interest...
Abstract: An improved corer and associated equipment for obtaining continuous samples of frozen peat are described. We developed the system through laboratory and field trials-on Bathurst Island, Nunavut, Canada in 2000 and Nordvesto, Carey Islands, Greenland, in 2001-as part of efforts to...
Masters thesis. Examines significant aspects of hydrogeology, hydrogeochemistry, and evidence of groundwater flow as basis for understanding groundwater distribution and development in permafrost regions. Engineering considerations on development of groundwater resources and prevention of icings...
The Alaska Highway through Southwestern Yukon is located in the discontinuous permafrost zone with many areas of the highway corridor associated with degrading permafrost. Given the strategic value of the corridor, it is critical to have a clear understanding of permafrost characteristics and...
Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, CanadaDownload
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...
Examining Historical Climate with Respect to Future Permafrost and Engineering Design: An Analysis of Common Assumptions and CalculationsDownload
This paper examines changes in climate with respect to permafrost and engineering design in Arctic regions. Current understanding of climate changes, predictive modeling, and climate data were studied. Inconsistencies and differences were noted, discussed, and evaluated using comparisons of the...
In Arctic Canada, government agencies, Indigenous organizations and private organizations publish in a variety of languages, dialects and scripts. Often materials are published in several different linguistic editions. Two of the pictured volumes are published by the Government of Nunavut and...
Abstract: A pile load test program carried out in Iqaluit, Northwest Territories, to provide design information for the Short Range Radar sites is described. The program consisted of testing 10 steel pipe piles with various surface modifications backfilled with clean sand and 4 Dywidag bars...
Abstract: The results obtained from 14 pile load tests carried out in saline permafrost at Iqaluit, Northwest Territories, are analyzed with respect to (i) the development of load along the length of the piles as determined from strain gauges mounted along the embedded portion of the piles; (ii)...
