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...

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...

This thesis contributes to the development of chronological and geological frameworks for the archaeological record of the mineable oil sands regions in northeastern Alberta, Canada. This area contains a rich pre-European contact archaeological record that has largely been documented through...

In order to understand permafrost and paleoenvironmental conditions in the Mackenzie Delta Region, permafrost cores were collected in the winter of 2017, near the newly developed Inuvik-Tuktoyaktuk Highway (ITH), NWT, by the NWT Geological Survey, NWT Department of Infrastructure, the University...

Lake Agassiz was dammed on the retreating southern and western margins of the Laurentide Ice Sheet during the end of the last Ice Age. Periodic discharges of freshwater from the lake basin have been implicated in altering oceanic circulation and impacting global climate. Meltwater from a rapid...

In this dissertation, tephrostratigraphy is used as the central method to address issues of chronology in the late Quaternary sedimentary record of eastern Beringia (non-glaciated Yukon and Alaska) at a variety of spatial and temporal scales. The Palisades, central Alaska, preserves...

Environmental archives provide a feasible means for studying the biogeochemical cycling of heavy metals including mercury (Hg). Although many temperate peat bogs have been successfully used to reconstruct natural and anthropogenic atmospheric Hg deposition fluxes, northern circumpolar permafrost...

Cryptotephra research is one of the fastest growing subfields of tephrochronology. Here the extraction, processing, and analytical techniques required for cryptotephra studies are reviewed and assessed in detail. A workflow is suggested depending on the site’s characteristics to improve the...

The Edmonton-area landscape has been shaped by multiple geomorphic events throughout the Quaternary period. These events account for the distribution of resources and landforms across Central Alberta, making their reconstruction essential to understanding the geomorphic history of the Canadian...

The lower Athabasca River valley in northeastern Alberta, famous for oil sands mining, was also the site of one of North America largest Ice Age floods. During deglaciation, a large proglacial lake, Lake Agassiz, drained catastrophically through the Athabasca River valley. This catastrophic flood...
