Cosmogenic exposure dating in arctic glacial landscapes: implications for the glacial history of northeastern Baffin Island, Arctic Canada
Cosmogenic exposure dating and detailed glacial-terrain mapping from the Clyde Foreland, Baffin Island, Arctic Canada, reveal new information about the extent and dynamics of the northeastern sector of the Laurentide Ice Sheet (LIS) during the last glacial maximum (LGM). The Clyde Foreland is composed of two distinct landscape zones: (1) glacially scoured terrain proximal to the major sources o...
متن کاملPreference for nearshore and estuarine habitats in anadromous Arctic char (Salvelinus alpinus) from the Canadian high Arctic (Victoria Island, Nunavut) revealed by acoustic telemetry
Weused an array of fixed acoustic receivers (N = 42) to track the summermarinemovements of 121 anadromous Arctic char (Salvelinus alpinus) equipped with acoustic transmitters at three locations in the Cambridge Bay region, where commercial and subsistence fisheries target the species. The timing of transitions between salt and freshwaterwas influenced by the putative river of origin of tagged i...
متن کاملSupport for the Innuitian Ice Sheet in the Canadian High Arctic during the Last Glacial Maximum
The extent of glacier ice in the Canadian High Arctic during the Last Glacial Maximum (LGM) has been debated for decades. One school proposed a regional Innuitian Ice Sheet whereas another proposed a smaller, non-contiguous Franklin Ice Complex. Research throughout western Nares Strait supports coalescent Innuitian and Greenland ice during the LGM, based on widespread glacial and marine deposit...
متن کاملTaxonomic Composition, Paleoecology and Biostratigraphy of Late Cretaceous Diatoms from Devon Island, Nunavut, Canadian High Arctic
Diatoms are the most diverse group of algae, playing a major role in global carbon and silicon cycles (Kidder and Erwin, 2001; Armbrust, 2009) and inhabiting virtually any environment that provides moisture and sunlight (Mann, 1999). Thus, they offer important information to help reconstruct paleoen-vironments and clarify stratigraphic relationships. Their strati-graphic range extends down at l...
متن کاملMiocene and Pliocene paleoclimate of the Dry Valleys region, Southern Victoria land: a geomorphological approach
The Dry Valleys region is a hyper-arid, cold polar desert. Modem climate varies systematically with increasing elevation and distance from the coast. We distinguish three microclimate zones on the basis of varying precipitation, wind direction, relative humidity, temperature, and soil-moisture content. Zone 1 represents coastal, Zone 2 intermediate, and Zone 3 far-western areas of the Dry Valle...
