Discovery of relict subglacial lakes and their geometry and mechanism of drainage
Autor: Stephen J. Livingstone, Daniel J. Utting, Alastair Ruffell, Chris D. Clark, Steven Pawley, Nigel Atkinson, Andrew C. Fowler
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-9 (2016)
Our understanding of subglacial lake drainage events is limited by a lack of direct observations. Here, the authors use ground penetrating radar to identify a relict subglacial lake and infer drainage mechanisms based on geomorphological features.

A New Year’s Day icebreaker: icequakes on lakes in Alberta, Canada
Autor: D J Utting, J. L. Kavanaugh, Gail M. Atkinson, Mirko van der Baan, Laurence D. Andriashek, Ryan Schultz, Hadi Ghofrani
Publikováno v: Canadian Journal of Earth Sciences. 56:183-200
Any process that causes a sudden brittle failure of material has the potential to cause earthquake-like seismic events. Cryoseisms represent an underreported class of seismic event due to their (often) small magnitudes. In this paper, we document the

The North American Ice Sheet Complex (NAISC; consisting of the Laurentide, Cordilleran and Innuitian ice sheets) was the largest ice mass to repeatedly grow and decay in the Northern Hemisphere during the Quaternary. Understanding its pattern of retr

Glacial advance, occupation and retreat sediments associated with multi-stage ice-dammed lakes: north-central Alberta, Canada
Autor: Jessica M. Slomka, D J Utting
Publikováno v: Boreas. 47:150-174
Ice sheets that advance upvalley, against the regional gradient, commonly block drainage and result in ice-dammed proglacial lakes along their margins during advance and retreat phases. Ice-dammed glacial lakes described in regional depositional mode

Flow-pattern evolution of the Laurentide and Cordilleran ice sheets across west-central Alberta, Canada: implications for ice sheet growth, retreat and dynamics during the last glacial cycle

This paper presents a reconstruction of the geometry, dynamics and flow pattern of the Laurentide and Cordilleran ice sheets along the Albertan portion of the eastern Canadian Rocky Mountains during the last glaciation. Sediment–landform associatio

Reconstructing the confluence zone between Laurentide and Cordilleran ice sheets along the Rocky Mountain Foothills, south-west Alberta

Publikováno v: Journal of Quaternary Science. 31:769-787
Landform mapping near the Athabasca valley was fundamental to determining whether the Late Wisconsinan Laurentide and Cordilleran Ice Sheets (LIS, CIS) coalesced. In this paper we examine the detailed landform record using new LiDAR digital elevation

Advance, deglacial and sea-level chronology for Foxe Peninsula, Baffin Island, Nunavut
Autor: Michelle S. Trommelen, John C. Gosse, Kayla J. Vickers, Brent Ward, Samuel E. Kelley, D J Utting
Publikováno v: Boreas. 45:439-454
The impact of the Laurentide Ice Sheet (LIS) deglaciation on Northern Hemisphere early Holocene climate can be evaluated only once a detailed chronology of ice history and sea-level change is established. Foxe Peninsula is ideally situated on the nor
