Canadian Columbia River Basin Winter 2016-2017: A Late Rally

Guest Post by Ben Pelto, PhD Candidate, UNBC Geography, [email protected] As the summer ticks by and the fall glacier field season approaches, I’ve realized that I never put out a winter 2016-2017 synopsis, so, like the snowfall this year, it’s arrived late.

Bionnassay Glacier Terminus Tongue Detaches, Mont Blanc, France

Bionnassay Glacier drains west from Dôme du Goûter and Aiguille de Bionnassay of the Mont Blanc Massif in France. The glacier has a heavily debris covered terminus and has experienced less retreat from 1980-2010 then other Mont Blance glaciers. Bionnassay retreated 200 m (Moreau et al , 2012), while Mer de Glace retreated 500 m in the interval 1998 to 2008. Gardent et al (2014) observed a 25% decline in …

Auyuittuq National Park Ice Cap Downwasting, Baffin Island

Just south of the Penny Ice Cap on Baffin Island in Auyuittuq National Park there are a large number of small ice caps.  We focus on three of these ice caps east of Greenshield Lake.  The region has been experiencing rapid ice loss, with 50 % of the ice cap area lost in the last few decades (Miller et al, 2008).  Miller et al (2008) also observe that these are thin …

Snow Deficit on Grinnell Ice Cap, Baffin Island, Canada

The Grinnell Ice Cap Is located on the Terra Incognita Peninsula on Baffin Island. The name suggests the reality that this is a not often visited or studied region. Two recent studies have changed our level of knowledge. Way (2015) notes that the ice cap has lost 18% of its area from 1974 to 2013 and that the rate of loss has greatly accelarated and is due to summer warming, …
