April 2017 – My predecessors and I have been collecting climate change-related data in the Mackenzie Mountains since 1990. In this Earthwatch webinar I explain why each year of monitoring is crucial and why Earthwatch volunteers are so important to this effort. Always remember: ice melts, but permafrost thaws!
December 2016 – Here's a follow-up to a blog post I wrote for the Mountain Research Initiative based out of Switzerland, You can find it here, along with other interesting blogs on work in mountainous regions here:
June 2016 – Time-lapse of palsa thaw and disappearance from 1944 to 2010 in the western Mackenzie Mountains. Upper panel: site Hare Foot (74% aerial loss). Lower panel: site Goose flats (90% aerial loss). The 1944, 1949, 1974, and 1981 images are from aerial photographs and the 2010 image is from WorldView satellite imagery:
March 2016 – This time-lapse video was recorded over two winters in Churchill, Manitoba, from September 2014 to February 2016. The tree islands seen in the video act, as “big catcher’s mitts for the snow.” Churchill sees an average of 50 cm of precipitation each year, and about 25 cm of that comes from snowfall in the winters. While the area is pretty dry, the wind can move the snow into the “mitts” the trees form, causing snow accumulation that can reach over 2 meters. The snow in 2016 was 52% more shallow and 30% less dense compared to the 2004 to 2015 mean.
March 2016 – Working with the Mountain Research Initiative based out of Switzerland, I've written a blog post on citizen-scientist monitoring of treeline and permafrost in northern Canada. Check it out, along with other interesting blogs on work in mountainous regions here: http://www.blogs-mri.org/?p=1049
March 2016 – The Churchill Northern Studies Centre in northern Manitoba posted a video of some of my timelapse snow monitoring across the forest-tundra. In addition to providing a daily record of snow depth and plant phenology, the images make for a very cool look at changing subarctic seasons! Check it out here with music added for dramatic effect:
November 2014 – Boston, MA: Dr. LeeAnn Fishback and myself were invited to give a talk on doing Earthwatch citizen science in a really "cool" place. It was the clicker that malfunctioned, I swear! https://www.youtube.com/watch?v=oYc1bdfumTg
September 2006 – Ryan Murdock from Outpost Magazine published this article about hiking the Canol Heritage Trail. We crossed paths briefly at the start of the hike and chatted over a pot of tea at mile 222.
