Comparing thaw probing, electrical resistivity tomography, and airborne lidar to quantify lateral and vertical thaw in rapidly degrading boreal permafrost
Abstract. Permafrost thaw across Earth's high latitudes is leading to dramatic changes in vegetation and hydrology. We undertook a two-decade study near Fairbanks, Alaska, to measure permafrost thaw a...

Overwintering ‘zombie fires’ aren’t doing what we thought they’d do
A major new study of NWT wildfires that smoulder through the winter surprised the scientists involved and has some lessons for the territory's firefighters.

Northern soil microbes staying up all winter
We can’t see them, but there are more microbes — tiny fungi, bacteria, worms and other living things — in a teaspoon of soil than there are people on Earth.

Green-up turns white: Bonanza Creek LTER recorded this year’s green-up date in Fairbanks as May 2. Since 1976 researchers have recorded green-up when a hillside of birch and aspen trees near the Univ. of Alaska Fairbanks shows a faint green flush. Today the new foliage hides under fresh snow!

Wow, what a great paper. Last week I was just teaching about how climate change may shift the temperate/boreal ecotone Eastward (in principle), so this will be a fantastic data paper to pass on and draw from in the future.
