Today we cored to 3.77m/5m into a burned lithalsa - a ridge/hill cored at depth by nearly pure ice, formed during slow downward growth of permafrost into glaciolacustrine sediments left in the Yellowknife area following the recession of Glacial Lake McConnell. Fun! #geoscience #cdnsci #permafrost

Permafrost soils store large quantities of organic carbon and are often portrayed as a critical tipping element in the Earth system, which, once global
scienceblog.comCanada’s most iconic pingo now fits on a desk! Check out this 3d printed model of Ibyuk pingo, based on structure from motion data collected by NRCan scientists. Ibyuk is ~305m wide at its base and 70 m tall, and being a pingo is cored by pure ice! #scicomm #permafrost

Ground Ice Map of Canada v. 2.0 planning is in the works. The map below will be significantly improved with this update. It will take a fair amount of time and is a side project due to other program commitments #permafrost #cdnsci

Which carbon is the oldest in permafrost soils? …. It is pyrogenic carbon and the leftover from wildfires 🔥🌲

Al langer wordt hiervoor gewaarschuwd. Vanuit de ontdooiende #permafrost (klimaat verandering) komen extra broeikasgassen m.n. #methaan vrij die het #broeikaseffect extra versterken. Ook vanuit de diepzee bodem dreigen grote hoeveelheden methaan vrij te komen.

From the archives (Dec. 2021). Like "The Blob" (1958) it's gigantic and utterly unstoppable unless it can be frozen. As of two years ago it was less than 10 feet from engulfing the Dalton Highway in Alaska. #permafrost #daltonhighway #frozendebrislobe #thaw #alaska

Interesting, but contrary to the article, ice and soil wedges on Earth occur in far more places than Greenland, Iceland, and Antarctica. There are way more in Canada/Russia/Alaska and far larger forms. #earthsci #permafrost

The newfound honeycomb fractures are the "most compelling evidence to date" that Mars was tilted more extremely than it is today.

Widespread permafrost thaw is occurring in northwest Canada. A thread breaking down some findings from our latest Open Access article #cdnsci #earth-sci #permafrost #geomorphology agupubs.onlinelibrary.wiley.com/doi/full/10....
Permafrost thaw and ground surface subsidence are widespread in northwest Canada
Active layer thickness (ALT) measurements poorly represent the magnitude of permafrost thaw in ice-rich settings

Here’s what a core of ice-rich permafrost looks like (from summer 2022). Ice lenses and layers in excess of the soil pore space are clearly visible. It’s this “excess ice” that causes significant issues for buildings/roads etc when permafrost thaws. #earth-sci #geology #permafrost #cdnci
