Permafrost in some areas of the Canadian Arctic is thawing so fast that it's gulping up the equipment left there to study it.
"The ground thaws and swallows it," said Merritt Turetsky, a University of Guelph biologist whose new research warns the rapid thaw could dramatically increase the amounts of greenhouse gases released from ancient plants and animals frozen within the tundra.
"We've put cameras in the ground, we've put temperature equipment in the ground, and it gets flooded. It often happens so fast we can't get out there and rescue it.
"We've lost dozens of field sites. We were collecting data on a forest and all of a sudden it's a lake."
Turetsky's research, published this week in the journal Nature, looks at the rate of permafrost thaw across the Arctic and what its impact could be on attempts to limit greenhouse gas emissions that cause climate change.

You are probably right on that. I guess there is no law that says the permafrost has to be at the surface. But, back to these researchers - if they set up instruments on solid frozen ground, only to come back a couple months later to find a marsh, they can't be the sharpest tools in the shed. That frozen to marshy thing probably happens every year, and has repeated itself for hundreds, if not thousands of years.

You can't be bothered to read the article, can you? Instead, you would prefer to substitute your ignorance for actual facts. Let me give you a little help:
See that? "days or weeks". This is a change from an annual cycle.
What level of arrogance does it take to substitute your own ignorance for actual reporting?

Maybe it's the word "forest". Some scrub pine and spruce with roots spread out through the top 1 foot of surface soil, just doesn't sound like "forest" to me. I looked at the Denali link posted above. I don't see a lot of "trees" in that wash on the hillside. I see what look like saplings. I gave a link to Adak National forest. 33 trees, after 50+ years, none of them large enough to harvest for a 2x4.
About that supposed arrogance: Do you, or do you not, attempt to reconcile reporting with your knowledge and experience? And, have you never once found proof that a "reporter" was full of crap? Or, is there some kind of magic about a reporter who reports stuff in the name of science? Even given some magic associated with the word science, have you never, ever, even once, found a study in which the researcher did something stupid?
What we know from the story is, some researchers lost some equipment. Something they didn't expect happened, and they lost equipment. What I don't see is corroboration from the natives that ten, or a hundred, or thousands of square miles of permafrost just collapsed in the last year or ten.

Drunken trees - Siberia - 2007 [nasa.gov]
A crater formed in Siberia's permafrost is growing at an alarming rate - 2017 [bbc.com] - has photos, the trees aren't that tundra-small as you imply.
Drunken forest - Alaska 2018 [vice.com] In parts of Alaska, the ground is sinking so much that trees are growing almost horizontally. It's an area scientists refer to as a "drunken forest."
Ummm... do you? 'Cause it seems that you are so full of... answers that you didn't do the most basic google query [google.com]

So, residents of Russia's Siberia, or residents of the US' Alaska can verify that a thousand square miles of Canadian permafrost has thawed out, overnight. Got it.

Shows that's not impossible as you suggest.

Please note, FatPhil, I don't recall saying that it couldn't happen, or didn't happen - I'm QUESTIONING exactly what happened. I have a suspicion that it didn't just suddenly happen overnight.
Note the title of this thread: Idiot researchers. Then ask all the questions a sceptical reader might ask. Were there no signs at all that the area might be subsiding? How experienced were these researchers in the north? Was this actually "permafrost", or might it have been thermokarst? Note that thermokarst is a kind of permafrost, which is already undergoing a thawing cycle. And, what do the locals have to say about it?
Do you suggest that I should read every paper, and believe what it says? Thanks, but no thanks. There have been articles submitted on this site, which community consensus rejects out of hand. Examples? Any environmental study paid for by any of the players in Big Oil.
Just let it go, man. I'm skeptical that knowledgable researchers, experienced in far-north research lost tons of equipment just overnight. It sounds like someone screwed up, and threw excuses into the echo chamber of man-made global climate change.

We've known for awhile that beavers ("Nature's ecologist") have been trying to melt the permafrost to form lakes, etc (homes for themselves and their children):
