Playing spot the pebbles in the very last meter of ice drilled at Skytrain Ice Rise (~650 meters deep) with @wacswain.bsky.social and PhD student Yu Huang @bas.ac.uk @cambridge-earthsci.bsky.social @gatescambridge.bsky.social

Tried the new tool in Google Scholar. Not super interesting, IMHO. www.nature.com/articles/d41...

I did, however, find this correlation with life 🚼, lab 🏗️, and other 🦠 events quite convincing. 😂

Been watching this for years.

Planning logistics and this is my go to reference for how many ice core boxes can fit in a Eurocopter AS350.

...and the number of dudes needed to stand around looking concerned.

New Paper Alert: "Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis"

ALT title according to the internet when it found a picture of Nick on field work: "Miniature man found in average-sized Geode."

That would have to Greenland. That said, I have stumbled across a mummified penguin when hunting for old ice in the Dry Valleys of Antarctica.

Colour is just depth. Changing the colours by age (linearly) would be tricky as the age of the ice increases rapidly at the very bottom of an ice core. And unfortunately we can't make an accurate map of those ages without more ice cores :)

Updated a classic.

Glaciers in California’s Sierra Nevada are likely disappearing for the first time in the Holocene The projected loss of glaciers in California’s Sierra Nevada is likely unprecedented in at least the past 30,000 years.

The Sierra Nevada’s glaciers—now projected to disappear by 2100 CE—have never before vanished throughout human history in the Americas.

Speleothem evidence for Late Miocene extreme Arctic amplification – an analogue for near-future anthropogenic climate change? Abstract. The Miocene provides an excellent climatic analogue for near-future runaway anthropogenic warming, with atmospheric CO2 concentrations and global average temperatures similar to those projec...

Afternoon folks. I'm delighted to announce our manuscript "Speleothem evidence for Late Miicene extreme Arctic amplification" was published online today. Happy reading! @speleoseb.bsky.social @thomasopel.bsky.social cp.copernicus.org/articles/21/...

Your Zodiac Sign Is 2,000 Years Out of Date Over millennia, our view of the stars has shifted, because of Earth’s wobble. It may be time to rethink your sign.

I promise to write a serious thread of what (IMHO as Peisong's advisor) is an innovative analysis. This will have to suffice for now.

As someone who routinely melts ice in vacuum (or rather with tiny amounts of air), I can confirm that this is true.

Nat Geo would kill for legit science-driven adventure like they found in “For Winter,” over content less credibly grounded in pursuit of knowledge +humans pushing limits. Instead they’ve (Disney?) gotten cold feet & deeply disrespected my colleague Ali & her family. defector.com/why-did-nati...

Probably should have cleaned the source more often but I’ll let it slide given that the guy basically invented mass spectrometry.

Awesome. You should ask your ice core folks for some bubbly ice to see if it melts faster. 😜
