"Borrowed" Banner of pirates of the proteome and AUV Clio on the fantail of the Atlantic Explorer in the Sargasso Sea

We heard there were some wannabe pirates at the mass spectrometry conference in Baltimore last summer. Somehow their banner ended up in the Bermuda Triangle... (From one robot to another @evosep.bsky.social, I blame the humans.) #piratesoftheproteome #ASMS2025

Successful dive and recovery to the eddy center, 18 sample depths down to 800 meters deep and engineering tests completed too.

“Blue ocean” 🤣.

I’m untethered! The exact moment it happened with engineer hop.

Here goes Clio humor again lol.

New platform, fresh start! Sigh, I had to lie again.

Happy international cat day! Here is my cat Pintxo the relentless.

Measuring Sr isotopes in assortments of carbonates for the first time. So far so good, but fingers-crossed…. #isotopes #multicollector #MS

Evidence for Hadean mafic intrusions in the Nuvvuagittuq Greenstone Belt, Canada Many questions remain regarding Earth’s earliest crust owing to the rarity of Hadean (>4.03 billion-year-old) rocks and minerals. The Nuvvuagittuq Greenstone Belt (NGB) in Canada may be the only known...

Congratulations Jonathan, Hanika and the team!

How little we’ve seen: A visual coverage estimate of the deep seafloor In decades of deep-sea exploration, humans have observed only 0.001% of the deep seafloor, leaving 66% of planet Earth unseen.

The view of Mont Blanc was fantastic yesterday! #montblanc #chamonix

This is hilarious.

Cover of book "Antarctica and the Earth System"

New book!! 📕

Antarctica is intimately connected to the rest of our planet, affecting climate, ecosystems, cultures and society. Our new book draws together international experts to explore this influence, and to understand what humans are doing to Antarctica (1/n)

Our review article on marine carbon dioxide removal is open access, perhaps useful with carbon dioxide removal in the news again this week

From domain 'geologyscience.com': An image of a blood falls at Taylor Glacier shows dramatic rust-red water flowing from an ice wall. I can't be certain they haven't tweaked the colors, which seem especially vivid compared to others.

At the foot of Taylor Glacier, in Taylor Valley, Antarctica, is a "Blood Falls", an ominous and disturbing natural phenomenon.

First observed by a 1911 expedition led by geologist Thomas Griffith Taylor (for whom the valley & glacier are named), it was originally thought to be red algae, but...

There are many applications of this work, both modern and ancient surface environments, which can be found in the discussion section 😉!

Interaction of metal oxyions and phosphate with carbonate green rust: Insights into Earth’s modern and ancient environments Carbonate green rust (GRCO3) is often found in suboxic and anoxic environments, and is known to be highly reactive towards dissolved metals and other …

Paper alert 🚨 Interaction of metal oxyions with carbonate green rust in seawater is out now! This is one of the few papers that investigated metal uptake with GRCO3 in seawater and conducted 1 year aging experiments!

I need to get up there. I should come by in January!

That’s funny. Hihihihi.

Went for a Sunday stroll today.

Beauty of being a scientist @whoi.bsky.social. You get to enjoy work and the sunset ❤️.
