So pinni-precious. 🥺🦭 Pupping season is winding down as summer begins, but the harbor seal spectacular is just getting started! So mellow out, settle in, and enjoy your day on the bay with the chill vibes of a sleepy harbor seal. 🏖️☀️

New paper out in the lab from Travis Mellett on how iron impacts organic carbon consumption by heterotrophic bacteria in the mesopelagic www.nature.com/articles/s41...

A sad day. Jorge Sarmiento, one of the greats in ocean science, passed away today. Jorge was a model leader; thoughtful, compassionate, and an excellent scientist. His leadership of @soccomproject.bsky.social transformed @bgc-argo.bsky.social into a global system.

🚨Paper alert 🚨 Our paper is out on “Revisiting the greatness of Earth’s great oxidation.” Please take a look 👇!

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

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) www.routledge.com/Antarctica-a...

Our review article on marine carbon dioxide removal is open access, perhaps useful with carbon dioxide removal in the news again this week www.annualreviews.org/content/jour...

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...

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!

Went for a Sunday stroll today.

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