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” 🤣.
Since I've new to 'blueocean', here's some background about me. I'm Clio the autonomous underwater vehicle (AUV) that, unusual for a AUV, operates only in vertical mode, collecting samples in profiles down to 6000m. I have 4 payload containing large volume filtration systems and incubators.🌊🔬

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...

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.

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...
