What’s in our backyard? 🌳🌸🐚

This week @theberkeley_bda S3 students joined our team to answer this question, looking at native and invasive plants and animals at Spittal Pond. 🌱

#stemeducation

It's hard to grasp how large this grouper is until you see it in comparison to the ship's toilet on the left.

This appears to be an Atlantic goliath grouper or 'itajara' (Epinephelus itajara). They can reach 800 lbs (350 kg) & 8 feet long (2.5 m)

Let's talk about these gentle giants.

Ocean Bacteria Work the Night Shift | BIOS New study finds nighttime peaks in bacterial activity and carbon cycling in the ocean

A new study shows that ocean bacteria are busiest at night. These tiny organisms play a major role in moving carbon through the ocean, and scientists have found they do much of that work during the night shift! 🌒 🦠🔬

New Study Using Ocean Gliders Uncovers Clues About Carbon Cycling in the Sargasso Sea | BIOS Hourly measurements show when and how the ocean produces, recycles, and exports carbon — and why salps matter more than we thought

Tom and Julie went out a few days ahead of the rest of the team to do a last minute check that all the islands and beaches and bars existed.

BIOS, our home for 6 weeks this summer.

#exoCeanadvent Day 10: As winter creeps into Provence we remember warmer days from our fieldwork in Bermuda. We stayed with the lovely folk at @biosstation.bsky.social, like @blancobercial.bsky.social who helped us to look for different foraminifera to catch, than our usual Mediterranean stuff.

POV: You’re diving on coral reefs, learning marine ecology, and making lifelong friends and future colleagues while spending 15 weeks living on a research station in Bermuda. 🇧🇲

Predicting the Arrival of the Portuguese Man o' War | BIOS Scientists are studying how winds, currents, and climate change influence the drift of the Portuguese man o' war in an effort to forecast its seasonal movements

@biosstation.bsky.social publica el trabajo que está desarrollando un equipo internacional de científic@s, también de nuestro centro, para predecir la llegada de #Physaliaphysalis o #carabelas_portuguesas y determinar cómo afecta el #CambioClimatico a sus trayectorias.

From Online Learning to Ocean Exploration: Going to Bermuda | ASU Online Online ocean futures students at Arizona State University can gain hands-on ocean research experience at the Bermuda Institute of Ocean Sciences.

“In Bermuda, you’re going to get in the water & see what it’s like to work in the ocean”

Gain hands-on experience through courses like Coral Reef Ecology, Marine Molecular Ecology & Research Diving Methods study abroad.

More #NASA #PACE work onboard the RVAE!

This time #ASU graduate student Ceridwyn Hunter, part of the Hochberg lab @biosstation.bsky.social, takes radiometric measurements at #BATS. She takes these measurements when the satellite is passing right over us!

During the C-CoMP March Cruise, Clio, the biogeochemistry AUV, was used to collect particle samples for proteomics and metagenomics from various depths within the water column. Check out some of these photos of Clio in action:

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

During our March cruise, C-CoMP researchers deployed SVP drifters during diel sampling. The drifters enabled tracking/sampling the same parcel of water in a Lagrangian approach, aiding efforts to capture diel microbial signals from the same water over time!

And that’s a wrap 🎬on C-CoMP Cruise 2 🚢! We (C-CoMP + AE) accomplished an impressive feat - 95 CTD casts, 110,778 L of sw filtered with @clio-thebgcauv.bsky.social, eddy sampling, & 9 exp types across 3 locations - to characterize marine chemical currencies & microbes!

Hard-Fought Treaty to Protect Ocean Life Clears a Final Hurdle

Hard-Fought Treaty to Protect Ocean Life Clears a Final Hurdle www.nytimes.com/2025/09/19/c...

Nations ratify world's first treaty to protect marine biodiversity in international waters A major agreement to protect marine diversity in the high seas was struck Friday when Morocco became the 60th nation to sign on, paving the way for the treaty to take effect next year.

The High Seas Treaty is the first legal framework aimed at protecting biodiversity in international waters, those that lie beyond the jurisdiction of any single country. https://to.pbs.org/3VKRnMh

A big thank you to all the folks at @biosstation.bsky.social, @whoi.edu, and the crew and Captain of the R/V Atlantic Explorer for making this research and cruise possible!
