Scientists retrieved 13 ARMS units from deep reefs off Guam, collecting 2,000 specimens, including 100 species new to the region and 20+ new to science. Sensors show warming even in the twilight zone. It’s the start of a 76-ARMS effort to protect deep Pacific reefs.

Deep-sea ‘hotels’ reveal 20 new species hiding in Pacific Ocean twilight zone near Guam

A transparent goby fish drifted through the darkness, its skeleton visible through paper-thin skin. Nearby, a sea slug wore yellow polka dots like a party dress, while an orange fish with bulging…

Day 27 - Bounded #sciartseptember. In the deep sea a pair of shrimp will begin living in glass sponges and remain trapped inside the sponge once they get larger, the shrimp will be bound to the sponge for the rest of their lives.

Got a little busy today with work, so a little bit of a cheat, but for #sciartseptember prompt niche we have the various animals that call the hydrothermal vents there home, each filling a paticular niche.

The Deep Ones - I’ve been always thinking about a deep sea Cephalopod theme and here it is! Tentacles and appendages are so different when it comes to arranging the composition so it took me a good while, and hopefully it ends up well! 🦑🐙They’re just like from another world💙

Hundreds of thousands of people in Argentina have watched a livestream of a deep sea exploration, partly out of interest in nature and partly as a form of activism as President Javier Milei threatens to cut state-funded science. nyti.ms/45rOOmu

A Starfish Has Captivated Argentina. It Didn’t Ask to Be Political.

A livestream of an undersea project has captivated Argentina as President Javier Milei wields a chain saw on the budget for science.

#WHOI's Johanna Weston is part of a @schmidtocean.bsky.social research mission to investigate the biodiversity of a deep-sea canyon off of Argentina with her zooplankton sampler #DeepZoo! 📲Join millions of Argentinians following SOI’s next Divestream: youtube.com/@SchmidtOcean/streams

This would be a great entry for a coffee table book of on-the-fly field sampling innovations.

🧪🌊🌋⚒️ What do you do when a 2.5-km-deep Pacific Ocean volcano erupts (3rd time in 33 yrs) with the Alvin sub in the water? You pull Alvin fast, coat a weight in Crisco, toss it overboard with a wireline acoustic locator beacon, & pull up fresh lava chips the "old fashioned" way. Specimens on the way😍

**BIG NEWS in the geology world!** For the first time, scientists spotted an active eruption along the mid-ocean ridge!! They visited the hydrothermal vent the day before, where a vibrant ecosystem thrived in the sweltering water. The next day, everything was gone. ⚒️🧪 My latest for @nytimes.com

Volcanic Eruption in Deep Ocean Ridge Is Witnessed by Scientists for First Time (Gift Article)

Researchers diving in a submersible in the eastern Pacific realized that the landscape they had studied the day before had been glassed over by fresh lava.

Very excited this part of my PhD is out 🎉 We describe vent viral and microbial traits that govern viral biogeography and contribute to mounting evidence that these communities are highly endemic, and thus likely vulnerable to disruptive activities like deep sea mining #Microbiome #DeepSeaMining

Harvard redid its whole homepage to push back against the administration’s demands. I mean, this is just a website but I think it’s kind of a great PR move: www.harvard.edu

Hey, that’s my undergraduate advisor! Jill inspired me to take this path in biological oceanography and her phenomenal mentorship is how I got to where I am today.

With a fellow grad student Jill Leonard, I measured the metabolic rate of skate embryos in the egg capsule. They have to pump water through the capsule with the tail. This turns out to be energetically expensive. Making the passive flow from #MyFirstPaper more interesting. 🧪 www.researchgate.net...

Genetic bottlenecks are evolutionary events that reduce the effective size and diversity of natural populations, often limiting a population's ability to adapt to environmental change. Given the accel...

Amidst all the bad news, I still want to share two new preprints from our lab group. The first is led by newly minted Dr. Michelle Hauer, in collaboration with @karthik-a.bsky.social @katiekliermicrobe.bsky.social and @maggielangwig.bsky.social www.biorxiv.org/content/10.1...

Phage interactions may contribute to the population structure and dynamics of hydrothermal vent microbial symbionts

Deep-sea hydrothermal vent ecosystems are sustained by chemoautotrophic bacteria that symbiotically provide organic matter to their animal hosts through the oxidation of chemical reductants in vent fl...

I figured it would be fitting for my first post on this platform to be for #invertefest, featuring some of the commissioned work I have done for scientific conferences. Looking forward to drawing many more inverts this year!

Ascending after a very successful mesophotic dive at Desecheo Ridge! Puerto Rico has welcomed us with abundant and diverse corals and cryptofauna. Excited to see what other communities we will encounter during this expedition with @SchmidtOcean! #DiagnosingDeepCoral

Expedition #DiagnosingDeepCoral is off to a beautiful start! @SchmidtOcean @lehighu

That’s a wrap on the 2023 Lava Watch expedition to the East Pacific Rise! After my first Alvin dive and many fluid and biological samples, we meet our final challenge: returning to single digit temps in the Lehigh Valley.

After a few completed Alvin dives, the @LehighU geochemistry team is getting into the rhythm of the night with many (!) successful vent fluid and biological samples. #LavaWatch23 #NSFfunded

Thrilled to be heading back to EPR 9 50N with @jillmmcd’s geochemistry team, and even more thrilled to be accompanied by HOV Alvin.
