🪸Our new paper led by Lily Böhringer is out: Benthic megafauna from @awi.de #HAUSGARTEN Observatory in the #Arctic #DeepSea went through significant changes. From 2002-2021, selected taxa populations declined ranging from 28% for crinoids to 93% for soft corals.

Outreach is a lot of fun when the lights go out 👀. We took part in Night at Aquarium on February 20 here in Bergen sharing all we know about Arctic deep sea worm forests and chemosynthesis to curious kids and families 🐟🪱
Excited to share that @michelle-hauer.bsky.social's paper with @katiekliermicrobe.bsky.social @maggielangwig.bsky.social @karthik-a.bsky.social on phage interactions with chemosynthetic symbionts was published today. #NSF and @schmidtocean.bsky.social supported. academic.oup.com/ismecommun/a...

Flyer with details on the workshop and pictures of two cumaceans. It says: DESCRIPTION: Join us to learn about the fascinating peracarids known as comma shrimp! This workshop will introduce cumacean collecting and identification with a mix of field trips and lab work, working with a combination of live specimens and preserved specimens. Outcomes for trainees include training in morphology and taxonomy of Cumacea, and training in collection, sorting, preservation, and photography of specimens. The course is suitable for advanced undergraduate to graduate students, post-docs or professionals who are interested in learning about and working with cumaceans. DATES: August 3-7, 2026 LOCATION: Natural History Museum of Los Angeles County REGISTRATION: No course fee, lodging and food covered. Accepted students will need to cover their own travel. INSTRUCTORS: Dr. Sarah Gerken, Dr. Kevin Kocot, Dr. Les Watling APPLICATION: Please e-mail your CV, 1 letter of recommendation, and a 1 page statement explaining your background and reasons for taking the course to peracaridabackbone@gmail.com by March 15, 2026 For more information, see www.peracarida.org
ICYMI: The next Confusing Crustaceans taxonomy workshop is Aug 3–7, 2026 at NHMLA!

"As whale populations continue to struggle, a decline in whale falls is reported to have reduced the biodiversity of deep sea ecosystems – and has likely contributed to the extinction of species before we ever knew of their existence." @kathla.bsky.social

🔬 Scientist: Gaya Marine biologist and IMBRSea graduate, researching the impacts of deep-seabed mining on meiofaunal communities in the Pacific. With 100+ days at sea across the Indian, Pacific, Atlantic, and Arctic Oceans, he combines field experience, peer-reviewed research, and global science communication on deep-ocean biodiversity and mining risks. 🎨 Artist: Delphine Creating a series of oil paintings inspired by life in the Clarion-Clipperton Zone, alongside custom coloring plates featuring deep-sea creatures. Printed on art paper for children to explore and paint, these works invite young minds to discover deep-sea ecosystems through imagination and scientific insight, fostering connection, awareness, and stewardship for one of Earth’s least understood environments. 🤝 Together, Oceans Unmined brings art and science into the classroom, empowering the next generation to understand and care for the deep ocean.
Detail of an oilpainting of a Hyalonema. Hyalonema species are deep-sea sponges famous for their long, twisted silica spicules that form a flexible “glass rope.” Found at depths of 200–2,000 m, they anchor themselves into soft sediments while their upper body filters microscopic particles from the water. Their intricate glassy skeletons are among the most beautiful natural structures found in the deep ocean. On the long stalk live tiny polyps.

MicroSEA (Microbial Sea Eukaryotes) course is a one-week, field-based summer school to train early-career researchers in the diversity, ecology, and single-cell biology of marine protists. MicroSEA course integrates lectures, field sampling, and lab-based practicals in advanced techniques, such as flow cytometry, microscopy, culturing, and molecular analysis. The main objectives of MicroSEA course are: Fostering a deep understanding of marine protist diversity, ecology and biology; Providing hands-on training in advanced single-cell methods that are not commonly available in university programs; Building participants' confidence in designing and conducting research projects from field to data analysis; Promoting international collaborations and peer networking among students and speakers/trainers. The course will take place at the Station Biologique de Roscoff - SBR (France) - 7th to 12th of June, 2026 (arrival on the 6th, departure on the 13th). 20 participants will be selected, including 10 from EuroMarine member institutes. https://opbc.sciencesconf.org/
Protist lovers: Please apply for a week of rhapsody! Learn by doing:
