Bacterial extracellular vesicles exhibit distinct functional potential across biogeographic provinces of the South Pacific Ocean

Abstract. Bacterial extracellular vesicles (BEVs) are nanoscale membranous structures released by diverse types of bacteria, and are capable of transportin

📌 New publication in Nature Geoscience by Amano et al., reveals that heterotrophic bacteria substantially contribute to oceanic dissolved inorganic carbon fixation via anaplerotic pathways, accounting for an estimated ~17% of dark DIC fixation and a significant global carbon flux.

📌 New publication in Limnology and Oceanography shows that fluorescent proteins in Madracis corals have species-specific, structurally distinct distributions that correlate with symbiont localization and light exposure, suggesting they contribute to ecological adaptation and species differentiation.

The 3rd Symposium on Oceanography has successfully concluded, bringing together excellent speakers for a vibrant exchange of ideas in ocean science. Thanks to everyone who contributed to making this year’s event a stimulating and collaborative experience.

The Microbial Oceanography Vienna and Marine Microbial Biogeochemistry groups are hosting the 3rd Mini Symposium on Oceanography on 7 May 2026. 📍University of Vienna Biology Building (Seminar Room 3.1) 🕥 10:30 am

I am thrilled to announce that the BEVocean research project, which is funded by the Austrian Science Fund (FWF), is officially starting today! @microbialoceanv.bsky.social @stevenbiller.bsky.social @matthiaswietz.bsky.social @fwf-at.bsky.social @univie.ac.at @bokuvienna.bsky.social

Science thrives when women stand together! MOVIE proudly celebrates the International Day of Women and Girls in Science #IDWGS with this inspiring group of female scientists driven by curiosity, strong voices and an amazing spirit of teamwork. #womeninSTEM

The @microbialoceanv.bsky.social group hosted a CARD-FISH training workshop led by Chie Amano, brining together members of the @univie.ac.at Bio-Oceanography and Marine Biology unit for deep dives into single-cell microbial ecology.

Very happy that our paper was published in Limnology & Oceanography #ASLO_LO Huge shoutout to my co-authors🫰 & big thanks to reviewers and editors! May the year keep up this energy 🙌 @microbialoceanv.bsky.social @aslo.org @davehambright.bsky.social aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

Major contribution of particle‐associated microbes to deep‐sea organic carbon degradation

The biological carbon pump mediates the export of particulate organic carbon from the euphotic zone to the deep ocean, where it provides the base of the food web. Although deep-sea microbial metaboli...

The Microbial Oceanography Vienna group wrapped up the year with a cozy Christmas dinner 🎄✨ Grateful for good food, great company, and another year of science together 🌊

Manuela Quiroga Pérez successfully defended her master thesis, where she investigated the microbiomes of restored and native Atlantic soft corals. Congratulations! 🪸

Thrilled to welcome Dr. @valdeanda.bsky.social as Senior Research Fellow! Valerie is an Environmental Microbial Bioinformatician studying microbial metabolism in extreme environments, combining fieldwork, experiments, and computational modeling while championing equity and inclusion in science.

Wrapping up an inspiring week at #SAME18 in Barcelona. The MOVIE group was proud to contribute with talks and posters, sharing ideas, connecting with colleagues and learning from so many brilliant presentations. Grateful to @same18-bcn.bsky.social for the engaging discussions and vibrant atmosphere!

@zihaozhao.bsky.social gave an enthralling presentation on “Niche partitioning of marine microbiota in deep-sea organic matter cycling”. #SAME18 @same18-bcn.bsky.social

Eduard Fadeev delivered an engaging presentation on “Marine bacterial extracellular vesicles - elucidating the functional potential of ubiquitous nanoscale structures at the oceanic scale.” #SAME18 @same18-bcn.bsky.social

Delighted to present part of my #MSCA #MIMEPOC fellowship research on “Shaping deep Antarctic carbon and nitrogen flux: the role of particle-associated microbial processes.” #SAME18 @same18-bcn.bsky.social

@marinelena.bsky.social gave a compelling talk on “Distinct communities of particle-associated microbes drive organic carbon degradation in the dark ocean”. #SAME18 @same18-bcn.bsky.social

Chie Amano delivered a fascinating talk on “Microbial incorporation of methionine and leucine in the pelagic ocean”. #SAME18 @same18-bcn.bsky.social

On Thursday 31 of July the MOVIE group together with collaborating scientists departed from Reykjavik aboard the R/V Pelagia @niozsearesearch.bsky.social to kick off the NEREIDES expedition.

In just a few weeks, the MOVIE group sets sail on a 1-month research cruise aboard the R/V Pelagia in the Atlantic Ocean! Our equipment is packed and shipped, and the count down has officially begun as we get ready to join the NEREIDES cruise. Stay tuned for updates ⛴️ 🌊🦠

Linn Ødegaard Yttrelid successfully defended her master thesis exploring Community dynamics of Symbiodiniaceae and Bacteria in reef-building corals!

Mirjam Aubert successfully defended her master thesis, investigating "Ecological relevance of extracellular vesicles in the Northern Adriatic Sea." Congratulations!

Happy birthday Gerhard!

We are thrilled to have successfully concluded the 2nd mini Symposium on Oceanography. Thank you to our outstanding speakers and engaged participants for making this event a hub of scientific exchange and inspiration!

The Microbial Oceanography Vienna (MoVie) group is hosting the 2nd Mini Symposium on Oceanography on 30 April 2025. We’re delighted to invite you to attend a series of fascinating talks by invited scientists - all ocean enthusiasts are welcome! 📍University of Vienna Biology Building 🕚 11:00 am

Marilena Heitger @marinelena.bsky.social attended the ASLO 2025 @aslo.org Aquatic Sciences Meeting in March 2025 in Charlotte, North Carolina, USA, to present her work on microbial activity on particles in the meso- and bathypelagic North Atlantic.
