Two days of deep dive into in the science of the Helmholtz POF Topic “Marine and Polar Life” during the Topic 6 Symposium in Oldenburg: fruitful scientific exchange and plenty of opportunities to get to know each other. Thank you for coming and contributing, @awi.de & @geomarkiel.bsky.social. 1/4

So excited to be at #ESEB2025 presenting poster 221 today!☀️ Check out our chromosome-level genome of Bostrychia, a red alga from the complex Ceramiales order, revealing massive genome expansion by giant Plavaka DNA transposons, the evolution of expanded gene families and UV sex chromosomes!

Startschuss für das Programm zu The Ocean Race Europe 🌍 🌊 Die Kiellinie ist momentan nicht nur Segelmeile, sondern auch Schaufenster für Meeresschutz und Meeresforschung. Kommt uns im Ocean Live Park besuchen! Zu unserem Programm: www.geomar.de/service/vera... 📸 Lukas Schröder, GEOMAR

🌊🌿🧬 Looking for a PhD candidate 🧬🌿🌊 Exciting opportunity to work with us @geomarkiel.bsky.social on heat adaptation of Baltic Fucus, coupling genomics with experimental approaches! Experience in molecular biology and bioinformatics very welcome Closing date 31 August www.geomar.de/en/karriere/...

Busy week Fucus sampling with our colleagues @gloriareithmaier.bsky.social @lies-nerd.bsky.social @karikaphegyi.bsky.social and lots of others for #Fubluc and getting ready for outreach with kids for #TheOceanRaceEurope @geomarkiel.bsky.social

Doctoral position on genomic basis of Fucus (brown algal) local adaptation - join our exciting #Fubluc team! Fully funded for 3.5 years & we also consider candidates with strong molecular or bioinformatic skillls but no marine / algal experience, see www.geomar.de/en/karriere/...

Even though sea stars were critically underrepresented, I had a blast at #ITRS2025 in Brest! 🌊🌡️⭐ First conference, first Bluesky post and somehow, I now have a soft spot for kelp.🌱 Shoutout to @lies-nerd.bsky.social , @frankmelzner.bsky.social , Mark Lenz, and all the lovely people I got to meet!

Had too much fun at #ITRS2025 to be active online, so Hi from the early train leaving Brest! It was an absolute pleasure to see so many colleagues, present novel results and represent team @geomarkiel.bsky.social with @frankmelzner.bsky.social @katjasee.bsky.social Looking forward to next time!

Anne Salomon taking us on a marvelous deep dive through time, recontextualising people’s relationship with coastal ecosystems #ITRS2025 #marineecology 🧪🦪🌱🎣 @ifremer.bsky.social @ofbiodiversite.bsky.social @sbroscoff.bsky.social @thembauk.bsky.social

Still 5 hours left to meet us and various marine critters on board if RV Alkor & the Kiel Outdoor Benthocosms with an experiment on carbon storage potential of brown algae with @lies-nerd.bsky.social @geomarkiel.bsky.social #FUBLUC - and the sun is out now!

A study confirms what we have long argued: the spectacular Atlantic 'cold blob' is the result of a slowing of the Atlantic overturning circulation #AMOC, which transports warm waters into that region. That's the only part of Earth that resisted #globalwarming. 🌊 www.sciencedaily.com/releases/202...

From disappearing #seaweed beds, to invasive #sargassum blooms… fascinating article from @financialtimes.com, featuring our Dr Yanna Alexia Fidai, which examines how human activity is disrupting the balance of marine algae across the globe: www.ft.com/content/b815...

Boosting thermal tolerance could help cold-water kelps persist in areas that are getting warmer. The challenge is how to reach a higher tolerance but it shows that it is worth the effort. Climate change mitigation is key onlinelibrary.wiley.com/doi/full/10....

Finally some practical #bioc-202 work for our MSc students in Biological Oceanography at #Geomar! Exposing bladderwrack populations to heat stress regimes to study photophysiology & local adaptation! Real science projects to support meadow conservation #ANK #FUBLUC with @lies-nerd.bsky.social

This statement about the transphobic Supreme Court ruling by the UK's Crab Museum (yes a museum about crabs) is better than 99% of the statements I've seen on the topic www.crabmuseum.org/visit 🦀🦀🦀🦀🦀🦀🦀🦀

#PhycologyFriday, from one of my favourite spots, from the wave exposed shores of northern Norway - with a mosaic of Laminaria digitata and Alaria esculenta, with some Fucus serratus, Palmaria palmata and other macroalga in between.

Spent the day at the @montereybayaquarium.org and was blown away by the massive exhibits, especially the giant #kelp cathedral 😍 Inspiring to see marine sci-comm done expertly, and I loved the hands-on science for the little ones! My lesson of the day: Fucus distichus grows also in the Pacific?!

and another 5-yr (!) postdoctoral position at GEOMAR Kiel on advancing seagrass assisted evolution, see details and link to apply www.geomar.de/en/karriere/.... Omics and pop genetics knowledge required, seagrass and coastal ecology desirable. @geomarkiel.bsky.social DM me for inquiries

The GEOMAR seagrass team is hiring. Time to make coastal restoration long-term sustainable. A fully funded 4-yr PhD position on eelgrass seascape genomics in the Baltic Sea, further details see here www.geomar.de/en/karriere/... @geomarkiel.bsky.social DM me for inquiries

🚨Preprint Alert🚨 I'm really happy to finally share our exploits in red algae and introduce the wider community to Bostrychia, the new model system we have been developing to tackle the molecular biology of red algae. Isn't she a beauty? Thread below 🧵 1/8 www.biorxiv.org/content/10.1...

New paper out! 🎉 #Kelp #carbonbudget dominated by carbon loss processes under #oceanwarming 🌡️. Differential effects on carbon allocation depend on population origin. #Laminaria @lies-nerd.bsky.social www.sciencedirect.com/science/arti...

We conducted a 'classic' kelp canopy removal exp in mixed Laminaria forests in southwest UK. Results show that loss of canopy increases 5-fold the light reaching the reef which leads to 7-fold increase in understorey algae & 9-fold increase in kelp recruits; ms: www.sciencedirect.com/science/arti...

Where are all the field studies? This ⬇️ important but rather depressing paper describes how conducting, & crucially initiating, field studies is becoming harder & rarer. A short 🧵 (and a call for more fieldwork) www.cell.com/trends/ecolo...

Bull Kelp (Nereocystis leutkeana) portrait for #PhycologyFriday

New paper alert! Partially sex-reversed giant #kelp gametophytes allowed us to investigate the transcriptomic machinery behind sexual differentiation in the haploid U/V sex chromosome system of brown #algae. Check out the open access paper here: authors.elsevier.com/sd/article/S...

Very happy to share my PhD paper! www.nature.com/articles/s41...

First post! New Letter. Kelp forests support biodiversity & livelihoods along 30% of the coasts. However, ~3% are fully protected despite being highly threatened. We call for nations to protect 30% of their kelp by 2030. @hugepossum.bsky.social @uq-cbcs.bsky.social science.org/doi/10.1126/...

Ok let's set the vibe over here
