Have you been selected as an Author for the IPCC AR7 and are you planning to attend the Ocean Sciences Meeting 2026? Please get in touch! I am convening an IPCC-focused Town Hall and will invite a panel of Authors to address the scientific challenges for AR7 and answer questions from the community

If i could just ask you all to share again we'd be very grateful, thanks. Almost at the target now!!!

What a blow to Antarctic research in the US and all of us in the international Antarctic science community that rely on the logistical and intellectual infrastructure - sending strength to colleagues affected this 🌊

Important paper published in Quaternary Science Reviews by Anne Leal, Bob Anderson, et al. Their analysis of 231Pa/230Th in the modern ocean shows little relationship to water mass age, complicating Pa/Th as a proxy for past AMOC changes. 🌊🧪 www.sciencedirect.com/science/arti...

Dave Green at the Cavendish Laboratory in Cambridge told me about his colormap "cubehelix". It solves the problem that many color maps use hues like green/yellow for mid values, which appear brighter than red used for high values. Is anyone using cubehelix? 🌊🧪 people.phy.cam.ac.uk/dag9/CUBEHEL...

I was in the NSF building once. I went to serve on a review panel: I and six other scientists put aside our own work to travel to the NSF HQ and evaluate our peers' research proposals, working together for two intense days to prioritize support for the most impactful new science. I'll miss it.

This headline is crazy, but it points out the study from @aoschlies.bsky.social et al. that biotic mCDR techniques like iron fertilization or kelp cultivation could have severe negative consequences for marine ecosystems. The same isn't true for abiotic ones like ocean alkalinity enhancement. 🌊

Read this preprint from @manonberger.bsky.social, Lester Kwiatkowski, @bopplaurent.bsky.social, and me about how if you consider iron limitation, growing seaweed doesn’t work as a CO₂ removal (CDR) technique. 🌊

New work by Lester Kwiatkowski and colleagues suggests that the reduction in coral reef calcification due to climate change may end up enhancing the ocean carbon sink by up to 1.25 Gt CO2 yr-1 by mid century (by even more by 2300) 🌊 www.pnas.org/doi/full/10....

🌊 Happy #WorldOceansDay from SCAR! Today, we celebrate the mighty Southern Ocean—a climate hero that deserves the spotlight. To mark the day, we’re sharing three stunning data visualisations from a past EG-ABI competition, showcasing the impacts of climate change on the Southern Ocean.

Let the 3rd UN Ocean Conference be the conference that makes the difference! 1️⃣ Act now where science is clear 2️⃣ Advance knowledge before irreversible decisions 3️⃣ Turn knowledge into action, and action into justice Do not hesitate to disseminate widely. 2/2 #UNOC3 #OOSC #ScienceForTheOcean 🌊

My co-chair François Houllier and I are delighted with this resounding success, after 2 years of preparation and many hurdles to overcome. The recommendations will be presented to Heads of State and Governments tomorrow, the day before #UNOC starts. #OOSC #ScienceForTheOcean

‼️ Please disseminate widely: the manifesto of the One Ocean Science Congress #OOSC is open for digital signature: forms.ifremer.fr/pdg/oosc-man... #ScienceForTheOcean 🌊

Earth system models are plagued by uncertainties in the response of microbes to climate change. We leveraged metabolic insights from genome scale models when coupled to an ocean model in this new exciting work 🌊 www.science.org/doi/full/10....

As we wrap up the One Ocean Science Congress #OOSC, the message is clear: the need for science-based action for the ocean is urgent. SCOR will join the community of scientists carrying this message into the #UNOC3 next week. Review SCOR-related events at scor-int.org/2025/05/28/s...

"Iron fertilization is notably 'much less effective than initially imagined,' warns @bopplaurent.bsky.social. It is not as sustainable as hoped and can lead to a decrease in the amount of oxygen below the surface, which is harmful to species." 🌊

Out today in Nature, our paper on the drivers of the record 2023 summer heating of the North Atlantic. Temperatures warmed to record levels in just a few months. The impacts on climate & ecosystems were severe. A thread on how this work came about and what we found.👇👇🧵 www.nature.com/articles/s41...

🌊Float of the Month. The BGC-Argo array in May 2025! With ships, it took decades to collect the data to visualize the chemistry and biology of the ocean interior. Now we can do it monthly, realtime, quality controlled. Access is easy with webODV. This is going to change things! #UNOC3 #OneArgo

@manonberger.bsky.social showed at #OOSC that if iron limitation is considered, there’s nowhere in the ocean where it’s suitable to grow kelp for CO₂ removal (CDR). Stay tuned for the paper.
