The fate of silicon in the ocean is something we surprisingly still trying to wrap our heads around. Part of it is integrated into the shells of marine organisms (e.g., diatoms), but when they die, some dissolves back, and some apparently turn into clay. 🧪🌊 Link: www.science.org/doi/full/10....

Looking smart post match!

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. 🌊
