Huge paper for the Arctic Ocean published today in @science.org - a new 30,000 year history of Arctic Ocean sea-ice cover reconstructed from the accumulation of cosmic dust-derived helium-3! www.science.org/doi/10.1126/... (1/n)

Check out our latest work, led by Jon Jung, Ph.D. student in the @amglab.bsky.social at @mpic.de: www.nature.com/articles/s41... Here we show that the supply of excess phosphorous from accounts for the majority of observed Sargassum variability since 2011. 🌊 🧪 #Paleosky #CoralReefs

Next talk by Iliana Baums @ibaums.bsky.social on "Reconstructing historical population dynamics of corals" @hifmb.de @marumunibremen.bsky.social

Chris Voolstra @reefgenomics.bsky.social kicking off the 2nd day of the #SPP2299 "Meeting & Status Seminar 2025" with a Perspective Lecture on "The future of reefs and reefs of the future"

First Keynote at #SPP2299 "Meeting and Status Seminar 2025" by Andrea Grottoli @andreagrottoli.bsky.social on "Leveraging coral biology, technology, and research networks to save coral reefs" in Bremen @marumunibremen.bsky.social

Another cool paper coming out of @amglab.bsky.social. Led by Tanja Wald, here we present basin-wide profiles of Mediterranean nitrate N/O isotopes, and show that this distribution can be explained by a combination of nitrogen fixation and anthropogenic nitrogen deposition: dx.doi.org/10.1029/2023...

🧪

Check out this exciting application of N isotopes from colleagues Tina Lüdecke and Jen Leichliter (@jenniferleichliter.bsky.social) and others just out in Science: Australopithecus at Sterkfontein did not consume substantial mammalian meat www.science.org/doi/10.1126/...

New Paper Alert! Check out a recently published study around on decadal oscillations in the world's largest oxygen-deficient zone. This research, by Nicolas Duprey from MPI for Chemistry, uses nitrogen isotopes in corals skeletons to understand natural climate variability of the Pacific ODZ. 1/n

Last, a set of observations detailing a massive cold-bleaching and mortality event of mesophotic reefs that we observed in 2023 onboard S/Y Acadia at Clipperton Atoll in the Eastern Tropical Pacific: www.sciencedirect.com/science/arti...

Hot off the (e-)press, a study in Science led by Nic Duprey showing that the variability of the world's largest Oxygen Deficient Zone over the last 80 years is tightly linked to Pacific Decadal Variability: www.science.org/doi/10.1126/...

We've had a couple cool things come out of the lab lately, and I wanted to share. First, check out this paper from Jon Jung et al. in Nature showing geochemical evidence for coral symbiosis on Devonian reefs: www.nature.com/articles/s41...
