Does ocean model resolution change how fast CO₂ equilibrates with the air? In our new study with @bachlennart.bsky.social and @mtyka.bsky.social, we found small resolution effects but large inter-model spreads —highlighting the next goal for improving mCDR predictions. link: doi.org/10.1029/2024...

Our new paper with Mengyang Zhou, Elizabeth Yankovsky, and Dustin Carroll is out as a preprint: egusphere.copernicus.org/preprints/20... "Substantial inter-model variation in OAE efficiency between the CESM2/MARBL and ECCO-Darwin ocean biogeochemistry models"

🚨 New paper alert 🚨 We developed the new PanAntarctic model and assessed the sensitivity of Antarctic Bottom Water (AABW) formation and export to horizontal model resolutions of 1/10°, 1/20° and 1/40°. Open access paper in JAMES: doi.org/10.1029/2024...

Would marine calcifiers such as coccolithophores benefit from changes in carbonate chemistry under ocean alkalinity enhancement? @bachlennart.bsky.social and I tried to answer this question in a new natural analogue study out now in Nature Geoscience! @naturegeosci.bsky.social 🌊🧪 rdcu.be/d9zdH 1/10

🚨 New preprint! 🚨 We explore how model resolution and different models affect air-sea CO2 equilibration timescales. Turns out, resolution matters more in some regions than others — but differences between models generally matter more 🌍🌊 Check it out here 👉 essopenarchive.org/doi/full/10....

New paper by @midwayxie.bsky.social with CCRC co-authors Hannah Dawson & @christinaocean.bsky.social: Waters subducting into the deep ocean near Antarctica can sequester CO2 for centuries. By analysing how long these waters stay in the euphotic zone we found that light is limiting CO2 fixation.
