A new paper, led by GO-BGC researcher @koelling.bsky.social, using @bgc-argo.bsky.social data, examines ocean ventilation in the subpolar North Atlantic. These insights enhance our understanding of how oxygen enters the deep ocean and may aid in predicting future oxygen loss due to climate change.

Lastly, a big thanks to my coauthors - @aj-fassbender.bsky.social, @jdsharp.bsky.social, @dcarrollsci.bsky.social, Alison Gray, and Greg Johnson - to Sarah Battle for creating the schematic, our two reviewers, and everyone involved with @bgc-argo.bsky.social and @globaloceanbgc.bsky.social! 14/🧵

Our new 🌊 paper “Progressive oxygenation of the North Atlantic Subpolar Gyre” is out @jgroceans.bsky.social (open access): agupubs.onlinelibrary.wiley.com/doi/10.1029/... We examined the breathing of one of the ocean’s lungs 🩺 and found some surprises Paper summary in schematic, more info ⬇️ 1/🧵

Which is where our study comes in - improving our understanding of how the North Atlantic is ventilated currently To find out, we used GOBAI-O2, a data product created by @jdsharp.bsky.social with the help of an army of ocean robots that sample all over the world (@bgc-argo.bsky.social) 6/🧵
