🌊 In 2023, the ocean carbon sink weakened for the first time in a record-hot year 🌡️🌎 Our new study in Nature Climate Change quantifies this unexpected decline and explains how it came about. 👇 doi.org/10.1038/s415...

Meltwater strongly perturbs the carbonate system in the ocean. Henson et al., use new data from Greenland to show that, as well as driving an inorganic CO2 sink, the diluting influence of meltwater on alkalinity weakens the buffering capacity of these regions 🌊 www.nature.com/articles/s43...

The #DINEOF pictures that are shown daily at www.dineof.uliege.be adjust the colors to maximise contrast using the temperature interval of the last 10 days. Seems it can't keep up with the warming trend these days, it's just saturated over large areas (28°C!). You can look at the last 10days there 🌊

It includes an epic sentence: "The carbonate chemistry of seawater is painfully full of surprises." Agree.😅

We were this week in Pontevedra showing our cost-effective oceanographic solution #BOGAR! A @unoceandecade.bsky.social endorsed project for underway observing surface waters. What an amazing week at @sibecol-aeet-25.bsky.social!

After 19 consecutive days, time to say goodbye 👋🏻 to these fellows. #OAEPIIP Never in my life I took so care about a tiny volume of seawater. 😅

A week ago, our contribution to the #OAEPIIP intercomparison project set sail!⛵ This globally coordinated effort investigate the potential effects of ocean alkalinity enhancement (OAE, a #mCDR technique) on plankton communities. Huge thanks to the entire team making it possible!

A new article lists 4 priorities for improving the AMOC in climate models: (1) defining a set of standard metrics; (2) developing a framework for budget analyses; (3) improving the Nordic Seas overflow; & (4) improving the impact of ice sheet melt on the AMOC: 🌊🧪 journals.ametsoc.org/view/journal...

Adding alkalinity to the ocean might enable it to take up more atmospheric CO₂, but much more research in laboratories, mesocosms, and field studies is needed before considering full-scale deployment. I have some thoughts in this piece. 🌊
