I'm proposing a special issue on mCDR across AGU journals. If you expect to have a suitable manuscript ready by Mar-27, please DM me the title, author list, and target AGU journal. I'm also looking for colleagues interested in serving as co-organizers—let me know if you'd like to be involved.

Happy World Ocean Day! The ocean is the heart of our life support system, without which we’d all be dead. It’s taken up >90% of the heat from global warming and 30% of our CO₂ emissions. In return, we give it 11 million tonnes of plastic annually, which animals ingest and also become entangled in.

Oceans Awash in Plastic Waste

On a day that many might be headed to the beach, take a moment to consider some of the widespread impacts of all of that plastic, and the ongoing efforts to clean it up.

Fantastic review on the ocean carbon cycle and climate led by Laure Resplandy that pulls together impressive budgets and tackles some key narratives 🌊 www.science.org/doi/pdf/10.1...

1/1 The GCP-Global Carbon Budget 2025 has just been published in its final form. It is the same data we released at the last COP in Nov 2025, but given the many improvements this budget introduced compared to previous editions, it underwent a longer and more detailed peer review process.

This week I was in Montreal for the annual AGU Publications retreat. We talked thru how we, the science community, would like AGU Journals to excel, for us, in the future! Our society journals are our journals. I never valued that more than I do now.

Starting a small series here: highlighting one JGR-Oceans paper I edited each month. Many excellent studies, but this one stood out — discovery of a dipole-like chlorophyll contrast around Sri Lanka dome (H1). @jgroceans.bsky.social @agu.org doi.org/10.1029/2025...

I’ve led over 20 expeditions to the open ocean, chasing how currents are changing as our climate warms, only to find the answer lies at the smallest, most chaotic scales. Eddies are reshaping even the mightiest currents and bringing more extremes to coastal seas. www.nature.com/articles/s41...

One of the dumbest claims from climate deniers is that ocean warming is from deep-sea volcanoes. ³He in the deep ocean comes from volcanoes, and if heat and carbon did too, the ocean temp and carbon distribution would be similar to ³He (they’re not). agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Ocean waters are aging? What? Yes: oceanographers call 'age' the time since deep ocean water was last in touch with the atmosphere. It is a measure of 'ventilation', deep vertical overturning of the ocean. Data show this process is slowing: #AMOC slowdown. Bad news. 🌊 www.geomar.de/en/news/arti...
