The oceanic physical injection pimp of organic carbon.

New paper, done with some good old friends.

Note the proposition of a horizon surtace for the carbon export that combines mixing with light penetration.

Bottom trawling is horribly destructive to coastal ocean ecosystems, and deep-sea mining will do the same to the open ocean. #OceanFilm 🌊

Principles for responsible and effective marine carbon dioxide removal development and governance - Ocean Panel Launched on June 4, 2025, at the One Ocean Science Congress in Nice, France, ahead of the United Nations Ocean Conference, this Blue Paper was

I helped draft this open letter about last Friday’s gold standard science executive order. Take a look and consider signing if you agree.

This is phenomenal.

Sea surface temperatures are >5C above average to the west of the UK and around Iceland. It's the strongest area of anomalous warmth on the planet at the moment.

It's the warmest in recorded history for northwest Europe.

NYU has been up there with Columbia for complicity. Just appalling stuff.

Conclusions from Al’s presentation: • Iron limitation will not make a significant contribution to ocean carbon dioxide removal, even if tech challenges to scalability are dealt with • ~4 years of emissions assuming the most optimal (impossible to achieve) scenario • The similarity of the 'fingerprint' of OlF on ocean biogeochemistry to climate change will make MRV very difficult • Negative impacts on fisheries will compound climate effects and may emerge after 15-20 years after initiation of OlF • Hampering our ability to reverse course or cease 🌊

@altagliabue.bsky.social making a presentation at @ucl.ac.uk telling us that ocean iron fertilization won’t do jack for climate and will further harm fisheries.

Yet, it’s the marine CO₂ removal (mCDR) method that has sold the most credits so far. 🤷🏻‍♂️

A dynamical geography of observed trends in the global ocean An empirical analysis of upper ocean physics reveals the factors that shape the seascape evolution in response to global warming.

Here a new point of view on the response of the global ocean to climate change.

In short: we cannot separate temperature from the rest when we look at trends in the dynamics.

It is just a starting point. With the great Bruno Buongiorno Nardelli.

The densest water in the world ocean forms around Antarctica, and then spreads out to flood the global abyss. We’ve seen the production of this water dwindle over the past few decades, a change that is now impacting the North Atlantic. 🌊🧪❄️

This is a highly recommendable reading. I am very much enjoying @mitpress.bsky.social Terrence Sejnowski's book, written by one of the founding fathers of computational neuroscience and AI.

How Life Really Works Just as I uncovered a new way to understand life, I got news about my own.

For those of us who are not professional biologists, it can be daunting to hear about transcription factors, signaling pathways and non-coding RNA. But this poignant piece from @philipcball.bsky.social opened my eyes to how deep and essential these ideas truly are. nautil.us/how-life-rea...

The SOCCOM & GO-BGC Christmas Tree.

Happy Holidays from the SOCCOM (soccom.princeton.edu) and GO-BGC (go-bgc.org) projects. The present under the tree? 115 BGC-Argo profiling floats deployed this year and more at sea. All data freely available.

Thanks to all the folks who made this happen and the US NSF for their support.
