This @davidho.bsky.social post comes to mind whenever I read, hear, or even write about the BlueEconomy or mCDR.

Why can't we address environmental challenges from a non-capitalist perspective?

Is it even possible to solve societal issues within the same system that generated them?

Why is there the expectation that f**king up the planet and saving it should both be profitable?

Last week, I had the opportunity to attend an inspiring talk by Ariane Koek, a renowned curator of ArtScience.

I recommend reading her words to glimpse the relevance of art-science collaborations and the need to support and generate Science beyond technological applications.

One tweet contains no nuance, so I'll post this great summary from a year ago by David Wallace-Wells, for those who want nuance on the causes of fires and the role of climate change vis-a-vis other factors
Fires Are the Sum of Our Choices (Gift Article)
Climate change, ecology and fire suppression have combined to bring us the return of the “urban firestorm.”

The problem with a lot of ocean "exploitation" is that it's like mining a human for calcium. Yes, a human body contains ~1kg of calcium, and you could take it out, but it's already *doing* quite a lot of useful things, and the human has far more potential to help you if you leave the calcium alone.

Having studied ocean (iron) fertilization quite intensely for a while I think that the available science does not support its implementation. While it may sequester C (few 100 yrs) in very specific regions, it is close to impossible to verify. 🌊

Thanks for this great summary @jhauck.bsky.social and all the work behind!

Do we know why observations decreased so much? Less observational programs? Less ship time? I wonder if anybody has looked into the reasons of this worrying decline...

😅 oups...sorry about this! And thank you!

Excited to be heading to Goa (India) for a new edition of the SOLAS Open Science Conference #SOLAS_OSC2024.

A week ahead full of great science and community building in the air-sea domain.

Some events, like the one below, can be followed online! 👇

Great!
Can I join the community?

Interested in ocean chlorophyll? A new paper by Long et al. rdcu.be/dXcjY explores the relationship between chloro, measured by BGC-Argo floats and by ocean color satellites. The figure shows seasonal maps of Chl_flt/Chl_sat. Systematic variations in the ratio are likely due to effects of Fe.

This is a story about deep sea mining, beautifully told.

Mining something that takes millions of years to form. What could go wrong? Ehm…🛢️👀

Letting an industry with a terrible record on land do the same in the ocean where there’s way less oversight. What could go wrong? 🤔
The promise and risks of deep-sea mining
A vast treasure of critical minerals lies on the ocean floor. Should they be extracted to help fight climate change?

Tonnes of aerosols fall over the oceans every year, and we still have no method to quantify it with confidence. Very happy to see this review out, in which we provide a comprehensive vision of current and near-future venues for evaluating aerosol deposition over the ocean.

Preformed nutrients are indeed the widely underappreciated but absolutely central metric for marine biology-mediated CO2 removal such as ocean iron fertilization, ocean afforestation or artificial upwelling.

🧵 thread where I add papers that may be important in this context

People who want to manipulate ocean biology for CO₂ removal (CDR) need to learn about preformed nutrients.
