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.

Bruno Buongiorno Nardelli @bbuong.bsky.social · Aug 3

Our data-driven analysis quantifies the organic carbon export driven by upper-ocean mixing and 3D advection. Vertical diffusion and intertwined biological production and mixing dominate net export. Interannual-variability is linked to water-mass formation dynamics.

The oceanic physical injection pump of organic carbon - Nature Communications

Ocean mixing and advection play a key role in exporting organic carbon to the deep ocean, with year-to-year variations strongly influenced by El Niño and Southern Ocean dynamics

Amazing animation of tankers burning oil to move oil

🗺️ I've spent a lot of time the past week looking at data in the Strait of Hormuz so here is a quick animation showcasing the sheer volume of activity in the Persian Gulf last Friday. The data highlights "Tanker" only vessels (AIS code 80-89) so everything from Crude Oil Tankers to LNG Tankers.

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.

Nathan Kalman-Lamb @nkalamb.bsky.social · May 15

A principled student said in a grad speech that the “only appropriate thing to say in this moment” is to acknowledge the “atrocities” currently being committed in Palestine.

In response, NYU is withholding their diploma + apologizing to the community for the trauma the audience was “subjected to.”

NYU strongly denounces the choice by a student at the Gallatin School’s graduation today—one of over 20 school graduation ceremonies across our campus—to misuse his role as student speaker to express his personal and one-sided political views.
“He lied about the speech he was going to deliver and violated the commitment he made to comply with our rules. The University is withholding his diploma while we pursue disciplinary actions.
“NYU is deeply sorry that the audience was subjected to these remarks and that this moment was stolen by someone who abused a privilege that was conferred upon him.”

@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. 🤷🏻‍♂️

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 🌊

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.
