‼️Check out our new paper led by Phil Boyd on « The need to explore the potential of marine CDR – A guide for policy makers » with Minhan Dai, Louis Legendre, Terre Satterfield and Romany Webb. Thanks are due to Peter Thomson for his suggestion to produce this policy brief. Hopefully, it will be useful for discussion at the #OneOceanScience congress and #UNOC3 in Nice, France, June 2025.

Our new paper on mapping the Ocean Alkalinity Enhancement (OAE) Efficiency across the global ocean: #mcdr #cdr #co2
We ran pulsed alkalinity simulations in 690 different locations and 4 different seasons for a total of 2760 runs.
We found strong seasonality in subtropical and polar regions. Subpolar regions equilibrate the fastest and most complete. Equatorial regions are the slowest but eventually reach near-complete equilibration after 15 years. 1/

We spent 4 years working on this paper about the scientific, legal, economic, and governance considerations of whether coastal and marine carbon dioxide removal (#mCDR) can help close the emissions gap. Please take a look and tell me if it was worth it.

« An ambitious strategy aims to cool the planet by dumping farmed seaweed on the sea floor. Will it work? »
The answer is most likely no and it would raise issues in the deep sea.

These methods are often promoted without a proper understanding of the marine carbon cycle and the processes needed for successful upscaling. This lack of knowledge threatens the validity of carbon offset initiatives. Additionally, focusing solely on CO2 removal overlooks the many non-climatic benefits of ocean-based approaches, which can exceed their CO2 capture capabilities.

SeaCure recently held a Workshop in London to discuss some important aspects of monitoring, reporting, and verification (MRV) for marine CO₂ removal (#mCDR).
But more importantly, look for me and Prof. Andy Watson FRS in these two pictures taken 30 years apart (bonus for spotting Dave Keeling of the Keeling Curve in the earlier picture).

‼️Check out our new paper “Air-sea carbon dioxide equilibrium: Will it be possible to use seaweeds for carbon removal offsets?” Here, we explain why quantifying air-sea CO2 equilibrium and linking this process to seaweed carbon storage pools is the critical step needed to verify CDR by discrete seaweed beds and nearshore and open ocean aquaculture systems prior to their use in carbon trading.

We shouldn’t use #mCDR to justify making large scale ocean observations (there are perfectly valid reasons to make these observations but they will never be used for MRV of mCDR).
Doing so will make us lose credibility with those who know, and mislead those who don’t know.
