Photooxidation removes biologically recalcitrant dissolved organic carbon released by the macroalga Sargassum natans

Limnology and Oceanography Letters, Volume 10, Issue 3, Page 349-359, June 2025.
Abstract Macroalgae are important primary producers in the coastal ocean, and they release a large fraction of their net primary production as dissolved organic carbon (DOC). It is assumed that much of this DOC is recalcitrant and results in the sequestration of large amounts of carbon.

Ocean alkalinity enhancement in a coastal channel: simulating localised dispersion, carbon sequestration and ecosystem impact

Environmental Research Communications
Ocean Alkalinity Enhancement (OAE) is a proposed marine carbon dioxide removal (mCDR) method that has the potential to sequester CO _2 at the gigaton scale.

Seeking natural analogs to fast-forward the assessment of marine CO2 removal

, 2021
Mitigating global climate change will require gigaton-scale carbon dioxide removal (CDR) as a supplement to rapid emissions reduction. The oceans cover 71% of the Earth surface and have the potential to provide much of the required CDR.

Accounting and monitoring challenges for blue carbon enhancement in national climate policy targets and international carbon markets

Carbon Management
“Blue carbon” refers to carbon sequestration in marine ecosystems. While carbon uptake in coastal vegetated areas has been well-studied, emerging techniques to enhance carbon uptake in open ocean environments pose new challenges in terms of accounting ...

A novel methodology to characterize the potential impacts of electrochemical ocean alkalinity enhancement on juvenile coho salmon (Oncorhynchus kisutch)

Frontiers in Climate
Ocean alkalinity enhancement (OAE) includes a branch of marine carbon dioxide removal (mCDR) methods that add alkalinity to the surface ocean, leveraging the ocean's vast natural ability to capture and store atmospheric CO2.

The need to explore the potential of marine CDR with a one-earth strategy: A guide for policy-makers

Rapid, deep and sustained reductions in carbon dioxide (CO₂) emissions are essential to achieve the goals of the Paris Climate Agreement of keeping the long-term global average surface temperature increase well below 2°C above pre-industrial levels and ...

Prospective site-specific life cycle assessment of ocean alkalinity enhancement

Environmental Research Letters
Ocean alkalinity enhancement (OAE) is a promising marine carbon dioxide removal (CDR) option, but its net climate benefit and wider environmental implications depend strongly on where, and how it is implemented as well as on decarbonized energy and ...
