Alkalinity enhancement with sodium hydroxide in coastal ocean waters [PDF]

Scientific Reports
Carbon Dioxide Removal (CDR) is increasingly recognised as essential for achieving net zero emissions to limit the impacts of climate change. Ocean Alkalinity Enhancement (OAE) presents a potentially scalable marine CDR (mCDR) technique.

Laying waste to the deep: parallel narratives of marine carbon dioxide removal and deep-seabed mining

npj Ocean Sustainability
The deep ocean is increasingly featured in climate solution discussions. An emerging narrative suggests that marine carbon dioxide removal (mCDR) is essential to meet global climate targets. The argument made is similar to claims that deep-seabed mining (

The State of the Science for Marine Carbon Dioxide Removal (mCDR) – A Scientific Summary for Policy-Makers

Since net zero greenhouse gas emissions targets have become a keystone of climate policy, there has been increasing debate about the need to complement urgently needed emission reductions with active removal of carbon dioxide from the atmosphere (termed ‘carbon dioxide removal’, CDR)This document provides a concise summary of the state of marine CDR ...

On the Efficiency and Durability of Purposefully Sinking Seaweed Biomass as a Marine Carbon Dioxide Removal Strategy

Earth's Future
Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of

Removal of dissolved inorganic carbon from seawater for climate mitigation: potential marine ecosystem impacts

Frontiers in Climate
Electrochemical technology can be used to remove inorganic carbon from seawater and facilitate the removal of carbon dioxide (CO2) from the atmosphere. Electrochemical ‘Direct Ocean Carbon Capture and Storage’ (DOCCS) is a marine carbon dioxide removal ...

Biological response of eelgrass epifauna, Taylor's Sea hare (Phyllaplysia taylori) and eelgrass isopod (Idotea resecata), to elevated ocean alkalinity [PDF]

Biogeosciences
Marine carbon dioxide removal (mCDR) approaches are under development to mitigate the effects of climate change by sequestering carbon in stable reservoirs, with the potential co-benefit of local reductions in coastal acidification impacts.

Ocean alkalinity enhancement impacts: regrowth of marine microalgae in alkaline mineral concentrations simulating the initial concentrations after ship-based dispersions [PDF]

Biogeosciences
Increasing the marine carbon dioxide (CO2) absorption capacity by adding alkaline minerals into the world's oceans is a promising marine carbon dioxide removal (mCDR) approach to increase the ocean's CO2 storage potential and mitigate ocean acidification.
