The effect of carbonate mineral additions on biogeochemical conditions in surface sediments and benthic–pelagic exchange fluxes [PDF]

Biogeosciences
Coastal sediments are hotspots of biogeochemical processes that are impacting subsurface and overlying water conditions. Fluid composition in sediments is altered through the mineralization of organic matter which, under oxic conditions, further lowers ...

Simulated Earth system response to acid downwelling as a form of ocean alkalinity enhancement

Environmental Research Letters
‘Acid downwelling’ (AD) is a proposed marine carbon dioxide removal (CDR) method, which describes the idea of electrochemically splitting open ocean surface water into an alkaline solution to remain at the surface ocean and cause additional ocean CO _2 ...

An assessment of ocean alkalinity enhancement using aqueous hydroxides: kinetics, efficiency, and precipitation thresholds [PDF]

Biogeosciences
Ocean alkalinity enhancement (OAE) is a promising approach to marine carbon dioxide removal (mCDR) that leverages the large surface area and carbon storage capacity of the oceans to sequester atmospheric CO2 as dissolved bicarbonate (HCO3-).

Mechanisms of air–sea CO₂ exchange in the central Baltic Sea [PDF]

Atmospheric Chemistry and Physics
Air–sea gas exchange regulates the cycling of climate-relevant gases such as carbon dioxide (CO2), yet significant uncertainties remain in its quantification. The gas transfer velocity (K), a key parameter for estimating CO2 flux, is usually expressed as

Novel field trial for ocean alkalinity enhancement using electrochemically derived aqueous alkalinity

Frontiers in Environmental Engineering
Ocean alkalinity enhancement is a proposed method of marine carbon dioxide removal that enhances the ocean’s uptake of atmospheric carbon dioxide (CO2) and converts it to dissolved bicarbonate for long-term ocean storage.

A system-based analysis of carbon fluxes shows that bivalve aquaculture cannot be considered a marine carbon dioxide removal strategy

Marine carbon dioxide removal (mCDR) is gaining momentum as part of the global climate mitigation portfolio. Yet as enthusiasm grows, so does the risk of overstating the carbon removal potential of marine activities that were never designed as climate ...
