Burt, Daniel J.; et al. (2021): The Sensitivity of the Marine Carbonate System to Regional Ocean Alkalinity Enhancement

Burt, Daniel J.; Fröb, Friederike; Ilyina, Tatiana (2021): The Sensitivity of the Marine Carbonate System to Regional Ocean Alkalinity Enhancement. In Front. Clim. 3, p. 21. DOI: 10.3389/fclim.2021.624075.

„Ocean Alkalinity Enhancement (OAE) simultaneously mitigates atmospheric concentrations of CO2 and ocean acidification; however, no previous studies have investigated the response of the non-linear marine carbonate system sensitivity to alkalinity enhancement on regional scales. We hypothesise that regional implementations of OAE can sequester more atmospheric CO2 than a global implementation.“

Call for Nominations: Designing a Framework for Responsible Research to Evaluate CO2 Removal and Environmental Effects of Sinking Marine Biomass: Call for Nominations to an Expert Working Group

Deadline: 22. August 2021

„Ocean Visions and its partner, the Monterey Bay Aquarium Research Institute (MBARI), announce a call for self-nominations from scientists, engineers, technologists, entrepreneurs, environmental managers, conservationists, and other relevant actors to join a working group to develop a framework for responsible research regarding the fate and environmental impacts of sinking marine biomass (seaweed) to the deep ocean for carbon dioxide removal.“

Project: CDRmare

„In order to support pathways that achieve the Paris Agreement goals, the DAM Research Mission »Marine Carbon Sinks in Decarbonization Pathways« will address as to whether and to what extent the ocean can play a substantial role in removing and storing CO2 from the atmosphere. The product will be a Marine Carbon Roadmap for a sustainable utilization of the marine carbon pools on regional to global scales.“

Siegel, David A.; et al. (2021): Assessing the sequestration time scales of some ocean-based carbon dioxide reduction strategies

Siegel, David A.; DeVries, Tim; Doney, Scott; Bell, Tom (2021): Assessing the sequestration time scales of some ocean-based carbon dioxide reduction strategies. In Environ. Res. Lett. DOI: 10.1088/1748-9326/ac0be0.

„Here, a model of steady state global ocean circulation and mixing is used to assess the time scales over which CO2 injected in the ocean interior remains sequestered from the atmosphere.“
