Tyka, Michael; et al. (2021): CO2 capture by pumping surface acidity to the deep ocean

Tyka, Michael; Platt, John; van Arsdale, Christopher (2021): CO2 capture by pumping surface acidity to the deep ocean. Preprint. DOI: 10.31223/X5TK60.

"Here we present a method which relies purely on the redistribution and dilution of acidity from a thin layer of the surface ocean to a thicker layer of deep ocean, with the aim of reducing surface acidification and accelerating the former carbonate homeostasis."

Terhaar, Jens, et al. (2021): Southern Ocean anthropogenic carbon sink constrained by sea surface salinity

Terhaar, Jens; Frölicher, Thomas L.; Joos, Fortunat (2021): Southern Ocean anthropogenic carbon sink constrained by sea surface salinity. In Science Advances 7 (18). DOI: 10.1126/sciadv.abd5964.

"We identify a tight relationship across two multimodel ensembles between present-day sea surface salinity in the subtropical-polar frontal zone and the anthropogenic carbon sink in the Southern Ocean."

EurekAlert!: Uncertainty of future Southern Ocean CO2 uptake cut in half

"Together with Thomas Frölicher and Fortunat Joos, who are also researchers at the Oeschger Centre, Terhaar has just presented in the scientific journal "Sciences Advances" a new method for constraining the Southern Ocean's CO2 sink."

Condie, Scott A.; et al. (2021): Large-scale interventions may delay decline of the Great Barrier Reef

Condie, Scott A.; Anthony, Kenneth R. N.; Babcock, Russ C.; Baird, Mark E.; Beeden, Roger; Fletcher, Cameron S. et al. (2021): Large-scale interventions may delay decline of the Great Barrier Reef. In R. Soc. open sci. 8 (4). DOI: 10.1098/rsos.201296.

"Evaluating the efficacy of alternative interventions in a complex system experiencing major cumulative impacts can only be achieved through a systems modelling approach. We have evaluated combinations of interventions using a coral reef meta-community model."

Butenschön, Momme; et al. (2021): Alkalinization Scenarios in the Mediterranean Sea for Efficient Removal of Atmospheric CO2 and the Mitigation of Ocean Acidification

Butenschön, Momme; Lovato, Tomas; Masina, Simona; Caserini, Stefano; Grosso, Mario (2021): Alkalinization Scenarios in the Mediterranean Sea for Efficient Removal of Atmospheric CO2 and the Mitigation of Ocean Acidification. In Front. Clim. 3, p. 14. DOI: 10.3389/fclim.2021.614537.

"This study investigates the case of ocean alkalinization, which has the additional potential of contrasting the ongoing acidification resulting from increased uptake of atmospheric CO2 by the seas. More specifically, we present an analysis of marine alkalinization applied to the Mediterranean Sea taking into consideration the regional characteristics of the basin."

Our Shared Seas: A Primer for Philanthropy on Ocean-Climate Interventions

"One useful categorization of ocean-climate efforts divides interventions into three areas: the mitigation of future greenhouse gas emissions, the accelerated sequestration of atmospheric CO2, and adaptation efforts to help vulnerable habitats and communities adapt to the stresses of climate change."

Phys.org: Could kelp help relieve ocean acidification?

"Ethereal, swaying pillars of brown kelp along California's coasts grow up through the water column, culminating in a dense surface canopy of thick fronds that provide homes and refuge for numerous marine creatures. There's speculation that these giant algae may protect coastal ecosystems by helping alleviate acidification caused by too much atmospheric carbon being absorbed by the seas."

World Resources Institute: Leveraging the Ocean's Carbon Removal Potential

"As the need for climate action becomes more urgent, the ocean is gaining attention as a potential part of the solution. Approaches like investing in offshore energy production, conserving coastal ecosystems and increasing consumption of sustainable ocean-based protein offer opportunities to reduce emissions. In addition to these opportunities, a range of ocean-based carbon removal approaches could help capture and store billion of tons of carbon."
