Feng, Ellias Y.; et al. (2016): Could artificial ocean alkalinization protect tropical coral ecosystems from ocean acidification?

Feng, Ellias Y.; Keller, David P.; Koeve, Wolfgang; Oschlies, Andreas (2016): Could artificial ocean alkalinization protect tropical coral ecosystems from ocean acidification? In Environ. Res. Lett. 11 (7), p. 74008–74008. DOI 10.1088/1748-9326/11/7/074008.

"Artificial ocean alkalinization (AOA) is investigated as a method to mitigate local ocean acidification and protect tropical coral ecosystems during a 21st century high CO2 emission scenario. Employing an Earth system model of intermediate complexity, our implementation of AOA in the Great Barrier Reef, Caribbean Sea and South China Sea regions, shows that alkalinization has the potential to counteract expected 21st century local acidification in regard to both oceanic surface aragonite saturation Ω and surface pCO2."

González, Miriam Ferrer; Ilyina, Tatiana (2016): Impacts of artificial ocean alkalinization on the carbon cycle and climate in Earth system simulations

González, Miriam Ferrer; Ilyina, Tatiana (2016): Impacts of artificial ocean alkalinization on the carbon cycle and climate in Earth system simulations. In Geophys. Res. Lett. DOI 10.1002/2016GL068576.

"Using the state-of-the-art emissions-driven Max-Planck-Institute Earth system model, we explore the impacts of artificial ocean alkalinization (AOA) with a scenario based on the Representative Concentration Pathway (RCP) framework. Addition of 114 Pmol of alkalinity to the surface ocean stabilizes atmospheric CO2 concentration to RCP4.5 levels under RCP8.5 emissions."

Ilyina, Tatiana (2015): The Combined Effects of Changes in Ocean Chemistry, Biology, and Hydrodynamics on Alkalinity

Ilyina, Tatiana (2015): The Combined Effects of Changes in Ocean Chemistry, Biology, and Hydrodynamics on Alkalinity. In Nova Acta Leopoldina 121 (408), pp. 107–110.

"Therefore, understanding the spatiotemporal distribution of TA changes is critical to grasp the oceanic capacity to uptake and store carbon. Furthermore, dissolution of CO2 in seawater does not change TA, but may affect processes controlling its cycling. Hence, it is also interesting to study TA in the context of climate change, i. e. in a rising CO2 ocean."

Ferrer-Gonzalez, Miriam; Ilyina, Tatiana (2015): Mitigation Potential, Risks, and Side-Effects of Ocean Alkalinity Enhancement

Ferrer-Gonzalez, Miriam; Ilyina, Tatiana (2015): Mitigation Potential, Risks, and Side-Effects of Ocean Alkalinity Enhancement. In Nova Acta Leopoldina 121 (408), pp. 275–278.

"The novelty of our research relies on the fact that none of previous studies have addressed this topic with a fully coupled Earth system model of such a level of complexity. Fully coupled set-ups (versus box-models or forced subsystems) hold the potential of revealing new features within the Earth system dynamics."
