Neutralized carbon release in the past holds lessens for the future

By publication, ,

Ryan Green led a study investigating a the natural occurrence of geologic carbon release that is neutralized by alkalinity, so that it did not cause ocean acidification or atmospheric CO2 rise. The scale of the carbon pulse may have been twice the amount of all anthropogenic fossil fuel use combined. Studying this anomaly can give us clues about the effectiveness and environmental effects of purposeful Ocean Alkalinity Enhancement in an effort to neutralize anthropogenic CO2 and slow climate change.

Ryan Green receives ARCS fellowship

Ryan Green

Ryan’s ongoing research investigates a massive pH-neutral carbon release in the Gulf of California region at the end of the last ice age with carbon cycle model simulations. For his ARCS fellowship he proposes to leverage his skills and expertise to investigate the neutralization of anthropogenic ocean acidification by purposeful release of base in the ocean, which is meant to remove CO2 from the atmosphere and mitigate climate change. Congrats Ryan!

Maddie honored with ARCS Fellowship

Madison Wood’s exciting research proposal–to reconstruct global carbon cycle perturbations using the novel stable strontium isotope proxy record measured on pelagic barite that accumulate in deep sea sediments–has been selected by the ARCS Foundation from national entries . Excellent work and well deserved. Congratulations Maddie!

Also, if you are looking for a teaser of Maddie’s work plan, listen carefully to her narrating the long-term carbon cycle …

Apply Now: PhD opportunity

I am looking to recruit a PhD student to work on seawater carbonate chemistry modeling and reconstruction of past changes in ocean acidity and atmospheric CO2. This project is aimed to improve our understanding of the role of the global carbon cycle in driving past climates. Please contact me for more details; general info on the UCSC graduate program in Earth and Planetary Sciences, and details on the application process.

The application deadline is January 3rd 2021 and the start date is Fall 2021.
