The impact of NaOH, CaO, and [Ca 2+ ] + [HCO 3 − ] additions on PIC and POC formation in Los Angeles Harbor Waters

Rucha P. Wani, Devan L. Roper, Ria Agrawal, Esther J. Lim et autres

Negative CO 2 emission technologies such as ocean alkalinity enhancement, in tandem with emissions reduction are necessary to keep the climate system below a critical tipping point. While the biogeochemical consequences of alkalinity enhancement remain poorly constrained, field deployment is accelerating in …

Carbon Fate, Iron Dissolution, and Molecular Characterization of Dissolved Organic Matter in Thawed Yedoma Permafrost under Varying Redox Conditions

Matheus Sampaio Carneiro Barreto, Rucha P. Wani, Aleksandar I. Goranov, Tyler D. Sowers et autres

Permafrost soils store ∼50% of terrestrial C, with Yedoma permafrost containing ∼25% of the total C. Permafrost is undergoing degradation due to thawing, with potentially hazardous effects on landscape stability and water resources. Complicating ongoing efforts to project the ultimate fate of …

Spatially Resolved Organomineral Interactions across a Permafrost Chronosequence

Tyler D. Sowers, Rucha P. Wani, Elizabeth K. Coward, Matthew Fischel et autres

Permafrost contains a large (1700 Pg C) terrestrial pool of organic matter (OM) that is susceptible to degradation as global temperatures increase. Of particular importance is syngenetic Yedoma permafrost containing high OM content. Reactive iron phases promote stabilizing interactions between OM and …
