The Role of Iron in The Degradation of Dissolved Organic Carbon in the Arctic by Dr. Rose Cory, Department of Earth and Environmental Sciences, University of Michigan

Abstract: Current estimates are that 5–15% of the tremendous pool of organic carbon stored in permafrost soils could be emitted as greenhouse gases by 2100 given the current trajectory of climate change, resulting in an additional one third degree Celsius of warming everywhere on Earth (i.e., Arctic amplification of climate change). However, the degree to which climate change will be amplified by greenhouse gases released from thawing permafrost is highly uncertain in large part due to insufficient understanding of the processes that degrade dissolved organic carbon (DOC) to carbon dioxide (CO2). Our work has shown that DOC degradation is tightly coupled to iron redox cycling in permafrost soils of the Arctic and in the surface waters draining these soils. For example, in waterlogged soils, redox reactions of iron produce reactive oxygen species (e.g., the hydroxyl radical) that oxidize DOC. On a landscape scale, the hydroxyl radical produced by iron redox cycling can oxidize as much DOC to CO2 as does microbial respiration of DOC in arctic surface waters. Upon export of dissolved iron and DOC from permafrost soils to sunlit surface waters, iron likely catalyzes the sunlight-driven (photochemical) oxidation of DOC to CO2. As a consequence, current estimates of additional global warming from the permafrost carbon feedback may be too low by ~ 14%.

Master\'s Thesis Presentations

April, 19 2024

Time: 2:00 PM - 5:00 PM
Location: JGB

The Master of Science (MS) degree at the Jackson School of Geosciences is considered to be the professional degree for a career in the Geosciences. This degree is the foundation for students pursuing employment in the petroleum industry, environmental and hydrogeological fields, state and federal government agencies, and other related geoscience fields. Some students also use the MS degree as preparation for pursuing a Ph.D.

The Energy & Earth Resources Interdisciplinary program provides the opportunity for students to prepare themselves in management, finance, economics, law and policy leading to analytical and leadership positions in resource-related fields. The private sector and government organizations face a growing need for professionals that can plan, evaluate, and manage complex resource projects, commonly international in scope, which often include partners with a variety of professional backgrounds.

As requirements for these degrees, students must present a professional talk on Master\'s Thesis Presentations.
