Allyson Tessin

Allyson Tessin is an Assistant Professor in the Department of Earth Sciences at Kent State University, leading the Sediment Biogeochemistry Lab. Her research focuses on marine carbon cycle dynamics and climate change, particularly investigating ocean deoxygenation, land-to-sea carbon fluxes, and benthic-pelagic coupling. She employs interdisciplinary methods combining seagoing research, geological fieldwork, and geochemical analyses to study modern and ancient marine systems.

Education: Ph.D. and M.S. from the University of Michigan, B.Phil. and B.A. from the University of Pittsburgh.

Research Interests: Tessin bridges oceanography, biogeochemistry, and sedimentary geology. Key areas include Arctic marine sediment processes, Cretaceous climate studies, and the role of iron/manganese in organic carbon preservation. Her work integrates international collaborations, such as the IODP Expedition 392.

Publications highlight contributions to understanding Arctic benthic silicon cycles, organic matter transformation, and paleoenvironmental reconstructions. Her lab emphasizes fieldwork in Arctic regions and geological formations like the Western Interior Seaway.

Grants and Future Work: Her projects explore ice sheet instability impacts on Arctic carbon cycles and involve advanced geochemical techniques. The lab actively participates in scientific ocean drilling initiatives and environmental monitoring of Arctic margins.

Labs/Teams: Sediment Biogeochemistry Lab at Kent State collaborates globally on marine geochemical studies, emphasizing Arctic and Cretaceous-era systems.
