Kirsi Keskitalo

Kirsi Keskitalo is a researcher affiliated with Northumbria University, contributing to interdisciplinary environmental and earth sciences research. Her work focuses on permafrost degradation, carbon dynamics in Arctic and Siberian environments, and the biogeochemical interactions between terrestrial, fluvial, and marine systems.

Research interests include particulate organic carbon transport in rivers like the Kolyma, organic matter preservation mechanisms, and greenhouse gas emissions from thawing Yedoma permafrost sites. She has conducted fieldwork in Siberia and the Canadian Arctic, investigating retrogressive thaw slumps and their impacts on carbon cycling.

Publications highlight studies on Laptev and East Siberian Shelf sediments, seasonal river dynamics, and iron interactions preserving organic carbon. Her work bridges fluvial, marine, and terrestrial systems to understand climate feedbacks in permafrost regions.
