The Arctic is experiencing some of the most rapid and dramatic environmental changes on Earth due to human-caused carbon dioxide emissions. These changes, including the reduction of sea ice, glacier retreat, and shifts in ocean circulation, are fundamentally reshaping Arctic marine carbon and nutrient cycles.
Iron (Fe) plays a crucial role in these processes as a bio-limiting nutrient, a terminal electron acceptor for respiration, and a key player in other biogeochemical cycles. Understanding Fe cycling in these sensitive Arctic environments is essential for predicting ecosystem responses to ongoing climate change.
In this seminar, Dr. Allyson Tessin will explore insights from modern benthic studies and paleo-oceanographic reconstructions to highlight Fe cycling in the modern Arctic and during past climate perturbations.
