The Arctic is experiencing some of the fastest and most dramatic changes on Earth in response to human-caused carbon dioxide emissions, including rapid reduction of sea ice, retreat of glaciers, and changing ocean circulation patterns. These changes are fundamentally re-organizing Arctic marine carbon and nutrient cycles. Iron (Fe) cycling within these sensitive Arctic environments is important because Fe plays a key role as a bio-limiting nutrient, a terminal electron acceptor for respiration, and it can control other biogeochemical cycling. Modern benthic studies and paleo-oceanographic reconstructions provide key information about Fe cycling in the modern and during past climate perturbations.
