Zanna Chase's research focuses on the interaction between chemical cycles and biological activity in the oceans, and how these are affected by climate. Understanding of these interactions, both in the modern ocean and the paleo-ocean, is necessary to predict the oceans' response and contribution to future climate change. She is particularly interested in the role of iron as a key micro-nutrient to support biological productivity. Dr Chase uses a variety of geochemical proxies in sediment cores, including long-lived, naturally occurring radioisotopes to reconstruct particle flux, and redox-sensitive metals to reconstruct ocean oxygenation.
