Zanna Chase is an ocean-going professor of chemical oceanography and paleoceanography at the Institute of Marine and Antarctic Science, University of Tasmania, Australia.
[1] She then completed her Master's degree in biological oceanography at McGill University in 1996 working on how iron controls marine protozoans.
[2] She undertook her PhD in chemical oceanography and paleoceanography at Lamont–Doherty Earth Observatory where she worked on trace elements and primary production in marine ecosystems.
[6] She uses a range of geochemical proxies analysed on ocean waters and sediment cores including long-lived, naturally occurring radioisotopes like thorium isotopes to reconstruct particle flux, and redox-sensitive metals such as manganese and uranium to reconstruct ocean oxygen levels.
She is also involved in research to improve the understanding of trace metal proxies through participation in the international Geotraces program.
