Our last speaker this spring semester is Dr. Dalton S. Hardisty from the Earth and Environmental Science Department at Michigan State University, 
and he will be talking about: "Iodine cycling in modern and ancient marine oxygen minimum zones".
Briefly: Iodine is a redox-sensitive element and its abundance in sedimentary rocks is used as a paleoredox proxy, but constraints on the rates and mechanisms of iodine cycling in modern marine settings remain limiting.
Dr. Dalton Hardisty’s investigates how ocean chemistry and biology co-evolved throughout Earth history. This includes a major focus on constraining the initial accumulation and proliferation of oxygen in our atmosphere and oceans.
