Study led by Dalton Hardisty published in Earth Planet. Sci. Lett. showing surprisingly slow rates of iodate reduction in the Eastern Tropical North Pacific, implying that water mass mixing is an important control on the relationship between dissolved oxygen and iodine speciation in oxygen-minimum zones.
