Short summary
We spectroscopically evaluated the gradients of dissolved C, N, S, Fe and Mn in a newly formed redox-stratified lake. The lake features an intermediate redox state between nitrogenous and euxinic conditions that encompasses vigorous open sulfur cycling fuelled by the reducible Fe and Mn stocks of the anoxic sediments. This results in substantial bottom water loads of dissolved iron and sulfate. Observations made in this ecosystem have relevance for deep-time paleoceanographic reconstructions.
