Marine oxygen production and open water supported an active nitrogen cycle during the Marinoan Snowball Earth
Abstract
Snowball Earth glaciations were some of the most extreme climate events in Earth history, and are temporally linked to major biogeochemical changes. Here, using geochemical proxies, the authors show that during the Marinoan glaciation, there was likely open water, active oxygen production, and nitrogen cycling.
