Very excited about this new paper out in Nature Geoscience titled End-Permian marine extinction due to temperature-driven nutrient recycling and euxinia! We use constraints of global redox conditions (from uranium isotopes) and the spatial variability of redox (from many different types of proxies) to compare with cGENIE results. With this data-model coupling, we argue that warmer temperatures in the Early Triassic led to higher microbial respiration rates in the ocean (i.e., a stronger biological pump), which would have resulted in high amounts of nutrient recycling in the water column, sustaining anoxic conditions and poisonous hydrogen sulfide gas! Thanks, Dom, for leading this very fun project.
