| Nature Verified
Abstract Contemporary observations indicate that dissolved oxygen concentrations are generally declining as global temperatures rise, which has broad implications for carbon cycling and the habitable ranges of marine animals.

A reversed latitudinal ocean oxygen gradient in the Proterozoic Eon - Nature Geoscience

|
By Alexandre Pohl, Xingliang Zhang, Chao Chang, Jonathan Payne, Shuhai Xiao, Andy Ridgwell, Ruliang He
| Nature Verified
Abstract Major changes in the oxygenation of the atmosphere and ocean have been suggested to trigger the taxonomic diversification and ecological expansion of complex life, including animals, during the Neoproterozoic–Palaeozoic transition. However, testing this hypothesis is hampered by the paucity of quantitative constraints on the oceanic oxygen availability at that time.
