Coupled vanadium and thallium isotope constraints on Mesoproterozoic ocean oxygenation around 1.38-1.39 Ga
The oxygenation state of the Mid-Proterozoic (1.8–0.8 Ga) ocean and atmosphere is heavily
debated and has implications for the relationship between environmental O 2 and the …

Widespread seafloor anoxia during generation of the Ediacaran Shuram carbon isotope excursion
Reconstructing the oxygenation history of Earth's oceans during the Ediacaran period (635
to 539 million years ago) has been challenging, and this has led to a polarizing debate …

Cu and Zn isotopic evidence for the magnitude of organic burial in the Mesoproterozoic Ocean
Y Lü, SA Liu - Journal of Earth Science, 2022 - Springer
The rate of net primary production in the Proterozoic ocean was suggested to be no more
