Eruptive activity of the Santorini Volcano controlled by sea-level rise and fall

Nature Geoscience, Published online: 02 August 2021; doi:10.1038/s41561-021-00783-4Sea-level lowstands over the last 360,000 years strongly controlled the timing of eruptions of the Santorini Volcano, according to an analysis of tephras and sea-level records, as well as numerical modelling of the underlying magma chamber.

Transient ocean oxygenation at end-Permian mass extinction onset shown by thallium isotopes

Nature Geoscience, Published online: 02 August 2021; doi:10.1038/s41561-021-00802-4Marine oxygenation declined well before the end-Permian mass extinction, the start of which was marked by a brief return to more oxygenated conditions, according to the analysis of thallium isotopes from sites spread across the Panthalassa ocean basin.

Possible link between Earth’s rotation rate and oxygenation

Nature Geoscience, Published online: 02 August 2021; doi:10.1038/s41561-021-00784-3Rotational deceleration has increased daylength on Earth, potentially linking the increased burial of organic carbon by cyanobacterial mats and planetary oxygenation, according to experiments and modelling of Precambrian benthic ecosystems.
