A partially molten mantle

Nature Geoscience, Published online: 06 February 2023; doi:10.1038/s41561-022-01120-zA global analysis of seismic waves has identified a widespread sharp velocity anomaly at the base of the low seismic velocity zone that is consistent with partial melting, closing a decades-long debate about the origin of this zone.

Asthenospheric low-velocity zone consistent with globally prevalent partial melting

Nature Geoscience, Published online: 06 February 2023; doi:10.1038/s41561-022-01116-9A partially molten low-seismic-velocity zone in the asthenosphere is globally prevalent, but partial melting is not the primary control of low asthenospheric viscosity, according to analysis of seismic waves travelling through the mantle.

Increased night-time oxidation over China despite widespread decrease across the globe

Nature Geoscience, Published online: 26 January 2023; doi:10.1038/s41561-022-01122-xMeasurements show that night-time production of atmospheric nitrate radicals increased in China but decreased in the European Union and the United States from 2014 to 2019. This suggests the increasing contribution of night-time atmospheric oxidation in China to air...

Rotation of the Earth’s inner core changes over decades and has come to near-halt

Nature Geoscience, Published online: 23 January 2023; doi:10.1038/s41561-022-01113-ySeismic observations reveal that the Earth’s inner core oscillates with a period of approximately seven decades. The multidecadal periodicity coincides with that of several other geophysical observations, particularly the variations in the length of day and the Earth’s...
