Geochemistry, Geophysics, Geosystems is a gold open access journal that publishes original research papers on Earth and planetary processes with a focus on understanding the Earth as a system.
The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic slabs, is stored in minerals ...

Melting ice sheets are often considered synonymous with climate change in the media, with evocative images of lone polar bears floating on ever-shrinking rafts of ice. While impacts such as sea level rise and salinity changes ...
A slow climate feedback loop may be bubbling beneath Antarctica's vast ice sheet. The continent, divided east to west by the Transantarctic Mountains, includes volcanic giants such as Mount Erebus and its iconic lava lake. ...
