Our planet’s lithosphere is broken into several tectonic plates. Their configuration is ever-shifting, as supercontinents are assembled and broken up, and oceans form, grow, and then start to close in what is known as the Wilson cycle.

In a study published in the journal Environmental Science & Technology, WashU researchers discovered that a common mineral called goethite — an iron-rich mineral that is abundant in soils that cover the Earth — tends to incorporate trace metals into its structure over time, binding the metals in such a way that it locks them out of circulation.

Researchers at the Statewide California Earthquake Center, or SCEC, are unraveling the mysteries of earthquakes by using physics-based computational models running on high-performance computing systems at the Department of Energy’s Oak Ridge National Laboratory. The team’s findings will provide a better understanding of seismic hazards in the Golden State.

Earth is a stressed planet. As plates move, magma rises, and glaciers melt—just to mention a few scenarios—rocks are subject to varying pressure and compressional and extensional forces.

Connor Bleisch, a graduate research assistant in the College of Science at The University of Alabama in Huntsville (UAH), has won the 2023 American Geophysical Union (AGU) Michael H. Freilich Data Visualization Competition grand prize. The honoree is being recognized for a data visualization project that places the user in the middle of a first-hand recreation of a raging wildfire in the Sequoia National Park in 2021.

As part of the Ice Memory initiative, researchers analysed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais. A comparison of the two sets of ice cores published in Nature Geoscience shows: Global warming has made at least this glacier unusable as a climate archive.
