Evolving the Geodetic Infrastructure
Enhancements to the largely invisible framework will enable researchers to investigate pressing questions about our planet’s future.
Tiny Kinks Record Ancient Quakes
As Earth ruptures, micas kink. These kink bands hide in rocks millions of years old, preserving evidence of past quakes.
Where Do the Metals Go?
Volcanic eruptions spread harmful metals in the environment. Now the biggest study to date details exactly where they end up.
Tree Rings Show Record of Newly Identified Extreme Solar Activity Event
Mass spectroscopy of tree ring material indicates a sharp, single-year rise in carbon-14 concentrations consistent with an extreme solar energetic particle event that occurred around 5410 BCE.
Subduction Initiation May Depend on a Tectonic Plate’s History
New seismic imaging study of the Puysegur Trench aims to solve one of the last major questions in plate tectonics.
Vestiges of a Volcanic Arc Hidden Within Chicxulub Crater
Scientists discovered magmatic remnants of a volcanic arc by dating granitic rocks of the middle crust excavated by, and hidden within, the Chicxulub impact crater.
Carbonate Standards Ensure Better Paleothermometers
A community effort finds that carbonate standards eliminate the interlaboratory differences plaguing carbonate clumped-isotope thermometry studies.
A Window into the Weather on Titan
Cassini’s final flybys of Saturn’s largest moon may have captured a temperature drop due to rainfall, one of the first observations of weather changes on Titan.
The First Angstrom-Scale View of Weathering
Researchers observe how water vapor and liquid alter sedimentary rocks through physical and chemical processes.
Superlasers Shed Light on Super-Earth Mantles
By compressing iron oxide to pressures expected inside a large and rocky exoplanet, scientists discovered that such mantles could layer, mix, and flow in ways very different from those inside our planet.
