Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

A Regional Intercomparison of Ice Sheet Mass Balance Estimates of the Northwest Greenland Ice Sheet
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Changes in ice sheet mass manifest as changes in ice flow, ice thickness, and gravitational attraction. These parameters can be measured from space and used to track Greenland's contribution to sea level rise independently from each other. While an excellent level of agreement between these satellite techniques has been demonstrated at the ice

Terra Nova, Volume 38, Issue 5, Page 306-313, October 2026.ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Rodingite‐Derived Melt as a Recipe for Ultra‐Calcic Magmas
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Rodingite is a high‐CaO rock formed by Ca‐rich fluid metasomatism on mafic protoliths. It typically occurs within serpentinite and represents an often‐overlooked constituent of the altered oceanic lithosphere that may be subducted into the mantle.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Low‐level atmospheric circulation over central North and South America, characterized by climatological poleward flow and strong low‐level jets (LLJs), is crucial for regional hydroclimate. These winds are known to intensify with elevated terrain.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We present new results from ambient noise tomography and azimuthal anisotropy analysis of the DOMERAPI data set to investigate crustal structure beneath the Merapi‐Merbabu‐Telomoyo region in central Java. The 3D shear‐wave velocity (Vs) model reveals a prominent high‐Vs anomaly extending from south of Merapi through Merbabu to Telomoyo ...

Hydrogen‐Dominated Iron Phase Stability and the Structure of the Earth's Inner Core
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The crystal structure of Earth's inner core (IC) remains debated, with the free energy difference between hexagonal close‐packed (hcp) and body‐centered cubic (bcc) iron under IC conditions being very small. We use ab initio and machine learning force field molecular dynamics simulations to show that hydrogen can strongly influence the phase ...

Volume changes at Santiaguito volcano between 2011 and 2019 based on TanDEM-X InSAR data
Frontiers in Earth ScienceThe Santiaguito volcanic dome complex in Guatemala consists of four volcanic domes formed within the 1902 eruption crater of Santa María volcano, with only the oldest dome, Caliente, currently active.
