Long-Term Sea Level Cycle Affects Predictions of Future Rise

Sarah Stanley, Science Writer by Sarah Stanley 27 September 202126 October 2021

New research confirms the existence of a regular, long-term fluctuation in sea level, perhaps caused by processes in Earth’s core.

A Novel Thermobarometer to Infer Mantle Melting Conditions

by Susanne Straub 16 September 20214 August 2023

The algorithm RevPET automatically reverses the complex multi-phase fractional crystallization path of oceanic basalts and offers new perspectives for advancing mantle thermobarometry.

Coupled Mechanisms of Fluid Transport Across the Crust

by Beatriz Quintal 14 September 202111 May 2022

Magmatic fluid moves up in the ductile zone through porosity waves, accumulates in high-porosity lenses, and migrates across the brittle zone in a convection pattern involving also meteoric fluid.

New Inversion Method Improves Earthquake Source Imaging

by Cécile Lasserre 30 August 20218 December 2022

A new method uses Bayesian inference to jointly invert for non-planar fault geometry and spatially variable slip (with associated uncertainties) in earthquake source modeling, based on geodetic data.

Reconstructing Rocks with Machine Learning

by D. O'Malley 12 July 20213 October 2022

Machine learning can be used to accurately reconstruct high-resolution, 3D images of rocks from 2D cross-sections, which opens the door to more detailed simulations.
