Satellite Estimates for Hydroclimatic Extremes

by Jonathan H. Jiang 20 September 202128 September 2021

A new study corrects poor-performing satellite-based rainfall estimates with gauge data and also fills gauge data gaps using well-performing satellite-based rainfall estimates.

Revealing How Rock Glaciers Respond to Climate Change

by Ann Rowan 17 September 202128 July 2022

Detailed measurements of the geometry and flow of Laurichard rock glacier over 67 years reveal the distinctive behavior of these landforms through periods of warming and cooling.

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.

Himalayan Tectonics in the Driver’s Seat, Not Climate?

by Peter Zeitler 15 September 20213 May 2022

Earth’s oscillating climate is a natural guess to explain cyclic patterns in erosion, but new sediment data suggests that cyclicity may emerge from tectonic processes adding material to the Himalaya.

Bottom-up Meets Top-down Estimates of Wetland Methane Emissions

Eric Davidson, president-elect of AGU by Eric Davidson 15 September 20212 November 2021

An innovative integration of models and satellite observations indicates weak temperature sensitivity of CH4 emissions from tropical wetlands, but temperature sensitivity is high at higher latitudes.

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.

Subduction Zone Earthquakes: Fast and Slow, Weak and Strong

by T. Parsons 13 September 202118 January 2022

What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.

Atoll Seismometer Detection of Solitary Ocean Waves

by Thorsten W. Becker 10 September 202113 January 2022

Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.

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.
