Several studies suggest that large earthquakes (M > 7.0) can act as external triggers of volcanic unrest, and even eruption. This triggering is attributed to either ground shaking (dynamic stresses) or to permanent ground deformation (associated with static stress changes). However, large earthquakes are rare and testing triggering hypotheses has proven difficult. We use geodetic data to show that

Evidence for and Against Temperate Ice in Antarctic Shear Margins From Radar-Depth Sounding Data Geophys. Res. Lett. (IF 5.2) Pub Date : 2024-05-04 P. T. Summers, D. M. Schroeder, D. F. May, J. Suckale
The majority of ice mass loss from Antarctica flows through narrow, fast sliding regions of ice. The lateral boundaries of these regions, termed shear margins, are characterized by lateral shear strains in excess of ∼10−3 yr−1. Shear heating within these margins could warm ice significantly–even to the melting point–but other processes such as lateral advection of cold ice and fabric development compete

Isotopic Evidence for Degradation of Particulate Black Carbon in the Ocean Geophys. Res. Lett. (IF 5.2) Pub Date : 2024-05-04 Siddhartha Sarkar, Abdur Rahman, Mohammad Atif Khan, Ajayeta Rathi, P. Ragavan, Arvind Singh, Sanjeev Kumar
Black carbon (BC) has emerged as an integral part of the global carbon (C) cycle, constituting 12% ± 5% of the organic C pool in rivers and soils, with the potential to generate negative climate feedback. However, its ability to sequester C depends on the recalcitrant nature of BC in the environment, which is under debate. Using CTO-375 method and by measuring concentrations and isotopic compositions

Understanding the Cascade: Removing GCM Biases Improves Dynamically Downscaled Climate Projections Geophys. Res. Lett. (IF 5.2) Pub Date : 2024-05-04 Stefan Rahimi, Lei Huang, Jesse Norris, Alex Hall, Naomi Goldenson, Mark Risser, Daniel R. Feldman, Zachary J. Lebo, Eli Dennis, Chad Thackeray
Polarization surrounding bias correction (BC) in creating climate projections arises from its lack of physicality. Here, we perform and analyze 18 dynamical downscaling simulations (with and without BC) to better understand the physical impacts of BC, applied before downscaling, on regional climate output across the western United States. Without BC, downscaled precipitation is systematically and unrealistically
