Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

open access: yesBasin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Impact Crater Hydrothermal Systems Support Rapid Microbial Enrichment and Diverse Metabolic Potential

open access: yesGeobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.

Distributions of Short‐Duration High‐Intensity Precipitation Events in the United States Under Intermediate and Pessimistic Climate Change Scenarios

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Under a warming climate, the magnitude and frequency of intense precipitation are expected to increase globally, on average. However, changes in the regional variability of short‐duration high‐intensity (SDHI) precipitation across the contiguous United States—both temporally and spatially—remain uncertain, and most projections rest on ...

Constraining Fault Kinematics and India‐Tarim Convergence Partitioning in Southwestern Tibet With Geodetic Block Modeling

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract How the convergent strain between the India Plate and the Tarim basin is partitioned by active faults and off‐fault deformation in southwestern Tibet is poorly understood due to limited knowledge of strain localisation and fault kinematics. In this study, we derive high‐resolution velocity fields for the southwestern Tibetan Plateau using both

A Radio Science Experiment for Dragonfly to Investigate Titan's Rotation and Interior Structure

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract NASA's mission Dragonfly to Titan is scheduled for launch in 2028 with arrival in 2034 to study Titan's prebiotic chemistry and habitability. We propose a radio science experiment for Dragonfly, in which radiometric tracking of the rotorcraft from the Deep Space Network, already baselined for communications and navigation, is used as a ...

Measurements of the Size and Physical Properties of Marine Particles Using Atomic Force Microscopy: Implications for Marine Biogeochemical Cycles

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Particle size and physical properties such as stiffness and adhesiveness affect sinking velocity and flux in the ocean, yet conventional two‐dimensional measurements lack accuracy and mechanical information. In this study, we applied atomic force microscopy (AFM) to quantify three‐dimensional size and physical properties of marine particles ...
