Generation and Preservation of Submarine Terraces: Insights From Records Imprinted on the Topography of Dokdo Volcano

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Marine terraces archive sea‐level and tectonic history, yet their relationship to individual highstands remains contentious. While most studies focus on subaerial terraces in uplifting settings, submerged terraces in subsiding settings are less explored. We develop a 1‐D wave‐erosion model and apply it to Dokdo — a subsiding volcanic island in

Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...
