Earth's Future, Volume 14, Issue 9, September 2026.Abstract In alpine permafrost basins, dry‐season runoff largely depends on subpermafrost groundwater (BPG, deep groundwater), yet cryohydrogeological conditions are complicated by time‐varying hydrothermal regimes. Combined with the storage and regulation effects of permafrost on runoff, hydrograph‐based estimates of the fractional contribution of BPG ...

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.Abstract In this study, we present a mix of full‐depth profiles and near‐bottom observations of dissolved 230Th and 232Th from the Adélie Land margin in East Antarctica, a key site of Antarctic Bottom Water (AABW) formation. We show that the distribution of dissolved Th isotopes in this region is governed by a combination of reversible scavenging ...

Climate change in lowland Central America during the late deglacial and early Holocene [PDF]
The transition from arid glacial to moist early Holocene conditions represented a profound change in northern lowland Neotropical climate. Here we report a detailed record of changes in moisture availability during the latter part of this transition (11 ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The horizontal surface motions of the Earth's crust induced by glacial isostatic adjustment (GIA) are highly sensitive to lateral variations in Earth properties. We construct 3D GIA models by incorporating both varying elastic lithospheric thickness and lateral viscosity variations in the asthenosphere in a global, compressible, self ...

Persistent Warming and Reduced Freshening of the Abyssal Southern Ocean
Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.Abstract Antarctic Bottom Water has thinned, warmed, freshened, and spread more slowly into the global ocean since 1970. Yet, the physical drivers of these changes and their broader implications remain incompletely understood. Here we combine up‐to‐date observations (1985–2024) with ocean model simulations extending to 2050 to quantify ongoing and ...

Groundwater–surface water interactions across an arid river basin: spatial patterns revealed by stable isotopes and hydrochemistry [PDF]
Hydrology and Earth System SciencesA comprehensive understanding of groundwater–surface water (GW–SW) interactions is essential for managing water resources in arid regions, where hydrological processes are highly sensitive to climate variability and human activity.
