Drivers of Dissolved Thorium Isotope Distributions Along the Adélie Land Margin, East Antarctica: The Roles of Reversible Scavenging, Conservative Transport, and Lithogenic Supply

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 ...

GIA‐Induced Mantle Circulation and Surface Horizontal Motions in North America: Effects of 3D Laterally Varying Elastic Thickness and Viscosity

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 ...

Systematic Ocean Ventilation Biases in Climate Models Indicated by Chlorofluorocarbon‐12

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract An accurate representation of ocean ventilation in models is crucial for simulating ocean uptake of heat and carbon, as well as the ocean's supply of oxygen. Using the Inverse Gaussian Transit Time Distribution technique, we assessed ocean ventilation in current climate models via comparing water ages —defined as the time since last contact ...

Simultaneous Megapluvials in Southwestern North and South America During the Last Millennium

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Earth's climate has experienced prolonged hydroclimatic extreme events that can manifest decadal or longer anomalies. Such events can shape ecological systems and human societies. Decadal‐scale droughts, megadroughts, occurred in southwestern North and South America (North American Southwest, NASW; South American Southwest, SASW) over the past
