Satellite‐Derived Volume Budget of Antarctic Sea Ice
Abstract In recent years, the Antarctic has seen a notable shift in sea ice trends: Where sea ice extent and volume were increasing on average, they have shown an unprecedented decline since 2016. Understanding the drivers of this shift is crucial to determining the impacts of climate change on sea ice and improving modeling of Antarctic sea ice ...

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 ...

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
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 ...

Abstract Retreating accretionary systems are common features of convergent plate margins. They are characterized by upper plate extension and backarc basin formation, which often forms diachronously and asymmetrically along‐strike. This study tests the hypothesis that this along‐strike variability in backarc basin formation is reflected in detrital and

Biases and Uncertainties in Radiosonde‐Based Precipitable Water Vapor
Abstract Precipitable water vapor (PWV) plays an important role in weather and climate phenomena. Accurate PWV measurements based on radiosonde observations are essential for assessing remote‐sensing measurements and long‐term trends. This study examines the performance of PWV algorithms, including their intrinsic biases and their sensitivity to ...

Abstract Atmospheric evaporative demand (AED) strongly influences drought intensification, vegetation stress, and wildfire risk. However, the meteorological triggers of regionally extreme AED remain poorly understood at the global scale. Here, we develop a physically constrained counterfactual attribution framework that combines the FAO56 Penman ...
