Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.Abstract Ice cores from Mt. Logan, the second highest peak in North America located in the St. Elias mountains in southwest Yukon, Canada, have provided conflicting accumulation records, thus the hydroclimate response to changing atmospheric conditions in the highest elevation regions is not well constrained.

Frontiers in Earth Science, 2022 Stable isotopes of Antarcticice cores are used extensively in reconstructing the past climate. Variations in snow accumulation patterns and post-depositional processes such as changes in isotope ratios due to diffusion may complicate these records.

Partitioning of evapotranspiration using a stable isotope technique in an arid and high temperature agricultural production system [PDF]
, 2017 Agricultural production in the hot and arid low desert systems of southern California relies heavily on irrigation. A better understanding of how much and to what extent irrigated water is transpired by crops relative to being lost through evaporation ...

Ecohydrology, Volume 19, Issue 1, January‐February 2026.ABSTRACT It is well established that changes in climatic conditions across Alpine environments have influenced tree‐growth at altitudes close to the tree line. Less well known is the impact that increasing proportions of glacial melt water, which may accompany increasing temperatures and otherwise drier conditions during warmer summers, have on the ...

Land Use Influence on the Characteristics of Groundwater Inputs to the Great Bay Estuary, New Hampshire [PDF]
, 2004 This research examines the sources and factors affecting nutrient-laden groundwater discharge to the Great Bay Estuary. To further understand this relationship, examination of groundwater residence time, a review of historic land uses, and nitrate source

Active geothermal systems with entrained seawater as analogues for low-sulphidation epithermal mineralization [PDF]
, 2005 The paradigm for low-sulphidation (LS) volcanic-arc associated mineralization is the active geothermal systems located along the Taupo Volcanic Zone (e.g. Broadlands). However, this analogue is inapt where fluid salinities are consistently in excess of 3.

Global Precipitation d‐excess Dataset: A Critical Resource for Geographical Science Research
Geoscience Data Journal, Volume 13, Issue 1, January 2026.This study builds d‐excess datasets using 98,423 stable isotope records, identifies significant variations in d‐excess across different climate types and time scales, and advances the application of iGCMs in geographical research. ABSTRACT As an indicator associated with dynamic non‐equilibrium fractionation and less affected by equilibrium ...

Deep Water Renewal in the Amerasian Basin Derived From Natural and Anthropogenic Tracer Data Sets
Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.Abstract The deep waters of the Amerasian Basin in the Arctic Ocean are among the most isolated in the modern Arctic Mediterranean Sea (e.g., Schlosser et al., 1997, https://doi.org/10.1016/s0168‐583x(96)00677‐5). In this study, we use a suite of tracers spanning a range of timescales—including chlorofluorocarbons (CFCs), SF6, radiocarbon (14C), and ...
