Two Metrics Describing the Causes of Seasonal and Spatial Changes in Subglacial Aqueous Chemistry

Frontiers in Earth Science, 2018
Seasonal change in surface melt input and spatial controls on the distribution of subglacial water can cause considerable variability in the aqueous chemistry of subglacial waters.

Microfabric controls on the preservation and erosion of Late Pleistocene freshwater microbialites in northwestern Patagonia, Argentina

The Depositional Record, Volume 12, Issue 4, September 2026.
Microfabric distribution controls porosity, preservation and erosion in Late Pleistocene microbialites from the Maquinchao Basin (Argentina). Differential preservation of laminated and shrub fabrics shapes the present morphology of the carbonate build‐ups and influences their palaeoenvironmental interpretation.

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]

, 2016
Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

Warm‐wet transition restructures arid lake microbiomes and functional potential

iMetaOmics, Volume 3, Issue 3, September 2026.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,

Quantifying Deep Groundwater Contributions to Streamflow With Inequality‐Constrained EEMMA From Sparse Isotope Series in Alpine Permafrost Basins

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 ...

A distributed energy-balance melt model of an alpine debris-covered glacier [PDF]

, 2014
Distributed energy-balance melt models have rarely been applied to glaciers with extensive supraglacial debris cover. This paper describes the development of a distributed melt model and its application to the debris-covered Miage glacier, western ...

Conserving the World's Specialist Riverine Birds

WIREs Water, Volume 13, Issue 4, July/August 2026.
Specialist riverine birds constitute a diverse bird group globally, highly adapted to rivers and streams. They are at risk from multiple threats to rivers, riparian zones and river catchments including impoundment, hydropower and abstraction; land‐use changes including urbanization and agricultural intensification; traditional and emerging pollutants ...

Anomalous Sample Detection Tool and Its Application in Identifying Interbasin Groundwater Flow in the Yarlung Zangbo River Basin, Tibetan Plateau

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Interbasin groundwater flow (IGF) is increasingly recognized as an important but difficult‐to‐diagnose component of regional groundwater flow systems. Recent studies highlight that major rifts within the Yarlung Zangbo River Basin (YZRB) may facilitate IGF, but the role of all six major rifts remains unclear.
