Entropy and seasonal isotopic duality reveal the sustainability paradox of the upper Ganga River [PDF]

Scientific Reports
Mountain headwaters are widely regarded as pristine reference systems; however, mounting evidence reveals that even these fragile environments are no longer insulated from the pervasive influence of the Anthropocene.

The Contrasting Role of Marine- and Land-Terminating Glaciers on Biogeochemical Cycles in Kongsfjorden, Svalbard. [PDF]

Global Biogeochem Cycles
Abstract This case study of Kongsfjorden, western coastal Svalbard, provides insights on how freshwater runoff from marine‐ and land‐terminating glaciers influences the biogeochemical cycles and distribution patterns of carbon, nutrients, and trace elements in an Arctic fjord system.

Geological and glacial-hydrologic controls on chemical weathering in the subglacial environment

Annals of Glaciology, 2022
A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

Examining the variability of rock glacier meltwater in space and time in high-elevation environments of Utah, United States

Frontiers in Earth Science, 2023
Rock glaciers are common geomorphic features in alpine landscapes and comprise a potentially significant but poorly quantified water resource. This project focused on three complementary questions germane to rock glacier hydrology: 1) Does the ...

Transformation characteristics of the large-flow river and groundwater in the fault zone in the glacier-covered area of Bomi in Tibet

Shuiwen dizhi gongcheng dizhi, 2021
The Bomi section of the Sichuan-Tibet Railway passes through the glacier-covered area where multiple large-scale river compounded with faults occur. The river water is abundant, leading to a tectonic high-pressure water inrush and mud outburst disaster ...

Mechanism for the subglacial formation of cryogenic brines

Annals of Glaciology, 2022
Cryogenic brines are under-studied, despite the fact that they may contain information about past ice-sheet behavior. Cryogenic brines form through cryoconcentration of seawater, although the specific setting and mechanism of formation have been debated.

Changes in meltwater chemistry over a 20-year period following a thermal regime switch from polythermal to cold-based glaciation at Austre Brøggerbreen, Svalbard [PDF]

Polar Research, 2014
Our long-term study gives a rare insight into meltwater hydrochemistry following the transition of Austre Brøggerbreen from polythermal to cold-based glaciation and its continued retreat. We find that the processes responsible for ion acquisition did not
