Estimating meltwater retention and associated nitrate redistribution during snowmelt in an Arctic tundra landscape

Environmental Research Letters, 2020
Nitrogen availability in Arctic ecosystems is a key driver for biological activity, including plant, growth and thereby directly linked to the greening of the Arctic. Here, we model the redistribution of meltwater following spring snowmelt as well as the

Microbial and Geochemical Evidence of Permafrost Formation at Mamontova Gora and Syrdakh, Central Yakutia

Frontiers in Earth Science, 2021
Biotracers marking the geologic history and permafrost evolution in Central Yakutia, including Yedoma Ice Complex (IC) deposits, were identified in a multiproxy analysis of water chemistry, isotopic signatures, and microbial datasets.

Chemical and isotopic characteristics of a glacier-derived naled in front of Austre Grønfjordbreen, Svalbard [PDF]

Polar Research, 2012
The chemical and stable isotope composition of a glacier-derived naled in front of the glacier Austre Grønfjordbreen, Svalbard, is examined to elucidate how secondary processes such as preferential retention and leaching affect naled chemistry ...

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 ...

Glacier naled evolution and relation to the subglacial drainage system based on water chemistry and GPR surveys (Werenskioldbreen, SW Svalbard)

Annals of Glaciology, 2016
Glacier naledi are extrusive ice masses that appear in front of glaciers as a consequence of refreezing of meltwater seepage during the accumulation season.
