Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]

, 2017
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, Volume 55, Issue 2, Page 454-475, April 2026.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Simulation of benzene transport and biodegradation during transient hydraulic conditions [PDF]

, 2000
Thesis (M.S.) University of Alaska Fairbanks, 2000MODFLOW and BIOMOC were used to simulate transport and biodegradation of benzene in the alluvial aquifer adjacent to the Chena River. MODFLOW was used to calculate ground water fluxes at the boundaries of

Dynamic Lake Ice Conditions Shape Caribou Water‐Crossing Behavior in the Arctic

Global Change Biology, Volume 32, Issue 4, April 2026.
Seasonally dynamic ice conditions regulate migratory connectivity in Arctic caribou. In spring, intermediate ice conditions permit direct lake crossings until a behavioral threshold in surface albedo is reached (APR ≈0.56), whereas in fall, ice‐free conditions act as barriers and promote circumnavigations around lakes.

Projected Methane Emissions From a Boreal Thermokarst Bog Are Sensitive to Carbon Substrate Availability, Distribution, and Transport Pathway Dominance

Global Change Biology, Volume 32, Issue 4, April 2026.
Projected radiative forcing from a thermokarst bog in Boreal Alaska depends on methane emission transport pathway dominance, with aerenchyma‐ and diffusion‐dominant causing net warming and ebullition‐dominant causing net cooling. Predicted methane shows a transient response as air temperature increases in future projections causing soil drying and ...

A novel experimental platform to monitor solid/water interfaces under freeze–thaw cycles

Journal of Microscopy, Volume 302, Issue 1, Page 92-99, April 2026.
Abstract We design and implement an original experimental platform resting on Atomic Force Microscopy (AFM) to capture nanoscale insights into key characteristics of solid/water interfaces subject to freeze–thaw conditions. The work is motivated by the observation that freezing and thawing underpin a variety of processes in the context of, e.g ...
