Evaporation (E) and transpiration (T) respond differently to ongoing changes in climate,
atmospheric composition, and land use. It is difficult to partition ecosystem-scale …

We used a model for permafrost hydrology informed by detailed measurements of soil ice
content to better understand the potential risk of abrupt permafrost thaw triggered by melting …

The presence of permafrost influences the flow paths of water through Arctic landscapes and
thereby has the potential to impact stream discharge and thermal regimes. Observations …

The future of forests and their productivity in dry environments will depend on both water
availability through precipitation and ecosystem and plant water use characteristics. It is …

Numerical simulations are essential tools for understanding the complex hydrologic
response of Arctic regions to a warming climate. However, strong coupling among thermal …

Abstract Study regions Hornsund, SW Spitsbergen, Svalbard–area representing atlantic
sector of High Arctic Study focus Svalbard's warming climate significantly alters its …

An increasing number of studies from high latitude settings use the stable hydrogen isotope
ratio (δ 2 H) of plant leaf waxes to quantify changes in past precipitation. Calibration of …

Rapid surface and subsurface changes in the Arctic polygonal tundra landscapes due to the
melting of ice wedges, known as thermokarst processes, have significant implications for …

Evapotranspiration (ET) is a key component in global water and energy cycles. This chapter
presents and discusses recent research advances about ET over northern regions and …

This study investigates the accuracy of the experimental models in two standard and
optimized cases using data from meteorological stations located on the northern and …
