Terrestrial hydrology is central to the Arctic system and its freshwater circulation. Water
transport and water constituents vary, however, across a very diverse geography. In this …

Numerous components of the Arctic freshwater system (atmosphere, ocean, cryosphere, and
terrestrial hydrology) have experienced large changes over the past few decades, and these …

River inputs of nutrients and organic matter impact the biogeochemistry of arctic estuaries
and the Arctic Ocean as a whole, yet there is considerable uncertainty about the magnitude …

While river‐borne materials are recognized as important resources supporting coastal
ecosystems around the world, estimates of river export from the North Slope of Alaska have …

The Arctic freshwater cycle is changing rapidly, which will require adequate monitoring of
river flows to detect, observe, and understand changes and provide adaptation information …

Change dynamics of permafrost thaw, and associated changes in subsurface ow and
seepage into surface water, are analysed for different warming trends in soil temperature at …

Permafrost responses to a changing climate can affect hydrological and biogeochemical
cycling, ecosystems and climate feedbacks. We have simulated a model permafrost system …

Arctic coastal watersheds, though rarely monitored, are expected to have increased runoff,
as climate models predict more precipitation in the Arctic. This study provides a synthesis of …

This perspective paper argues for an urgent need to monitor a set of 12 concrete,
measurable indicators of food and water security in the Arctic over time. Such a quantitative …

Abstract Changes in river discharge and river water quality, due to climate change and other
drivers such as land cover change, pose both societal and ecosystem threats. Analyses of …
