Under a warming climate, degrading permafrost profoundly and extensively affects arctic
and alpine ecology. However, most existing relevant studies are more focused on the …

Abstract Sulphate (SO 4 2-) concentrations in freshwaters have increased globally over the
last decades even though a strong reduction in atmospheric sulphur (S) deposition has …

Dissolved organic matter (DOM) plays a significant role in aquatic biogeochemical
processes and the carbon cycle. As global climate warming continues, it is anticipated that …

Lake ecosystems and the services that they provide to people are profoundly influenced by
dissolved organic matter derived from terrestrial plant tissues. These terrestrial dissolved …

Abstract The Arctic Ocean is a fundamental node in the global hydrological cycle and the
ocean's thermohaline circulation. We here assess the system's key functions and …

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 …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

Climate change induced permafrost thaw in the Arctic is mobilizing ancient dissolved
organic carbon (DOC) into headwater streams; however, DOC exported from the mouth of …

Rivers integrate processes occurring throughout their watersheds and are therefore
sentinels of change across broad spatial scales. River chemistry also regulates ecosystem …

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 …
