Abstract Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse
set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes …

Winter conditions, such as ice cover and snow accumulation, are changing rapidly at
northern latitudes and can have important implications for lake processes. For example …

Winter is an important period for ecological processes in northern regions; however,
compared to other seasons, the impacts of winter climate on ecosystems are poorly …

The magnitudes of dissolved organic carbon (DOC) exports from boreal peatlands to
streams through lateral subsurface flow vary during the ice-free season. Peatland water …

One likely consequence of global climate change is an increased frequency and intensity of
droughts at high latitudes. Here we use a 17-year record from 13 nested boreal streams to …

Increasing concentrations of dissolved organic carbon (DOC) have been identified in many
freshwater systems over the last three decades. Studies have generally nominated …

Droughts influence dissolved organic carbon (DOC) export. DOC concentration and flux
dynamics during different propagation stages of hydrological drought (HD) are complex and …

Pools are common features of peatlands and can represent from 5% to 50% of the peatland
ecosystem's surface area. Pools play an important role in the peatland carbon cycle by …

High-latitude environments store approximately half of the global organic carbon pool in
peatlands, organic soils and permafrost, while large Arctic rivers convey an estimated 18–50 …

Abstract Changes may be occurring in the carbonate chemistry of fjords due to natural and
anthropogenic disturbance of major freshwater sources. We present a high‐frequency time …
