Biodegradable dissolved organic carbon (BDOC) constitutes the most labile fraction of
dissolved organic matter (DOM), which also functions as a source of CO 2 emissions from …

This paper reviews the impacts of permafrost change on hydrological and related
hydrochemical, particulate and organic fluxes in small Arctic catchments. While the …

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

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 …

As the permafrost region warms, its large organic carbon pool will be increasingly
vulnerable to decomposition, combustion, and hydrologic export. Models predict that some …

As high latitudes warm, a portion of the large organic carbon pool stored in permafrost will
become available for transport to aquatic ecosystems as dissolved organic carbon (DOC). If …

Northern permafrost soils store a vast reservoir of carbon, nearly twice that of the present
atmosphere. Current and projected climate warming threatens widespread thaw of these …

Ongoing climate warming in the Arctic will thaw permafrost and remobilize substantial
terrestrial organic carbon (OC) pools. Around a quarter of northern permafrost OC resides in …

Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the
Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic …
