Continental margin systems collectively receive and store vast amounts of organic carbon
(OC) derived from primary productivity both on land and in the ocean, thereby playing a …

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 …

Soil erosion, physical transport of soil over the landscape by alluvial and aeolian processes
as source of energy, has a strong impact on the global carbon cycle (GCC). Being a light …

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 …

Release of greenhouse gases from thawing permafrost is potentially the largest terrestrial
feedback to climate change and one of the most likely to occur; however, estimates of its …

Permafrost thaw has been widely observed to alter the biogeochemistry of recipient aquatic
ecosystems. However, research from various regions has shown considerable variation in …

The sediments of the pan-Arctic shelves contribute an important component to the Arctic
Ocean ecosystem by providing a habitat for biota (benthos), a repository for organic and …

The burial of terrestrial organic carbon (terrOC) in marine sediments contributes to the
regulation of atmospheric CO2 on geological timescales and may mitigate positive feedback …

Arctic rivers provide an integrated signature of the changing landscape and transmit signals
of change to the ocean. Here, we use a decade of particulate organic matter (POM) …

Permafrost is thawing extensively due to climate warming. When permafrost thaws,
previously frozen organic carbon (OC) is converted into carbon dioxide (CO2) or methane …
