Rapid atmospheric warming since the mid-twentieth century has increased temperature-
dependent erosion and sediment-transport processes in cold environments, affecting food …

Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

Arctic coasts are vulnerable to the effects of climate change, including rising sea levels and
the loss of permafrost, sea ice and glaciers. Assessing the influence of anthropogenic …

Net primary production (NPP) is the foundation of the oceans' ecosystems and the fisheries
they support. In the Arctic Ocean, NPP is controlled by a complex interplay of light and …

Arctic coastal erosion damages infrastructure, threatens coastal communities and releases
organic carbon from permafrost. However, the magnitude, timing and sensitivity of coastal …

Coastal wetlands, such as saltmarshes and mangroves that fringe transitional waters,
deliver important ecosystem services that support human development. Coastal wetlands …

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

As a contribution to the Regional Carbon Cycle Assessment and Processes phase 2
(RECCAP2) project, we present synthesized estimates of Arctic Ocean sea‐air CO2 fluxes …

Eroding permafrost coasts are likely indicators and integrators of changes in the Arctic
System as they are susceptible to the combined effects of declining sea ice extent, increases …

The degradation of ice-rich permafrost deposits has the potential to release large amounts of
previously freeze-locked carbon (C) and nitrogen (N) with local implications, such as …
