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 …

Land degradation has become one of the biggest environmental challenges human society
is currently facing, which is why understanding the global pattern of this land crisis is …

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 …

Enhanced warming of the Northern high latitudes has intensified thermokarst processes
throughout the permafrost zone. Retrogressive thaw slumps (RTS), where thaw-driven …

Arctic warming alters land‐to‐sea fluxes of nutrients and organic matter, which impact air‐
sea carbon exchange. Here we use an ocean‐biogeochemical model of the southeastern …

Arctic coastal permafrost erosion is projected to increase by a factor of 2–3 by 2100.
However, organic matter fluxes from the coastal permafrost into the ocean have not been …

Warming air and sea temperatures, longer open-water seasons and sea-level rise
collectively promote the erosion of permafrost coasts in the Arctic, which profoundly impacts …

The Arctic rapidly warms and sea ice retreats, a large fraction of organic carbon (OC),
currently stored in coastal permafrost will be released into the marine system. Once …

Groundwater discharge is an important mechanism through which fresh water and
associated solutes are delivered to the ocean. Permafrost environments have traditionally …
