The Permafrost Coastal Systems Network (PerCS-Net) will fill fundamental knowledge gaps associated with transforming permafrost coasts in the Arctic by linking over ten existing national and international networks. This international network of networks will develop protocols for quantifying and synthesizing information on the impacts occurring in coastal permafrost systems and promote synergy across networks to foster the next generation of researchers charged with identifying potential solutions to a rapidly changing Arctic System.

New Pan-Arctic Synthesis Paper Published in Nature Reviews

More than 10 PerCS-Net members collaborated on a recent review paper that was published in the journal Nature Reviews Earth & Environment in January 2022 highlighting the drivers, dynamics and impacts of changing Arctic coasts. The article is one of a collection of papers on Permafrost in a warming world published in January that examine the physical, biogeochemical, and ecosystem changes related to permafrost thaw and the associated impacts.

New European Space Agency Project Focused on Earth Observations for Permafrost-Dominated Arctic Coasts

Earth Observation for Permafrost dominated Arctic Coasts (EO4PAC) is a new effort funded by the European Space Agency (ESA) Polar Science Cluster to develop the next generation of the Arctic Coastal Dynamics database, a geospatial product on Arctic coastal erosion initially released in 2012. The focus of the two-year project is on complementation of in situ records with satellite data across the entire Arctic.
