The Arctic is experiencing rapid environmental changes that present challenges to the natural environment, built environment, and social systems that have sustained Arctic peoples and ecosystems for generations. These changes are strongly evident in Arctic coastal systems. New research on Arctic coastal systems has been supported through both the Navigating the New Arctic (NNA) program and the Coastlines and People (CoPe) program. However, coordination and synthesis among these Arctic coastal projects and new perspectives are needed to fully understand these rapid changes.

Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. This research is needed to inform the economy, security and resilience of the Nation, the larger region, and the globe. NNA empowers new research partnerships from local to international scales, diversifies the next generation of Arctic researchers, enhances efforts in formal and informal education, and integrates the co-production of knowledge where appropriate.

Alaskan coastal Indigenous communities face severe, urgent, and complex social and infrastructural challenges resulting from environmental changes. Coastlines are degrading and this impacts infrastructure that communities use on a daily basis, changing how people access and hunt for food and other natural resources and conduct their lives. The magnitude and significance of impacts are unclear as is how local communities will respond to resulting disruptions and disasters.

Permafrost is ground that remains frozen for at least two consecutive years. It occurs under approximately one fourth of the northern hemisphere's land surface. In the far north, the permafrost is continuous across the landscape and contains large amounts of ice in its upper few meters. Thawing of permafrost has been observed at several locations across the Arctic in recent decades, yet the pan-Arctic extent of ice-rich permafrost and permafrost degradation is not fully described. This is because it is difficult to directly measure permafrost.

Shorefast ice (also known as landfast ice) is sea-ice that is attached to the coastline. Since it does not drift with the winds and currents, shorefast ice forms an important habitat for wildlife and a platform for human subsistence food production and transport in the Arctic. As the climate warms, residents local to the Arctic report that it is breaking up earlier in the year and is thinner than it was a few decades ago. These environmental changes threaten the sustainability of wildlife and traditional human activities that depend on shorefast ice.

The Permafrost Coastal Erosion-RCN (PCE-RCN) will bring together leaders in fields of natural and social science and engineering to address the challenges faced by coastal communities in the Arctic due to rapid coastal erosion. Rapid coastal erosion can force communities to consider moving inland and limit access to resources. One goal of the proposed PCE-RCN will be to better understand the challenges associated with coastal erosion, which is driven by permafrost thaw and changing sea ice conditions.
