Session ID#: 13163

Session Description:
Permafrost dynamics have become a focal point of arctic research due to their wide-ranging impacts and feedback mechanisms within the Earth system. In addition to global climate regulation, ecosystem services performed by permafrost landscapes support subsistence practices (including human land-use), transportation corridors, and infrastructure that are of fundamental importance to northern communities. Thus, there is an urgent need to (1) enhance the understanding of permafrost resilience and degradation processes, and (2) combine physical, ecological, and social sciences in permafrost research.

This session highlights the impacts of permafrost dynamics and landscape change on northern environments and peoples. We invite studies about the implications of degrading permafrost for northern communities, infrastructure, wildlife, and the storage, vulnerability and release of carbon and nitrogen in permafrost. We welcome research based on field-process studies, monitoring programs, remote sensing and modeling approaches, as well as interdisciplinary efforts including traditional knowledge and local observations on this topic.
