The American Geophysical Union (AGU) is accepting abstracts for their Fall Meeting. This conference will take place 13-17 December 2021 in New Orleans, Louisiana and online.
The following sessions invite abstracts:
GC079: Social, Ecological, and Infrastructure Consequences of Permafrost Degradation
Conveners: Alexander L. Kholodov, Vera Kuklina, and Susan Natali
Permafrost degradation plays a very important role in the functioning of ecosystems, biogeochemical cycles, surface and subsurface hydrology and eventually affects human life in high latitudes causing infrastructure damage, reducing accessibility to subsistence resources, and contributing to climate change. This session is dedicated to studies of multiscalar dimensions of the societal, environmental, and infrastructure changes associated with thawing permafrost from the level of a single community to the regional and global scale. Conveners invite experts both in social and natural studies including environmental sciences, hydrology, biogeochemistry, geography, and anthropology, to share their findings and discoveries in the research of ongoing permafrost-related transformations in the regions of Arctic and Sub-Arctic. Conveners also solicit contributions dealing with the engineering issues and solutions aimed to offset infrastructure damage due to permafrost degradation.

Session NS003: Cryogeophysics: Emerging Technologies for Sensing Dynamic Cold Region Environments
Conveners: Dan R. Glaser, Anna M. Wagner, and Baptiste Dafflon
The environmental and engineering implications of climate change are evident around the globe, but most notable in the polar and sub-polar regions where impact to local communities is direct and acute. Infrastructure designed for this environment requires mitigation to address dynamic surface and subsurface conditions including the thawing, flooding, and erosion of permafrost. This session aims to promote novel and emerging near-surface geophysical technologies within the cryosphere at varying scales for addressing such problems as geo-hazard identification and sensitivity, permafrost mapping, and siting for civil infrastructure, ice road integrity, stream crossings, earthen dam integrity, sub-arctic landfill contaminant mapping, geothermal energy development, and crevasse mapping for polar mobility. Geophysical technologies like electrical resistivity tomography (ERT), ground-penetrating radar (GPR), electromagnetic induction (EMI), nuclear magnetic resonance (NMR), seismic, distributed sensor networks, and fiber optic sensing offer the ability to inspect, image, and monitor the subsurface allowing unique insights for surmounting this ever-present problem.

Session B074: The Resilience and Vulnerability of Arctic and Boreal Ecosystems to Climate Change
Conveners: Peter C. Griffith, Michelle C. Mack, Abhishek Chatterjee, and Natalie Boelman
Climate change is unfolding faster in the high northern latitudes than anywhere else on Earth. These changes are impacting ecological processes directly, through warmer temperatures and changing precipitation, and indirectly, though increasing frequency of climate-driven disturbances such as wildfire, outbreaks of pests and pathogens, and permafrost thaw. Although some ecosystems are resistant or resilient to these changes, many are shifting to new states, altering the function of the Arctic-boreal region. This session invites contributions in terrestrial ecology and carbon cycle science that provide conceptual, regional, or global insights into the resilience and vulnerability of the Arctic-boreal region, including its wildlife and ecosystem services, to changing climate. Contributions may address any geographic area of this region. Conveners welcome studies that use in situ, airborne, and satellite remote sensing observations, and models, or some combination thereof, to conceptualize, detect, predict, or forecast the changing function of this region in the earth system.
