In situ nuclear magnetic response of permafrost and active layer soil in boreal and tundra ecosystems
Characterization of permafrost, particularly warm and near-surface permafrost which can contain significant liquid water, is critical to understanding complex interrelationships with climate change, ecosystems, and disturbances such as wildfires. Understanding the vulnerability and resilience of per...
