- 요약Cryopedology is the intersection of permafrost and soil science - assessing how ice formation affects soil development and function across spatial and temporal scales. As permafrost landscapes warm, understanding changes in soil physical and biogeochemical properties isn't just relevant for science-these properties affect infrastructure stability, ecosystem health, and nutrient cycles that support life in these regions. Our research tackles a critical challenge: turning qualitative observations into quantitative predictions. We've developed standardized methods to describe cryostructures and cryogenic soil structures in permafrost-affected soils, refined methods for estimating excess ice content for use in ground subsidence predictions and characterized how freeze/thaw cycles mobilize and affect the availability of essential nutrients, like Fe and P, across landscapes. In standardizing our methods for describing and measuring ice content, decades of legacy data can now be transformed into machine-readable formats, unlocking valuable information for modern climate models. In improving our understanding of nutrient dynamics, we can better anticipate changes in vegetation, water quality, and landscape stability across Arctic and subarctic regions. By integrating interdisciplinary perspectives across multiple scales-from how water freezes in individual soil pores to landscape-level transformations-this cryopedological research reveals the dynamic nature of permafrost-affected soils and demonstrates that predicting future changes requires detailed characterization of the physical and biogeochemical properties that govern ecosystem stability in rapidly evolving permafrost-affected landscapes.
