Permafrost degradation in Interior Alaska

This data collection includes soil chemical, soil physical, and soil microbiological data from 3 sites in central Alaska (Fairbanks Area). The data collection is subdivided into soil parmeters of soil profiles on the one hand, and more detailed data of aggregate and density fractions on the other hand. The data were collected as part of the CryoVulcan project and describe an intact permafrost site, a degraded permafrost site (wetted), and a degraded permafrost site (naturally drained).

Research domain: Soil Sciences

Research question: Development of soils after permafrost degradation, with a focus on changes in soil organic carbon stocks, depending on the hydrological situation of the degraded permafrost site (either wet/anoxic or dry/oxic). Novel approach is the quantification of soil organic carbon stocks in individual soil fractions.
