This dataset contains data used for the paper "The impact of freeze-thaw history on soil carbon response to experimental freeze-thaw cycles". The Related References field will be updated with a full citation when available. Freeze-thaw is a disturbance process in cold regions where permafrost soils are becoming vulnerable to temperature fluctuations above 0˚C. Freeze-thaw alters soil physical and biogeochemical properties with implications for carbon persistence and emissions in Arctic landscapes. We examined whether different freeze-thaw histories in two soil systems led to contrasting biogeochemical responses under a laboratory-controlled freeze-thaw incubation. We investigated controls on soil organic matter (SOM) composition through Fourier-transform ion cyclotron resonance mass spectroscopy (FT-ICR-MS) to identify nominal carbon oxidation states and relative abundances of aliphatic-type carbon molecules in both surface and subsurface soils. Soil cores (~ 60 cm-depth) were sampled from two sites in Alaskan permafrost landscapes with different in situ freeze-thaw characteristics: Healy (>40 freeze-thaw cycles annually) and Toolik (<150 freeze-thaw cycles annually). FT-ICR-MS was coupled with in situ temperature data and soil properties (i.e., soil texture, mineralogy) to assess (1) differences in SOM composition associated with previous freeze-thaw history and (2) sensitivity to experimental freeze-thaw in the extracted cores. Control (freeze-only) samples showed greater carbon oxidation in Healy soils compared with Toolik, even in lower mineral horizons where freeze-thaw history was comparable across both sites. Healy showed the most loss of carbon compounds following experimental freeze-thaw in the lower mineral depths, including a decrease in aliphatics. Toolik soils responded more slowly to freeze-thaw as shown by intermediary carbon oxidation distributed across multiple carbon compound classes. Variations in the response of permafrost carbon chemistry to freeze-thaw is an important factor for predicting changes in soil function as permafrost thaws in high northern latitudes.

The Toolik core collection site (lat 68.66045, lon -149.37013) is located in tussock tundra in the Arctic foothills of the Brooks Range. Toolik falls within the Philip Smith Mts. quadrangle (Quaternary) composed of unconsolidated surficial alluvial and glacial deposits (Brosgé et al., 2001; Wilson et al., 2015). Vegetation includes dwarf shrubs, sedge, and herbaceous plants. Species include Eriophorum vaginatum (tussock cottongrass), Carex sp. (true sedges), and Vaccinium vitis-idaea (lingonberry) (National Ecological Observatory Network, 2019). The soils at the sampling location were mapped as Typic Histoturbels, which are soils with thick organic horizons that present evidence for cryoturbation and permafrost in the subsurface (National Ecological Observatory Network, 2019). The Healy core collection area (lat 63.87980, lon -149.21539) occurs in a tussock tundra in central Alaska that is dominated by dwarf shrubs and sedge meadows (National Ecological Observatory Network, 2019). Species include Betula glandulosa (American dwarf birch), Picea glauca (white spruce), and Ledum palustre (marsh Labrador tea) (National Ecological Observatory Network, 2019). The site falls within the Healy quadrangle and has been characterized as Nenana Gravel (Tertiary, Pliocene, and upper Miocene) with a composition of poorly to moderately consolidated conglomerate and coarse-grained sandstone with interbedded mudflow deposits and thin claystone layers, and local thin lignite beds (Csejtey et al., 1992; Wilson et al., 2015). Similar to Toolik, the soils at the sampling location were also classified as Typic Histoturbels (National Ecological Observatory Network, 2019).
