Purpose: Permafrost thawing of northern peatlands can cause the local collapse of peat plateaus into much wetter thermokarst bogs and fens, dominated by Sphagnum mosses and graminoids, respectively. However, permafrost thaw can also improve landscape drainage and, thus, lead to the regional drying of peatlands. How gradual drying of these thawing permafrost peatlands affects the subsequent microbial production of carbon dioxide (CO2) and nitrous oxide (N2O) is uncertain because of landscape heterogeneity in moisture, peat quality, and vegetation.
Abstract: Data collected from Lutose, Alberta surface peat permafrost samples. Samples were collected across two transect locations representing a space-for-time continuum in permafrost thaw. Collected samples were incubated in the lab under either field moisture or gradual drying. During the incubation, headspace CO2, 13C-CO2, and N2O were collected. At the same time, peat ammonium, nitrate, moisture and 13C and 15N were collected.
