Description
Summary:This dataset contains soil pedon data collected in 2015 on Herschel Island (Qikiqtaruk; 69°34′N, 138°55′W), Beaufort Sea, Canada. Large amounts of soil organic carbon (SOC) are stored in high-latitude ecosystems. Knowledge on storage and variability provides essential base information to asses the vulnerability of this SOC. In total 38 soil pedons were sampled along transects in three typical tundra terrain types common across the Arctic region. These terrain types (unit) are hummocky tussock upland tundra (HT-Tundra), non-sorted circles on upland tundra (NSC-Tundra) and ice-wedge polygon terrain (IWP-Tundra). A main transect was set up with increasing sampling distance from the center and complemented with a shorter crossing transect. This aimed to maximize the distances between individual soil pedons in order to test geostatistical properties of SOC variability. At each pedon location a 1 m wide soil pit was sampled and described using a soil horizon oriented approach. The soil pit was then divided in 10 ...
