These data originate from soil samples collected on several field campaigns, aiming at identifying impacts of large herbivore activity on soil carbon storage and degradation in permafrost (northeastern Siberia (68.51 °N, 161.50 °E); campaign in July 2019) and seasonally frozen Arctic ground (northern Finland (69.15 °N, 27.00 °E); campaigns in September 2020 and June 2022).The samples were collected in transects across grazing intensity gradients, spanning over 5 different intensities:1 - no grazing / exclosure sites (Siberia: 23 years; Finland: 50 years)2 - occasional animal migration (Siberia: year-round; Finland: seasonal)3 - daily animal migration (Siberia: year-round; Finland: seasonal)4 - high-frequency daily animal migration (Siberia: year-round; Finland: seasonal)5 - pasture / supplementary feeding sites (Siberia: year-round; Finland: seasonal)Samples cover different ground types and seasonalities, which are marked out in the site names:B - drained thermokarst basinU - Yedoma uplandP - peatM - mineral ...
