The files stored in this repository contain data and additional information for the study "Long-term geothermal warming reduced stocks of carbon but not nitrogen in a subarctic forest soil" by Tino Peplau, Julia Schroeder, Edward Gregorich and Christopher Poeplau. climate-data-takhini.txt: Contains a dataset with climate data used for Figure 1a and b. The data was downloaded from https://climatedata.ca/download/ as single variables and later on put into this single file. degree_days.xlsx: Contains soil temperature data with according calculation of cumulative degree days. temperature.xlsx: Contains raw data of soil temperature teabags_HS.xlsx: Contains information about all 24 buried teabags. The table contains 6 columns: 1)"sample" gives the individual name of the sample. 2) "rep" is the replication at each plot 3) "plot" is the plot, according to the soil warming intensity 4) "depth" is the depth at which the teabag was buried 5) "weight_start" is the weight of tea before at start of the experiment 6) "weight_end" ist the weight of the tea after one year of burial HS_data_final.xlsx: Contains all data of the soil samples. It is divided into two sheets: "sample_data": Provides information about every single soil sample, including chemical data, bulk density, organic and inorganic carbon, nitrogen and fractions. "plot_data": Provides a summary of the data for every soil core (repetition) and plot, including mass corrected SOC and N stocks of the whole profile, topsoil and subsoil.

This study is part of the "Breaking the Ice" project funded by the German Research Foundation, grant number 401106790. Funding for E.G. was provided by the Science & Technology Branch of Agriculture & Agri-Food Canada [Project J-001756 "Biological Soil Carbon Stabilization"].
