The dataset contains the results of the analysis of the snow isotopic composition spatial variability in the Kasmala River basin (southern West Siberia). The dataset includes raw data on the isotopic composition of snowpack samples, topographic characteristics, land cover parameters, and the R code for regression and ANOVA analyses. The dataset was created to support the publication of "Variability in snowpack isotopic composition between open and forested areas in the West Siberian forest steppe"" (submitted)


Steps to reproduce

The file kasmalaisotopdata.rds contains the data needed to analyze the spatial differences in the snow isotopic composition. The CSV file with the same name duplicates the contents of the dataset. Fields: cname: factor; sampling point index Lon: Longitude of point Lat: latitude of the point Year: year of sampling O18: δ18O d_excess: deuterium excess D : δ2H Transect: Transect number SDepth: snow thickness (cm) SWE: snow water equivalent (mm) Catchment_part: factor; index of part of the basin (NP-northern, CP-central, SP-southern) Forest_ratio : fraction covered by forest within 200 m LC_type: Factor; main land cover type (arable, deciduous, pine forests) Aspect_SRTM: slope exposure in degrees General_curv_SRTM: general curvature index. Ruggedness: dissection of the slope. Slope_SRTM: slope angle in degrees O18_cor: corrected value of O18 by IQR method D_cor: corrected H2 value by IQR method Pershin_iso_Kasmala.R contains R code for the analysis.
