Metadata summary of both gradients, Stora Amundön and Askimsbadet, with sampling sites 1-9. Here, C is the mass fraction of carbon, N is the mass fraction of nitrogen, d13C is the isotopic ratio of the 13C to 12C isotopes, d15N is the isotopic ratio of the 15N to 14N isotopes, FC is the isotopic amount of the fraction 13C/(12C+13C), FN is the isotopic amount of the fraction 15N/(14N+15N), and C/N is the ratio of carbon to nitrogen. Underlined numbers were outside of the calibration range.
