Molecular dissimilarity of DOM from different environments on different compositional levels. Bray–Curtis dissimilarity based on relative FT-ICR-MS signal intensities of a all detected, unfragmented molecular formulae in full range mass spectra (n = 6166) and b common molecular formulae in full range mass spectra (n = 2531). c Bray–Curtis dissimilarity based on relative FT-ICR-MS signal intensities of fragments (n = 324) of the most intense common molecular formulae (n = 54) that were selected for fragmentation experiments.
