From: Linking optical and molecular signatures of dissolved organic matter in the Mediterranean Sea
Van Krevelen diagrams. Molecular formulae positively correlated with (a) peak C*, (b) peak T*, (c) a254*, (d) HIX and (e) BIX. Color scale represents the molecular weight. In the right-bottom corner of each panel is summarized the number of molecular formulae correlating, the percentage of peak intensity and the average molecular weight.
