Fig. 5

A Metabolite abundance presented as mole fraction of carbon of total identified metabolites [134] across the incubation and field samples. Average of triplicates are shown. The most abundant 15 molecules for each sample are color-coded, with “all others” (gray) containing the sum of the remaining quantified metabolites [119]. Total quantified metabolite concentration as the percentage of (B) particulate organic carbon (POC) and (C) particulate nitrogen (PN), where error bars represent standard deviation of the mean (n = 3). For all plots, y-axis break separates incubation treatment samples on the top and field samples on the bottom. For (B) and (C), color denotes incubation (pink) versus field (aqua) samples. Full data available in Table S11; individual metabolite contributions as %POC and %PN, available in Figs. S8 and S9, respectively. Note that we do not have POC or PN to pair with sea-ice field samples.
