Molecular network of the Trichodesmium bloom extract. Only halogenated molecules are shown in the network. Color-coding of halogenation pattern is as follows: green = Cl, cyan = 2 × Cl, and pink = ClBr. Node size is proportional to LC-MS peak area. Previously reported compounds and newly reported molecules (1–4) are shown as square nodes and abbreviated by name (Cotz, conulothiazole; Ictz, isoconulothiazole; Samd, smenamide; Tphy, trichophycin; Itph, isotrichophycin; Slac, smenolactone; Smtz, smenothiazole). Circular nodes are currently uncharacterized metabolites.
