  abstract = {{T}o chemically differentiate the three pelagic {S}argassum morphotypes co-occurring in floating rafts and drifting across the {A}tlantic {O}cean before stranding on {W}est {A}frican, {C}aribbean, and {A}tlantic {M}exican coastlines, we conducted an investigation of their metabolomic profiles. {H}ydroethanolic extracts from open-sea raft specimens were analyzed using liquid chromatography-tandem mass spectrometry ({LC}-{MS}2), and the resulting spectra were processed through feature-based molecular networking with {M}et{G}em software. {S}everal glycolipids were putatively identified through spectral matching and manual annotation, predominantly associated with {S}. natans var. wingei, {S}. natans var. natans, and {S}. fluitans var. fluitans. {T}hese findings were corroborated by statistical analyses of 1{H} {NMR} spectral fingerprints. {T}his study represents a chemotaxonomic assessment of pelagic {S}argassum utilizing molecular networking, demonstrating its efficient utility for putative chemomarker identification. {W}e further discuss the taxonomic status of the three varieties in light of our chemical data, along with observed physiological distinctions among the morphotypes.},
