Untargeted metabolomics analysis of dissolved organic matter in the western Atlantic Ocean

The data are dissolved organic compounds from three stations sampled in the western Atlantic Ocean in 2013. Seawater samples spanning from the surface ocean to the seafloor were collected, filtered, acidified, and extracted using solid phase extraction with Bond Elut PPL cartridges. The extracts were separated using reversed phase chromatography and analyzed with ultrahigh resolution mass spectrometry in negative ion mode. The resulting data are features, or a unique combination of mass-to -charge values and retention time.
