Elucidating the Biogeochemical Memory of the Oceans by Means of High-Resolution Organic Structural Spectroscopy
Non target high resolution organic structural spectroscopy (high-field FTICR mass spectrometry and NMR spectroscopy) of marine dissolved organic matter (DOM) isolated by means of solid phase extraction (SPE) from four different depths representative of oceanic regimes of global significance in the Angola basin,South Atlantic Ocean,provided molecular level information of complex unknowns with unprecedented coverage and resolution.The most intriguing of the many new findings is the excess abundance of olefinic unsaturation in marine DOM compared with that of aromatic unsaturation for both proton and carbon chemical environments.This advanced resolution and coverage offers novel opportunities for the traceability of the biogeochemical heritage of the oceans.
