By integrating absorbance and fluorescence spectroscopy with FT-ICR-MS, we reveal unique DOM signatures including protein-rich chromophoric DOM with distinct absorbance shoulders, elevated protein-like fluorescent DOM components linked to P. antarctica degradation, and enrichment of labile low-molecular-weight compounds with increased sulfur-containing molecules from DMSP oxidation.
