Petrocarbon incorporation into marine snow in three mesocosm experiments and the exopolymeric substances (EPS) composition

This dataset is for extracellular polymeric substances (EPS) composition from three mesocosms (M3: GOMCOAST, M4: GOMOO and M5: LTMOSE) and petrocarbon measurement of sinking marine snow. Measurements in the mesocosms include particulate organic carbon concentration of the sinking marine snow (%, wt), petrocarbon percentage, non-petrocarbon percentage, as well as the concentrations of neutral sugar, uronic acid, and protein of both particulate and colloidal EPS concentration. Other related datasets from a mesocosm experiment with COASTal water with coastal microbial concentrate, COAST (M2) are available under GRIIDC Unique Dataset Identifiers (UDIs): R4.x263.000:0003 (DOI: 10.7266/N7SF2T7V) and R4.x263.000:0028 (DOI: 10.7266/N7WM1BHX).
