Marine gels, extracellular polymeric substances (EPS) and transparent exopolymeric particles (TEP) in natural seawater and seawater contaminated with a water accommodated fraction of Macondo oil surrogate

This dataset contains laboratory characterization and comparisons of extracellular polymeric substances (EPS) and transparent exopolymeric particles (TEP) from various mesocosms and bottle experiments (microcosms). Measurements in the mesocosms include organic carbon concentrations for particulate (POC), colloidal (COC), and dissolved (DOC) size fractions, as well as concentrations for particulate EPS, TEP, colloidal EPS contributed C, and the percent contribution of colloidal EPS to total EPS. In the microcosms, the EPS composition and method comparison contains particulate EPS composition in terms of the concentrations of neutral sugar, uronic acid, protein, TEP, and gel. Additionally, the colloidal phase of these components are also quantified and compared the colloidal EPS Nuclear magnetic resonance (NMR) assignment (%).
