Exopolymeric substances (EPS) composition in colloidal fraction, suspended particulate matter and sinking marine snow or marine oil snow during a long term coastal phytoplankton seeded mesocom experiment

This dataset contains measurements of organic carbon (OC), neutral sugar, uronic acid, and protein concentrations in three fractions: colloidal fraction (3 kDa- 0.4 µm), suspended particulate matter (SPM, > 0.4 µm) and sinking marine oil snow or marine snow (MOS/MS). These measurements are from a mesocosm experiment conducted under multiple conditions such as: oil and dispersant (Corexit) were added to seawater inoculated with plankton concentrates and control where there was no addition of oil or dispersant.
