The carbon budget for microbial EPS production in response to oil and Corexit for COAST, a mesocosm of coastal water with COASTal microbial concentrate

This dataset reports carbon content (as % of total weight), the stable isotopic carbon delta-13 composition and radiocarbon-14 values of the marine snow collected as the sediment of mesocosm tanks. Data were collected for four treatments: control (coastal seawater without the addition of oil or dispersants), WAF (water accommodated fraction), CEWAF (Corexit-enhanced WAF), DCEWAF (dilute CEWAF). This dataset also reports the oil concentration (EOE, estimated oil equivalency) measured in COAST for the three treatments that contain amended oil: WAF, CEWAF and DCEWAF. The dissolved organic carbon concentrations of three fractions from the water column for each treatment are included. The fractions are the permeate (< 3 kDa), colloid (3 kDa- 0.45 µm) and filtrate (< 0.45 µm).
