Impact of Corexit on aggregation of Skeletonema grethae or natural particles in oil contaminated natural seawater, low oil concetrations: Rolling table experiment to test the aggregation of diatoms, TEP (transparent exopolymers), POC (particulate organic carbon) as a function of the presence of Cor

Testing the direct effect of Corexit when added to oil contaminated natural seawater on aggregation of diatoms. Once aggregates had formed samples were collected separately from the surrounding seawater and the marine snow fraction.
