Impact of Corexit on aggregation of old Chaetoceros: Rolling table experiment to test the aggregation of diatoms, TEP(transparent exopolymers), POC(particulate organic carbon) as a function of oil and oil+Corexit

Testing the direct effect of oil or oil+Corexit on aggregation of diatoms. Once aggregates had formed samples were collected separately from the surrounding seawater and the marine snow fraction. In contrast to the earlier experiment cells were older and initial TEP concentration higher.
