Roller Tank Experiment for the component-specific Investigation of Oil Incorporation into Marine Oil Snow with a Phytoplankton Mixture (t = 4 days)

This roller tank experiment investigated the partitioning of different oil compounds (n-alkanes and polyaromatic hydrocarbons) between sinking marine oil snow, the unaggregated particles in the surrounding seawater and the dissolved water phase. Moreover, the effect of the dispersant Corexit on the occurring processes was investigated. For this experiment, a mixture of different planktonic organisms (mainly diatoms and greenalgae) was used to form marine oil snow (MOS). The aim was to gain new insights into the oil incorporation mechanisms into marine snow.
