Roller Tank Experiment for the component-specific Investigation of Oil Incorporation into Marine Oil Snow with a Phytoplankton Culture (Nodularia) (t = 24 hours)

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 cyanobacterium culture (Nodularia) was used to form marine oil snow (MOS). The aim was to gain new insights into the oil incorporation mechanisms into marine snow.

本滚动槽实验探究了不同油类化合物（正构烷烃（n-alkanes）与多环芳烃（polyaromatic hydrocarbons））在沉降型海洋油雪（marine oil snow）、周围海水中的未聚集颗粒以及溶解态水相之间的分配行为。此外，本研究还考察了消油剂科里散（Corexit）对上述过程的影响。本次实验以节球藻（Nodularia）蓝细菌培养物制备得到海洋油雪（MOS），旨在深入阐明油类向海洋雪中的结合机制，获取全新的科学认知。
