Sediments samples dedicated to hydrocarbon analyses recovered from 8 drilling sites from up to 427 meter below seafloor. The samples (~40ml of sample) were aliquoted into two 50 ml Falcon tubes and was centrifuged at 3000 rpm for 15 minutes to separate porewater from the sediment.
After centrifuge the porewater was filtered through sterile syringe cellulose 0.45μm filters. 20 ml the porewater was collected into 20 ml serum vials for saturated hydrocarbons, polycyclic aromatic hydrocarbons (PAH) and alkane analysis and stored at 4oC.
The sediment cake from each horizon was kept and stored at 4oC for hydrocarbons, polycyclic aromatic hydrocarbons (PAH) and alkane analysis.
