· Oil–mineral aggregate preparation OMAs were prepared by measuring 125 ml of unfiltered seawater (taken from a depth of 5 m in Bedford Basin, Nova Scotia) into a 250-ml Erlenmeyer flask. Mineral fines (<5 μm) were added as 200 μl of a concentrated suspension (60 mg ml −1 in distilled water) and gently mixed to suspend the sediment.
