During deep sea mining of polymetallic nodules, a crawler collects nodules by suction head. In the process, sediment is being pumped in together with the nodules. The watersediment mixture is released via an exhaust system, leading to a sedimentladen density current. The mixing of the density current plays an important role in the dispersion of sediment into larger turbidity plumes.
