Please note that the Gravity Corer can only be operated upon request. Request operations with the Gravity Corer to AWI-Geology and AWI-Logistics in sufficient time prior to the cruise. Operations of the system require experienced scientific staff on board. The system is not operated by the ship's crew.

The gravity corer allows researchers to sample and study sediment layers at the bottom of oceans.The system is lowered to the sea floor and penetrates by its own weight into the sediments. When being pulled out of the sediments the core catcher closes and secures the sediment column inside the tubes. On deck the core catcher is removed, the plastic liners pulled out the barrels and cut into 1 m sections.
