Deployment of corer The photo shows how to deploy a corer to collect a sediment core sample from the sea bottom. The corer is kept fixed sideways on the deck, when it is not in use. Before its deployment, the corer should be first shifted laterally toward the sea at the side of the vessel, since it is too long to be put upright on the deck. Then, the corer can be rotated in an upright position above the sea surface. This needs a skilful operation of pulleys and winches.
