Survey equipment

We have continued surveying North of Celtic Deep rMCZ using a range of scientific equipment. The Hamon grab sampler is lowered from the side of the ship using a winch and when it reaches the seabed it scoops up a sample of sediment which is then brought back to the deck. Today there were strong currents which meant that the Hamon grab often failed to collect a sample so we had to deploy it several times. The camera sledge and drop camera are towed behind the ship to collect video images while the ship moves along slowly.
