Vacuum Sampling

To sample animals in Lost City, we have constructed samplers for this cruise that use hydraulic suction to essentially vacuum animals from the seafloor. Much like using a vacuum cleaner in your living room, the pilot grabs the end of a retractable hose and positions the open end on the surface of a Lost City spire. The hydraulic pump is turned on and the suction begins. Pieces of carbonate and the small animals living on them get sucked into a four-liter chamber where the animals are stored until they reach the surface and taken off the vehicle for sorting.
