Recovery of the elevator containing the biobox. Samples of tube worms were collected by Jason and put into a biobox. Instead of bringing the ROV to the surface, which takes about two hours, the samples were put into a box and the box into an elevator, which consists of several baskets and floats attached to a frame. The elevator is sunk, filled with materials destined for the surface, and a signal releases a weight so that the elevator rises to the surface. It is then recovered by the zodiac. The yellow balls are the floats at the top of the elevator.
