Scavenger Lander Assembly, Askøy, Norway.

Today at Solvik´s workshop the lander floats, the computer and camera were attached.

The lander sinks during deployment because it is negatively buoyant due to 12 x 17 kg steel weights. When we want the lander to return to the surface, to retrieve the images of the scavengers feeding on the jellyfalls, an acoustic signal is sent to the release units which causes a catch to open releasing the cables holding the weights.  The weights are then released, making the lander positively buoyant due to the floats.  The lander then rises to the sea surface where it can be returned to the ship.
