CORING RESPIROMETER – A free vehicle lander equipped with 4 megacore tubes that are pushed into the sediments by a drive motor after the vehicle lands on the seafloor. Each tube is equipped with an oxygen optode and water mixing pump to measure sediment community oxygen consumption in each core. Each core is trapped by a standard megacore core catching device and returned to the surface with the lander. The instrument also includes an oxygen sensor for the ambient bottom water.

CTD – Conventional CTD rosette was used to take water samples to 5000m depth at several stations.

ABYSSAL LANDER – A free vehicle lander equipped with a still image camera and baited to attract scavengers. Images were taken once every minute. It is rated to 6000m.

HADAL LANDER – A free vehicle lander equipped with a digital video camera and baited to attract scavengers. One minute of video was recorded every 2.5 or every 5 minutes. It is rated to 11000m.

FISH TRAP – A large mesh trap with two smaller PVC tube shaped amphipod traps inside that were baited to capture megafauna. It was deployed as a free vehicle lander.

WEE TRAP – Another baited trap but smaller in size than the fish trap.
