MARVEL accommodates up to four hi-cube 20 ft containers that serve as research laboratories for various scientific disciplines.
The principal methods to access the environment above and under the ice cover are drones and the moonpool. Aerial and underwater drones are used for sampling and observations and to set out instruments for acoustical recordings. The moonpool offers access from the sheltered interior of the vessel to the underwater environment and the underside of the sea-ice. Scientists can lower a wide variety of sampling, measuring and observation instruments through the moonpool, as well as scuba divers and submersible robotics.
