The researchers on the project will continue to map the
ocean floor along the Mid-Atlantic Ridge for potential mineral
deposits, using images from echo sounders and remotely operated submersible vessels.
Most of the
deposits, some small and some large, are buried in or below permafrost and sediments in the
ocean bottom
along continental margins — where shallow offshore waters slope down toward the deeper
ocean floor.
Slowly, the carbonate rocks will be eroded and carried by rivers to the
