Documentary about mysterious mineral-rich deposits in the form of nodules on the floor of the deep ocean, often in dense carpets that would be a very valuable source of nickel and manganese if the problems associated with recovering them could be resolved. The problems are in two categories: First, the difficulty of raising these nodules through several kilometers of water, and second, determining who has mineral rights outside any nation's territorial waters. The program covers these problems and also the scientific puzzle about how they are formed.
