In 1987, Slovakia bought part of the ocean bottom with the occurrence of mineral resources future - polymetallic nodules. The polymetallic
nodule is a geological term for naming natural features consisting of more than 40 metals and other chemical elements. These special services originated in the ocean
for two to three million years and nowadays, they are of main interest for countries whose mineral wealth is little or no available. Nodules contain about
30 % manganese, 1.2 % copper, 1.2 % nickel, 0.2 % cobalt, rare earth elements, etc. The existence of submarine nodules was found by the British ship HMS "Challenger"
by oceanographic research in 1872 - 1876. Research and the subsequent mining of nodules were particularly points of interest for Western countries as well as the
USSR. Rules for the use of mineral resources of the seabed beyond the limits of national jurisdiction were codified in the Convention on the Law of 1982, which
came into force on 16.11.1994, and in the Slovakia on 21.7.1996. The seabed is one of the international space next to the high seas, Antarctica, outer space and
celestial bodies, which are not subject to the sovereignty of any state authority
