Manganese nodules were first discovered on the ocean floor 160
miles south-west of the Canary Islands on February 18, 1803, during
the first complex oceano logical cruise of the Challenger. They
surprised researchers by their unusual shape and also by their
unusual chemical composition; nevertheless for many years after
wards, they were considered merely as one of Nature's exotic marine
tricks. After the Secpnd World War, a comprehensive investigation
of the World Ocean started, and new data were obtained on a wide
distribution of manganese nodules and their polymetallic
composition, that made scientists consider nodules as one of the
major characteristics of the deep oceanic zone. Recently, meaning
since the 1960's, nodules have been recognized as a potential ore
source, investigation of which is stimulated by the progressive
depletion of land-based mineral resources. Several generations of
scientists from various countries have contributed to the problem
of exploration of manganese nodules on the ocean floor. Though the
problem has been posed, it has not been solved yet because it
required, in its turn, a scrutiny of some fundamental aspects such
as composition, nature, accretion r'ate of nodules and retrieval of
nodule fields. These problems have been discussed in thousands of
papers and larger publications; see, in particulare, Mero, 1965;
Horn, 1972; Morgenstein, 1973; Bezrukov, 1976; Glasby, 1977;
Bischoff and Piper, 1979; Lalou, 1979; Manganese nodules, 1979;
Varentsov, 1980; Cronan, 1980; Manganese nodules . . ., 1984,
1986."
