ICEBERG-SCATTERED COARSE-GRAINED MATERIAL IN THE NORTH-ATLANTIC AND ON THE KING TROUGH BOTTOM (OBSERVATIONS FROM MIR SUBMERSIBLES)

The observations from MIR deep-water submersibles, drag sampling, deep -sea drilling and other data indicate a wide occurrence of glacial (er ratic) coarse-grained rock material on the North Atlantic bottom the c omposition of which differs considerably from the composition of the o cean basement rocks but which is still often thought to be on outcropp ing material. The paper generalizes the new data on the erratic materi al which was collected in the 19th cruise of the R/V ''Academic Mstisl av Keldysh'' and in marine expeditions of other vessels. Data are pres ented on the quantitative distribution, composition, provinces and sca ttering of erratic material from its sources by glaciers and icebergs.
