| Abstract |
During 1976-1990, ca 30,000 km of echosounding profiles were carried out and ca 7000 km of shallow seismic lines, 6051 samples of surface bottom deposits and 827 cores were taken. Also, 23 boreholes were made. Standard investigations in the laboratory were done including: 8850 analyses of grain size distributions, ca 3570 content of heavy minerals and ca 2150 composition of heavy minerals. Also, 14C, TL, pollen and diatomological analyses were carried out. The results of cruises and laboratory work are presented on 12 sheets of maps, which contain: the map of bottom sediments (scale 1:200,000), geological cross-sections, geological profiles, and maps (scale 1:500,000) of geomorphology, lithodynamics, sediments 1m below the bottom surface, and mineral resources (legends are in Polish and English). There is also an explanatory booklet for each sheet of the map (in Polish only). The results of cruises and laboratory work are also stored in a computer database (Fox-Pro). Only echograms and shallow seismic records are in hard copies.
