New geological interpretation of multi-channel seismic profiles from the Pacific Margin of the Antarctic Peninsula
Abstract The Polish Geophysical Expedition to West Antarctica in 1979–1980 was carried out by the Institute of Geophysics, Polish Academy of Sciences. Beside deep seismic soundings, 12 multi-channel seismic profiles, with a total length of ca 1000 km have been recorded north and east of the South Sh...
