Tectonics and paleoceanography in the northern sector of the Antarctic Peninsula: Preliminary results of HESANT 1992/93 cruise with the B/O HESPERIDES
11 páginas, 7 figuras. [EN] The boundaries between the plates located in the northern sector of the Antarctic Peninsula were investigated during the B10 HESPERIDES HESANT 92/93 cruise using multichannel seismic profiles, magnetometry, and multibeam echo sounding. The investigation focused on the ana...
