• Resumen

  • The geomorphology and acoustic character of the continental shelf of Trinity Peninsula, NE Antarctic Peninsula, shows widespread evidences of glacial geological processes. The shelf is wide and deep, and is incised by seven major; u-shaped valleys of glacial origin, the larger ones developed on the W portion of the study area, and decreasing in length, width and depth towards the NE. Five distinct acoustic facies and distinct morpho-sedimentary provinces are identified along the shelf and neighbouring upper slope by means of high-resolution seismic profiles and multibeam bathymetry. These allow to deduce the recent sedimentary erosivedepositional processes on this sector of the Antarctic peninsula.
