El límite Cuenca Powell/Mar de Weddell. Estructura y relación con la fragmentación Cenozoica de la Península Antàrtica
Late Paleogene to Neogene continental fragmentation of the Northern Antarctic Peninsula caused the development of small oceanic-floored basins such as Powell Basin. On the basis of MCS profiles and swath bathymetry collected during Hesant 92/93 cruise, a tectonic map of the transition zone between P...
