L'empremta del clima a l'Antàrtida: dinàmica glacial i extensió del gel durant el darrer màxim glacial
10 pages, 8 figures, 1 table Multibeam swath bathymetric and TOPAS sub-bottom profiler data collected from the Antarctic Peninsula margin during the last decade have allowed to obtain a better understanding of ice extent and dynamics during the Last Glacial Maximum. These data show that the continen...
