AbstractSubmarine mass-movement is a characteristic process on high latitude margins that results from the interplay of repeated advance and retreat of grounded ice, oceanographic, glacigenic and tectonic processes. In the particular case of Antarctic continental margins, there are some important examples, some of them well-documented like the case of the GEBRA Debris Valley, located on the lower continental slope of the Antarctic Peninsula in the Central Bransfield Basin-CBB. It has been defined as a Quaternary Debris Valley formed as a result of repeated large-scale mass transport processes. This feature is included in the so-called GEBRA-MAGIA sedimentary instability complex formed by the GEBRA itself and a cluster of mass wasting features that makes up the MAGIA complex. New data from MAGIA are presented in this work with the aim to characterize its morphosedimentary features and the disintegrative dynamic affecting the area
