GZWs are thought to form by deposition of subglacial till at temporarily stable, grounded ice-sheet marine termini between successive episodic retreats (Batchelor & Dowdeswell, 2015). Sub-bottom profiles show that the present-day morphology of Kveithola Trough is largely inherited from the palaeo-seafloor topography of the GZWs, which is now draped by a deglacial to early Holocene glacimarine sediment about 15 m thick. The ice stream that produced such subglacial morphology was flowing from east to west towards the shelf edge in Kveithola Trough during the Last Glacial Maximum (LGM). Its rapid retreat was probably associated with progressive lift-off, and successive rapid melting of grounded ice, induced by eustatic sea-level rise Peer Reviewed 2018-10-24T06:59:31Z 2018-10-24T06:59:31Z 2016-10-11 2018-10-24T06:59:31Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 ARCA PROJECT : ARctic: present Climatic change and pAst extreme events : Final Conference (2016) http://hdl.handle.net/10261/171443 http://www.arcaproject.it/index.php/en/results Sí open
