Ice shelves are the gatekeepers of Antarctica as t hey\nbuttress the contribution of grounded ice to sea level rise. Although several processes have been identified that are key for future ice shelf instability and retreat\, assessing how much\, how fast ice shelf instabil ity will contribute\nto future sea level rise remains a major uncertainty as many of the processes (e.g. hydrofracturing\, basal melting\, damage fe edbacks) are not well understood or quantified. In this presentation\, Ste f Lhermitte will discuss the role of satellite remote sensing and modellin g in assessing these processes by showing examples of Pine Island Glacier and Thwaites Glacier in the Amundsen Sea Embayment and other outlet glacie rs in Antarctica with large consequences for global sea level.\n LOCATION:https://researchseminars.org/talk/BASIDP/2/ END:VEVENT END:VCALENDAR
