Extending the record of Antarctic ice shelf thickness change, from 1992 to 2017
Over the past two decades, Antarctic ice shelves have retreated, thinned and suffered catastrophic collapse. In this study we extended the 25-year long record of ice shelf thickness change in Antarctica, from 2010 to 2017. In the Amundsen Sea Sector where widespread ice shelf thinning dominates the...

Over the past two decades, Antarctic ice shelves have retreated, thinned and suffered catastrophic collapse.
