Blue and turquoise colours indicate results based on the gap-filled MEaSUREs dataset (see methods). Orange colours indicate that results are from the PROMICE Sentinel-1 derived velocities. Black line is best linear fit through the MEaSUREs datasets (from the years 2005/2006, 2007/2008, 2008/2009, 2009/2010, 2012/2013, 2014/2015, 2015/2016 and 2016/2017), dashed black lines represent best linear fit if internal ice deformation temperatures are offset by ±5 °C. The shape of the points indicate origin of surface and bed topographies.
