Dataset from: Tuckett, P.A., Ely, J.C., Sole, A.J., Livingstone, S.J., Davison, B.J., van Wessem, J.M., Howard, J. 2019. Rapid accelerations of Antarctic Peninsula outlet glaciers driven by surface melt. Nature Communications. In Prep. AntP_speed_geotiffs - geotiffs of ice flow velocity of 5 marine terminating outlet glaciers on the Antarctic Peninsula (Crane, Jorum, Hektoria, Drygalski and Cayley). Ice velocity estimates were derived from feature and speckle tracking of Sentinel 1a and 1b Interferometric Wide Swath mode Single-Look Complex Synthetic Aperture Radar amplitude images. These data cover two swathes and include 184 six- or twelve-day repeat image pairs between October 2016 and mid-April 2018. The dates of the two images used to derive velocity are included in the file name. Front_positions - ice front positions for the same 5 marine terminating glaciers, mapped using the tool GEEDiT in Google Earth Engine. This analysis used cloud free Landsat 8 and Sentinel 1 and 2 imagery.
