Velocity maps were derived, for regions of Larsen C ice shelf, from satellite imagery spanning the period November 2017 to April 2019. This period was selected to monitor any change in the velocity field of Larsen C, in the months following the calving of iceberg A68 from the front of the ice shelf. The archive contains two sets of maps. The first are derived from Sentinel-1 satellite data, and span the complete ice shelf for the full 18-month epoch. The second are derived from TerraSAR-X data, and show high-resolution velocity trends between 2017 and 2018, covering the frontal region of Larsen C ice shelf. The maps were produced by Professor Adrian Luckman, Swansea University. The data is part of the NERC RACE project, NE/R012334/1.
Velocity and along-flow stress states were modelled for Larsen C ice shelf, before and after the calving of iceberg A68 in July 2017. The archive contains two sets of model outputs: i) flow velocity before and after calving, and the difference between these periods, and ii) along-flow stress before and calving, and the difference between these periods. The models are produced with the BISICLES ice sheet model. Additionally to high-resolution geo-referenced model outputs, a low-resolution image of each is provided for reference. The maps were produced by Dr Stephen Cornford, Swansea University. The data is part of the NERC RACE project, NE/R012334/1.
