Polarimetric Radar Data and Ice Core Data Collected at Hammarryggen Ice Rise AUTHORS: Frank PATTYN, Sarah WAUTHY, Sainan SUN, Jean-Louis TISON, Veronica TSIBULSKAYA Laboratoire de Glaciologie Université libre de Bruxelles (ULB) Brussels, Belgium FUNDING: Project MASS2ANT (Belgian Science Policy Office - BELSPO) DATA FILES ACCOMPAGING PAPER BY REZA ERSHADI et al. (2023) Deciphering the Ice Dynamic History of a Promontory Ice Rise with Triple Junction: A Polarimetric Radar Approach Autonomous Phase Sensitive Radar (ApRES) measurements Hammaryggen Ice Rise FILES: Folders 2018p00 to 2018p14 + ApRESpos.csv Measurements by F. Pattyn and S. Sun Each folder contains the raw ApRES data sampled at the site. The 'Survey' files are single measurements with exactly the same antenna orientation and taken almost a year apart (exact date in the file name). The 'Survey' or 'DATA' files ending on HH, HV, VV, VH are measurements for each of the four antenna orientations for the polarimetric analysis. Each folder is a data point along a survey line perpendicular to the ice divide of the Hammaryggen ice rise, East Antarctica. The geographic positions of the data points are given in the table ApRESpos.csv. Eigen values of c-axes distribution for discrete samples from the Hammaryggen ice core FILE: HammeryggenIceFabric.xls Measurements by S. Wauthy, J.L. Tison and V. Tsibulskaya This table provides the eigen values of c-axes distribution for discrete samples from the Hammaryggen ice core (Wauthy et al., 2023). Data have been collected from discrete 8 cm vertical thin sections. The thin sections were obtained using standard techniques in glaciology (Langway, 1958) and analysed with an Automatic Fabric Analyzer (AFI, Wilson et al., 2003). Raw data from the AFI are at the pixel scale. To derive ice fabric data at the ice grain scale, the FAME software has been used (Hamme and Peternell, 2006). The software delineates grains using image analysis techniques and derives statistics for grain number, size and morphology and ice crystal orientation in space (c-axes). The software calculates eigen vectors and values for the c-axes distribution in each thin section. Column A of the table gives the top depth of each thin section analyzed, columns B to D give the eigen-values of the c-axes distribution used in this paper, to compare to modelled ones.
