The dataset consists of raw data from six autonomous phase-sensitive radar (ApRES) measurements. The ApRES with two bow-tie antennas were operated at a basal melt channel of the southern Filchner Ice Shelf, Antarctica near the Support Force Glacier. Five short-period ApRES were located at a cross-section of the channel, located east outside the channel (ApRES_oe), at the eastern steepest flank of the surface depression (ApRES_se), within the channel at the lowest surface depression (ApRES_low), at the western steepest flank (ApRES_sw) and west outside the channel (ApRES_we). All four ApRES operated for 9 to 13 days with a measuring interval of 15 minutes. The long-period ApRES (ApRES_oe_long) operated east outside the channel for 361 days with a measuring interval of 2 hours. The short-period ApRES were operated parallel to GPS stations (see doi:10.1594/PANGAEA.932441). These Lagrangian measurements allow the estimation of basal melt rates based on estimated vertical displacements of englacial and basal ... : Data were measured in the field by Daniel Steinhage. This dataset has been planned by Angelika Humbert as part of FISP. If you have questions, please contact Ole Zeising ([e-mail]) or co-authors. ...
