Description: This dataset contains airborne radar data acquired using the AWI EMR system (Nixdorf et al., 1999) during the Arctic season of 2015. The profiles extend western DML over the Maud Belt and Ekström Ice Shelf to investigate the geodynamic evolution of East Antarctica, the Forster magnetic anomaly (GEA-V-FMA). The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.

Comment: Project PI: Graeme Eagles (AWI) Contact persons for AWI Radio-echo sounding data: Daniel Steinhage (daniel.steinhage@awi.de), Veit Helm (veit.helm@awi.de), Olaf Eisen (olaf.eisen@awi.de) -- The netCDF files contain the following variables: altitude: Platform altitude (WGS84) in meters bed_elevation: Bed elevation for each trace (without applying a firn correction and permitivity of ice: 3.15) in meters bed_pick: picked Bed location for each trace, expressed as twt in seconds from time zero data: Radar data (Values in dBm after DC conversion) data_agc: Scaled radar data using automatic gain control (AGC) distance: Along-track distance in meters ice_thickness: Ice thickness for each trace (without applying a firn correction and permitivity of ice: 3.15) in meters lat: Latitude in decimal degrees (WGS84) lon: Longitude in decimal degrees (WGS84) range: Range between sensor and surface in meters spacing: Along-track trace to trace spacing in meters surface: Surface elevation derived from radar (WGS84) in meters surface_pick: Picked surface reflection in two-way travel time in seconds time: Seconds of day twt: Two-way travel time (twt) in seconds -- The KML files are in EPSG:4326, and the quicklook images show the AGC product of the radargram.
