Description
Summary:Spatial snow and ice thickness measurements from ice stations PS81/503, PS81/506 and PS81/517 from Research Vessel Polarstern in the Antarctic Weddell Sea in austral winter 2013 (cruise leg ANT-XXIX/6, AWECS campaign). Terrestrial laser scanning (TLS) was used to determine the snow surface height above sea level for an approximately 50x50m patch. The reference to sea level was obtained using registration targets drilled through the ice with a measured distance between the target and the water level in the drill holes. Magnaprobe measures snow depth (Sturm et al., 2018) and the GEM-2 instrument measures the combined snow and ice thickness (Hunkeler et al., 2016). Magnaprobe and GEM-2 was performed inside the laser scan field after all scans had been acquired. Additionally floe-scale walks were performed using Magnaprobe and GEM-2 to capture variability on a larger scale than the laser scan field. Further information can be found in Wever et al. (2021).
