Snow height was measured by the Snow Depth Buoy 2014S12, an autonomous platform, drifting on Antarctic sea ice, deployed during POLARSTERN cruise PS82 (ANT-XXIX/9). The resulting time series describes the evolution of snow height as a function of place and time between 17 Jan 2014 and 02 Feb 2016 in sample intervals of 1 hour. The Snow Depth Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on first year ice. In addition to snow height, geographic position (GPS), barometric pressure, air temperature, and an internal ice temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy. The data set has been processed, including the removal of obvious inconsistencies (missing values). Records without any snow height may still be used for sea ice drift analyses.
