Abstract:
Snow height was measured by the Snow Depth Buoy 2015S19, an autonomous platform, installed on fast ice in the Atka Bay close to Neumayer III Base, Antarctic during POLARSTERN cruise PS89 (ANT-XXX/2). The resulting time series describes the evolution of snow depth as a function of place and time between 03 Jan 2015 and 15 Jul 2015 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. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and an internal ice temperature were measured. Negative values of snow depth 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 depth may still be used for sea ice drift analyses.
