Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2020S55, deployed during Antarctic Fast Ice Network 2020 (AFIN 2020)
Snow height was measured by the Snow Buoy 2020S55, an autonomous platform, installed in the Atka Bay, Antarctic during Antarctic Fast Ice Network 2020 (AFIN 2020). The resulting time series describes the evolution of snow height as a function of place and time between 30 Jul 2020 and 16 Jul 2021 in...

Snow height was measured by the Snow Buoy 2020S55, an autonomous platform, installed in the Atka Bay, Antarctic during Antarctic Fast Ice Network 2020 (AFIN 2020). The resulting time series describes the evolution of snow height as a function of place and time between 30 Jul 2020 and 16 Jul 2021 in sample intervals of 1 hour. The Snow Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on fast 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.
