Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2018S64, deployed at the Barneo ice camp 2018

Snow height was measured by the Snow Depth Buoy 2018S64, an autonomous platform, drifting on Arctic sea ice. This buoy was deployed at the Barneo ice camp 2018. The resulting time series describes the evolution of snow height as a function of place and time between 21 April 2018 and 01 April 2019 in...

Description
Summary:Snow height was measured by the Snow Depth Buoy 2018S64, an autonomous platform, drifting on Arctic sea ice. This buoy was deployed at the Barneo ice camp 2018. The resulting time series describes the evolution of snow height as a function of place and time between 21 April 2018 and 01 April 2019 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 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.
