Snow height on sea ice, meteorological conditions and drift of sea ice from autonomous measurements from buoy 2019S91, deployed during RV Araon 2019

Snow height was measured by the Snow Buoy 2019S91, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during RV Araon 2019. The resulting time series describes the evolution of snow height as a function of place and time between 13 August 2019 and 25 August 2019 in sample inte...

Description
Summary:Snow height was measured by the Snow Buoy 2019S91, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during RV Araon 2019. The resulting time series describes the evolution of snow height as a function of place and time between 13 August 2019 and 25 August 2019 in sample intervals of 1 hour. The Snow Buoy consists of four independent acoustic range finder measurements representing the area (approx. 10 m**2) around the buoy. In addition to snow height, geographic position (GPS), barometric pressure, air temperature, and surface 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.
