Snow height on sea ice, meteorological conditions and drift of sea ice from autonomous measurements from buoy 2018S82, deployed during RV Araon 2018
Snow height was measured by the Snow Buoy 2018S82, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during RV Araon 2018. The resulting time series describes the evolution of snow height as a function of place and time between 19 August 2018 and 24 August 2019 in sample inte...
