Short summary
A sea ice drifting observatory in 2019 and 2020 provided a year of observations of Arctic snow and sea ice, though some data were interrupted, especially during summer melt onset. We developed a data–model fusion system to produce continuous, high-resolution time series of snow and sea ice parameters. On all three analyzed ice types, snow redistribution correlated with sea ice deformation, and level ice thickness was governed by the thinnest fraction of snow cover.
