Snow on Antarctic sea ice has tremendous impacts on Albedo, light transmission and sea ice mass balance. Snow Buoys (Nicolaus et al., 2021) measure snow accumu- lation over time with four ultra sonic sensors. Here we present 14 Snow Buoys which were deployed in the Wed- dell Sea since 2013. These snow surface height measu- rements are coupled with the 1D SNOWPACK Sea ice versi- on model (Wever et al. 2020) in order to retreave snow pack processes, which are not detactable from the surface. Snow ice formation is a major process on Antarctic sea ice is, when the snow pack is flooded by sea water and refreezes. This changes the snow and sea ice mass balance. Here we present the effect on snow cover depth depending on season.
