Figure 6: Sea ice volume variability in the Vistula Lagoon (a, b) and near Kaskinen (c). While in Kaskinen sea ice concentration and sea 
ice thickness was sampled frequently, in the Vistula Lagoon data occur only sporadically in the data set. This is why the observed increase 
in ASIV in the Vistula Lagoon is unrealistic.
