This ice moves downwind as giant floes and vast floes in a matrix of smaller floes and brash ice (an accumula- tion of floating ice made of fragments <2 m across). This accounts for the areas with large floe streams in Figs. 10-1-10-5. This phenomenon shows up well in both Fig. 10-9 and 10-10, and was noted during the BESEX experiment by Ramseier et al. (1974), Gloerson et al. (1974), and Campbell et al. (1974). When locations of the leads and floes for both days are compared, it is seen that the floes have moved, and that the orientation of the leads remained consis- tent, approximately perpendicular to the wind.
