Video of the vertical evolution of a horizontal cross section (3.6 x 7.2 mm) of the sea ice brine pore space over a vertical distance of 5.4 mm. The crossover from low to high porosity is accompanied by the close-off of pores when the necks reach a critical thickness slightly less than 0.1 mm (see the paper for details). Note that the video shows only a part of the cross section (typically 20 x 20 mm) analysed in this study, in order to emphasize the necking in a low porosity region.
