Trapped Air

by Kay Helfricht, alpS Centre for Climate Change Adaptation Technologies, Innsbruck, Austria

Trapped air bubbles in the ice of an englacial conduit. These features evolve when the conduit is filled with meltwater of the glacier. Air bubbles are stored at the roof of the conduit. When the water in the conduit starts to refreeze, these bubbles are trapped.
