UPDATE June 2015: I have added the minutes and hours that have elapsed since the start of the video. This video was created from time lapse pictures taken at one minute interval in an ice cave, melted during fieldwork at the Svartisen subglacial laboratory. The camera was placed on the bedrock below 200 metres of ice. The video shows the cavity closing due to the pressure created by the overlying glacier ice. The frame moved because the ice pushed the construction on which was the camera.
