- description: UAV (unmanned airborne vehicle) flight along a crack in the Brunt Ice Shelf, which appeared. This was detected by scientists in October 2016. Halley VI station (https://www.bas.ac.uk/polar-operations/sites-and-facilities/facility/halley/) is in the final stages of being relocated 23 km from its present site to put it upstream of a previously dormant ice chasm that began to show signs of growth in 2012. In October 2016, a second crack appeared some 17 km to the north of the research station. Since then glaciologists have monitored the growth of this crack using a network of GPS instruments that measure the deformation of the ice, together with European Space Agency satellite imagery, ground penetrating radar, and on-site drone footage, which show that the recent changes to the Brunt Ice Shelf have not been seen before. This second crack is shown in this video.
