Description
Halley is on a floating ice shelf which moves roughly 500m per year. In winter there is darkness for 105 days. Supplies are landed by ship onto the ice shelf and then towed on sledges to Halley, some 12 km distant from the ice edge. Ozone has been measured at Halley since 1956. The present station (the fifth near this location) contains a mix of building technologies. Three buildings are located on platforms on steel legs, which are raised annually to keep them clear of the accumulated snowfall. The station operates throughout the year with a maximum population of 65 in the summer and an average of 15 over winter.
