Southernmost settlements
There are many research stations in Antarctica, both permanent and summer only. Many of the stations are staffed all year. McMurdo Station is the largest with an average population of 1200.
Halley Research Station
The British Antarctic Survey announced that it intended to move Halley VI to a new site in summer 2016-2017. A large crack had been propagating through the ice and threatened to cut the station off from the main body of the ice shelf, prompting the decision to move. The planned move would see the station shifted from its previous site and would be the first time the station had been moved since it became operational in 2012. Horizon, the long-running BBC documentary series, sent film-maker Natalie Hewit to Antarctica for three months to document the move.
