Antarctica
Each year, scientists from 28 different nations conduct experiments not reproducible in any other place in the world. In the summer more than 4,000 scientists operate research stations; this number decreases to just over 1,000 in the winter. McMurdo Station, which is the largest research station in Antarctica, is capable of housing more than 1,000 scientists, visitors, and tourists.
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.
