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.

In 2012 the parent body, NERC, proposed merging the BAS with another NERC institute, National Oceanography Centre in Southampton. This proved controversial, and after the House of Commons Science and Technology Committee opposed the move the plan was dropped.The BAS operates five permanent research stations in the British Antarctic Territory:Of these Research Stations, only Rothera and Halley are usually manned throughout the year. Halley VI was closed for the March 2017 winter after relocation due to safety concerns when a previously inactive crack, "Chasm 1", in the Brunt Ice shelf began to expand in the direction of the base. The base was closed again in March 2018 with similar concerns. The remaining bases are manned only during the Antarctic summer.
