McMurdo Station
The McMurdo Station is a United States Antarctic research center on the south tip of Ross Island, which is in the New Zealand-claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo.
British Antarctic Survey
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.
