The British Antarctic Survey has around 420 staff of whom around 40 spend the austral winter in the Antarctic. The activities of the British Antarctic Survey are organised from the BAS UK Cambridge facilities at a site on the outskirts of the city of Cambridge. The original building, constructed in 1975, has been extended twice since then. It now provides offices, laboratories and workshops to support all the scientific and logistic activities in the Antarctic.
Specialised facilities for the scientific staff include laboratories for the physical and chemical analyses of biological, geological and ice specimens, molecular biology facilities, a scanning electron microscope, sample preparation and controlled environment rooms (including a cold aquarium and extensive freezer storage) as well as a library, archives, computing and mapping facilities.
