transport people and equipment over snow and ice covered regions. Smaller snowmobiles are also used for transport across snow and ice-covered areas as well. “Ivan the Terra Bus” and the large Kress are used to transport large numbers of people to and from the airfields over the ice roads of McMurdo Station. Passenger vans with wide tires are also used to transport people around McMurdo Station and Amundsen-Scott South Pole station as well. McMurdo Station also has a small fleet of pickup trucks. Power/water/wastewater Each station uses diesel fuel to generate electricity. At McMurdo Station, wind turbines installed by Antarctic New Zealand in 2010 supply about a third of the station's electricity in a cooperative agreement with ANZ. Field camps have been increasingly using solar power, taking advantage of the 24 hours of daylight during the Antarctic summer. Reverse osmosis is used to desalinate sea water for drinking at McMurdo and Palmer stations. Potable water at Amundsen-Scott South Pole Station, which sits atop an ice sheet nearly three kilometers (two miles) thick, is produced by melting ice. Wastewater is treated by the base wastewater plant using the activated sludge process.The effluent is sterilized using ultra violet light and discharged back into McMurdo Sound. Waste sludge is dried by being processed with a belt filter press and then boxed up for shipment back to the United States for incineration. Food Each station has its own kitchen and cafeteria. Food is provided free-of-charge to program participants and official visitors. The cafeterias serve breakfast, lunch, dinners, and a midnight meal for the night shift. Each station has a range of rotating entrees. Fresh fruit and vegetables, known colloquially as “freshies,” are popular items, but because of their short shelf life are not always available. Large field camps often have their own chef that cooks large group meals from shelf-stable supplies sent out at the beginning of their field season. At smaller field camps, cooking duties are often shared with other responsibilities amongst camp staff or researchers. Current Developments AIMS The Antarctic Infrastructure Modernization for Science (AIMS) is a ten-year construction project to upgrade and update McMurdo Station's infrastructure. Starting in 2021, the project will build about 370,000 square feet of new facilities, while razing several of the station's aging structures.
