Demographics of Antarctica
Antarctica has few permanent residents, and contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. The largest station, McMurdo Station, has a summer population of about 1,000 people and a winter population of about 200. Approximately 29 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
Science and technology in China
The Chinese Arctic and Antarctic Administration (CAA) organizes China's scientific programme for both the Arctic and Antarctic. Polar research by China, in particular in Antarctica, has been growing rapidly. China now has three Antarctic research stations and one in the Arctic on the Norwegian island of Svalbard.
