Lake Bonney

Since it was examined by the first British expedition to the continent in 1901 and then again in 1913, when it was officially given its name, Lake Bonney is perhaps one of the most well-known lakes in Antarctica. Thomas Goerge Bonney, a professor of geology in Britain, is honored by the name Lake Bonney. By a glacier under the lake, researchers found an ancient ecosystem in 2007. The lake's ecosystems are still being researched right now. Lake Bonney is one of the main lakes studied by the National Science Foundations, McMurdo Long Term Ecological Research site.

7 km long and up to 0.9 km broad, Lake Bonney is a sizable body of water. It is 57–60 meters above sea level. The 3.7–4.5 m thick ice that covers Lake Bonney is a result of the severe Antarctic environment. Since less than 5% of sunlight can penetrate the ice, the lake remains always gloomy or almost so. A little moat in the ice may only open during the summer. There is a severe phosphorus deficit, which leaves the lake water devoid of nutrients. Nevertheless, cyanobacteria, proteobacteria, algae, and ciliates are present in the lake's deeper regions.
