Lake Bonney is a saline lake located in the McMurdo Dry Valleys of Antarctica. It is known for its unique ecosystem, which includes microbial life that thrives in its salty waters. The lake is divided into two main basins, with the eastern basin being more saline than the western one. The lake is also significant for scientific research, particularly in the fields of limnology and climatology. Studies conducted at Lake Bonney help scientists understand the effects of extreme environments on biological processes and contribute to knowledge about climate change in polar regions.
