This ecosystem survives by transforming sulfur and iron compounds for growth. The work is seen as a stage in developing an autonomous submersible robot that could explore the ocean on Jupiter's moon Europa. Lake Bonney is fed by a number of meltwater streams: Lake Bonney (Antarctica) Lake Bonney ( ) is a saline lake with permanent ice cover at the western end of Taylor Valley in the McMurdo Dry Valleys of Victoria Land, Antarctica.
