Kroner Lake Thermal Area

The Kroner Lake Thermal Area in Antarctica represents one of the most extreme and scientifically remarkable geothermal environments on earth, where volcanic heat from the active geothermal system underlying the Antarctic continent warms isolated pools and lake systems in one of the coldest, most remote, and most intensively studied scientific environments on the planet. The geothermal water in this Antarctic thermal zone maintains temperatures that support extraordinary microbial life in a setting otherwise characterised by the complete absence of macroscopic organisms, providing scientists studying extremophile biology with evidence of the conditions under which life might survive in extraterrestrial environments including the subsurface oceans of Europa and Enceladus. The combination of extreme polar environment, active geothermal system, extraordinary extremophile biology, and the remarkable scientific community of the Antarctic research stations that study these phenomena places Antarctic geothermal zones among the world's most scientifically significant thermal environments despite their complete inaccessibility to general visitors.
