Lake Ontario-sized water body lies hidden under 4 km of Antarctic ice
Scientists have identified a massive, lake-sized body of water hidden beneath four kilometers of Antarctic ice. Known as Lake Vostok, it remains liquid due to geothermal heat and extreme pressure, offering a unique environment for study.
Why it matters
The discovery provides insights into subglacial environments and the potential for life in extreme conditions, expanding our understanding of Earth's geography.
Antarctica is the coldest continent on Earth, featuring a deadly combination of extreme temperatures, high elevation and ice-covered terrain. The Russian Vostok Station here averages minus 55°C and on July 21, 1983, it recorded the lowest reliably measured air temperature on Earth, −89.2°C.Yet sealed beneath the white ice sheets of the region is a hidden ocean-sized lake that challenges the human understanding of life's limits and nature's magic. About four kilometres beneath the station is not frozen bedrock but one of the largest lakes on the planet.Nature's anomalyLake Vostok is roughly 230 to 250 kilometres long and about 50 kilometres across at its widest point. Estimates of its exact area and depth vary as radar coverage and models improve, but its scale is comparable to Lake Ontario.
