Scientists search for life in Antarctica's subglacial lakes

The video discusses lakes isolated from the atmosphere for millions of years, with over 300 identified. It highlights international efforts to drill into these lakes, including projects by Russia, the UK, and the USA. The drilling uses hot water drills at high pressures, and scientists have a limited time to collect samples before the borehole closes. The focus is on understanding the lakes' water and sediment samples.

How many lakes have been identified that are cut off from the atmosphere?

What is the temperature and pressure of the water used in the hot water drills?
