New Lakes Discovered Under Antarctic Ice with NASA's ICESat-2

The video explores the discovery and dynamics of meltwater lakes beneath the Antarctic ice sheet. Initially thought to be isolated, these lakes are interconnected by vast hydrologic systems. NASA's ICE and ICESAT 2 satellites have revealed that these lakes actively fill and drain, affecting the ice sheet's surface. Recent findings show new lakes experiencing drainage, providing insights into how lake boundaries change over time. Understanding these processes is crucial for predicting the Antarctic ice sheet's response to climate change and its impact on global sea levels and ocean currents.

What does the draining of lakes under the ice sheet indicate about the ice surface?

Why is understanding the flow of water under the Antarctic ice sheet important for predicting climate change effects?
