Lakes in Antarctica
222 Views
Scientists are not complacent. We still have a lot to learn about the water cycle. The discovery of glacial lakes under the ice in Antarctica actively transporting water between reservoirs was a surprise. These lakes can be up to 3km beneath the ice sheets. The pressure of the ice above helps to melt the ice, forming lakes. Helen Amanda Fricker is mapping the lakes and monitoring the flow of water and ice. Scientists are hoping to drill into these lakes and even look for microbial life.
