Scientists Bury GPS in Antarctic Ice to Measure Effects of Tides

Christine Doug discusses her research on Antarctic and Greenland ice sheets, focusing on their contribution to sea level rise. She details an expedition to Terra Nova Bay, supported by the Korea Polar Research Institute, to study the effects of ocean tides on ice shelf motion. The journey to the ice shelf is described as spectacular, with a unique silence experienced upon arrival. The video concludes with a discussion on the dynamics of ice sheets and concerns about their potential break-up, which could lead to accelerated ice flow into the ocean.

Explain how the ice shelves act as a barrier to ice flow.

What are the potential consequences of ice shelves breaking off?
