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.

What is the primary focus of Christine Doug's research?

• Researching sub-Antarctic Lake development using numerical models

• Exploring the biodiversity of Antarctic marine life

• Developing new technologies for ice-breaking ships

• Studying the impact of climate change on polar bears

Which research station did the team visit for their fieldwork?

• Russian Vostok Station

• British Antarctic Survey Station

• New South Korean research station, John Bogo

• United States McMurdo base

What unique experience did the team have upon arriving at the Tiltmeter site?

• Hearing the loud noise of ice cracking

• Seeing a rare solar eclipse

• Encountering a polar bear

• Experiencing complete silence

What role do ice shelves play in the movement of ice sheets?

• They have no impact on ice movement

• They act as barriers, slowing down the ice flow

• They increase the melting rate of ice sheets

• They accelerate the flow of ice into the ocean

What is a major concern regarding the ice shelves around Antarctica?

• They might break up, leading to faster ice flow

• They are causing earthquakes

• They are growing too rapidly

• They are blocking shipping routes
