TED: What's hidden under the Greenland ice sheet? | Kristin Poinar

The video explores the fascinating world of glaciology, focusing on the Greenland ice sheet. It discusses the use of radar and satellites to uncover hidden features and dynamics of the ice sheet, including the discovery of a glacier aquifer. The video highlights the importance of numeric models in predicting future sea level rise and the role of glaciologists in understanding these changes. The potential impact of the aquifer on ice flow and sea level rise is also examined.

What are the potential consequences of the ice sheet losing mass into the ocean?

Describe the process by which cracks in the ice sheet can lead to water reaching the ocean.

What challenges do scientists face in predicting future sea level rise?
