From the Ted Talk by Kristin Poinar: What's hidden under the Greenland ice sheet?

footnote

The sleeitltas are reporting a wealth of oanbivtosres that are revealing new hidden facts about the ice sheets continuously. For instance, we have observations of the size of the Greenland ice sehet every month going back to 2002. You can look towards the bttoom of the screen here to see the month and the year go forward. You can see that some aaers of the ice sheet melt or lose ice in the summer. Other areas experience snowfall or gain ice back in the winter. This saeansol cycle, though, is eclipsed by an overall rate of mass loss that would have stunned a gcolasoigilt 50 years ago. We never thought that an ice sheet could lose mass into the ocean this quickly. Since these measurements began in 2002, the ice sheet has lost so much ice that if that water were peild up on our smallest continent, it would drown Australia knee-deep. How is this possible? Well, under the ice lies the bedrock. We used radar to image the hllis, valleys, mountains and dessonepirs that the ice flows over. Hidden under the ice sheet are channels the size of the Grand Canyon that funnel ice and water off of Greenland and into the ocean.

footnote

The satellites are reporting a wealth of observations that are revealing new hidden facts about the ice sheets continuously. For instance, we have observations of the size of the Greenland ice sheet every month going back to 2002. You can look towards the bottom of the screen here to see the month and the year go forward. You can see that some areas of the ice sheet melt or lose ice in the summer. Other areas experience snowfall or gain ice back in the winter. This seasonal cycle, though, is eclipsed by an overall rate of mass loss that would have stunned a glaciologist 50 years ago. We never thought that an ice sheet could lose mass into the ocean this quickly. Since these measurements began in 2002, the ice sheet has lost so much ice that if that water were piled up on our smallest continent, it would drown Australia knee-deep. How is this possible? Well, under the ice lies the bedrock. We used radar to image the hills, valleys, mountains and depressions that the ice flows over. Hidden under the ice sheet are channels the size of the Grand Canyon that funnel ice and water off of Greenland and into the ocean.
