Entry for:180 Seconds of Discovery
1. What is the title of your video?
Past Ice \ Future Ice
2. Please provide a brief summary of the subject of your video!
Follow along on a journey to David Glacier, Antarctica. I share a unique discovery regarding the past behaviour of this glacier. The discovery, a rapid thinning event right at the end of Earth's last ice age, is made through careful collection of glacial erratics in the field and laboratory analysis of a rare element produced by high energy particles from deep space. This discovery frames modern ice changes in a historical context and informs predictions of the future Antarctic Ice Sheet and global sea level. In this way, past ice connects us to future ice.
