Through this demonstration and review of the attached research documents and the expedition PolarConnect event archive you will better be able to visualize how warming deep ocean currents undermine the ice sheets of Antarctica.
Objectives
To determine, through a demonstration and review of a scientific abstract, how warm water currents speed up ice sheet loss and sub-ice
This 1 hour webinar conducted by PolarTREC teacher Glenn Clark studying the Totten Glacier System in Antarctica. Glenn focuses on the shipboard science activities to understand the marine ecosystem and glacier systems of east Antarctica.
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
