Operation IceBridge is an aerial survey that measures both land and sea ice in the Arctic and the Antarctic. There are many reasons to monitor the polar regions. The cryosphere is essential in helping to maintain global climate. One important reason is to investigate sea level rise. Land ice can cause sea levels to rise, when it melts, by adding
In this one hour presentation, PolarTREC teacher John Wood explains the scientific work in the Carbon Balance in Warming and Drying Tundra expedition from Healy, Alaska.
This one hour presentation is part of the C-ISE Physical Science professional development course. Elizabeth Webb in Healy, Alaska explains the carbon balance in warming and drying tundra.
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.
