Glacier and Ground Penetrating Radar Fact Finding

Overview

Ground penetrating radar is an important tool for studying glacier dynamics. Glacier scientists use GPR images to analyze attributes of glaciers. The following research activity will familiarize students with the basics of the different types of glaciers and their dynamics along with ground penetrating radar and its use in glacier studies.

Goals/Objectives

Students will know the different types of glaciers, their attributes and flow dynamics. Students will know the basics of ground penetrating applications for below ground surface analysis. Students will complete ground penetrating radar and glacier research and prepare a sharable presentation using the iOS App “Explain Everything” or other presentation software.

Procedure

Research Parameters relative to the goal are listed below:

1. Find ten “oh wow” facts about glaciers. Student voice and choice applies here, but teacher guidance is expected. Possible web based information can be found at:

   • National Snow and Ice Data Center (NSIDC): All about Glaciers
   • NSIDC Further Reading
   • NOVA Online: Anatomy of a Glacier
   • Extreme Ice Survey: Types of Glaciers

2. Research, list, and describe the attributes of the different types of glaciers and locate photos of those types (see web sites above).

3. Find diagrams of how glaciers move (see web sites above).
4. Find five facts about ground penetrating radar.
5. Find information, diagrams and images of Ground Penetrating Radar pertaining to its use in glacier studies.
6. A Google Image search using “studying glaciers with ground penetrating radar” will produce many images that are useable for research and helping to gain a basic understanding of GPR.

7. There are many technical papers available on-line for ground penetrating radar used in glacier studies, so anyone using the suggestions. here will need to be their own discerning user of the internet, but a few links are listed below that may offer some content support and suggestions.

   • Research Paper: Estimation of glacier ice thickness using Ground Penetrating Radar in the Himalayan region
   • Research Paper: Ice volume changes (1936-1990-2007) and ground-penetrating radar studies of Ariebreen, Hornsund, Spitsbergen
   • Research Paper by PolarTREC Research Team Member Seth Campbell: Melt regimes, stratigraphy, flow dynamics and glaciochemistry of
     three glaciers in the Alaska Range

8. Complete “Explain Everything” or other application based presentation following presentation protocols (citations required) developed by classroom teacher or other education professional.
