Ground Penetrating Radar (GPR):
Seeing Below the Surface While Keeping Scientists Safe
Overview
Ground Penetrating Radar (GPR) is a valuable technology that utilizes waves of low frequency electromagnetic radiation to help polar scientists understand what is beneath their feet! Using real field data from the Icelandic glacier Múlajökull, along with a small selection of short videos and web-based resources
One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
Students are asked to predict what will happen to styrofoam objects lowered down to the bottom of the Bering Sea. Students make the appropriate calculations related to the actual experiment which took place on Maggie Prevenas' PolarTREC expedition.
Objective
Students will make hypotheses and calculations regarding deep sea experiments that took place in the Bering Sea on
