My PolarTREC expedition to the Dry Valleys of Antarctica was an experience of a lifetime. Notice I did not use the word “trip” of a lifetime. This was far more than a trip. It was an experience that is a life-changer. It has been a life-changer for myself, my students, my family, other educators, and other folks
This lesson was created by 2017 PolarTREC teacher Steve Kirsche who took part in the Dynamic Observations of the Microstructural Evolution of Firn expedition. The lesson is intended to introduce students to the concepts of isostasy and postglacial rebound through a demonstration and related instruction. Students will then see how postglacial rebound is an important factor when assessing the
This lesson is intended to introduce students to the concept of using ice core samples to learn about the past. Students will be “collecting” a sample from a model of ice. They will then evaluate the sample to see how the layers change as the depth changes.
Objectives
At the completion of this lesson, students will gain a greater
Lake El'gygytgyn (67.5º N, 172º E) is one of the best preserved large asteroid impact craters on earth. In the winter of 2009, I joined an international science team and traveled to the frozen arctic lake to drill and extract lake sediments to study climate change as well as sample the rocks that were changed when the crater
Lake El'gygytgyn (also called, Lake E) permafrost drilling started in mid-November of 2008. The ICDP (International Continental Drilling Program) is posting news reports and images to this blog several times each week. Check out early reports from Lake E.
IPY marks the beginning of a sustained effort to understand large-scale environmental change in Earth's polar regions, which have major societal and economic impacts, and to advance new scientific frontiers, from the molecular to the planetary scale. NASA brings a unique perspective to IPY, which will focus on five themes: 1) NASA explores scientific frontiers in Earth's polar regions.; 2)
