This activity was prepared by David Walker (LASA High School) and Rose Cory (University of Michigan), based on work conducted during summer 2019 at Toolik Field Station in Alaska. The purpose is to expose students to photooxidation, one of the main pathways by which organic molecules in Arctic streams are oxidized into carbon dioxide. Different teas will be used
The work of professor Bryon Crump, graduate student Natasha Christman, and PolarTREC teacher David Walker is highlighted in the weekly newsletter of the Oregon State University College of Earth, Ocean, and Atmospheric Sciences (On the Horizon).
This article describes PolarTREC teacher Nick LaFave's upcoming expedition to Toolik Lake, Alaska where he will be studying wolf spider populations with Duke University researcher, Amanda Koltz.
View sequential still images of thermokarst (thawed permafrost) at Horn Lake in northern Alaska during the summer of 2010. The video was made by researchers studying the responses of Arctic landscapes to permafrost degradation.
This article describes the remarkable efforts of a team of scientists to extract cores from deep under a frozen lake in Siberia, Russia. PolarTREC teacher Tim Martin joined the project which will provide an astounding record of past climates preserved in layers of lake bed sediment. The sediment, withdrawn in cores and shipped to labs in Germany, represents a continuous
The attached Polar Oceans flyer, produced by the International Polar Year (IPY) Programme Office, provides summary information about the Polar Oceans and describes how the circulation in polar waters exerts a powerful control on the Earth's climate and carbon cycle. Activities attached to the flyer demonstrate the interconnectedness of marine life in the oceans and how the Polar Regions affect
The attached Lands and Life flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of terrestrial polar ecosystems, from southern cold maritime islands to dry continental deserts in Antarctica and from tree line across the continental tundra to remote northern islands in the Arctic. An attached activity allows students to build a small scale model of
The attached Ice Sheets flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of information about ice sheets in both the Arctic and Antarctica, followed by an activity which allows students to make their own realistic model of an ice sheet with commonly available materials.
The attached Changing Earth flyer, produced by the International Polar Year (IPY) Programme Office, includes a summary of the history of planet Earth and an activity involving the use of a rope as a timeline to represents the Earth’s history from the present to 65 million years ago.
This detailed animation shows how the Earth is lit by the Sun throughout the year. The lighting of the Arctic and the Antarctic is detailed for every month of the year to help explain, among other things, the resulting polar night.
