Antarctic educator, Mark Walsh, created this video for the PolarTREC 2013 spring online professional development course. This video uses the concept of Density to explore how mountains are built as well as how to throw a good Cinco de Mayo party at McMurdo Station Antarctica. He uses the Dr. Samantha Hansen's Transantarctic Mountains work as an example of mountain building.
This student lesson focuses on plate tectonics and large-scale system interactions, utilizing PolarTREC teacher Brian DuBay's Transantarctic Mountains expedition videos.
Objectives: The student will investigate, make observations, and analyze geologic processes of plate tectonics.
Key concepts include:
a) how geologic processes are evidenced in Antarctic mountains;
b) tectonic processes (compressional, tensional, and transversal forces).

Students will conduct a demonstration that will help them gain a better understanding of the water cycle and runoff in a watershed. They will be able to replicate arctic and non-arctic watersheds by varying the size of the watershed. They will be able to visualize the difference in runoff by creating hydrographs of these different locations.
The seismic equipment that is being used for TAMNNET (studying the Transantarctic Mountains) was specially engineered for use in polar climates. Polar projects commonly require a level of support that is several times that of seismic experiments in less demanding environments inclusive of very remote deployments. This site offers great engineering insights, design drawings, and additional related links.
POLENET (The Polar Earth Observing Network) is a global network dedicated to observing the polar regions in a changing world.
The project is focused on collecting GPS and seismic data from autonomous systems deployed at remote sites spanning much of the Antarctic and Greenland ice sheets. GPS and seismic measurements together provide a means to answer critical questions about ice
Ice Stories is a project from the San Francisco Exploratorium as 'Dispatches from Polar Scientists' as an outreach effort from the 2007-08 International Polar Year. The Antarctic Geology focuses on mountains in East and West Antarctica. Be sure to check out the videos associated on the website "Secrets of Bedrock" and "Mystery Mountains".
Rachel Potter presents her research on the use of radar to measure surface currents in the top 2 m of the water column in the Chukchi Sea. The information gained from her research allows her to determine where water is going and how fast it is flowing, which can aid in issues of search and rescue, contaminant spills, marine navigation
NBC Learn, in partnership with the National Science Foundation, explores the impact that climate change is having on our planet. In this video, IARC's Dr. Katey Walter Anthony and IARC affiliate Dr. Vladimir Romanovsky are interviewed about permafrost, methane, and their impacts on the environment. Viewers are given an explosive demonstration.
Melting permafrost in a warming world could mean lots of greenhouses gasses, especially methane, released into the atmosphere. But it also means an unusual community of soil bacteria coming out of hibernation, so to speak. A new study looks at what those permafrost microbes do, exactly, as their environment warms up.
