Wilderness Research Foundation (USA) has developed two teaching modules based on a project we conducted in the Antarctic Peninsula in January 2010. They're available free for any educator interested in reviewing them for classroom use. The project concerned the collection of soil samples for the potential corroboration of a new conception of the carbon cycle. The principal investigator
The Alfred Wegener Institute developed a corer for use in ice covered areas such as the Antarctic Ice Shelf. The sampler can be lowered and heaved through several 100 m deep ice boreholes. This resource explains the technology of this polar science tool.
