PolarTREC expeditions to the Arctic and Antarctica can be found here starting in 2007 to present. You can also access archived expeditions to the Arctic that took place through TREC in 2004-2006. Journals, photos, ask the team forums, and information about each expedition can be found by following the links to all the expeditions. Use the Expedition Search feature to narrow your choices or find a particular expedition or region. Use the Members feature to find teachers and researchers involved with PolarTREC expeditions.
Another interesting perspective for viewing expeditions are Projects. Projects are expeditions that had teachers for more than one year. You can learn more about the science and see all the teachers and researchers involved in the research project over two or more years. You can also access all the related project resources (presentations, lessons, PolarConnect events, etc.) related to the projects.
Effects of Lemmings on the Arctic Tundra Ecosystem
Dates
10 July 2022 - 5 August 2022
Location
Utqiagvik, Alaska
What Are They Doing?
The team plans to use observations and experiments and models to understand how the fluctuations in the numbers of small mammal herbivores on the tundra, both within and between years, affect tundra ecosystem function (such as the abundance of different types of plants, the quality of plant litter and nutrient cycling) and energy balance. They will determine natural changes in small mammal population sizes in three different Alaskan tundra ecosystems (at Utqia?vik, Nome and Toolik Lake), and also use experiments in each ecosystem where they control the number of small mammals that have access to small areas of the tundra, to determine how this affects the way the ecosystem works.
