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.
IceCube and The Askaryan Radio Array 2021
15 December 2021 - 15 January 2022
South Pole Station, Antarctica
What Are They Doing?
IceCube is located at the South Pole and records the interactions of a nearly massless sub-atomic messenger particle called the neutrino. IceCube searches for neutrinos from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars.
The IceCube Neutrino Observatory is a powerful tool to search for dark matter, and could reveal the new physical processes associated with the enigmatic origin of the highest energy particles in nature. In addition, IceCube studies the neutrinos themselves using the 100,000 neutrinos detected per year produced by cosmic rays in the atmosphere. Their energies far exceed those from accelerator beams. IceCube encompasses a cubic kilometer of instrumented ice, and is the largest detector by volume ever built.
The fully built ARA project, also located at the South Pole, will have an effective volume 100 times bigger than IceCube. The trade off is that it is only capable of observing radio waves from extremely high energy neutrinos, a million times more energetic than the neutrinos produced by cosmic rays in the atmosphere. This neutrinos are extremely rare, which is why such a large detector is needed to increase the chance of seeing one.
