Antarctic Expeditions: A Tradition of Discovery
For decades, the University of Wisconsin–Madison has sent its scientists to Antarctica, where harsh conditions have not deterred their pursuit of knowledge. Since the 1950s, UW researchers have studied geology, meteorology, climate change, and wildlife ecology on the continent, contributing steadily to global scientific understanding. In recent years, however, these expeditions have helped launch ambitious projects—none more so than the construction of IceCube, a leading antarctica neutrino telescope.
IceCube: A Neutrino Telescope Deep Within the Antarctic Ice
The IceCube project, hosted by UW-Madison and funded with a $242 million National Science Foundation grant along with $30 million from German and Swedish partners, is one of the largest 'Big Science' projects in operation. This icecube project also receives contributions from academic and research institutions in Belgium, Japan, New Zealand, the UK, and other parts of the United States, involving over 400 personnel in its construction and operations.
Physics professor Francis Halzen, who secured the NSF grant and is IceCube’s principal investigator, leads the project from Madison. Mark Krasberg, a UW-Madison physics researcher, spends every Austral summer at the South Pole, overseeing operations and contributing to the telescope's construction and functionality.
How IceCube Tracks Cosmic Neutrinos
The IceCube neutrino observatory is designed to detect neutrinos—elementary particles with little mass that travel at or near light speed, passing through ordinary matter largely undisturbed. The telescope detects these elusive particles by utilizing 86 strings of Digital Optical Modules (DOMs), each equipped with basketball-sized, ultra-sensitive sensors embedded deep within the ice sheet. These antarctic ice sensors detect Cherenkov radiation emitted when neutrinos interact with the ice, allowing scientists to trace their origins back through space.
As of early 2009, 59 of the planned 86 DOM strings were deployed, keeping the project on track for completion in 2011. Once operational, IceCube will measure a full cubic kilometer—roughly analogous to the length, width, and depth of State Street in Madison—and is expected to remain active for decades. According to Krasberg, the system already detects about two neutrinos per hour arriving from below the Earth’s surface. Scientists aim to create deep-space maps and animations revealing sources of cosmic neutrinos, such as black holes, gamma-ray bursts, and supernova remnants.
UW-Madison Researchers in Diverse Antarctic Fields
The south pole research led by UW is not limited to particle astrophysics. Soils science professor Jim Bockheim investigates how Antarctic soils form through glacial cycles, while Christine Ribic, an associate professor of wildlife ecology, studies the impact of climate change on vulnerable Adélie penguin populations. Emeritus geology professor Charles Bentley, with over 15 trips to the continent, leads efforts to obtain two-mile-long ice core samples to build climate records spanning tens of thousands of years.
Matthew Lazzara, a research meteorologist at UW’s Space Science and Engineering Center, heads a team maintaining more than 60 automated weather stations—around half of all such stations in Antarctica. These stations, supported by the NSF and augmented by satellite data, serve as critical resources for ongoing climate studies antarctica, forecasting, and operational planning.
Challenges and Unique Experiences in Antarctic Research
Antarctic fieldwork is not for the faint of heart. The journey takes days via Los Angeles and Christchurch, New Zealand, before a long final flight to the ice. Scientists and support staff stay in shared dormitories, often missing holidays and family milestones during six- to eight-week seasons. Weather extremes are routine, with wind chills reaching minus-70 degrees Fahrenheit and wind speeds recorded as high as 137 miles per hour.
Despite hardships, the sense of mission remains strong. McMurdo Station offers a community of 800–1,100 scientists and staff, shared resources, and cross-national camaraderie. Amenities at the new $200 million South Pole Station include games, a greenhouse, and communal meals—essential for morale in such a remote environment.
Reflections from the Field
Researchers like Krasberg and Lazzara document their experiences through photos, videos, and blog posts, showcasing the scale and beauty of Antarctica as well as the complexity of modern antarctica science expeditions. Their efforts, and those of many international collaborators, continue to advance human understanding of the universe, climate, and the unique environment at the bottom of the world.
