About once every year or two, physicist Albrecht Karle faces a five-day commute. And that timeline is only if everything goes perfectly.
The University of Wisconsin–Madison professor is a co-leader of operations for the IceCube Neutrino Observatory, a massive physics experiment at the South Pole funded by the US National Science Foundation and partners. And while, yes, Karle gets most of his work done at the offices of UW’s Wisconsin IceCube Particle Astrophysics Center in Madison, he does occasionally need to get to the Pole.
The first steps on his journey are a series of commercial flights from Madison to Los Angeles to Auckland, New Zealand, and on to Christchurch. Ideally, this takes 30 hours over two calendar days. Karle stays a couple of nights in Christchurch, home of the US Antarctic Program deployment hub, to pick up extreme cold-weather gear—parkas, gloves, hats, etc.—and do any check-in procedures with USAP.
Karle’s next stop is McMurdo Station, an international research facility run by NSF on the coast of Antarctica, and USAP’s logistics headquarters. Depending on which military transport plane he takes—a Boeing C-17 or a Lockheed LC-130—it could take four or seven hours, respectively.
At McMurdo, Karle must wait for the weather to permit the final leg of the trip. “It is not uncommon to spend several days in McMurdo,” he says. (Karle’s record is 10.) When it’s time, he takes a 3.5-hour flight on a ski-equipped LC-130 aircraft to reach the South Pole. Anyone or anything else that goes to the South Pole must take a similarly tedious route.
There’s a reason scientists have endured the challenges of the climate, the commute and the cost for over half a century—since members of the US Navy completed the original Amundsen–Scott South Pole Station in 1957. Despite all the trouble it takes to get there, the South Pole is an unparalleled environment for scientific research, from climate science and glaciology to particle physics and astrophysics.
The Particle Physics Project Prioritization Panel recently recommended, among their top priorities for the next decade, moving forward with two experiments based at the South Pole.
