Exceptions to the Antarctic Treaty .. in the name of science

With the Antarctic Treaty all nations have agreed to eventually remove everything from the continent and not leave any trash etc behind. Last night I learned that the IceCube experiment required an exception. With 5000 photomultipliers frozen 2.5km deep into the ice there is no chance for a post-operation cleanup or removal. The IceCube detectors will stay frozen in the Antarctic ice forever. Or until the glacier pushes them off the continent in millions of years. At Pole the glacier speed is about 10m/year.  The distance to McMurdo is about 1100km. The Transantarctic Mountain Range is in between.
