In a paper recently published in the Journal of Glaciology, the IceCube Collaboration presents a study of South Pole climate over the past 100,000 years, using high-resolution 3D laser images of the ice sheet. […]
That’s IceCube winterover Ian Rees (facing) near the drill while it’s being prepared to access a rod well, which is a deep cavity used to melt ice for drinking water. Rod wells are named after Paul Rodriguez, an Army engineer who developed them while at Camp Century in Greenland in the early 1960s. […]
This austral summer, on November 4, Ian Rees was the first IceCuber to reach the Amundsen-Scott station, after a long trip from Boulder, Colorado. From now until the end of the IceCube polar season, 20 people will fly to the Pole from Madison, Maryland and Delaware in the US, but also from Canada, Germany, Sweden, and Belgium. […]
In a new study, the IceCube Collaboration searches for neutrino-induced particle showers in one year of data taken during the construction phase of IceCube, when about half the detector was operational. Above 100 TeV, a 2.7σ excess of events was found, which is consistent with results published by the IceCube Collaboration in Science. The current paper has been submitted to the journal Physical Review D. […]
Open coat? No hat? It must be summer at the South Pole. Well, although it’s sunny outside it would probably be a stretch to call it warm, for those of us not used to it anyway. Dag Larsen, one of IceCube’s two winterovers for this season, has finally arrived (above), and he may or may not be used to the cold, but one thing is sure—he has plenty of time to get used to it. […]
In an analysis published today, the IceCube Collaboration reports on a search for a diffuse astrophysical neutrino signal, looking at high-energy upward-going muon tracks, with data taken between May 2009 and May 2010, when the detector was running in its 59-string configuration. The search found a high-energy neutrino excess of 1.8σ compared to the background scenario of a pure conventional atmospheric model, a measurement consistent with the astrophysical neutrino flux described in Science. The results of this research have been submitted to Physical Review D. […]
The IceCube Neutrino Observatory is a demonstration of the power of the human passion for discovery, where scientific ingenuity meets technological innovation. Today, nearly 25 years after the pioneering idea of detecting neutrinos in ice, the IceCube Collaboration announces the observation of 28 very high-energy particle events that constitute the first solid evidence for astrophysical neutrinos from cosmic accelerators. Details of the research appear in an article published tomorrow, November 22, in Science. […]
Outgoing winterovers Felipe Pedreros (left) and Blaise Kuo Tiong (right) greet newcomer Ian Rees (center) on his arrival. Thanks to Felipe and Blaise for a great year of photos and reports, and welcome to Ian and Dag (Larsen, still to come), fresh and ready to capture the year’s adventure ahead. […]
It always seems as if they have just about everything at the South Pole, but apparently they didn’t have a unicycle. Until recently. Winter is officially over, and new arrivals to the station have come bearing goodies of all sorts, from “freshies” to toys—like this unicycle, which IceCube winterover Blaise is testing out in good form. […]
Life’s a tradeoff. At the South Pole, when winter comes to a close, you trade cold, dark, isolated for (still) cold, but bright, and less isolated. With the sun out, you also get sundogs—scientific name, parhelion. The tradeoff there? No more auroras for a while. […]
