Neutrino production and oscillation physics can be studied by utilizing the\nvery high flux of atmospheric neutrinos observed with IceCube. In a Cherenkov\nmedium such as ice, atmospheric muon neutrino interactions create tracks while\ncascades (showers) are produced by atmospheric electron neutrinos and by\nneutral current interactions of all flavors. We present the first detection of\natmospheric neutrino-induced cascades at energies between 30 GeV and 10 TeV\nusing the DeepCore array of the IceCube detector. Using 281 days of data, 1029\nevents are observed with 59% predicted to be cascades.\n
