New $\nu_{\mu}$ Disappearance Results with IceCube/Deepcore

Located at the South Pole Station in Antarctica, the IceCube Neutrino Observatory is the world's largest neutrino telescope. In the clearest part of the ice sits a more densely instrumented section, DeepCore, that is able to measure neutrinos from 10-80 GeV. Using DeepCore, neutrino oscillations can be observed via $\nu_{\mu}$ disappearance. This talk will highlight the new and greatly improved atmospheric disappearance results from IceCube/DeepCore.
