The determination of the neutrino mass hierarchy is among the most fundamental questions in particle physics. The recent measurement of a large mixing angle between the first and the third neutrino mass eigenstate and the first observation of atmospheric neutrino oscillations at tens of GeV with neutrino telescopes opens the intriguing new possibility to exploit matter effects in neutrino oscillation to determine the mass hierarchy in the neutrino sector. We will discuss in this talk the ongoing IceCube/DeepCore activities and the potential of the PINGU extension with a further lowered energy threshold. The status of calculations concerning PINGU's sensitivity to the mass hierarchy will be reported.
