- We present a summary of the latest atmospheric oscillation parameter measurements using DeepCore, part of the IceCube Neutrino Observatory. With 30 megatonnes of fiducial volume, DeepCore can detect atmospheric neutrinos down to 5 GeV, probing the energy range of the first atmospheric oscillation maximum for neutrinos crossing the Earth. Under the assumption of a unitary mixing matrix, three independent binned analyses have been performed with different reconstructions, event selections, and systematics. Despite the differences, the measurements of Δ \Delta m2 ^2 and sin2θ23 ^2 \theta_{23} support our latest published result and are consistent with and of similar precision to long baseline experiments.
