The DeepCore detector, the low-energy extension to the
IceCube Neutrino Observatory, instruments a fiducial volume of up to 35MT
with an energy threshold as low as about 10 GeV. Much of the
success of the achieving a pure neutrino sample in the detector is
the use of the IceCube array as the world's largest active veto for
cosmic ray muons. It is possible to further infill the DeepCore
array to achieve lower detector energy thresholds and higher
precision measurements in the deep ice. We discuss here a two phase
approach to such an infill array. The first phase detector we
consider is similar in design to DeepCore, has goals of 10MT with
sub-GeV energy sensitivity, providing improved sensitivity for
indirect WIMP searches, atmospheric neutrinos, Galactic Center point
sources and a first step towards proton decay searches. The
potential second phase would seek to achieve a few MT fiducial
volume with an approximate 10 MeV energy threshold for a large-scale
physics program that includes proton decay, supernova neutrinos and potential
future long baseline efforts. Presented will be the current status
of the ongoing physics feasibility studies for these new arrays buried in the ice.
