  The IceCube Neutrino Observatory is a cubic kilometer-sized detector designed
to detect neutrinos of astrophysical origin. However, muons created by cosmic
rays interacting in the atmosphere pose a significant background for these
astrophysical neutrinos particularly in the southern equatorial sky.
Identifying neutrino events that start in the detector allows us to reduce the
atmospheric muon component while retaining a high rate of starting neutrino
events. The method presented today also rejects atmospheric neutrinos if they
are accompanied by muons from the same cosmic ray shower, lowering the 50$\%$
purity threshold for astrophysical-to-atmospheric neutrinos from 100 TeV to ~10
TeV at declinations less than -25{\deg}. We use 10$\%$ (burn sample) of 9.5
years IceCube data to demonstrate the status of this dataset. We outline a
planned measurement of the diffuse neutrino flux inclusive of theoretical and
detector systematic uncertainties. In addition, we discuss searches for
neutrino point sources and diffuse galactic plane neutrino emission in the
Southern sky and plans to release high astrophysical-purity real-time alerts to
the multi-messenger community.
