  We present the results of a search for astrophysical sources of brief
transient neutrino emission using IceCube and DeepCore data acquired between
May 15th 2012 and April 30th 2013. While the search methods employed in this
analysis are similar to those used in previous IceCube point source searches,
the data set being examined consists of a sample of predominantly sub-TeV muon
neu- trinos from the Northern Sky (-5$^{\circ}$ < {\delta} < 90$^{\circ}$ )
obtained through a novel event selection method. This search represents a first
attempt by IceCube to identify astrophysical neutrino sources in this
relatively unexplored energy range. The reconstructed direction and time of
arrival of neutrino events is used to search for any significant
self-correlation in the dataset. The data revealed no significant source of
transient neutrino emission. This result has been used to construct limits at
timescales ranging from roughly 1$\,$s to 10 days for generic soft-spectra
transients. We also present limits on a specific model of neutrino emission
from soft jets in core-collapse supernovae.
