The Herschel Inner Galaxy Gas Survey (HIGGS) is an approved Open Time Key Project of the Herschel Space Observatory. HIGGS aims to investigate the inflow of matter in the bulge of the Milky Way to determine the relationship between central black holes and their host galactic bulges and thus the causes and mechanisms of starbursts. The gas in closed orbits in the bar of the Milky Way provides a means to study in detail the accretion processes leading to starbursts and active galactic nuclei. Shocks effectively transfer some fraction of the clouds' orbital kinetic energy into heat which escapes through dust continuum and line emission. By measuring this emission, we can estimate the amount of orbital energy that has been dissipated and constrain estimates of the mass inflow from the decaying orbits. However in order to fully approach this problem, it is critical to have a a full understanding of the atomic and molecular components of the material in the HIGGS fields. While we have access to a wide range of surveys that cover the HIGGS fields, it has become clear that what is missing are the high spatial resolutions that MOPRA can provide in the 3mm band.
