DESCRIPTION:Speakers: Michael Burton (University of New South Wales)\nThe 
 Mopra Southern Galactic Plane molecular gas survey is the next generation 
 CO survey of the distribution and dynamics of the molecular gas along the 
 southern galactic plane.  Being conducted with 0.6 arcmin and 0.1 km/s res
 olution\, it provides an order of magnitude improvement in both spatial an
 d spectral resolution over the Dame et al 2001 survey\, currently our stan
 dard source of reference on the distribution of the molecular gas in our G
 alaxy.  It is also being conducted in three isotopologues of the molecule\
 , not just one\, so providing information on the optical depth (and hence 
 the column density).  Knowledge of the distribution of the molecular gas a
 s a function of distance from the Sun is a key input for the interpretatio
 n of TeV gamma ray images\, for molecules provide the greatest column dens
 ities of nuclei that high energy cosmic rays might collide with\, in the h
 adronic scenario for TeV gamma ray production.  With CTA's resolution appr
 oaching an arcminute\, an order of magnitude improvement on the HESS\, it 
 will be essential to know the distribution of the gas on this scale in ord
 er to be able to fully interpret the gamma ray images it will produce.  Th
 e Mopra CO survey is being conducted with the CTA's needs as a primary dri
 ver.  This talk will describe the status of the Mopra CO survey\, and illu
 strate the difference that the order of magnitude improvement in spatial r
 esolution brings to the cartographic charting of the Galaxy's interstellar
  medium.\n\nFurther details at the project website: www.phys.unsw.edu.au/m
