Dome A, the highest plateau in Antarctica, is being developed as a site for an astronomical observatory. The planned telescopes and instrumentation and the unique site characteristics are conducive toward Type Ia supernova surveys for cosmology. A self-contained search and survey over five years can yield a spectro-photometric time series of not, vert, similar1000 z<0.08 supernovae. These can serve to anchor the Hubble diagram and quantify the relationship between luminosities and heterogeneities within the Type Ia supernova class, reducing systematics. Larger aperture (greater-than or equivalent to94-m) telescopes are capable of discovering supernovae shortly after explosion out to z not, vert, similar 3.These can be fed to space telescopes, and can isolate systematics and extend the redshift range over which we measure the expansion history of the universe.
