We present a deep (657 ksec total) Chandra observation of the cool core cluster, Abell 2052. This well-known system is a clear case of radio source / intracluster medium (ICM) interaction, where well-defined bubbles have been inflated by the AGN-powered radio lobes. The new, deep Chandra dataset allows us to examine the temperature and abundance structure in the ICM in much greater detail. We will further parameterize ripple-like features in the surface brightness, allowing us to distinguish among sound waves, shocks, and cold fronts. Investigation of the source of pressure support within the bubbles will be presented, as well as comparison of the cooling and star formation rates in small regions in the cluster center. Support for this work was provided by NASA through Chandra award GO9-0147X.
