We present first results from the analysis of the nuclear molecular gas distribution in the Keck OSIRIS Nearby AGN (KONA) survey. The KONA survey consists of 40 Seyfert galaxies in which the two-dimensional molecular gas, traced by the 1-0 S(1) H2 2.12 micron emission, is measured across the central few hundred parsecs down to spatial scales of 5-10 parsecs. Results verify those from previous smaller samples in which Seyferts are found to have a thick nuclear disk of molecular gas. A comparison of the characteristics of the nuclear disks in Seyfert 1s versus 2s will be presented, including measurements of the full-width-half-maximum of the azimuthally averaged gas distribution and Sersic fits to these distributions.
