We present the results of an on-going study of the nuclear molecular gas kinematics in a sample of 40 galaxies from the Keck OSIRIS Nearby AGN (KONA) survey. The velocity and velocity dispersion of the molecular gas, traced by the 1-0 S(1) H2 2.12 micron emission, are measured within the central few hundred parsecs down to spatial scales of 5-10 parsecs. The azimuthally averaged velocity dispersion and gas velocity are used to assess variations in the ratio of the velocity to velocity dispersion as a function of radius and the implied thickness of the gas disk is estimated. A comparison of the characteristics of the nuclear disks in Seyfert 1s versus 2s will also be presented.
