Title: Probing the Extraplanar Diffuse Ionized Gas Properties of M33

Abstract: In disk galaxies, extraplanar diffuse ionized gas layers have important implications for the transfer of mass and energy between the disk, halo, and intergalactic environment due to star formation feedback. However, there is not yet enough evidence to determine whether the dynamics of these layers are best described by equilibrium or non-equilibrium models. While studies of the kinematics of these layers have focused on high-inclination galaxies, understanding their three-dimensional dynamics will require studies of their kinematics in low- and moderate-inclination galaxies. Here, we propose SparsePak IFU emission-line spectroscopy of the extraplanar diffuse ionized gas in the nearby, moderately-inclined disk galaxy M33 ($D \sim 0.9$ Mpc; $i \sim 54^{\circ}$). We propose SparsePak IFU observations at low spectral resolution ($R \sim 4000$) to enable future kinematic observations at high spectral resolution ($R \sim 10000$) by verifying the detection of diffuse ionized gas, determining pointings of particular interest, and developing an effective approach to sky subtraction.
