We recently reported the discovery of a regular corrugation pattern in the HIdisk of the isolated, edge-on spiral galaxy IC2233. Here we presentmeasurements of the vertical structure of this galaxy at several additionalwavelengths, ranging from the far ultraviolet to the far infrared. We find thatundular patterns with amplitude ~5''(~250 pc) are visible in a variety ofPopulation I tracers in IC2233, including the young-to-intermediate age stars,the HII regions, and the dust. However, the vertical excursions become lesspronounced in the older stellar populations traced by the mid-infrared light.This suggests that the process leading to the vertical displacements may belinked with the regulation of star formation in the galaxy. We have alsoidentified a relationship between the locations of the density corrugations andsmall-amplitude (~5 km/s) velocity undulations in the HI rotation curve. We areable to exclude several possible mechanisms for the origin of the observedcorrugations, including tidal interaction from a companion, Parkerinstabilities, or a galactic bore. Global gravitational instabilities appear tobe the most likely explanation, although local perturbations may also beimportant.
