dc.descriptionWe present preliminary results of VLA HI imaging of selected Virgo cluster galaxies. The goal is to study environmental effects on galaxy evolution. Our sample of 41 galaxies is spread throughout the cluster and spans a wide range in star formation properties. Here we present the total HI maps of 13 galaxies. We find a number of galaxies with extended HI tails, almost all pointing away from the cluster center. Truncated HI disks are found close to the center but also in the outer region. Some galaxies near the cluster center show compression of the gas on one side. Multiwavelength data of NGC 4569 and kinematics on NGC 4396 indicate that some of the HI is extra-planar. These preliminary results on the HI morphology already suggest that a variety of environmental effects such as ICM-ISM interactions, harassment, tidal interactions or mergers may be at work to affect the evolution of galaxies.
