Photographs, radial velocity measurements, and spectrometry for gaseous filaments stretching 25 arcmin from the galaxy NGC 5128 toward the NE radio lobes, are presented with emphasis on the properties of extended emission regions. Fine structure is found on a scale of a few arc seconds in the velocity pattern and emission line strengths, and regions of highly structured and turbulent gas with velocity differences of 200-300 km/s are frequently observed. Gas is found moving towards the observer at 300-400 km/s, with some gas leaving the galaxy permanently. Dominant sources for excitation of emission regions are discussed, and energy dissipation within a hot turbulent gas is considered the most likely. Possible origins of the gas are also considered, suggesting that observable regions of optical emission are produced within gas which is swept from central parts of the galaxy.
