Kaufmann, P. ; Zisk, S. ; Scalise, E., Jr. ; Schaal, R. E. ; Gammon, R. H. Abstract An extensive low-flux-limit survey of Southern Hemisphere celestial water vapor sources has been carried out. Observations were made at 115 different potential source positions, with upper limits for line detection ranging from 7 to 80 Jy. Fifteen Galactic H2O masers were discovered, and one weak one was confirmed. Some of them were found in H II regions in which type-I OH emission has not yet been detected. A selection of H II regions observed in the Carina Nebula yielded negative results. A survey of H II regions in the Magellanic Clouds also yielded negative results for the presence of very strong H2O emitters.
