Much data on the Galactic polarized radio emission has been gathered in thelast five decades. All-sky surveys have been made, but only in narrow, widelyspaced frequency bands, and the data are inadequate for the characterization ofFaraday rotation, the main determinant of the appearance of the polarized radiosky at decimetre wavelengths. We describe a survey of the polarized radioemission from the Southern sky, aiming to characterize the magneto-ionicmedium, particularly the strength and configuration of the magnetic field. Thiswork is part of the Global Magneto-Ionic Medium Survey (GMIMS). We havedesigned and built a feed and receiver covering the band 300 to 900 MHz for theCSIRO Parkes 64-m Telescope. We have surveyed the entire sky betweendeclinations -90 and +20 degrees. We present data covering 300 to 480 MHz withangular resolution 81' to 45'. The survey intensity scale is absolutelycalibrated, based on measurements of resistors at known temperatures and on anassumed flux density and spectral index for Taurus A. Data are presented asbrightness temperatures. We have applied Rotation Measure Synthesis to the datato obtain a Faraday depth cube of resolution 5.9 radians per metre squared,sensitivity of 60 mK of polarized intensity, and angular resolution 1.35degrees. The data presented in this paper are available at the CanadianAstronomy Data Centre.
