A new high-sensitivity HI survey of the southern sky was made south
of Declination 
, at the Instituto Argentino de Radioastronomía
(IAR), on a
half-degree grid in galactic coordinates. A total of 50980 positions were
observed. One of the goals of this survey was to search for high velocity
clouds (HVCs). The HI profiles have been smoothed to a velocity resolution
of 8 km s-1. The resulting rms noise falls in the range 0.015 to 0.020 K.
We have detected 6848 high velocity (HV) components.
