We study outflows in 130 galaxies with -22<MUV<-16 at z=3-9 identified inJWST NIRSpec and NIRCam WFSS data taken by the ERO, CEERS, FRESCO, GLASS, andJADES programs. We identify 30 out of the 130 galaxies with broad components ofFWHM~200-700 km/s in the emission lines of H${\alpha}$ and [OIII] that traceionized outflows, and find no excesses from the star-formation main sequence.Four out of the 30 outflowing galaxies are Type 1 AGN whose H${\alpha}$emission lines include line profile components as broad as FWHM>1000 km/s. Withthe velocity shift and line widths of the outflow broad lines, we obtain~80-500 km/s for the outflow velocities. We find that the outflow velocities asa function of star-formation rate are comparable to or higher than those ofgalaxies at z~1, accounting for the selection bias, while the outflowvelocities of AGN are large but not significantly different from the others.Interestingly, these outflow velocities are typically not high enough to escapefrom the galactic potentials, suggestive of fountain-type outflows, which areconcluded on the basis of thorough comparisons with recent JWST results. Weestimate mass loading factors ${\eta}$ to be 0.1-1 that are not particularlylarge, but comparable with those of z~1 outflows. The large fraction ofgalaxies with outflows (30% with high resolution data) provides constraints onoutflow parameters, suggesting a wide opening angle of >45 deg and a largeduty-cycle of >30%, which gives a picture of more frequent and sphericaloutflows in high-z galaxies.
