In order to study the effect of gravity on Marangoni convective phenomena, Marangoni convection in a silicone oil liquid bridge that was simulating a half floating zone was observed under 1 g and µg conditions. The effect of gravity on the velocity distributions of laminar Marangoni convection was clarified. Marangoni convection is dominant at the interface; however, in bulk, gravity has an effect on the velocity field. The onset of temperature oscillation was observed under µg while a capsule was freefalling. The fundamental frequency of temperature oscillation under µg conditions was smaller than that under 1 g conditions when the non-dimensional liquid bridge volume was V /Vo=73.8 vol%, Fundamental frequency of temperature oscillation under 1 g conditions, however, was smaller than that under µg conditions when the liquid bridge volume was V /Vo=88.1 vol%. From these results, we can see that the fundamental frequency of temperature oscillation between under 1 g and µg condi­tions depends on the liquid bridge volume. Temperature oscillation amplitude of under µg was smaller than that under 1 gin both of the V /Vo=73.8, 88.1 vol%.
