Jets generated in the flow past a sphere moving vertically at constant speeds in a saltstratified fluid are observed by laser-induced fluorescence(LIF). In previous shadowgraph experiments, the jets are classified into seven types. In this study, density distributions in the vertical plane are observed when a thin jet or a broad jet is generated. It is confirmed experimentally that when the stratification is weaker and a broad jet is generated, density boundary layer is thicker than the case when the stratification is stronger and a thin jet is generated.
