description: In this study, an imaging method to resolve horizontal oxygen concentration fields is presented. The technique is based on the transformation of a concentration gradient into fluorescence intensity. A water-soluble ruthenium complex indicator is quenched by oxygen. The boundary layer imaging setup has been mounted on a small annular wind-wave tank at the IUP Heidelberg. Measurement series have been performed for three different indicator concentrations (0.03 mmol/L, 0.07 mmol/L and 0.11 mmol/L) at wind speeds ranging  from 2 m/s to 7 m/s. The recorded images clearly show gas transport footprints, which are qualitatively discussed. The mean brightness of image sequences is quantitatively analysed. The oxygen quenching method has been implemented, and the setup is ready for further use.
