Abstract

A new approach is described to image near-surface water side concentration fields at the air-water interface and wind waves at the Heidelberg Aeolotron wind-wave tank to study the transport mechanisms of air-sea gas exchange. The concentration fields are made visible by fluorescence imaging, stimulated by a 450 nm laser diode array, with 1-propylamine and pyranine. Light field imaging with seven cameras retrieves also the 3-D shape of the water surface. An additional laser line with 410 nm laser diodes is used to measure wind wave height directly and for precise camera alignment.
