In the fight against marine pollution, the knowledge of the mixing dynamics between different liquids is of first priority. When shipwreck occurs with chemical payload, the chemicals can follow different behaviors through the water column (floating, dissolving, sinking, evaporating …). Floating and dissolving products are the main categories interfering with the local in-situ responders. Moreover these chemicals can be contact corrosive for rescue divers, generate toxic cloud and even explosive atmosphere for rescue aircraft and crew. This study mainly focuses on this liquid-liquid interaction. First tests with shadowscopy have shown trailing edge dissolution smears and also characteristic droplet shapes throughout the water column droplet rise [1]. Digital holographic set-up coping with high speed imaging has been designed to enhance the quality of the droplet contours and to measure the critical sizes. First results about n-butanol dissolution in seawater and the analysis procedure are presented.
