ResumenBased on citizen science data, the study presented here aims at developing a simple method to automatically compute the water transparency from underwater images taken by volunteer divers. Volunteers are asked to take pictures of a set of two targets whose pattern we have optimised. We developed a method to automatically estimate the distance between the two images from the mere picture and then to compute an attenuation coefficient. The method has been tested on pictures taken in the Wadden See, the Netherlands, during a campaign in Easter 2014. The results are stable and coherent with results found based on other instrumentation. This procedure will allow to generate large data sets, mainly on coastal areas, that could not be easily obtained by conventional observation methods. We will thus be able to get information on the constant evolution of the water transparency in the coastal regions, the most complex ones from the optical point of view, but of interest for many areas such as health, environment, fishing or leisure. This work has been realised within the European FP7 Citclops project
