Dear All, We would like to draw your attention to an initiative from the Laboratory of Applied Bioacoustics (LAB) of the Technical University of Catalonia, to present, explain and promote the research conducted on the effects of artificial noise on the marine environment. We have designed an interface (www.sonsdemar.eu; Catalan for 'sounds of the sea') where the visitors, in addition to learn about the acoustic processes in cetaceans, will be able to listen to natural, biological and anthropogenic sound sources that are nowadays co-existing in the oceans, experiencing the need of research to get back to a natural acoustic balance of the seas. With kind regards, The Sons de Mar Staff Laboratori d'Aplicacions Bioacústiques Universitat Politècnica de Catalunya (UPC) info@lab.upc.edu http://www.lab.upc.es Centre Tecnològic de Vilanova i la Geltrú Avda.
