Dear colleagues, With great pleasure we announce that OCEANOISE2015 will held be next year in Vilanova i la Geltrú (Barcelona, Spain) from 11-15 May 2015. The growing scientific and societal concern about the effects of underwater sound on marine ecosystems has been recently recognized through the introduction of several international initiatives aiming at measuring ocean noise at large spatial and temporal scales. This will be a "conference with a difference", as it aims at maximising the dissemination of new science. OCEANOISE2015 novel format will favour a dynamic exchange of the latest findings in the field of ocean noise in order to assist in providing ocean users with the best scientific knowledge and technical solutions to address operational and environmental issues. OCEANOISE2015 will bring together international leading experts in noise measurement, modeling and mapping, physiological and behavioural effects as well as regulation and mitigation procedures. The strong opportunities for good interaction and tangible impacts after the conference make this an ideal occasion to showcase your research in the field of ocean noise as well as highlight priority topics to the international community and stakeholders. On behalf of OCEANOISE2015 Science Committee, wehave the pleasure to invite you to submit abstracts at www.oceanoise2015.com<http://www.oceanoise2015.com> before January15, 2015. With acoustically sound regards, Michel André & Peter Sigray OCEANOISE2015 Chairs Dr. Michel André Laboratori d'Aplicacions Bioacústiques Universitat Politècnica de Catalunya (UPC) michel.andre@upc.edu<mailto:michel.andre@upc.edu>, http://www.lab.upc.es Centre Tecnològic de Vilanova i la Geltrú Avda.
