Dear colleagues, This message is for your information. The Laboratory of Applied Bioacoustics (LAB) of the Technical University of Catalonia (UPC) is coordinating an international project with different institutions to monitor noise and its effects on the marine environment. Amongst these institutions are the Japan Agency for Marine-Earth Science and Tecnology (JAMSTEC) who is responsible of detecting and analysing geohazards in Japan, and the Japan National Research Institute of Fisheries (FRA). Through this collaboration, we are constantly monitoring underwater noise off Japan and could detect and record the 11 March earthquake. If you are interested, you can access this recording and live monitor the sound of the afterschocks at http://listentothedeep.com , in the "Listen on site" section. This data constitute a unique opportunity to understand the acoustic relationship between natural underwater events and the behaviour of cetaceans. With kind regards, Michel André Maria Morell Laboratori d'Aplicacions Bioacústiques Centre Tecnològic de Vilanova i la Geltrú Universitat Politècnica de Catalunya Avda Rambla Exposició s/n 08800- Vilanova i la Geltrú (Barcelona)SPAIN telf: 0034 938967290 http://www.lab.upc.es maria.morell@lab.upc.edu
