Abstract :
The SMO (Submarine Multidisciplinary Observatory) project aims at performing multidisciplinary studies in deep-sea based on acoustic detection. SMO will be a 3D array of 18 broad-band (10Hz - 70kHz) hydrophones installed at 3500m water depth. Deployment is foreseen in the beginning of 2012 and operation will continue for several years. The height of the array will be about 400m. SMO will be directly connected to shore though an electro-optical cable. Hydrophones will be sampled at 192kHz/24 bit underwater, all sensors will be phased and synchronized with a common master clock from shore. A novel technology for underwater GPS time-stamp of data was implemented and tested. Data from deep-sea will be available to the science community in real-time. SMO will be mainly addressed to detection of bioacoustic sounds (marine mammals), acoustic environmental monitoring, tests of novel tsunami detection technique and studies on acoustic neutrino detection. The status and goals of the project will be presented.
