Listening to the Deep-Ocean Environment Results The system modules allow to automatically extract a subset of acoustic events only contaminated with a very small proportion of sounds from shipping. The modules can be adapted to any frequency bands and classes of impulses, tonal sounds or other acoustic signals. Possible applications of the system are the real time: (1) Discard of undesired data before transmission or storage; (2) Selection of a specific subset of a long recording to estimate abundance, daily or seasonal activity patterns of cetacean or shipping; (3) Mitigation of potentially harmful anthropogenic activities. 5-7 Oct. 2009All Regions Workshop #2
