Specialist in bioacoustics, he studies cetacean species to describe their populations and societies. He is currently working on the study of mother-calf interactions in humpback whales, on the analysis of surface social behaviours in sperm whales and on the description of underwater soundscapes. He is the author and co-author of more than 60 scientific papers. He was the curator of the Baleinopolis exhibition at the Palais of Porte Dor\u00e9e in Paris (<a href=\"https:\/\/youtu.be\/gRbQR77TrRM\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/youtu.be\/gRbQR77TrRM<\/a>) and of the photo exhibition &#8220;L&#8217;Oc\u00e9an c&#8217;est Vivant&#8221; at the Cit\u00e9 internationale in Paris and on the Seine river bank.

One of the objectives is to describe how the anthropic sounds impacts the marine ecosystem. Analysis focused on specific acoustic features including the types of sound, acoustic intensities, bandwidth, duration of the sound exposition. To answer these questions, recent studies were done on the cetacean species to evaluate the level of these effects, from behavior changes to beaching. Since 2007, thresholds were suggested to avoid temporary and permanent threshold shifts for 3 categories of cetaceans: \u201clow frequency cetaceans\u201d including the mysticeti species, \u201chigh frequency cetaceans\u201d including almost all the odontoceti species, and \u201cvery high frequency cetaceans\u201d including the small odontoceti species like the porpoises, the vaquitas\u2026 In our team, we focused on the manual and automatic annotation of the large dataset of acoustic recordings in order to use this information to train convolutional neural network (CNN). We built a platform to simplify this processing. Results show that after a short training session, non-expert annotators can be involved to identify specific underwater sounds, and they obtained close results than from expert annotators. Thus, citizen science seems to be a complementary option to increase the number of annotated datasets. The next step is to test different structures of CNN to optimize the classification of sounds from a catalog including sounds emitted by few cetaceans species and sounds from the large commercial ships. This work will contribute to mitigate the underwater noise pollution.\u00a0<\/p>\n<\/div><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"keynotes\">Back<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Analysis of Underwater Soundscapes Prof. Olivier Adam &#8211; Sorbonne Universit\u00e9, France Dr Olivier ADAM is Professor at the Sorbonne University, Paris, France.
