Soundscape analysis in the Southern Ocean using elephant seals as acoustic glider of opportunity
International audience The underwater ambient sound field contains quantifiable information about the physical and biological marine environment. Since 2011, we have been annually collecting underwater data over the migratory routes of bio-logged Southern Elephant Seal (SES). As done with classical...

International audience The underwater ambient sound field contains quantifiable information about the physical and biological marine environment. Since 2011, we have been annually collecting underwater data over the migratory routes of bio-logged Southern Elephant Seal (SES). As done with classical underwater gliders, we extract from these data very high resolution (approximately 30 min/400 m) ocean ambient noise measurements. In this conference, we present an overall picture of the low-to-medium frequency (10–6000 Hz) ambient noise distribution and its variability in time and space at a regional scale within the Indian Ocean. We detail our methodology to extract robustly the measurements usually performed on ocean ambient noise, such as sound pressure level over different frequency bands and their statistical percentiles.
