N2  - Polar Ecosystems Are Undergoing Major Changes Driven By Sea Ice Decrease, Air Temperature Warming And Increasing Anthropogenic Activities. The Ocean Acoustic Environment, Called The &Ldquo;marine Soundscape,” Consists Of Biological, Abiotic And Anthropogenic Sounds. In Polar Seas, Biological Sound Sources Include Marine Mammals, Fishes, And Benthic Organisms. Abiotic Sources Correspond To Physical Processes Such As Ice Dynamics And Meteorological Events. Contributors To Anthropogenic Noise Are Classically Commercial Shipping And Military Activities. in Order To Monitor How Anthropogenic Changes Is Impacting Polar Ecosystems, The First Stepis To Identify, Describe And Quantify The Features Of Soundscape Contributors. Since 2013, Underwater Acoustic Recorders Have Been Deployed Up To Several Months In Several Locations Of The Arctic (Spitzbergen, Greenland) And The Antarctic.in The Arctic, Results Show A Strong Variation Of Ambient Noise Levels Between Sites And Seasons. Noise Levels Measured In Spitzbergen In October 2013 Are Up To 15 Db Re1upa Higher Than Those Measured In Mai 2013, Due To An Increase In Wave And Water Flow Noises. The Daneborg Acoustic Recordings Display Extreme Differences In Noise Levels Between August 2015 And August 2016 With A Very Quiet Environment In 2015 And Many Ice Sounds In 2016.antarctica Soundscape Is Dominated By Biological Sound Sources: Benthic Sounds And Marine Mammals Vocalizations (Including Weddel Seals, Orcas And Blue Whales).
