Dear Colleagues, Please consider submitting an abstract to the 2020 Ocean Sciences Meeting session: ME007 - Exploring and Characterizing Deep and Coastal Ocean Soundscapes <https://agu.confex.com/agu/osm20/prelim.cgi/Session/84757>. Abstracts <https://www2.agu.org/en/Ocean-Sciences-Meeting/Pages/Abstract-guidelines> will be accepted until September 11. Please share this announcement with other interested colleagues and students. Apologies for cross-posting, let us know if you have any questions. The session description is below: The ocean is vast, sparsely charted, deep, and underexplored. The physical properties of the ocean enable sound waves to propagate and be detected over very long, at times even ocean basin-scale distances, and thus sound can be a powerful tool to detect and observe deep-ocean processes. For example, major storm events can significantly raise ambient sound levels in the deep ocean. Many marine animals, from shrimp to whales, use sound to communicate and assess their environment. The combination of biological, geological, physical, and anthropogenic sounds together make up the marine “soundscape”. Exploring marine soundscapes can lead to a better understanding of the ocean and characterization of these marine environments, as well as providing a measurement of current sound levels to compare against predicted future increases in anthropogenic sound sources. Further, ocean sound was recently identified as an essential ocean variable by the Global Ocean Observing System. This session aims to explore the holistic use of sound to characterize deep and coastal ocean areas, as well as discuss potential gaps in current understanding, and new ways to interpret and quantify ocean soundscapes.
