2. How have human activities affected the global ocean soundscape compared with natural changes over geologic time?What are the current levels and distribution of sound in the ocean?What are the trends in sound levels across the global ocean?How does ocean sound currently affect important marine animal populations?What are the potential future effects of sound on marine life?IQOE Fundamental Questions
3. SCOR and POGOIQOE Science Committee: Forms new working groups when necessary, oversees all IQOE activities, and manages standalone activities, such as the creation of the global hydrophone network and the Ocean Sound EOV Implementation Committee.Structure of IQOE Management9 ENDORSED PROJECTSIQOE endorses national and regional projects that contribute to answering IQOE’s fundamental questions. IQOE does not manage these projects but gives them extra visibility and helps them interact with other endorsed projects and IQOE WGs. Cooperation among groups has contributed to progress in areas such as acoustic standards.WORKING GROUPS
4. IQOE Working GroupsFocus on specific topics to plan activities: Acoustic Measurement of Ocean Biodiversity HotspotsArctic Acoustic EnvironmentProvide advice and services related to standards and data: Standardization of Ocean Acoustic ParametersMarine Bioacoustical Standardization Data Management and AccessWG to develop an implementation plan for the GOOS Ocean Sound Essential Ocean Variable

COVID-19 QUIETINGEffects of noise on marine life are usually studied by projecting sounds to animals and observing responses IQOE recognizes that testing whether existing levels of noise may be having adverse effects requires studies on the effect of reducing existing ambient sound levelsReductions in seagoing activities due to COVID-19 created a Quiet Ocean in the spring of 2020IQOE is organizing a global array of listening stations and analyses to study COVID quieting and its effects on marine life Tyack PL, Miksis-Olds J, Ausubel J, Urban ER Jr (2021) Measuring ambient ocean sound during the COVID-19 pandemic, Eos, 102.

IQOE WG is developing Implementation Plan for Ocean Sound Essential Ocean VariableVision/mission/impact Societal Drivers (i.e., what information is needed), Environmental PressuresQuestions that GOOS acoustic measurements should answer worldwideNeeds and requirements What parameters should be measured and how, to provide the information needed to address societal drivers and questions in Section 1 above? Existing Assets for Acoustic ObservationsDescribe acoustic observing and data processing assets worldwide, how existing systems were developed and funded.Standard operating procedures for deployment and maintenance and data management systems for ocean acoustic observations.Funding Governance Describe how existing acoustic networks are governed, who pays for governance, and how existing networks can be linked into a global network, based on examples from other types of observations (e.g., Argo, Data Buoys, Sea-level Network).Steps for GOOS to implement acoustic observations International Ocean Sound EOV Science Team and Coordination Office for observations from hydrophones and particle motion detectorsEstablish an international data center to accept data from international products and serve data and products for the Ocean Sound EOV.Conclusion
17. SummaryIQOE is scheduled to end at the end of 2025.In addition to its tangible achievements, IQOE has created a global community of acousticians and bioacousticians working together to increase understanding about levels and trend of ocean sound, and the effects of ocean sound on marine organisms.To date, about 300 scientists from around the globe have been involved in IQOE and its activities:Initial Open Science Meeting (August 2011): 70IQOE Science Committee Members: 20IQOE WGs and committees: 75IQOE WG on Arctic Acoustic Environments Virtual Meeting: 68IQOE Workshop on Low-Cost Hydrophones: 65The foundation of IQOE activities and the international community created will ensure the legacy of IQOE beyond 2025.
