Fundamental Questions

Underlying the IQOE are five fundamental questions:

  1. How have human activities affected the global ocean soundscape compared with natural
    changes over geologic time?
  2. What are the current levels and distribution of anthropogenic sound in the ocean?
  3. What are the trends in anthropogenic sound levels across the global ocean?
  4. What are the current effects of anthropogenic sound on important marine animal populations?
  5. What are the potential future effects of sound on marine life?

These questions will be addressed within four IQOE Themes. Questions 1-3 will be addressed by Theme 1, and Questions 4 and 5 will be addressed by Theme 2. Theme 2 will build on Theme 1 and Theme 3 will build on both Themes 1 and 2. The three themes are divided into key questions and research approaches to each of these questions. Theme 1 will primarily be addressed by ocean acousticians and Theme 2 by marine biologists, but there will need to be an unprecedented level of cooperation between these two communities to ensure the success of the IQOE.

Status: The IQOE Science Plan has been reviewed and approved by the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Oceans (POGO), and is available here.

Funding has been obtained to begin initial implementation activities. An IQOE Science Committee has been formed and met for the second time in London, UK on 27-28 January 2017.

SCOR and POGO staff members will assist project scientists with implementation.

Next Steps: Additional funding is being sought, including for an international project office.
