The International Quiet Ocean Experiment (IQOE) developed under the auspices of the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Ocean (POGO), is convening a virtual workshop to share information on current solutions and new developments in low-cost self-contained underwater acoustic recording systems, and to discuss possible ways forward to make these systems available, to be deployed at a global scale in a variety of different environments and ecosystems (from the open ocean to shallow coastal areas and from low to high latitudes), making consistent and calibrated measurements at higher temporal and spatial resolutions, making data freely available on-line for use by scientists and policy makers.  

For this workshop, we invite scientists and engineers involved in passive acoustic measurements and technological development to present their work and discuss the challenges and opportunities offered by existing and novel self-contained underwater acoustic recording systems.

We are particularly interested in new systems that fit the following criteria:
  • Manufacturing cost of around $50-$200
  • Can be calibrated by user and/or calibrated by the manufacturer at a reasonable cost
  • Data processing can be achieved without specialist knowledge, supported by manuals, tutorials and/or training courses.
The workshop will discuss optimal combinations of precision and accuracy, target frequency ranges (e.g., for ambient sound vs bioacoustics), and issues regarding time-stamping, in order to meet the needs of user communities as well as the cost goals and other parameters described above.

The workshop welcomes the participation of potential developers and users of low-cost systems, operators of observing systems or platforms with an interest in adding acoustic capabilities to these, students and early-career scientists. The workshop will run for 2 hours and will be held twice (at different times) to maximise participation from different parts of the world. 

Call for contributions
We invite abstracts for short oral presentations, most of which will be allocated 3-5 min slots. Depending on the number of abstracts received some of the presentations may need to be pre-recorded and made available to the participants in advance.

Abstracts should be no more than 2,000 characters including spaces.

Please submit your abstract using this registration form by 23:59 UTC on 24 November 2021. The book of abstracts will be published on the IQOE website, and the workshop discussions may also be synthesised into a joint publication as an outcome of the workshop.
