Acoustics on the roadmap for an Integrated Arctic Observing System

The current status of the ocean in situ observing system in the Arctic are addressed in the EU funded Integrated Arctic Observation System (INTAROS). We describe how multipurpose acoustic systems can contribute to fill gaps and to establish an optimized Pan Arctic Ocean Observing System. A brief presentation of the steps from a series of experiments in the Eastern Arctic towards the upcoming pan-arctic Coordinated Arctic Acoustic Thermometry Experiment are given. How we can use this experience to ensure that multipurpose Arctic observation system will get on in roadmap for an Arctic Observing System? Any sustainable ocean observing systems in the Arctic depend on long-term funding, and that funding mechanisms other than research programs should be used for this. To achieve this, we need to engage with stakeholder groups outside the scientific community. How can this be done?
