In order to protect and manage marine species and habitats, there is an immediate need for the creation of robust evidence-based methods. Therefore, there is a need to undertake marine research projects that are developed and implemented collaboratively, strategically, and at a sufficient scale. NorTrack will leverage ongoing acoustic tracking projects across the Northeast Atlantic (NEA) region and Europe by expanding efforts to connect initiatives on species-based biodiversity management while developing data management plans and networking channels to deliver data to national and international governing bodies. Coordinating aquatic animal tracking efforts at a scale that will be usable to make progress on international marine management and planning is a major step towards an operational European Tracking Network (ETN) that contributes to major European biodiversity initiatives, conservation, and policy. Acoustic telemetry has vast potential when it comes to understanding the behaviours of mobile marine species both within and across territorial waters. Acoustic telemetry refers to the use of transmitters or “tags” attached to target species that emit sound pulses that are heard by underwater receivers. This system allows researchers to track target species as they move through networks or across lines of receivers. The more complex the network of receivers, the more robust the dataset becomes. Knowledge of how key species use marine space allows for the creation of tailored strategies for protection, management, and development, which take into account how marine species use critical habitats. Recent efforts to develop aquatic telemetry networks have been at local or bilateral levels in Europe while larger networks in North America and Australia have established and are providing critical data relevant to management. The NorTrack project will support and enhance the existing and planned a basin-wide network of acoustic receivers in the NEA and across European seas, which is the next step towards a cohesive and integrated European-wide telemetry network.
