Event Description:
The Conservation of Arctic Flora and Fauna (CAFF) initiated a pan-Arctic database of passive acoustic monitoring data holders in 2019. The initial results of this showed that there have been many tens of hydrophone deployments throughout the Arctic (with the exception being in Russian Federation waters). Although incomplete at the time, this effort made it clear that by collaborating internationally, an Arctic Acoustic Observing Network might be established. This network has the potential to provide semi-pan Arctic marine mammal distributions including endemic Arctic species but also acoustically active subarctic species. Passive acoustic monitoring has the advantage of providing year-round data over a broad range of frequencies and spatial scales. Such data can be used to understand changes in the phenologies of Arctic endemic species as well as document the potential borealization of the Arctic. The overall goal of this session is to bring together data holders to establish an Arctic Acoustic Observing Network. To this end, we will locate gaps in our coverage and look for ways to fill those gaps, and identify other partners in the proposed observing network. We will introduce the AWI’s Open Portal to Underwater Soundscapes as a means for standardizing data integration and analysis.
