The focus of this year’s COMPASS Annual Webinar was IMPACT & LEGACY. The event was held on 2nd and 3rd November 2021 and a packed day of presentations and panel discussions was attended by a wide range of stakeholders. The topics covered reflected the achievements of the research teams across the project with a focus on oceanography, data management, model development and specific protected animals such as of cetaceans and salmonids. One of the key issues discussed at the event was the legacy of COMPASS and how it can encourage support and continuity for both the observational programmes and the outputs of the project. This will be continued a focus in the final year of this project, which completes in September 2022.
