In the realm of marine science, engaging with stakeholders (e.g., industry members, policy-makers, managers, NGOs) is an important method applied in many research projects. The Covid-19 pandemic has severely impacted this engagement in two ways. First, social distancing measures forbid most face-to-face participatory activities originally envisioned in projects. Second, the restrictions have caused hardships for the stakeholders being engaged by these projects. We assessed the impact of Covid-19 on stakeholder engagement activities in ongoing EU marine science projects by posing the following questions: What problems has Covid-19 caused for the workflow and outcomes of current research projects, (ii) how have scientists responsible for stakeholder engagement coped with the situation, and (iii) if alternative stakeholder activities were implemented, how have these been evaluated? Our survey was conducted nearly 2 months after the onset of Covid-19 lockdowns. It addressed researchers who engage with stakeholders in EU projects and delivers insights into the practical implications of Covid-19 for stakeholder engagement and the measures taken to tackle this challenge. The paper highlights the impacts of the pandemic on stakeholder engagement in marine science, outlines current coping strategies in different EU projects, and recommends seven practical actions to promote and maintain meaningful exchange with stakeholders in times of social distancing and lockdowns.
