Guidelines for ensuring meaningful engagement of early career researchers in scientific collaborations: recommendations from and for marine and polar scientists

There is an increasing recognition of the importance of involving early career researchers (ECRs) in scientific positions of trust within national and international organizations, collaborative research projects, networks, and working groups. While the inclusion of ECRs in positions traditionally dominated by more established scientists is a welcome development to increase diversity, equity and inclusion in science, ECRs are often brought into different processes without consideration of the differences in career stages and unfamiliarity of newcomers to projects and processes. These challenges are particularly felt by ECRs with multiple disadvantaged statuses or identities (e.g. ECRs from ethnic minorities, the Global South, and those with caring responsibilities). This paper presents ten guidelines prepared as a participatory process of 12 marine and polar science early career networks, aiming to provide a comprehensive framework for various stakeholders involved in the academic and research ecosystem to improve ECR engagement in collaborations and institutional processes. These guidelines are intended to be adaptable to various contexts, ensuring that all those engaging with ECRs can effectively support their development and well-being. By following these guidelines, members of the scientific community and associated organizations can contribute to a nurturing and productive working environment that benefits the entire research community. This, in turn, will contribute to the long-term success of individual researchers, their institutions, and ultimately science itself.
