Early Career Researchers (ECRs) comprise a significant portion of the workforce in polar research communities, yet remain an underutilized resource in many larger international polar research organisations and projects. A key goal of the Association of Polar Early Career Scientists (APECS) is to develop training and career development opportunities for ECRs, and part of that is achieved by integrating ECRs into polar research and coordination activities from the outset. Benefits to organisations and projects who welcome ECRs include gaining unique perspectives from passionate, skilled minds as well as having an active role in training future leaders of these groups. APECS also serves as an institutional partner to support early career involvement to reduce an organisation or project’s organizational risk of working with ECRs given, for example, inherent and relatively unpredictable career transitions. APECS is also uniquely qualified to plan online and in-person training experiences, as evidenced for example through our long-term webinar series, a multitude of workshops and the Polar Prediction School 2018 as part of APPLICATE. This poster will describe opportunities available to ECRs through APECS’ engagement in polar research organisations and in large consortia like the EU Horizon 2020 funded projects APPLICATE, INTERACT, ARICE, and NUNATARYUK. Successful collaborations have relied on engagement with APECS as a partner in order to integrate education, outreach, and training activities within these projects. APECS looks forward to working with other polar research groups to include ECRs through every phase of development.
