Professional and scientific societies are increasingly engaging in efforts to create a science community that manifests justice, equity, diversity, and inclusion (JEDI). However, progress assessment is challenging, and opportunities for community feedback are limited. During the 2022 Ocean Sciences Meeting, the Oceanography Society (TOS) JEDI committee led an interactive Town Hall to collect feedback from conference participants and TOS membership on three themes: challenges, initiatives, and opportunities related to advancing JEDI in ocean sciences. This Town Hall was preceded by a survey that was administered to the TOS membership. Survey respondents and Town Hall participants provided valuable observations and synthesis on the past, present, and future of JEDI work in ocean sciences. Discussion included both positive efforts and outcomes of JEDI work as well as harmful and ineffective practices. This paper synthesizes feedback received and highlights ways in which the ocean sciences community and professional and scientific societies can advance similar work. Gatekeeping, a system of implicit or explicit cultural and institutional constraints to and requirements for entry into a field, was identified as the most significant challenge to diversifying the ocean sciences. The majority of survey respondents agreed that efforts to broaden participation have been successful, and identified specific initiatives that have been effective, including the development and support of mentorship and training programs and partnerships with minority-serving institutions. Some challenges to advancing JEDI initiatives include targeted recruitment from the most “elite” institutions and “parachute science.” Respondents agreed that professional and scientific societies have an important role to play in advancing JEDI in ocean sciences. Participants discussed strategies to broaden participation, including efforts that can be employed by professional and scientific societies such as regular data collection on demographics, improved information sharing, and stricter codes of conduct at professional meetings. We conclude by summarizing some new TOS-led initiatives that are designed to promote JEDI in ocean sciences and beyond.
