GOOS invites ocean-observing community representatives to serve on the OceanObs’29 Program Committee, a leadership opportunity to shape the vision and outcomes of this premier decadal conference. Held every decade, the OceanObs conference series brings together the global ocean-observing community to evaluate progress, address emerging issues, and guide future ocean observation efforts. The organizers seek a broad range of ocean knowledge-holders, spanning science, engineering, policy, and industry, including classical experts, Early Career Professionals (ECPs), indigenous representatives, and thought leaders. Your contributions will help shape the conference's agenda, structure, and outcomes, making a meaningful impact on the next decade of global ocean observing. Deadline: 31 May 2025
