AbstractOperating an ocean observing system in a region as vast and diverse as the Exclusive Economic Zone of the U.S. Pacific Islands poses common and unique challenges that require tailored solutions. In order to address stakeholder needs for ocean data and information
in a cost-effective and impactful manner, the Pacific Islands Ocean Observing System (PacIOOS) functions under a framework of stakeholder-driven priority setting. This strategy employs an innovative categorization of stakeholders into four general categories for the purpose of delineating
levels of engagement: (a) data super users, (b) industry and natural resource managers, (c) informed public ocean users, and (d) the general public. Stakeholder needs are continuously gathered through many avenues, including staff dedicated to communications and engagement throughout the region
and a higher-level governance framework composed of signatory partners. Principles of degree of need and potential for positive impact are utilized for prioritization. Although PacIOOS cannot engage with all stakeholders in the region, the approach taken to identify, engage, and respond to
stakeholders serves as an effective and efficient method to ensure that both specific ocean stakeholders and stakeholders, writ large, benefit from the resources and efforts expended to advance ocean observing in the region. Two case studies from separate geographies and components of the
PacIOOS program illustrate the value of this stakeholder-driven approach to users in the region. This approach may serve as a model for how to effectively address stakeholder needs and improve decision making through a regional ocean observing system.
