Developing a comprehensive portfolio of theoretically sound indicators is fundamental to effective place-based management of coastal ecosystems at a wide range of scales. We reviewed indicator development case studies from seven different social-ecological systems over the first 10 years of the NOAA integrated ecosystem assessment (IEA) program, with the goals of identifying effective strategies and highlighting general principles that would inform future efforts. The IEA framework provided a versatile approach to developing indicators across a diverse range of differently scaled systems and partnerships, guided by organizing principles of screening transparency, iterative review, and an adaptive balance between quantitative evaluation methods and qualitative stakeholder guidance. Information exchange across the broad community of EBM practitioners facilitated progress between systems, chronologically tracking a path that reflected improvements in indicator development methods (especially for social indicators) and a growing focus on multisector EBM in smaller coastal communities. Most projects adopted innovative visual imagery to engage partners and stakeholders, which built trust and communication while enhancing the spectrum of indicators. Using guidance from the lessons above, future indicator development efforts will be better prepared to confront the recurring, transdisciplinary challenges of managing integrated social-ecological systems.

Science-based natural resource management is necessary for agencies to effectively meet their goals and mandates. However, this scientific basis needs to be advanced and evolved with ecosystems experiencing unprecedented events that challenge conventional management frameworks. Effectively managing marine resources and achieving agency missions requires more than meeting independent mandates and managing individual resources as chronic stressors overwhelm conventional management frameworks. Global science organizations are transitioning to interdisciplinary and holistic research to integrate human well-being as a key outcome. The United States' principal federal agency tasked with managing coastal and marine ecosystems is the National Oceanic and Atmospheric Administration (NOAA). NOAA's vision is "healthy ecosystems, communities and economies that are resilient in the face of change". NOAA adopted the Integrated Ecosystem Assessment (IEA) approach to conduct the collaborative science necessary for ecosystem-based management. IEAs have been employed for over a decade to develop science, tools, and collaborations that address complex ecosystem challenges and make progress toward NOAA's vision. This paper demonstrates, through case studies, how scientists, stakeholders, and managers build trust and meaningful relationships from the IEA approach. These case studies further demonstrate how the IEA approach can be adapted to various geographic and management scales to build trust with partners and provide the ecosystem science, including social science, required to build resilient coastal ecosystems, communities, and economies.
