Advancing Ocean Sustainability for Climate-Resilient Change <p id="p1">The United Nations (UN) Decade of Ocean Science for Sustainable Development spans from 2021 to 2030 as a global call to action for marine scientists and Early Career Ocean Professionals (ECOPs) to collaboratively create, implement, and communicate science-based solutions to the critical challenges faced by our shared Ocean. The Decade integrates science, policy, and international engagement of a broad base of civil society stakeholders through interdisciplinary research challenges aimed at establishing sustainable marine practices to confront issues related to climate change. This chapter presents a synopsis of the UN-led initiatives that culminated in the launch of the Ocean Decade and describes the global vision articulated in the UN 2030 Agenda for Sustainable Development, focusing on Sustainable Development Goal 14, <em><italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Life Below Water</italic></em>. The critical need for multidisciplinary Ocean research and innovation, collaborative sharing of findings grounded in data, and recommendations for global mitigation and policy development are discussed. The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) is recognized as an exemplary Ocean Decade endorsed action, offering collaborative research experiences and opportunities to contribute to data-driven recommendations influencing policy development on an international scale. Enhancing Ocean literacy through the dissemination of precise, data-driven information is essential for advancing Ocean sustainability for climate-resilient change and safe-guarding the well-being of our Ocean.</p>

#SundayRead: #OpenAccess chapter on the UN #OceanDecade, SDG 14, and collaborative ocean science. Highlights endorsed action GO-SHIP and emphasises the importance of #OceanLiteracy in advancing climate-resilient policy and sustainability.

"It’s Not Just One Place I’ve Fallen in Love With": A Participatory Place-Based Approach to Mapping Heritage | Journal of Maritime Archaeology Traditional Cultural Places (TCPs) are historic properties recognized for their cultural significance. Cultural value is determined by living communities and is not dependent on the presence of human-made or human-modified site features. Although eligible for consideration in federal decision-making, TCPs are often absent from state and federal heritage inventories due to challenges in their identification. Given the relationship between people and place, community-based inventory efforts offer opportunities to both document this heritage and support longer-term relationship building. Using an interdisciplinary methodology, we held participatory place-based mapping workshops in Guam and the Commonwealth of the Northern Mariana Islands to document TCPs and maritime archaeological sites. While ultimately successful, the workshops and our shared experiences were shaped by political tensions in the U.S. Pacific Island territories. This paper shares preliminary results on the use of participatory geographic information systems to inventory heritage, including TCPs. Our experiences, and those of our collaborators, are further contextualized within broader themes of Pacific militarization and critical minerals mining.
