The ocean plays a critical role in supporting human well-being, from providing food, livelihoods and recreational opportunities to regulating the global climate. Sustainable management aimed at maintaining the flow of a broad range of benefits from the ocean requires a comprehensive and quantitative method to measure and monitor the health of coupled human–ocean systems. We created an index comprising ten diverse public goals for a healthy coupled human–ocean system and calculated the index for every coastal country. Globally, the overall index score was 60 out of 100 (range 36–86), with developed countries generally performing better than developing countries, but with notable exceptions. Only 5% of countries scored higher than 70, whereas 32% scored lower than 50. The index provides a powerful tool to raise public awareness, direct resource management, improve policy and prioritize scientific research.

COMPASS shares a decade of experience in helping scientists become effective leaders by navigating a path from outreach to meaningful engagement with journalists and policymakers.

As human impacts cause ecosystem-wide changes in the oceans, the need to protect and restore marine resources has led to increasing calls for and establishment of marine reserves. Scientific information about marine reserves has multiplied over the last decade, providing useful knowledge about this tool for resource users, managers, policy makers, and the general public. This information must be conveyed to nonscientists in a nontechnical, credible, and neutral format, but most scientists are not trained to communicate in this style or to develop effective strategies for sharing their scientific knowledge. Here, we present a case study from California, in which communicating scientific information during the process to establish marine reserves in the Channel Islands and along the California mainland coast expanded into an international communication effort. We discuss how to develop a strategy for communicating marine reserve science to diverse audiences and highlight the influence that effective science communication can have in discussions about marine management.marine protected areas | science education | public outreach | communication strategy | California

In this commentary we are concerned with what mainstream science communication has neglected through cultural narrowness and ambient racism: other practitioners, missing audiences, unvalued knowledge, unrecognised practices. We explore examples from First Nations Peoples in the lands now known as Australia, from Griots in West Africa and from People's Science Movements in India to help us reimagine science communication. To develop meaningfully inclusive approaches to science communication, we argue there is an urgent need for the ‘mainstream’ to recognise, value and learn from science communication practices that are all too often seen as at ‘the margins’ of this field.

The role of scientists in social media and its impact on their careers are not fully explored.  While policies and best practices are still fluid, it is concerning that discourse is often based on little to no data, and some arguments directly contradict the available data.  Here, we consider the relevant but subjective questions about social media for science outreach (SOSM), specifically: (1) Does a public relations nightmare exist for science?; (2) Why (or why aren’t) scientists engaging in social media?; (3) Are scientists using social media well?; and (4) Will social media benefit a scientist’s career? We call for the scientific community to create tangible plans that value, measure, and help manage scientists’ social media engagement.
