This document is a report on ocean health and safety from One Ocean. It includes an agenda with sections on context, findings, global warming and ocean warming, lines in the ocean, sustainable coastlines, and next steps. A summary is provided by James Tremlett from Papua New Guinea, who discusses the successful marine education program of the small NGO Mahonia Na Dari. He emphasizes the need for concrete conservation actions and vigilance regarding laws governing ocean activities, as Papua New Guinea will undergo the world's first industrial deep-sea mining operation. The section on global warming and ocean warming by Professor Tim Naish notes that warming oceans are causing sea level rise and changes around New Zealand, with uncertainty around Antarctic ice melt
