Harnessing the Fourth Industrial Revolution for Oceans

The report explores the 'digital ocean'—a convergence of advanced sensors, AI, and biotechnology—to improve the management of marine resources. It identifies key applications for sustainable fishing, pollution prevention, and climate resilience, while warning that these same technologies could accelerate exploitation if not governed by agile, multistakeholder frameworks.

• The 'digital ocean' is characterized by an explosion of data from advanced sensors on satellites, underwater and surface drones, buoys, and fishing nets, which can be processed using AI and machine learning to improve decision-making for ocean managers and fishers.
• Illegal, unreported and unregulated (IUU) fishing accounts for approximately 20% of the global fish catch, resulting in annual losses of $23 billion for governments and legitimate fishers.
• Technological solutions for sustainable fisheries include DNA barcoding for seafood identification, blockchain for supply chain traceability, and biotech innovations to create fish-free feed from methane or insects.
• Ocean pollution is severe, with 8 million tons of trash entering oceans annually and a prediction that plastics will outnumber fish by 2050; the largest dead zone at the mouth of the Mississippi River reached 22,730 square kilometres in 2017.
• Habitat protection can be enhanced through drones for ecosystem restoration, such as planting mangroves, and 'assisted evolution' to breed coral strains more resilient to warming and acidification.
• Ocean wildlife populations have declined by 36% since 1970, with some baleen whale populations down more than 80% and whitetip shark populations declining by an estimated 93% between 1995 and 2010.
• Climate change has caused the oceans to absorb 90% of excess heat produced by humans since 1955, leading to global bleaching events that affected 70% of the world's coral reefs in 2015 and 2016.
• The Fourth Industrial Revolution presents risks where data on fish stocks or protected species could be used by poachers and illegal fishers to increase exploitation efficiency.
• Successful transition to a sustainable ocean economy requires new business models, open-source data sharing through initiatives like the Ocean Data Alliance, and agile governance to replace ossified management regimes.
