Ocean Decade Vision 2030 White Papers – Challenge 1: Understand And Beat Marine Pollution.

By 2030, the success of Ocean Decade Challenge No.1 ‘Understand and Beat Marine Pollution’ will be demonstrated by the generation of scientifically sound data enabling a holistic understanding of the extent and impact of pollution across the land-ocean continuum, thereby supporting the achievement of a cleaner and healthier ocean where all ecosystems and their inhabitants thrive free from the impacts of marine pollution, allowing for their full functioning and service provision. This success will be based on completion of a comprehensive review of all available evidence about marine pollution, including an analysis of data gaps and the development and implementation of strategies for filling those gaps, as well as a comprehensive analysis of solutions for addressing and preventing the negative effects of marine pollution. Achieving this success will require knitting together existing and new data sets using AI and other technologies, identifying priority pollutants and areas for action, and providing globally consistent monitoring, data collection, storage and sharing protocols. Success will further be demonstrated through the establishment of new connections and partnerships among users across the public - private spectrum that lead to the funding, development and implementation of new technologies and projects aimed at monitoring, controlling, reducing, and/or mitigating marine pollution from any source, including the creation and sustainability of a global network of strategically positioned sentinel stations and regional laboratory hubs for sustained, long-term monitoring of marine pollution. Success will include fulfilment of the following critical knowledge gaps: • a comprehensive and holistic understanding of the impacts of priority pollutants (e.g., pollutants found or expected to emerge in high concentrations, or with high toxicity, or with significant adverse effects on biota or human health) across the land to ocean continuum; • a better understanding of the sources, sinks, fate and impacts of all pollutants, including the pollutants of emerging concern; • improved knowledge on the distribution and impacts of marine pollution, particularly in the Global South and deep ocean waters, which currently represent the largest geographical gaps. and the following priority datasets gaps: • long-term time series of marine pollutants; • baseline and toxicity data of pollutants across the land-ocean continuum; • data on the impacts of the co-occurrence of multiple pollutants; • data on the effects of climate change on the toxicity, bioavailability and impacts of multiple co-existent pollutants. • It will include development of: • a global network of strategically positioned sentinel stations for continuous, long-term monitoring; • cost-effective, real-time monitoring systems and technologies for tracking pollutant sources, distribution, and transfers across the land-ocean continuum; • a global network of regional laboratory hubs focused on generating high-quality data, promoting capacity building and facilitating technology transfer; • training programs on harmonized protocols for the acquisition, reporting and recording of quality-controlled data on marine pollution; • environmentally robust new technologies and processes for the control and mitigation of marine pollution.
