To sustain life and economic activity, the ocean must be clean. Stakeholders will collaborate to identify pollutants and their sources to the ocean by 2025, remove contaminants from the ocean by 2030 and support society’s transition to a pollutant-minimizing circular economy.
Societies worldwide generate plastic, noise, and harmful chemicals. Whatever the source, these actions on present or increased scales are unsustainable stressors for a clean ocean. The critical gaps in our knowledge of the causes and sources of ocean pollution and its effects must urgently be addressed with interdisciplinary science and transformation of the generated knowledge to society, policy and economy - for the clean ocean we want.
The third Ocean Decade Laboratory "A Clean Ocean" drew participants from 105 countries from all continents. Starting with a common Core Event on 17 November it continued with 29 Satellite Activities, covering aspects and definitions of a clean ocean such as "Improving Plastics Management in Asia Pacific", "Air-Sea Observations for a Clean Ocean" and "Sustainable Management of Plastic Waste". Some Satellite Activities also reminded us that pollution is not just plastic and litter, but also noise. Ships, under-water mining and offshore wind farms are only some of the sources of ocean noise. After two days of Satellite Activities, the Ocean Decade Laboratory concluded with a Wrap-up on 19 November, highlighting the potential for a profitable blue economy with a "Clean Ocean 2030 Manifesto".
If you missed the third Ocean Decade Laboratory, you will find a five-minute documentation below. You can also see the entire Core Event and the Wrap-up here: Core Event and Wrap-up.

During the Core Event, five Breakout Sessions on the topic of "The Quest for Change" were recorded as visual representations. You can find these drawings in the gallery below or watch the Breakout Sessions in their entirety here: Session 1, Session 2, Session 3, Session 4.

Here you do have the chance to rewatch the presented video from the Story of Success: Tubbataha Reef – Jewel of the Sulu Sea.
This event explores how the Integrated Marine Debris Observing System (IMDOS) can strengthen the scientific knowledge on marine litter pollution to support research, innovating solutions, and mitigating actions.
This Activity is an opportunity to discuss how to maintain a Clean Southern Ocean by strengthening links between science, industry & policy in order to develop techniques suitable for polar conditions & activities for solving gaps in knowledge/data.
A practical workshop that will draw on the Plastic Management Index - the first attempt to quantify plastic management practices at a country level - to provide policymakers and stakeholders with tools to improve national plastic management efforts.
The Marine Litter challenge must prompt scientists, governments, industry, environmental groups and citizens to take urgent action and to work together. This webinar aims to strengthen those interactions, contributing to a Joint Strategy.
Opus Whales explores the invisible threat of underwater anthropogenic noise from an artistic slant. A brief experience to empathize with creatures that rely on sound to survive. (Headphones are suggested, but not mandatory.)
This webinar is a general guide to the current implementation of the Stockholm Convention regarding the problem of POPs pollution and prospects of further actions within the framework of the UN Ocean Program.
This Satellite Activity aims to give voice to several Mediterranean experiences of tackling marine litter, looking at best practices between marine litter, its prevention and remediation, and highlighting programs implemented in Mediterranean areas.
3 hypotheses for a clean ocean: 1. Maritime activities can provide enablers for clean ocean science and research, 2.The shipping sector can be stimulated to support a clean ocean, 3.The opposite of a clean ocean will greatly impact shipping.
