(Chiba et al. doi.org/10.1016/j.marpol.2018.03.022)
The data tell… plastics are ubiquitous
Single-use plastics are ubiquitous (80-90% of plastic debris).
Ratio of plastics increases in deep-sea(~ 80%)
Plastic is the most abundant among debris

2. Toward the implementation of globally integrated marine debris observation system
Proposal of the Integrated Marine Observation System (IMDOS) September 2019
RecommendationTo answer scientific questions and societal demands• Establish global observing & information system to evaluate sources/sinks,
abundance, trends, risks and the efficiency of reduction measures, and to get the problem under control
• Achieve understanding of the issues of marine debris through development of efficient in situ observation technology, remote sensors, models and monitoring strategies, involving citizen scientists when possible
• Ensure an integrated, standardized and harmonized collaborative network, using commonly accepted methods & definitions.

Marin Debris Working Group agenda (tentative)
• Global frameworks for selecting priority indicators and variables for monitoring(from global observation to development of SDG 14.1.1. Indicator: marine plastics density)
• Towards standard sampling protocols• Best practices for remote sensing of marine debris• Best practices for modelling• Best practices for citizen science monitoring• Global Platform - how does it work?
