Working Group 42: Indicators of Marine Plastic Pollution
Motivation and Goals:
Marine debris is increasingly recognized as a threat to biota in the ocean, and especially North Pacific and its marginal seas are reported as ‘hot spots’ for its abundance. However, organismal and non-organismal indicators, which are consistently available across the North Pacific region, for plastic pollution status and trend and ecological impacts are not established.
Terms of Reference
  1. To review pollution (e.g. abundance, distribution, composition, and potential impacts) across different size categories in the North Pacific and its marginal seas;
  2. To identify multiple organismal and non-organismal indicators of plastic pollution and its environmental impacts including associated chemicals in the North Pacific and its marginal seas;
  3. To recommend guidelines for monitoring environmental indicators and a target improvement goal for the established indicators;
  4. To convene a topic session and/or workshop on environmental indicators and impacts of plastic pollution and coordinate a special issue in an international peer-reviewed journal;
  5. Contribute to FUTURE by publishing a final report summarizing results of the Working Group deliberations.
