The International Council for the Exploration of the Sea (ICES) and ICES Journal of Marine Science (ICES JMS) strive to advance marine science by publishing Symposium Issues (SIs). SIs are a series of coordinated contributions that were presented at an ICES co-sponsored symposium. These collected articles are introduced by a synthetic overview of the symposium objectives and its outcomes.

ICES now welcomes submission on the following themes:

1. Monitoring and assessment of plastic pollution in the Arctic.
2. Methodological developments to determine macro, micro and nano plastics.
3. Sources and transport of plastic in the Arctic and sub-Arctic.
4. Impacts of marine litter in the Arctic (environmental, economic and social).
5. Arctic challenges and solutions for improved waste management.
6. Tackling plastic pollution: international collaboration, policies, best practices and novel developments from around the world.
