Description
Summary:Abstract This paper examines a number of specific, practical recommendations to advance knowledge and move towards evidence-based solutions to microplastic (MP) pollution in the Nordic marine environment. The paper approaches the subject of MPs holistically, emphasises the knowledge gaps and challenges in answering pressing questions, discusses the limitations that so far have prevented these questions from being solved, and suggests approaches for answering them. The Nordic context is chosen due to the global importance of its ecosystem that is threatened by MP pollution, exacerbated by climate change. The research questions discussed pick up knowledge gaps identified in attempts to answer the most pressing questions of our time regarding marine MP pollution and are applicable to some or all seas of the Nordic region, from the Baltic and North Seas in the south to the Arctic in the north. The research questions relate to sources, sinks and transport of MPs, and how food webs are potentially impacted in Nordic marine environments. In addition, we point out the relevance for stakeholders expected to use the emerging knowledge. Through this exercise, using concrete examples, we aim to invite discussions on how a concerted effort by the Nordic countries can bring MP research to a higher level of understanding needed to address the MP pollution problem in Nordic marine habitats.
