Surfing for Science

Vast amounts of microplastics have been found floating on the surface of subtropical oceanic gyres. However, the distribution of floating plastic in the ocean is still poorly constrained, and there is a lack of information from coastlines. The reason behind is the general use of trawls towed by research vessels to collect scientific samples. We have designed a net trawl to collect samples in the nearshore from SUPs, kayaks, and rowing boats. Coordinated by the University of Barcelona and the Spanish delegation of Surfrider Europe, several associations have been acquiring scientific samples since 2019. Our results reveal that pollution by microplastics in the nearshore is even higher than that found in the subtropical gyres, and that breakdown of plastics occur in the nearshore. The project has represented a paradigm shift in microplastic research, and we have proven that citizen science is a powerful tool in plastic research as it provides scientifically meaningful results while stimulating citizen engagement.
