First observation on neustonic plastics in waters off NW Spain (spring 2013 and 2014)
AI summary Read the abstract
Researchers conducted the first survey of plastic particles in surface waters off the northwest coast of Spain over two years, finding plastic microparticles at 95% of sampling stations. The baseline data will help implement the EU Marine Strategy Framework Directive's monitoring requirements for marine litter in this region.
This paper examines the presence and distribution of plastic particles in waters off the NW Spanish Atlantic coast. A pilot sampling program was initiated in 2013 to study the presence of plastic particles in surface waters. A total of 41 neuston samples were collected using a manta trawl fitted with a 333 μm mesh (21 samples in 2013 and 20 samples in 2014). Several types of plastic particles were observed in 95% of the stations. A total of 1463 plastic microparticles (<5 mm; mps) and 208 mesoparticles (>5 mm and <20 mm; MPS) were counted. Average concentrations recorded were 0.034 ± 0.032 and 0.176 ± 0.278 mps m(-2) and 0.005 ± 0.005 and 0.028 ± 0.043 MPS m(-2), respectively for 2013 and 2014. Results on this emerging topic are discussed as a preliminary step towards implementation of the Marine Strategy Framework Directive in the region. Harmonization of protocols for determination of plastic particles is urgently needed in order to compare results between regions and to ensure coherence in the implementation of the MSFD. This aspect is also important at a worldwide scale.

The coastal waters of the south-east Bay of Biscay a dead-end for neustonic plastics
AI summary Read the abstract
Researchers collected neustonic surface samples along the coastal waters of the south-east Bay of Biscay from 2017 to 2020, finding an average plastic abundance of 739,395 items/km2 with microplastics comprising 93% of items, and demonstrating that French coastal waters had five times higher plastic concentrations than Spanish coasts, consistent with numerical model predictions of this region as a convergence zone.
Monitoring microplastics in coastal waters of a biosphere reserve: a case study in Menorca (Spain)
AI summary Read the abstract
Researchers sampled surface waters at 90 sites around the UNESCO-protected island of Menorca, Spain, finding microplastics in every single sample at consistent levels across two years. Fiber-type plastics dominated everywhere except the commercial port, where packaging foam made up nearly half of all particles — pointing to shipping activity as a local source. The study establishes a harmonized monitoring baseline useful for tracking whether EU marine pollution policies are actually working.
