ClearWhy sampling season and location matter for monitoring micro and mesoplastics on the beach
Researchers analyzed microplastic pollution across 11 marine beaches in Latvia over four seasons from autumn 2022 to summer 2023, demonstrating how sampling season and location significantly influence measured pollution levels in the Baltic Sea region due to seasonal weather patterns and local hydrodynamics.
Why sampling season and location matter for monitoring micro and mesoplastics on the beach
Researchers examined microplastic and mesoplastic pollution across 11 marine beaches in Latvia over four seasons from autumn 2022 to summer 2023, investigating how sampling season and beach location affect measured contamination levels. The study found significant spatial and temporal variability in beach microplastic concentrations, demonstrating that both season and location are critical variables that must be accounted for in monitoring programme design to produce meaningful and comparable pollution assessments.
The baseline for micro- and mesoplastic pollution in open Baltic Sea and Gulf of Riga beach
Researchers established a baseline for microplastic and mesoplastic pollution along 24 beaches on the Latvian coastline of the Baltic Sea, using data collected with the help of up to 250 citizen science volunteers. They found that beaches on the open Baltic Sea contained more plastic particles than those in the semi-enclosed Gulf of Riga. The study analyzed wave patterns, currents, and tourism intensity as factors driving pollution distribution and highlights citizen science as a valuable tool for large-scale microplastic monitoring.
Micro- and mesoplastic pollution along the beaches in the open Baltic Sea and Gulf of Riga
Researchers conducted a baseline assessment of micro- and mesoplastic pollution along 24 beaches of the Latvian Baltic coastline with 250 citizen science volunteers, finding lower MP concentrations in the semi-closed Gulf of Riga (0.10 particles/kg dry sand) than in the open Baltic Sea (0.16 particles/kg dry sand).
Spatiotemporal Variability of Microplastics in the Eastern Baltic Sea
Researchers documented spatiotemporal variability of microplastics in the eastern Baltic Sea over five years, finding concentrations ranging from 0.01 to 2.45 particles per cubic meter with patterns linked to proximity to urban areas and riverine inputs.
Microplastic concentrations in beach sediments along the German Baltic coast
Researchers measured microplastic contamination on beaches along the German Baltic coast near river estuaries and tracked seasonal variation over several months, finding contamination at all sites. The study highlights that river mouths are hotspots for microplastic deposition on coastal beaches.
Spatio-temporal variability in the abundance and composition of beach litter and microplastics along the Baltic Sea coast of Schleswig-Holstein, Germany
Beach litter and microplastics (20-5000 microns) were co-assessed along the Baltic Sea coast of Schleswig-Holstein in spring and autumn 2018, finding no correlation between macro and microplastic abundances, with a median of 2 microplastic particles per 500 g dry sediment and six polymer types identified.
Factors influencing the spatial and temporal distribution of microplastics at the sea surface – A year-long monitoring case study from the urban Kiel Fjord, southwest Baltic Sea
Researchers conducted a year-long monthly survey of microplastic abundance at eight sites within and around Kiel Fjord in the Baltic Sea, finding an overall low and stable load of 0.04 particles per square meter compared to other urban coastal areas. No strong relationship was found between microplastic abundance and weather parameters, though unusually high counts consistently followed rainfall and snowmelt events linked to storm drain inputs.
The occurrence and sources of microplastics to Arctic and sub-Arctic beaches: human influence on local microplastic hotspots
Researchers characterized microplastic occurrence and sources at Arctic and sub-Arctic beaches, finding that proximity to human settlements creates local hotspots, while more remote beaches receive microplastics primarily through long-range oceanic transport.
Abundance, Morphology and Diversity of Microplastics on Beaches in Northern Ireland
Researchers assessed microplastic abundance, morphology, color, and diversity at six beaches along Northern Ireland's north coast during summer and winter sampling, evaluating how anthropogenic pressures and seasonal transportation vectors influence microplastic concentration and composition.
Plastic contamination of sandy beaches along the southern Baltic – a one season field survey results
Researchers surveyed microplastic and macroplastic contamination along the Polish Baltic Sea coast, finding microplastic concentrations of 118–1,382 pieces/kg in beach sand and 0.61–2.76 pieces/dm3 in coastal waters, with sub-1 mm blue fibers dominating across all sites and suggesting a common fibrous source throughout the Polish coastal zone.

Spatiotemporal distribution of microplastic debris in the surface beach sediment of the southeastern coast of bangladesh
Researchers characterized spatiotemporal distribution of microplastic debris in beach sediments along approximately 240 kilometers of Bangladesh's southeastern coastline across seven beaches, comparing monsoon and winter seasons to assess seasonal variability. The study analyzed MP abundance, polymer type, shape, size, and color to provide the first comprehensive regional baseline for this heavily populated coastal area.
Occurrence and spatial distribution of microplastics in the surface waters of the Baltic Sea and the Gulf of Riga
Microplastic abundance and composition were compared between the Gulf of Riga and the Eastern Gotland Basin of the Baltic Sea, with higher concentrations in the Gulf of Riga near river mouths and urban coasts, and polypropylene and polyethylene dominating the polymer composition at most sites.
Sources and fate of microplastics in marine and beach sediments of the Southern Baltic Sea—a preliminary study
Researchers investigated microplastic sources and distribution in marine and beach sediments of the southern Baltic Sea — one of the most polluted regional seas — using density extraction and FT-IR identification. The study found widespread contamination with significant variability tied to local sources and hydrodynamic transport patterns.
Changes in (micro and macro) plastic pollution in the sediment of three sandy beaches in the Eastern Mediterranean Sea, in relation to seasonality, beach use and granulometry
Researchers measured plastic and microplastic pollution in sediment from three Mediterranean beaches across seasons, finding that smaller microplastics accumulate at the backshore while larger items concentrate near the waterline. Seasonal patterns and beach use intensity affected plastic abundance, with implications for beach management and cleanup strategies.
