Practical Evaluation of the Effectiveness of Different Samplers for Microplastic Analysis in Seafloor Sediments
Summary
Researchers compared Multicorer and Van Veen Grab samplers for microplastic analysis in seafloor sediments from the western Black Sea shelf, finding that the Van Veen Grab likely underestimates microplastic concentrations due to disturbance of the upper sediment layer where microplastics accumulate, and recommending harmonisation of sampling methods for FAIR-data repositories.
Summary The paper presents a comparison of the Multicorer and Van Veen Grab samplers in assessing seafloor sediments to analyze the quantity and distribution of microplastics on the seabed. The results from the western Black Sea shelf indicate that Van Veen Grab sampling may underestimate microplastic concentrations compared to the Multicorer. This discrepancy is likely due to the disturbance or loss of the upper sediment layer, where microplastics tend to accumulate. To ensure consistency in FAIR-data repositories, harmonization of microplastic research data obtained using different sampling methods is necessary.

Results of Experimental Research Comparing the Efficiency of Marine Samplers in Researching the Content of Microplastic in Bottom Sediment
Researchers compared the efficiency of two marine sampling devices — a multicorer and a bottom scoop — for collecting microplastics from bottom sediments in the western Black Sea during a 2022 expedition conducted under the DOORS international project. The study generated new comparative data on sampling quality and the potential of each device for assessing plastic pollution in seafloor sediments.
Global mapping for the occurrence of all-sized microplastics in seafloor sediments
Researchers compiled global seafloor microplastic data from 155 marine sediment samples including detailed sampling metadata and abundance measurements for 20 microplastic categories, providing foundational data for understanding the distribution and uncertainty of microplastic contamination on the seafloor.
Microplastics in Baltic bottom sediments: Quantification procedures and first results
Researchers developed modified procedures for quantifying microplastics in Baltic Sea bottom sediments, addressing limitations in the standard NOAA methods — particularly the underestimation of fiber counts. The proposed improvements offer a more reliable approach for monitoring sediment contamination in this heavily polluted regional sea.
Microplastic pollution in the North-east Atlantic Ocean surface water: How the sampling approach influences the extent of the issue
Researchers compared two different sampling methods for measuring microplastic pollution in the open North-east Atlantic Ocean and found that results varied dramatically depending on the technique used. The grab sampling method captured significantly more small particles than the traditional Manta trawl approach. The study demonstrates that the choice of sampling method can fundamentally change our understanding of how much microplastic pollution exists in ocean waters.
