Dataset Overview | National Centers for Environmental Information (NCEI)

Floating microplastics abundance in open and coastal waters of the Eastern Mediterranean Sea (Adriatic, Aegean, Ionian, and Levantine Seas) from 2014-10-09 to 2020-02-10 (NCEI Accession 0259524)

Preview graphic

This study estimated the load of floating microplastics (i.e. plastics less than 5mm, reported in unit of pieces/m^3) in the Eastern Mediterranean Sea (Adriatic, Aegean, Ionian, and Levantine Seas) from 2014-10-09 to 2020-02-10. Data was collected using manta net. This dataset contains the results from all 76 net tows, in a spreadsheet format. Tows were conducted for 15–30 min at an average cruising speed of <2 knots.

Processing Steps	Parameter or Variable: MICROPLASTIC CONCENTRATION (measured); Units: pieces/m3; Observation Category: in situ; Sampling Instrument: Manta net; Sampling and Analyzing Method: Samples of sea surface water were collected for microplastics investigation during 11 sampling campaigns from 2014 to 2020. The start and end sampling positions were obtained either from the vessel’s or from a portable Global Positioning System (GPS). Sea surface microplastics were collected using a manta net with mesh size of 330 µm. The manta net was towed from the side of the vessel and beyond the vessel’s wake. Tows were conducted for 15–30 min at an average cruising speed of <2 knots. At the end of each tow, the net was washed in order to gather all particles in the cod end. In order to avoid sample contamination on board, immediately after sampling, the cod net was transferred into a glass jar and kept frozen until analysis in the laboratory. After thawing, the samples were sieved through a stack of metallic sieves (1 mm and 300 µm), to facilitate the separation of organic material, especially in organic rich samples. In case of presence of large natural organic items (seaweed, branches, and leaves) these were thoroughly washed with deionized water above the stack of sieves to collect all microplastics adhered onto them. Then the two fractions were dried at 40℃. Microplastics were visually identified under a stereomicroscope.; Data Quality Method: ATR-FTIR spectroscopy was used to confirm the microplastics collected. ATR-FTIR analysis was done in 12% of the total particles counted..
