Subsurface microplastics concentration in the Eurasian Arctic (Barents, Kara, Laptev and East-Siberian Seas) collected aboard R/V Akademik Mstislav Keldysh from 2019-09-18 to 2019-10-21 (NCEI Accession 0277532)

Preview graphic

This study estimated the concentration of subsurface microplastics (i.e. plastics measuring less than 5mm, reported in unit of pieces/m3) in the Eurasian Arctic (Barents, Kara, Laptev and East-Siberian Seas) from 2019-09-18 to 2019-10-21. Microplastics data were collected aboard R/V Akademik Mstislav Keldysh using its underway pump-through system with an intake located at a depth of 3m. This dataset contains the results from all 60 subsurface water samples, in a spreadsheet format.

Processing Steps	Parameter or Variable: microplastic concentration (measured); Units: pieces/m3; Observation Category: in situ; Sampling Instrument: Intake seawater pump; Sampling and Analyzing Method: 60 subsurface seawater samples were collected by a ship-board underway pump-through system with an intake located at a depth of 3m on the right side of the vessel. The water flow within the pump-through system was provided by a 900-watt onboard pump (Metabo). The system was equipped by a thermosalinograph (SBE 21 SeaCAT) that was continuously recording salinity and temperature of flowing subsurface seawater. In order to perform microplastic sampling, flowing subsurface seawater was passed under pressure through two stainless steel meshes (1.5 mm and 100 μm pore size) within the filtration system, which consisted of two sequentially established first step water appliance protective systems and food grade PVC pipes. A flow meter Decast Metronic BKCM-15 in the system provided accurate registration of water volume for each sample, which varied from 2 to 5m3 per sample. After every sampling period, collected material was rinsed from the filtration system by backward water flow within the system and filtered onto a stainless-steel mesh filters (Ø 25 mm, pore size 80 μm) using a filter holder attached directly to the sampling system to avoid contamination from the air. For this purpose, 25mm filter holders were attached to outlets of the valve of the filtration system. Filters were sealed in glass jars pre-rinsed using pre-filtered (0.45 μm) Milli-Q water. These jars were stored until the analysis in the onshore clean laboratory. In the laboratory, the samples were processed to remove organic matter using an optimized protocol with 10% KOH in the same jars where the filters were stored. The processed samples were filtered onto 47mm GF/A papers with 1.6 μm pore size. The filter with material was immediately transferred to a petri dish and covered for drying and further analysis. All particles from subsurface samples were analyzed using a combination of visual inspection and chemical identification of polymeric composition via spectroscopy methods. Subsurface samples on GF/A filter papers were visually examined under a dissecting microscope Nikon SMZ745T fitted with an Infinity 1-3C camera and the associated Infinity Analyze software. Photographs of all potential microplastics were recorded, size (mm) and surface area (mm2) were measured using Image software, and their morphology (fibers or fragments) was described. Visual identification followed where fibers are distinguished from fragments based on the length to width composition. All selected particles from each sample were subjected to further chemical characterization using μFT-IR analysis on PerkinElmer Spotlight 400 FTIR (transmission micro-FTIR with DCC).; Data Quality Method: To mitigate sample contamination, a number of procedural steps were introduced. All equipment and glass jars were rinsed with prefiltered (0.45 μm) Milli-Q water before use. Filters were checked under a microscope for contamination prior to use. The samples and equipment were covered where possible with aluminum foil or glass to minimize periods of exposure. All consumables were taken directly from their packaging and checked for contamination if possible. Personal protective equipment, 100% cotton lab coats and gloves were worn during the whole processing procedure. All procedures in the laboratory were conducted in a clean airflow cabinet (Labculture LA2-5A1-E)..
