Surface microplastics concentration in the Brazilian Amazon Continental Shelf from 2018-03-13 to 2018-10-23 (NCEI Accession 0276482)

Preview graphic

This dataset contains surface microplastics (i.e. plastics measuring less than 5mm, reported in unit of pieces/m^3) concentration in the Brazilian Amazon Continental Shelf from 2018-03-13 to 2018-10-23. Microplastics data was collected during two oceanographic cruises: one in March (rainy season) and the other in October (dry season) of 2018. The microplastics sampling effort involved using a 20L aluminum bucket to collect 60L of surface water and filtered through a 64-μm mesh plankton net. This dataset contains the results from all 57 sampling efforts, in a spreadsheet format.

Processing Steps	Parameter or Variable: MICROPLASTIC CONCENTRATION (measured); Units: pieces/m3; Observation Category: in situ; Sampling Instrument: Aluminum bucket; Sampling and Analyzing Method: Surface ocean microplastics samples were obtained during two oceanographic cruises: one in March (rainy season, at 25 points) and the other in October (dry season, at 32 points) of 2018, totaling 57 samples. The sampling points were distributed over the Brazilian Amazon Continental Shelf, from the states of Maranhão to Amapá. The large river basins such as the Amazon and Tocantins-Araguaia as well as São Marcos Bay provide enormous inputs of fresh water and sediment to the shelf. Half of the stations were located inside the Amazon River plume during the rainy season, with salinity levels below 34, while salinity was below 33 at only a single station during the dry season. Surface water samples were collected with the aid of a 20-L aluminum bucket. At each sampling point, 60 L of surface water was collected and filtered on board through a 64-μm mesh plankton net, which was washed between each sampling point. The retained material was immediately transferred to clean, labeled bottles with pre-filtered formaldehyde added in a 2% final concentration, and kept in a dark room until laboratory analysis. The filtered samples were examined under a stereoscopic microscope (Olympus, model CX41). All potential plastic particles were classified, photographed, counted, and measured.; Data Quality Method: The use of white cotton laboratory coats was standard, in addition to constant cleaning of materials and benches with reverse-osmosis water before and after use. Plastic materials in the laboratory were replaced by glass, aluminum, and paper whenever possible, to avoid contact with plastic fragments during manipulation of the samples. To monitor possible contamination sources such as airborne fibers during laboratory procedures, the samples were prepared and filtered in a glass still-air box coupled to a vacuum pump. Blank controls were performed for the filtration steps, as well as for the sample bottles and the reverse-osmosis water. The laboratory procedures and blank controls: i) glass bottle and reverse osmosis water, ii) still-air box (filtration steps), and iii) filtered formaldehyde included filtration of three replicates of 1 L of solution for each control treatment. Of the 57 filtered samples, 10 (five from each season) were randomly chosen and analyzed by 2D imaging FTIR, using a Cary 620–670 FTIR microscope equipped with an FPA (Focal Plane Array) 128 × 128 detector (Agilent Technologies) and a 15× Cassegrain objective. FPA detectors are widely accepted primary choices for the identification of microplastics, as they allow spatial resolution in the micron range, allowing direct analysis of microplastics on the filters without pre-treatments, even in the presence of mixed organic-inorganic matrices, such as deposits around the microplastics or composite materials. The analysis was carried out in reflectance mode, with an open aperture and a spectral resolution of 8 cm−1, acquiring 128 scans for each spectrum. Each analysis run delivers a “tile”, i.e., a map 700 × 700 μm2 (128 × 128 pixels), where each pixel has a size of 5.5 × 5.5 μm2 and provides an independent spectrum. The detection limit of the FPA detector is ca. 0.02 pg.μm−2. For each filter, ten tiles were acquired at different representative filter locations, analyzing micro-fragments and fibers. All the fragments/fibers were identified by comparison of their IR spectra with published standards for plastic and cellulose polymers..
