Preview graphic

This study was carried out to estimate the microplastics (i.e. plastics measuring less than 5mm, reported in unit of pieces/m^3) concentration in the mid-North Pacific Ocean. Microplastics data was collected from 2019-09-19 to 2019-10-30 aboard RV XIANG YANG HONG 03. Microplastics samples were collected using manta net. This dataset contains the results from all 15 sampling stations, in a spreadsheet format.

Processing Steps	Parameter or Variable: MICROPLASTIC CONCENTRATION (measured); Units: pieces/m3; Observation Category: in situ; Sampling Instrument: Manta net; Sampling and Analyzing Method: The 42-day field cruise was performed on the oceanographic research and survey vessel XIANG YANG HONG 03 owned by the Third Institute of Oceanography, Ministry of Natural Resources of China. A manta trawl net featuring a shaped aperture with 60 cm × 13.5 cm (width × height), a net length of 1.67 m (mouth-to-cod end), and a net mesh size of 330 µm, was used to collect surface microplastic samples in the mid-North Pacific Ocean. It is an advantage to use manta trawling to cover such a large sampling area to obtain representative reduced-volume microplastic samples. The manta trawl deployed off the side of the vessel was towed horizontally at the surface at a speed of 2–3 knots for approximately 30 min at each site. The start and endpoint of trawling (longitude and latitude) were recorded using a GPS map 78S (Garmin, USA) for each sampling. A mechanical and electronic digital flowmeter (Model 2030R, General Oceanics, United States) was mounted at the center of the manta trawl mouth for estimating the total volume of water filtered through the mesh during each tow. Before each sampling, 10 L of Milli-Q water was progressively poured into the manta trawl net at one time as a blank control. Following each tow, all the contents on the net were collected in the cod end upon flushing down from outside of the net using onboard seawater, Afterwards, the entire samples in the cod end were washed into a 1-L pre-cleaned glass jar with Milli-Q water and preserved in an ice-cooler before laboratory analysis. The microplastic samples were processed using the NOAA protocol. Water samples were first filtered through stacked 5-mm and 0.3-mm standard sieves. The unwanted large agglomerates captured by the 5-mm mesh screen (>5 mm) were removed. The remaining in the 0.3-mm mesh screen was thoroughly washed into a 1 L beaker with a sufficient volume of Milli-Q water and covered in aluminum foil to prevent airborne contamination. The mixture was dried in the oven (Model 56, BINDER drying chamber, United States) at 75 ℃ for at least 24 h. Subsequently, the samples were digested using 30–50 mL of 30% hydrogen peroxide and 30–50 mL of 0.5 M FeSO4 at room temperature. The wet digestion procedure was performed under the hood. The mixtures were left overnight to eliminate any organic residues. Afterward, the reacted sample was completely transferred to a 1000-mL separatory funnel, then 300 g of L-1 NaCl solution was poured in for density separation and the mixture was allowed to settle overnight. The following day, the settled material was drained and the supernatant was vacuum filtered through a GF/A Whatman filter (d = 47 mm, pore size = 0.7 µm, CAT No. 1820–047, GE Healthcare Life Sciences, United States). The particles in the filtrate paper were carefully picked up using tweezers to ensure complete transfer of samples to a glass Petri dish for air drying at room temperature under the hood. All the suspected microplastic particles were visually screened and photographed using a stereo light microscope (Leica M205FA, Germany) coupled with a Leica DFC425 charge-coupled device (CCD) camera. The number of microplastics per cubic meter of water volume (items/m3) was used as a measure of microplastic abundance.; Data Quality Method: The polymer composition was identified by Senterra II Compact Raman Microscope (Bruker Optics Inc., United States) coupled with an optical microscope with grafting of 1200 lines/mm using 20× and 50× objectives (Infinity, United States). Lasers (wavelength = 785 nm) of 1–60 mW were used to excite the MPs particles with signal acquisition times of 10–60 s per measurement. The Raman spectral resolution and ranges were set as 3–5 cm-1 and 400–4000 cm-1, respectively. The obtained spectra were matched with the in-built reference spectra to identify microplastic polymer composition using OPUS 7.5 software (OPUS software Inc., United States)..
