Microplastic concentration and composition in surface waters of the Weddell Sea, Antarctica

DOI

The dataset provides information about the microplastic contamination in surface waters of the Weddell Sea, Antarctica. Samples (n = 34) were collected during two expeditions on RV Polarstern, PS111 (2018) and PS117 (2018/2019), to the Antarctic Weddell Sea, taking place during austral summer. Samples were collected with a surface trawl (manta trawl; 5gyres Institute, Los Angeles, California; 60 x18 cm² rectangular aperture) equipped with a 300 µm mesh and a mechanical flowmeter. On average 234.6 (±83.7 SD) m³ of seawater were filtered per sample (total filtered volume: 7974 m³). Putative microplastic particles were sorted visually under a dissecting microscope (magnification 6.7-45x) and analyzed by means of by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy.
