Extended Data Table 1 Key methodological steps in studying subsurface microplastics

From: The distribution of subsurface microplastics in the ocean

  1. This table outlines the methods used at various stages of subsurface microplastic measurement, including sampling equipment, filter/mesh types, and chemical identification. The advantages and limitations of each step are also provided. aThe mesh size of plankton pump is fixed. bMultiple Opening and Closing net with an Environmental Sensing System. cMultiple Plankton Sampler. dScreen filter utilizes a mesh screen to physically trap particles larger than the screen openings; Depth filter relies on a porous matrix of depth media to capture particles throughout the depth of the filter medium. eμ-FTIR/Raman means microscope-supported spectrometric (Fourier-transform infrared spectroscopy/Raman) systems. fMOCNESS and MultiNet can sample at multiple depths, its maximum sampling depth is typically limited compared to in situ pumps. gBulk water sampler (e.g., Niskin bottle CTD Rosette) can allow to collect water samples at precise depths throughout the water column.
