  This study clarified the sampling characteristics (e.g., mesh selectivity) and fluid characteristics (e.g. filtration efficiency, fluid resistance, and mesh mouth dynamics) of a neuston net with 0.350 mm mesh size, which is internationally standard for collecting microplastics (MPs) drifting on the ocean surface.
  In particular, mesh selectivity (retention probability by MPs size) was estimated, which suggested that fine MPs (especially fibrous) were missing from the mesh. And a correction method for MPs size composition was also presented. Visualization of the flow around a neuston net towed with the net mouth half out to sea surface was conducted to estimate the filtration efficiency by towing speed. The water flowmeter properly attached to the net mouth was demonstrated to effective to estimate a water volume filtered by the net. The hydrodynamic characteristics of a fine mesh plane netting were clarified, providing basic data for hydrodynamic studies on fine mesh nets.
