Enhanced mobility of microplastics on natural beds: exposure, abundance and bed mobility

Sample dataset for two condition for flat-bed experiments on the onset of motion of compact-shaped microplastics. It includes data for homogeneous bed tests and clastic (mixed) bed tests (of microplastics on sand bed). The research was carried out in the Hydrodynamic Models Laboratory at the Institute of Geophysics, Polish Academy of Sciences. UBERTONE is acknowledged for the UVP device used in the homogeneous bed tests, UB Lab P. University of Bologna provided the UVP for the clastic bed tests, a DOP2000 by Signal Processing. Homogeneous bed tests: UVP data and videos of bed movements. Sand bed tests: UVP data and video of bed movements, for one concentration (1% MPs cover of the bed) of microplastics on the bed surface.
