Figure 4. (A) Relative MP particle size distribution from all analyzed stations (np = 4,090). Dark blue bars represent particles by length. Light orange bars represent the geometric mean of particle size based on length and width. Particle lengths and widths were measured using PMF; (B) Polymer size abundance across all sea ice samples shown as ESD on a logarithmic scale. MP: Microplastic; PMF: Purency Microplastic Finder; ESD: equivalent spherical diameter.
