Fig. 2: Comparison between the modeled and observed total surface ocean plastic mass concentrations.
From: Plastic waste discharge to the global ocean constrained by seawater observations

a, d High emission scenario. b, e Middle emission scenario. c, f Low emission scenario. In panels a–c, the background colors are the modeled annual mean for the year 2018, while the circles are observations. In panels d–f, the dashed lines are 100:1, 10:1, 1:1, 1:10, and 1:100. All the concentrations and the calculation of R2 and RMSE are in a base 10 logarithmic scale with a unit of g km−2. Sources of observation data are listed in Supplementary Table 8.
