Figure 3 : Seasonality of regional inputs of river plastic to oceans.

From: River plastic emissions to the world’s oceans

Figure 3

(a) River outflow locations are indicated by trimestral period when respective peak input occurs. Peak seasons for precipitation rates from GLDAS21 are mapped on the continental landmass, showing a clear correlation with our predicted inputs. (b) Relative seasonality of plastic inputs from rivers into the ocean by continents. Continental contributions are expressed in percentage of respective annual mass inputs.
