Fig. 5: Seasonal and longitudinal variability in MP distributions (2014–2016) using Hovmöller diagrams.
From: Modeling river and urban related microplastic pollution off the southern United States
Each box displays the percentage of MPs within the corresponding longitude range, relative to the total number of settled or non-settled MPs released in that month. The left panel represents settled MPs, and the right panel shows non-settled MPs. The three black dotted lines from top to bottom mark the approximate longitudes of the Greater Houston, the Mississippi Delta, and the beginning of the western Florida shoreline, respectively.
