(a)–(e) Circle charts from each sampling event with the area of the circle representing the samples' corresponding EC concentration
Figure 1. (a)–(e) Circle charts from each sampling event with the area of the circle representing the samples' corresponding EC concentration. The area of the circles are relative as Pallas concentrations are much lower than Tyresta (see table 1). Ordinate and coordinate scales are in metres. C...

Figure 1. (a)–(e) Circle charts from each sampling event with the area of the circle representing the samples' corresponding EC concentration.
