Figure 8 Floating-bar plots of elements in sediment for the years of 1984-88. Plot components are arithmetic mean concentration [long horizontal bar], one standard deviation [box], geometric mean [short horizontal bar], comparison interval [I shaped symbol], and maximum comparison interval value [squigley line] for the reference site [shaded box]. Sites are ranked in order of arithmetic mean concentration along the x-axis. See Tables 1 and 3 for abbreviations. Numbers for each site indicate sample size.
