Figure 5 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.
