Figure 35. Relationship between sediment surface TOC and silt/clay content.
(A = reference line defined by equation, %TOC = 0.20 × %silt/clay;
B = regression of Old Place
Creek data -- both spring and fall -- and Mill Creek spring data; OP =
Old Place Creek; and MC = Mill Creek. Old Place Creek - Station C in May
(circled) lies outside
of the zone delineated by all other Old Place Creek station-season combinations.
Con Ed Tower data are not plotted due to lack of grain size data. Grain
size data
are from Chapter II, “Trace Metal Contaminants in Sediments and Ribbed-Mussels.”)
