Bay SM, Weisberg SB. 2011. A framework for interpreting sediment quality triad data. Integr Environ Assess Manag 8:589–596.

Table 4 contained incorrect values for some of the chemistry and benthos lines of evidence thresholds. In addition, there were inconsistencies in the use of logical symbols (e.g., <or>). The symbols and thresholds have been corrected in the following table.

Table 4. Ranges of values used to define each LOE indicator category. Separate benthic index ranges are used for southern California and San Francisco Bay habitats.
