The originally published Figures 11-18 were based on an erroneous understanding of presentation of data. In short, 
the originally graphed estimated maximum biomass was actually the sum of the estimated minimum biomass and the 
actual estimated maximum biomass. The revisions corrected that misinterpretation. In addition, there were minor corrections to the text describing the figures. None of the revisions affected the overall data interpretations 
and also did not affect the Abstract or Summary and Conclusions sections.
