Figure 10.2 Average percent cover and biomass values (+ 1 std. err.) of benthic green macroalgae in 
the Yaquina Estuary between June 1999 and May 2000. The values are averages for six sites 
within Zone 1. 
10.4 Percentile Approach 
CDFs for both dry and wet season were calculated for benthic green macroalgal biomass data 
from 1998-2004 within Zone 1 of Yaquina Estuary. In addition, CDFs were calculated for data from 
the Classification surveys conducted during the dry season in Zones 1 and 2 of six other Oregon 
estuaries (Table 10.1).
