Use of Acoustic Backscatter and Vertical Velocity to Estimate Concentration and Dynamics of Suspended Solids in Upper Klamath Lake, South-Central Oregon: Implications for Aphanizomenon flos-aquae

Table 4. Correlation coefficients between the depth-integrated computed suspended solids concentrations (SSC) at ADCP sites and depth-integrated horizontal currents at the same site, or air temperature as measured at site WMR-MET, Upper Klamath Lake, south-central Oregon. 


[Locations of sites are shown in figure 1. Time series were filtered to pass periods between 1.2 and 15 days. Correlation coefficients greater than 0.25 are significant and indicated by boldface type (p<0.05). ADCP, acoustic Doppler current profiler]
