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 2. Correlations of computed suspended solids concentrations (SSC) at ADCP sites with chlorophyll a and dissolved oxygen at water quality sites, Upper Klamath Lake, south-central Oregon.


[Locations of sites are shown in figure 1. All correlations of SSC with chlorophyll a are at least weakly significant (p<0.16) and all correlations of SSC with dissolved oxygen are significant (p<0.02). ADCP, acoustic Doppler current profiler; N, number; ≥, equal to or greater than]
