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

-

Figure 9. Seasonally averaged diel pattern of depth-integrated computed suspended solids concentration (SSC) in the entire water column and in the upper and lower one-half (upper one-third and lower two-thirds at ADCP1) of the water column. Time of maximum and minimum near-surface and near-bottom current speed and maximum and minimum surface-to-bottom temperature difference are shown for reference. Computed SSC are derived from an average of 30-minute values between June 21 and September 12, 2005. Shading indicates ± 1 standard error around the estimate of mean SSC concentration.
