coefficients are summarized in Table D3. In processing the measured time
series, the calibration formula was applied to each "instantaneous" sample of
sensor "counts" to convert OBS data to suspended sediment concentration in
grams per liter.
Data Recovery
Data recovered from all instrumentation deployed on the SIDSEP and
HESTT are summarized in Table D4. Table D4 shows the deployments and
recovery times for the deployments as well as the total amount of recorded and
processed data. Pressure data loss occurred as a result of instrument emergence
at low tide. Velocity data loss occurred as a result of sensor motion and
instrument emergence at low tide. HESTT sta OS 7 was not recovered.

Calibration Formula: y = Ax + Bx + C.
Where y is suspended sediment concentration in g/L, x is OBS sensor "counts", and A, B, and C are calibration
coefficients.
