In situ light and dark planktonic and benthal respirometers were
used to measure the oxygen requirements of Yaquina estuary water
and benthal deposits. Respirometer devices were constructed so that
actual conditions of mixing could be simulated and benthal deposit
disturbance would be minimized.
A mathematical model of a benthal respirometer was developed
and was used to make corrections for respirometer leakage and to
conduct oxygen transfer parameter sensitivity studies. The effect of
mixing on benthal oxygen uptake was studied by varying the simulated
mixing velocities. Studies were made to determine the effects of
scour of bottom material on the salinity of the respirometer water and
on the benthal oxygen uptake rates. Plots of various parameters such
as benthal oxygen uptake versus dissolved oxygen concentration and
respirometer leakage versus time were made to attempt to evaluate
relationships that may exist. / Graduation date: 1970
