Oscillating grid mesocosm for studying oxygen dynamics under controlled unsteady turbulence

摘要

In shallow environments, common unsteady flows, such as tides, waves or wind-driven currents modulate the diffusive boundary layer thickness that controls the exchange of electron acceptors for mineralization and oxidation processes in surficial sediment. This study demonstrated the ability of an oscillating grid mesocosm to (1) produce homogenous turbulence at the sediment-water interface of multiple sediment cores (between-core variability
