Abstract
A device for stratified in-situ monitoring of the water quality and dissolved oxygen of sediments in a tidal river network region includes a floating platform. Three take-up and pay-off assemblies are fixedly connected to the edge of a top surface of the floating platform. The device can provide high-density data of stratified dissolved oxygen, all monitoring units perform sampling and monitoring directly at the positions where they are located, samples do not need to be transferred, sediments will not be disturbed, and monitoring is performed in the field environment, such that researchers can obtain the long-term diurnal change of stratified dissolved oxygen and the continuous change process of dissolved oxygen in one and even multiple hydrologic years, and basic data is provided for study of the dissolved oxygen change mechanism and accurate control of the water environment in tidal river network regions.
