DOxy: A Dissolved Oxygen Monitoring System [PDF]

open access: yesSensors
Dissolved Oxygen (DO) in water enables marine life. Measuring the prevalence of DO in a body of water is an important part of sustainability efforts because low oxygen levels are a primary indicator of contamination and distress in bodies of water ...

A Dissolved Oxygen Threshold for Shifts in Bacterial Community Structure in a Seasonally Hypoxic Estuary. [PDF]

open access: yesPLoS ONE, 2015
Pelagic ecosystems can become depleted of dissolved oxygen as a result of both natural processes and anthropogenic effects. As dissolved oxygen concentration decreases, energy shifts from macrofauna to microorganisms, which persist in these hypoxic zones.

Dissolved Oxygen for Fish Production

open access: yesEDIS, 2020
This document is about dissolved oxygen (DO). DO refers to oxygen gas that is dissolved in water. Fish "breathe" oxygen just as land animals do. However, fish are able to absorb oxygen directly from the water into their bloodstream using gills, whereas ...

A Statistical Technique for Modelling Dissolved Oxygen in Salt Lakes

open access: yesCogent Engineering, 2021
An integrated linear regression technique was developed and validated to model dissolved oxygen in salt lakes by using R software and based on data from Sawa Lake, Iraq. The technique helps understand and evaluate salty aquatic ecosystems in the presence

Advanced Computational Fluid Dynamics Study of the Dissolved Oxygen Concentration within a Thin-Layer Cascade Reactor for Microalgae Cultivation

open access: yesEnergies, 2021
High concentration of dissolved oxygen within microalgae cultures reduces the performance of corresponding microalgae cultivation system (MCS). The main aim of this study is to provide a reliable computational fluid dynamics (CFD)-based methodology ...

The Effect of Diel Variation of Dissolved Oxygen Content in a Pond on the Glucose Metabolism and Plasma Glucose Level of Siniperca chuatsi

open access: yesProgress in Fishery Sciences, 2023
Diel variation of dissolved oxygen content in aquaculture is common. Generally, the dissolved oxygen content in the pond is the highest in the afternoon and the lowest in the early morning.

Cerium anomaly as a tracer for paleo-oceanic redox conditions: A thermodynamics-based Ce oxidation modeling approach

open access: yesFrontiers in Earth Science, 2022
Reconstructing redox conditions in the paleo-ocean is essential to understand the Earth’s biogeochemical evolution. Cerium (Ce) anomaly in marine sediments has been used to distinguish oxic versus anoxic depositional environments in the Paleo-ocean ...

The dependence of the consumption of dissolved oxygen on lake morphology in ice covered lakes

open access: yesHydrology Research, 2020
The consumption of oxygen in ice-covered lakes is analyzed and related to biological oxygen demand and sediment oxygen demand. An approach for computing dissolved oxygen concentration is suggested assuming horizontally mixed waters and negligable ...
