Across oceans, lakes, and rivers, one of the most basic ingredients for life is quietly disappearing. Dissolved oxygen, the gas that fish, crabs, and countless microscopic organisms need to breathe, ...

Chinese scientists have recently developed a novel method for measuring dissolved oxygen (DO) levels in the ocean and a new dataset for monitoring dissolved oxygen concentration (DOC) of global oceans ...

Dissolved oxygen meters are used to quantify the amount of dissolved oxygen (DO) in surface waters or at different stages of wastewater treatment. There are two dissolved oxygen meters in the ...

The amount of dissolved oxygen in a river is a matter of life or death for the plants and animals living within it, but this oxygen concentration varies drastically from one river to another, ...

housands of dead fish were found floating in Turkey Creek and washing ashore in Hanahan, prompting an investigation by the ...

Reactive oxygen species (ROS) are critical drivers of aquatic biogeochemical processes, with dissolved organic matter (DOM) serving as a primary photosensitive source of ROS in natural waters. Despite ...

Modern-day Mars may be more hospitable to oxygen-breathing life than previously thought. A new study suggests that salty water at or near the surface of the red planet could contain enough dissolved ...

Fish and other aquatic organisms survive in water because of DO. The amount of DO in water is affected by the water temperature, salt concentration, and atmospheric pressure, among other factors.
