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, ...

In a new review, scientists warn that this rapidly escalating, human-driven crisis threatens to upend the biosphere. The paper, published June 30 in the journal Limnology and Oceanography, argues that ...

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 ...

Image Courtesy of Maryland Department of Natural Resources CHESAPEAKE BAY – Recent data from July shows better-than-average dissolved oxygen conditions in the Chesapeake Bay. Figures collected by the ...

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

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, ...

Dissolved oxygen analyses are performed with an SIO/ODF-designed automated oxygen titrator using photometric end-point detection based on the absorption of 365nm wavelength ultra-violet light. 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 ...

What is dissolved oxygen (DO)? Why is this parameter so relevant, e.g., for water analysis, and which technologies are used to determine it? In a free White Paper, Dr. Sabrina Gschwind, product ...
