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.

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 ...

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 ...

Lake Texoma ranked as one of the least clean major lakes in the United States, with several concerning measurements.

A peer-reviewed paper published in Nature Ecology and Evolution argues that the steady loss of dissolved oxygen across the world’s oceans, lakes, and reservoirs qualifies as a tenth planetary boundary ...

After all the work you’ve done with lighting, extractor fans, nutrients, grow medium, watering and everything else you need to consider when growing good cannabis indoors, an invisible component of ...

The absorption of light by organic molecules with chromophores contribute to the formation of brown carbon in the atmosphere, which can partially counteract the expected cooling effect of aerosols on ...

The study analyzed water quality data from 100 of the country’s largest lakes, focusing on factors like oxygen levels, chemicals and overall water quality. Lake Texoma was found to be poorly ...

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 ...

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 ...
