The Hawke’s Bay Regional Council says low dissolved oxygen levels from an algal bloom may be the cause behind the deaths of sea animals washing up on shore in Napier. Science manager Anna ...

Florida Fish and Wildlife Conservation Commission scientists concluded that low dissolved oxygen levels were spurred by high temperatures and heavy rainfall which are common during the summer months.

The larger number of blood vessels in fish gives a much larger surface for oxygen to pass across. That helps them pull the dissolved oxygen from the water, and release carbon dioxide back into the ...

"The answer is 99.9 per cent sure: we believe the dissolved oxygen was too low," Clement ... Zoocheck Canada, an animal rights group based in Calgary, is calling for an independent investigation ...

The study aimed to investigate the effects of temperature and dissolved oxygen on juvenile largemouth bass during transportation. The experiment involved four temperature groups: 20, 15, 10, and 5 °C.

The waters of Hood Canal are notoriously low in dissolved oxygen — regularly falling to levels within the “stress zone” for marine life. But this year was particularly bad. “This is really ...

Kristian Foden-Vencil / OPB Scientists say warming ocean temperatures mean Oregon's coastal waters now have a low-oxygen season, or hypoxia season, just as the state's forests have a fire season.

Global warming is causing lakes to lose their oxygen 1. Oxygen is crucial for aquatic life to thrive. But levels of dissolved oxygen have declined in many watery environments, including rivers and ...
