Global warming: lakes lose too much oxygen

Changes threaten biodiversity and drinking water quality

Oxygen levels in freshwater lakes are declining rapidly – faster than in the oceans. Over the past forty years, for example, oxygen levels in the deep waters of temperate lakes have dropped by nearly 19 percent. This is shown by a study with IGB published today in the journal Nature. This trend is mainly due to climate change and threatens freshwater biodiversity and drinking water quality.
The international research team, led by the U.S. Rensselaer Polytechnic Institute, analyzed a total of more than 45,000 oxygen and temperature profiles collected from nearly 400 lakes around the globe since 1941. Most of the long-term data came from the temperate zone, which ranges from 23 to 66 degrees north and south latitude. The analyses show that since 1980, oxygen levels in the lakes studied have declined by 5.5 percent ....

Climate change: Worldwide emergence of dead zones in lakes

Date Time
Climate change: Worldwide emergence of dead zones in lakes
As climate change progresses, lakes also warm up, the oxygen concentration in the water decreases and dead zones in deep zones develop. Ruben Sommaruga from the Institute of Ecologyand an international team of researchers were the first to identify this dramatic widespread development in a study of 393 lakes around the world. The results were published in the journal Nature.
The temperature in lakes is also subject to the continuous warming of the climate. As water temperature increases, gas diffusion at the surface of lakes decreases and thus, the oxygen concentration in the lake decreases as well. Ruben Sommaruga and more than 40 scientists from all over the world studied the oxygen concentration in relation to temperature in 393 lakes over a period of more than 70 years. A total of 45,000 combined profiles of temperature and oxygen were analyzed. This close collaboration was made possible by the Gl ....
