Der #Sauerstoffgehalt in Seen weltweit sinkt dramatisch. Laut einer Studie in Science Advances um bis zu 18,6 % in tieferen #Wasserschichten seit 1980.
Hauptursachen sind steigende #Temperaturen, zunehmende #Hitzewellen und #Algenblüten durch #Düngemittel-Einträge.
Über 80 % der untersuchten 15.000 Seen zeigen bereits #Sauerstoffmangel. Die Folge sind zunehmendes #Tiersterben und instabile #Ökosysteme.

Under anthropogenic stress, we talk a lot about #ocean #warming and ocean #acidification... but we should also be talking more about ocean #deoxygenation, as it is an ongoing problem. To understand just how bad it can get ( #extinction event bad ), we must turn, as usual, to the geological record.

#Oxygen is a fundamental requirement of life on planet Earth. The loss of oxygen in water, also referred to as #aquatic #deoxygenation, is a threat to life at all levels. The international team of researchers describes how ongoing deoxygenation presents a major threat to the livelihoods of large parts of society and for the stability of life on our planet.

" It was discovered that a staggering 87% of the #rivers studied were experiencing persistent #warming, while 70% were suffering from #deoxygenation. While this phenomenon is more commonly associated with larger bodies of water like oceans and lakes, its presence in flowing rivers is a growing concern that has largely gone unnoticed until now."

#Deoxygenation is commonly observed in #oceans and #lakes but less expected in #rivers. Assessments of almost 800 rivers revealed persistent warming in 87% and deoxygenation in 70% of the rivers. Mean deoxygenation rates per decade were higher than those in oceans. Projected future rates are between 1.6 and 2.5 times higher than historical rates, indicating significant ramifications for #waterquality and #aquatic #ecosystems.

Deoxygenization is happening. Dead zones are increasing in number and size.
"Oxygen levels in the world’s oceans have already dropped more than 2 percent between 1960 and 2010, and they are expected to decline up to 7 percent below the 1960 level over the next century."

Thousands of dead fish have washed up on Quintana Beach, Texas, due to a phenomenon called ocean deoxygenation. Ocean deoxygenation is the water's loss of oxygen caused by climate change, pollution, and overfishing. Ocean deoxygenation threatens marine life, biodiversity, and food security and worsens global warming.

Ocean oxygen: The role of the Ocean in the oxygen we breathe and the threat of deoxygenation | New report of the European Marine Board
#Deoxygenation is increasing in the coastal and open Ocean, primarily due to human-induced #globalwarming and nutrient run-off from land, and projections show that the Ocean will continue losing oxygen as global warming continues.

#oceanograpy in the news for all the wrong reasons - plus must remember to sit on my hands during interviews… it’s good that some countries will invest in collecting this vital data - just frustrating that it’s not NZ #climate #deoxygenation https://www.newshub.co.nz/home/world/2023/05/antarctic-ocean-currents-have-slowed-since-1990s-sparking-fears-of-collapse.html

@SWAIS2C great to see this study out - one of the authors is UoAkl and #ASP colleague Melissa Bowen who works tirelessly to make this mahi happen. And the key message in the paper is about #deoxygenation which is scary.

Record temperature combined with an anticipated El Niño could devastate marine life and increase the chances of extreme weather.
"With #ocean warming and #deoxygenation, the available habitats for many #species are decreasing."

The overall decline of #oxygen content across the world’s #oceans and #coastal waters—a process known as ocean #deoxygenation—has been well documented, but #hypoxia on #coral #reefs has been relatively underexplored. Oxygen loss in the ocean is predicted to threaten #marine #ecosystems globally

It would be really very cool to make #BiodiversityStripes for #marine #biodiversity. Like these ones for #freshwater #species from https://findingnature.org.uk
The #ocean #ecosystems are getting weaker due to #ClimateChange, #OceanAcidification, #Deoxygenation, #Overfishing.
There are robust #datasets for different marine species around, aren't there?

"Rapid rates of sea level rise, deglaciation, and increased marine deoxygenation are hallmarks of modern climate change. O2 contents have declined by at least 2% over the past 50 years, and models predict continued declines by as much as 7% over the next century"
