Jul 19, 2024 · Supplies of dissolved oxygen in bodies of water across the globe are dwindling rapidly, and scientists say it's one of the greatest risks to Earth's life support system. Just as atmospheric oxygen is vital for animals like ourselves, dissolved oxygen (DO) in water is essential for healthy aquatic ecosystems, whether freshwater or marine.
Jul 15, 2024 · Since 1960, oceans have experienced oxygen losses of around 2%. And although that number is smaller, it represents a more geographically and volumetrically extensive mass of water, considering that the ocean covers more than 70% of Earth’s surface. Marine ecosystems have also experienced substantial variability in oxygen depletion.
Jul 15, 2024 · Oxygen is a fundamental requirement of life, and the loss of oxygen in water, referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, researchers describe how ongoing ...
Jun 10, 2021 · Fish could be left gasping for air as oxygen levels plunge in the world's freshwater lakes due to climate change, a new study suggests. "The Earth is getting warmer. And as it does, the lakes are ...
Sep 14, 2023 · When water warms, it holds less oxygen, and this can harm aquatic life and degrade water quality. A new study finds that climate change is driving oxygen loss in hundreds of US and European rivers.
Jul 14, 2023 · Oxygen becomes less soluble at higher temperatures, which means warm water holds less oxygen than cold water. Eutrophication due to excess inputs of nutrients like nitrogen and phosphorus from ...

Jun 8, 2023 · The volume of anoxic water grew by 52% over the same time period. The proportion of lake water columns below the 5 mg threshold grew between 0.9% and 1.7% on average each decade, depending on the threshold examined. Such oxygen depletion threatens the habitability of deep-water environments.
