What is ocean deoxygenation?
ClimateOcean chemistry
Quick Answer
Ocean deoxygenation is the long-term decline of dissolved oxygen in seawater. It can create low-oxygen zones that stress or kill marine life.
The Full Story
Warming waters hold less oxygen, and changes in circulation can reduce how much oxygen reaches deeper layers. Nutrient pollution can also fuel algal growth that consumes oxygen as it decomposes. In some regions this process has enlarged or intensified oxygen minimum zones and coastal dead zones. Deoxygenation threatens fish, shellfish, and ecosystems that need well-oxygenated water to survive.
