- n. Plural form of hypoxia.
Sorry, no etymologies found.
The algae use up all the oxygen in the water, creating hypoxias, or huge dead zones in our oceans where no marine life can exist.
All told, 146 major hypoxias dot the world's oceans, and all are growing.
One of the world's largest hypoxias is in the Gulf of Mexico, near the mouth of the Mississippi River.
