Whose work first described the ocean’s oxygen minimum zone?
Quick Answer
Oceanographers in the 20th century, especially studies by Harald Sverdrup and later researchers, identified midwater regions where oxygen levels drop sharply. These oxygen minimum zones are common in the tropical and subtropical oceans.
The Full Story
The oxygen minimum zone was recognized through 20th-century oceanographic surveys that measured how oxygen varies with depth. Harald Sverdrup and later scientists helped establish that midwater oxygen can become extremely low in broad regions of the ocean, especially beneath productive surface waters. These zones matter because they limit where many animals can live and migrate. They also influence nutrient cycling and the distribution of marine life.
