THE fact that there is in every ocean a zone of minimum oxygen is of interest not only to the physicist and chemist but also to the biologist, and it is very desirable that we should know what ...

Douglas Wallace was on a research ship in the middle of Canada’s Gulf of St. Lawrence when he heard the news: Canadian Prime Minister Justin Trudeau had met with Olaf Scholz, the German ...

The Global Ocean Oxygen Network — a scientific group set up as part of the United Nation’s Decade of Ocean Science for Sustainable Development, 2021-2030 — reports that since the 1960s, the ...

Since the 1960s, the oxygen level in the world’s oceans has dropped by about 2 percent.While that may not sound like a lot, the continuous decline in oxygen content of oceanic and coastal waters ...

Efficiency might be key to survival where the samples originated, in an oxygen minimum zone about 50 to 150 meters below the surface, where oxygen and light are both in short supply. "It's very ...

New research challenges a long-held assumption about oxygen in the deep sea, with scientists finding oxygen produced without photosynthesis in the Clarion-Clipperton Zone.

Researchers created this visualization of the Pacific's oxygen minimum zone from observations and the 2018 World Ocean Atlas. The colors approximately indicate the core (purple) that has almost no ...

In the Gulf of St. Lawrence—where the size of the dead zone grew nearly sevenfold from 2003 to encompass roughly 9,000 square kilometers in 2021—dropping oxygen levels are already affecting ...
