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 ...

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 ...

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.

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 ...

Dark oxygen is being created on the ocean floor, scientists have discovered – and it could change our understanding of how humans and animals evolved. It was traditionally thought that only ...

The Titanic tourist submersible that vanished on a trip to the 112-year-old shipwreck at the bottom of the Atlantic Ocean has run out of oxygen, according to officials’ estimate.

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 ...

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 ...

Since the industrial revolution, this zone has risen for all parts of the ocean, varying from almost no rise in the western Indian Ocean to more than 300 metres in the northwest Atlantic. If the ...

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 ...
