The Neritic Zone is the shallow region of the ocean above the drop-off of the continental shelf, approximately 200 meters in depth. It is also known as the coastal ocean, the coastal waters, or ...

Oxygen-starved ocean “dead zones,” where fish and animals cannot survive, have been expanding in the open ocean and coastal waters for several decades as a result of human agricultural and industrial ...

This darkening affected 21 percent of the global ocean between 2003 and 2022. This meant photic zones (the uppermost layer of a body of water where sunlight penetrates, allowing for photosynthesis ...

More than one-fifth of the global ocean—an area spanning more than 75 million sq km—has been the subject of ocean darkening over the past two decades, according to new research.

As invisible pollutants infiltrate our water, much of that water ends up flowing straight into our coastal zones. ... pollutants are diluted to safe levels by the time they reach the open ocean.

The Dead Zone dissipated that fall, and based on 40 years of ocean monitoring and local fishing lore, many thought they would never see it again. This summer, the Dead Zone came back.

Well below the sunlit surface, the twilight zone extends throughout the ocean in an immense, globe-spanning layer from 200 to 1,000 meters (660 to 3,300 feet) deep. Its life forms are fascinating ...

A 2014 Smithsonian report published in Global Change Biology found that 94 percent of the ocean's dead zones are in areas expected to warm up by at least 2 degrees Celsius by the end of the century.

They found these so-called dead zones in 100-mile long eddies, giant whirlpool-like structures that form in the open ocean and that can spin for months at a time.
