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 ...

The Neritic Zone is one the layer or zone. The Neritic Zone is the shallow region of the ocean above the drop-off of the continental shelf, approximately 200 meters in depth.

While these factors will clearly influence light attenuation in neritic coastal waters, darkening in the open oceans may be driven by warming of the surface oceans and climate-driven changes in ...

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.

Naturally caused dead zones in open water, like the one off Oregon, are rare and less well understood. Others have been found off the coasts of Peru and South Africa.

With the twilight zone, we have an opportunity to transform how humanity relates to little known — yet potentially indispensable — ecosystems and resources.

Now, a group of German and Canadian researchers have discovered dead zones in the open waters of the Atlantic Ocean, which they say is a first.

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.

The expedition is trying to figure out how the structure and function of the biological communities above the twilight zone affect how much carbon is being transported to the deep ocean.
