Almost all life in the ocean depends on the upper waters where sunlight filters in, known as the photic zone – but new research suggests this narrow window of valuable marine light is shrinking ...

"If the photic zone is reducing by around 50 m in large swathes of the ocean, animals that need light will be forced closer to the surface where they will have to compete for food and the other ...

Using data from 2003 to 2022, the team found nearly 10% of the ocean’s photic zone has been squeezed by 50 m (164 ft). More dramatically, photic zones in some oceans have shrunk by 100 m (328 ft).

If the photic zone is reducing by around 50m in large swathes of the ocean, animals that need light will be forced closer to the surface where they will have to compete for food and the other ...

The photic zone, which is 200 meters ... Using satellite data and an algorithm-derived measure of the attenuation of light in seawater, Davis was able to measure how deep each photic zone was ...

But the photic zone is shrinking, rendering that figure inaccurate in some parts of the ocean. A new study reveals that 21% of the ocean has gotten darker over the last two decades, making the ...

The photic zone extends roughly 200 meters below the ocean's surface, forming the base for countless marine ecosystems. But a recent study published in Global Change Biology shows alarming changes.

Researchers observed darkening in the photic zone of the oceans, where light filters through water in a sufficient enough way to sustain species that rely on sunlight and moonlight.

“If the photic zone is reducing by around 50 meters [55 yards} in large swathes of the ocean, animals that need light will be forced closer to the surface where they will have to compete for ...
