Oceans around the globe have become darker in the past two decades and, according to a new study, have frightened the researchers for their sea creatures.
Professor Thomas Davies from the University of Plymouth said in a study in The global change biology Journal There is growing concern about the sea ecosystem.
Satellite data from Nasas Ocean color web The data portal showed that 21% of the planet’s oceans were darkened between 2003 and 2022.
According to Davies, the majority of marine life lives in the Phhotic zones of the ocean, where there is enough light to stimulate photobiological processes.

In the 200 meter depth of Phhotic Zone, the global nutrients and carbon budgets receive the planetary fish markets.
This is the area in which light is enough Marine life This lives closer to the surface of the ocean.
These residents of the ocean rely on both The moonlight And sunlight for hunting, pairing, reproduction and other important milestones.

In the upper level of the ocean, microscopic organisms and different types of plankton live.
When the oceans begin to darken, creatures that rely on the light are approached in the surface and may create a cramped living space.
Using satellite data and a level derived from algorithm for the weakening of light in sea water, Davis was able to measure how deep every photic zone around the world was.
Among the darker oceans, 9% of their Phhotic zones were 50 meters flatter, and 3% of the Phhotic zones of the oceans were 100 meters flatter.

The reason for the darkening of the oceans, which is by far offshore, is less clear.
Global warming According to the study, it is assumed that changes in marine currents are involved in this phenomenon.
Despite general darkening, around 10% of the oceans or 37 million square kilometers have become lighter in the past 20 years, according to the study.

It also found the most firm Coastal areas seen an increase in light. However, the study showed that this does not lead to a net reduction of the Phhotic zone depth near the coastal lines.
Davies predicts that the effects of the darkness of the ocean for sea food networks, global fishing as well as carbon and nutrient budgets could be serious.
