Research reveals the potential effects of ocean darkness on marine ecosystems
Oceans around the world According to a new study, researchers have been dark over the past 20 years, and researchers fear Marine residents.
Professor Thomas Davis of the University of Plymouth Global Change Biology Journal Marine ecosystems are growing concern.
Satellite data from NASA’s Ocean Color Web The data portal showed that 21% of the planet’s oceans were dark between 2003 and 2022.
According to Davis, most marine life lives in the ocean light zone. There, enough light penetrates to stimulate photobiological processes.

The 200m deep light zone is where the world’s nutrients and carbon budgets maintain the planet’s fish market.
This is the area where light reaches Marine life It’s close to the surface of the ocean.
These marine inhabitants rely on both moonlight Sunlight for hunting, mating, breeding and other important milestones.

The upper part of the ocean is where microscopic organisms and different types of plankton live.
As the ocean begins to darken, light-dependent creatures can begin to approach the surface, creating cramped living spaces.
Using satellite data and algorithm-derived measures of light attenuation in seawater, Davis was able to measure how deep each of the light zones are all over the world.
In the dark seas, 9% of its light zone was 50 meters shallow, and 3% of the ocean’s light zone was 100 meters shallow.

The reason behind the darkening of offshore oceans is less clear.
global warming Research shows that changes in ocean currents are thought to be involved in this phenomenon.
Despite being darker overall, about 10% of the ocean, or 37 million square kilometers, have been lighter over the past 20 years, the study found.

Also, most have discovered it Coastal area An increase in light was seen. However, this study found that this did not lead to a net reduction in the light zone depth near the coastline.
Davis predicts that the meaning of marine darkening could be serious for marine food networks, global fisheries, carbon and nutrition budgets.
