A scientist at the National Oceanic and Atmospheric Administration has warned that ocean currents are becoming increasingly polluted by blue light from LED light bulbs.
Scientists at NOAA’s National Marine Fisheries Service have found that blue light is affecting fish in large numbers, and that this affects many marine species, including killer whales.
The fish kill is happening with alarming frequency and the effects are widespread, Dr. David Pecoraro, a scientist at NOAA Fisheries, told a meeting of the American Fisheries Association on Wednesday.
The effects are already being felt.
NOAA Fisheries researchers have found blue light pollution in some of the Great Lakes and other coastal areas in recent years, and have identified several species that have suffered from the damage.
Dr. Pecorelli said blue light levels were significantly higher in some parts of the world than others.
The effect is so severe that some fish species in the Great Gulf of Mexico, where the pollution is particularly bad, are actually losing up to 20 percent of their size, according to Dr. Pacoraro.
In many cases, the blue light exposure was so extreme that fish could not even swim to the surface.
This has a devastating effect on fish, Dr Pecori said, adding that this has become a “serious threat” to marine life.
Many species are already experiencing problems, such as declines in their reproductive success and reduced size.
According to Dr Percoraro and other scientists, blue light also affects whales, and they are seeing more and more instances of whales dying.
It is clear that we are at a tipping point, Dr Michael B. Johnson, a NOAA scientist who specializes in ocean acidification, told the meeting.
“It’s very likely that the ocean acidifies, which is very likely, because the ocean is becoming increasingly acidic,” he said.
He also pointed to a 2012 study showing that the impact of blue light on the marine life of the Gulf of Alaska had become so severe, that the population of blue whales in that area had declined by about 20 percent.
One reason blue light has become such a major problem in the Gulf is because it is used to generate electrical signals, which are used by the electronics in many lights, such that they are able to adjust the brightness of the light emitted by a lightbulb to match the intensity of the electrical signals emitted by the light bulb.
The effects of this are being seen in some marine species as well, Dr Johnson said.
He said that this may be a factor in the loss of orcas in the Atlantic, where a particular region of the ocean had been badly affected by pollution.
When we talk about the impacts of light on marine life, we are talking about the fish that have to swim to surface.
They are the ones that are suffering from this,” he added.
“When we see a whale that has suffered from a health problem, we want to make sure that that whale has the opportunity to go to another part of the marine world and live, so that they can continue to live and reproduce. “
The impact on whales is particularly significant because whales are some of our most endangered species,” Dr Pereci said.
“When we see a whale that has suffered from a health problem, we want to make sure that that whale has the opportunity to go to another part of the marine world and live, so that they can continue to live and reproduce.
As we get more blue light into the ocean, that may be happening.
The more blue lights we have in the world, the more blue-colored lights will be visible to the eye, and we’ll see them in the water more often.”
Dr Pecorio said the problems would worsen as we have more and longer light hours.
And as light pollution gets worse, the impact on marine organisms will be even more severe.
At the meeting, NOAA Fisheries scientists spoke of the effects of the pollution on fish.
I’m talking about people who are using lights that emit more blue, Dr B.J. Johnson said, referring to the U.S. government’s efforts to reduce the amount of blue lights in the country’s electrical lights.
We’re seeing this really rapidly, he said, and the effect on animals is really clear.
If the government is doing anything to reduce these levels, then I would hope they would work to reduce those levels.
Dr. Johnson noted that the U-2 mission had flown over the Gulf for nearly 30 years, but he had not seen such a large impact on the sea creatures.
The U-4 mission is looking at a different type of pollution problem. “
We’re talking about a lot more fish that are being killed, and not just killer whales, but also humpback whales, which swim in the area, and sea lions, and a variety of other animals.”
The U-4 mission is looking at a different type of pollution problem.
The U-3 mission is working to reduce pollution on the ocean floor.
