Teams find cancerous lesions on the scales of about 15% of the coral trout in Australia's Great Barrier Reef, which is under an ozone hole.

Approximately 15% of coral trout in Australia's Great Barrier Reef had cancerous lesions on their scales. In that regard, they resemble Australians who live on land — 2 in 3 people who live down under will be diagnosed with skin cancer before the age of 70, the highest rate in the world. It's probably no coincidence that Australia is under the Earth's biggest hole in the ozone layer.

Scientists from the Australian Institute of Marine Science were near the Great Barrier Reef conducting a survey of shark prey, predominantly coral trout. They kept seeing strange dark patches on the normally bright orange fish, and for help they turned to another research team from the University of Newcastle in England that was studying coral disease in the area.

The researchers were unable to determine why the incidence of melanoma was so high in these fish. Sweet said it was probably not a coincidence that the cancer occurred in the Great Barrier Reef, which sits under the outer reaches of the ozone hole centered over Antarctica. That greatly increases the area's exposure to harmful ultraviolet radiation, which can lead to cancer-causing mutations in DNA.

Ozone hole UV impacting marine life: study

Ultraviolet radiation has caused a steep increase in deaths among marine animals and plants, according to an international team including scientists at the Oceans Institute of The University of Western Australia.

The marine life most affected by UVB are protists (such as algae), corals, crustaceans and fish larvae and eggs, thereby affecting marine ecosystems from the bottom to the top of the food web.

The effects of ultraviolet radiation detailed in this study mainly affect organisms growing near the ocean surface, such as eggs and larvae of invertebrates and fish, which are exposed to very high UVB levels.

So, humans can't f*ck up our home, eh?

We will be seeing more and more of this in all animal species..the u.v. index used to Max out at 10. Now they changed it to a Max 15 and it is like 12 or13 every single day throughout all of northern u.s. getting worse daily...

Naw, its from all the shit we dump in the water.

Hell the skin cancer rate supposedly went up here when everyone started using sunblock.

Get out in the sun.

Don't burn, but a good tan is the best protection, or so I've heard.

Humans get used to amazing things through exposure...

No.

Chlorofluorocarbons and ozone

Many people have heard that the ozone hole is caused by chemicals called CFCs, short for chlorofluorocarbons. CFCs escape into the atmosphere from refrigeration and propellant devices and processes. In the lower atmosphere, they are so stable that they persist for years, even decades. This long lifetime allows some of the CFCs to eventually reach the stratosphere. In the stratosphere, ultraviolet light breaks the bond holding chlorine atoms (Cl) to the CFC molecule. A free chlorine atom goes on to participate in a series of chemical reactions that both destroy ozone and return the free chlorine atom to the atmosphere unchanged, where it can destroy more and more ozone molecules. For those who know the story of CFCs and ozone, that is the part of the tale that is probably familiar.

The part of the story that fewer people know is that while the chlorine atoms freed from CFCs do ultimately destroy ozone, the destruction doesn’t happen immediately. Most of the roaming chlorine that gets separated from CFCs actually becomes part of two chemicals that—under normal atmospheric conditions—are so stable that scientists consider them to be long-term reservoirs for chlorine. So how does the chlorine get out of the reservoir each spring?
Polar stratospheric clouds and ozone

Under normal atmospheric conditions, the two chemicals that store most atmospheric chlorine (hydrochloric acid, and chlorine nitrate) are stable. But in the long months of polar darkness over Antarctica in the winter, atmospheric conditions are unusual. An endlessly circling whirlpool of stratospheric winds called the polar vortex isolates the air in the center. Because it is completely dark, the air in the vortex gets so cold that clouds form, even though the Antarctic air is extremely thin and dry. Chemical reactions take place that could not take place anywhere else in the atmosphere. These unusual reactions can occur only on the surface of polar stratospheric cloud particles, which may be water, ice, or nitric acid, depending on the temperature.

These reactions convert the inactive chlorine reservoir chemicals into more active forms, especially chlorine gas (Cl2). When the sunlight returns to the South Pole in October, UV light rapidly breaks the bond between the two chlorine atoms, releasing free chlorine into the stratosphere, where it takes part in reactions that destroy ozone molecules while regenerating the chlorine (known as a catalytic reaction). A catalytic reaction allows a single chlorine atom to destroy thousands of ozone molecules. Bromine is involved in a second catalytic reaction with chlorine that contributes a large fraction of ozone loss. The ozone hole grows throughout the early spring until temperatures warm and the polar vortex weakens, ending the isolation of the air in the polar vortex. As air from the surrounding latitudes mixes into the polar region, the ozone-destroying forms of chlorine disperse. The ozone layer stabilizes until the following spring.

nah, it would not have anything to do with them blowing holes in the upper atmosphere back in the 60s with nuclear bombs in space . . .

nah.

or all the ionospheric heaters boiling the ionosphere

I'd be more inclined to go with pollution.

This is really shocking, about the fish, especially since the ozone hole is mainly a long way SOUTH of the Great Barrier Reef.

Americans have no idea what it's like in Australia.

In Sydney, I would get burned within 20 minutes.

When we moved to Melbourne, which is 12 hours south of Sydney, and a lot closer the ozone hole, I was shocked that I got burned within just FIVE minutes.

Now I'm in Florida, I can stay at the beach uncovered for over an hour and just get a nice tan.

they need to take more fish oil!

83804, you appear to be knowledgeable or at least know where to look for pertinent data, so I have to ask this of you.
Regarding ozone layer pollution, SF6 (sulfur hexafluoride) use has been heavily restricted for many years. Since I work in an industry that uses the stuff, or at least tries to, I ask the question. How is it that this very heavy gas can accumulate in the upper atmosphere? Seems to me the stuff should sink, not rise.
I don't know, so just asking.

Maybe its just radiation. It could be fish that went thru Fukushima in their migratory pattern.
