Coral spawning is visible from the air | Vimeo Biopixel
From the Bolt Report, Professor Peter Ridd points out how little we know about the history of bleaching of corals. Corals have been around for 200 million years, but we only discovered coral bleaching and coral spawning in the 1980s, even though the synchronized slicks are so vast they are visible in satellite shots. When discussing whether the Great Barrier Reef going to die he says “everything that I look at says the opposite”.
Professor Peter Ridd (James Cook Uni)
“Terry Hughes is on record as saying Bleaching is a new phenomena — it never happened before the 1980s. It is an absurdity –we just discovered it to science in the 1980s.
There is another thing the reef does that is equally spectacular — and that’s coral spawning — three days after the full moon in November every year the whole barrier reef, every coral virtually, releases egg bundles that float to the surface and from the air we can see these massive slicks of coral spawn on the surface. It’s incredible. we only discovered that in 1982.
Are we really suggesting that “it never happened before” that corals only discovered sex in 1982?
Of course, it’s been going on for 200 million years.
Yet, when we discovered coral bleaching in the 1980s that its anthropogenic, it’s bad, it’s us…
For background, coral spawning happens at night, the timing is tied to full moons, though happens in different months on different reefs around the world and can be confused with algal blooms.

“Usually about a half an hour to a couple hours before spawning, you can start to see the egg or sperm bundles starting to be formed underneath the polyp, and the tentacles tend to contract,” says Dr Peter Harrison, director of marine studies at Southern Cross University and a member of the research team at James Cook University who discovered the mass coral spawning phenomenon on the Great Barrier Reef in 1981.

Your link doesn’t work!
The real understanding of coral spawning was only recent 1980’s
The 1st identification was by Siro Kawaguti in 1939!
Observations only, but Siro was the precursor to the later detailed research!

No don’t hold your breath… in the old days we used to pray for the wind to breath over the city to blow the inversion layer trapping the stale heat away…. There were hourly updates at times on the TV to confirm if or when the wind would come to our rescue and blow the hot air trapped by an inversion layer over the masses away…. 🙂
30
Once upon a time, back in my youth, everyone, even the cat next door did know that it got hot in the city, a growth resembling coral with its high rise buildings etc, because of an “inversion layer”.
Amazing how quickly everyone forgot about hot days caused by inversion layers…and that they behave like a greenhouse over a city trapping the heat..
http://geography.about.com/od/climate/a/inversionlayer.htm
Use of the term “inversion layer” has completely disappeared from the weather mans/woman vocabulary..
In the first days of coral bleaching, there were many reports about it being caused by nutrient runoff from farming and the like…that was the meme way back then…

LoL the first link was mistakenly more recent and is not from the good old days (My Mistake) and shows the gentleman got a huge grant, but then i noticed in the beginning of the piece that it is said that the coral would be better able to cope with global warming if the water quality was better and hey presto,,, Grant Funding for mentioning GW lol

Say it isn’t so. 97% of climate scientists say corals don’t live in warm water.

Not only the warm water but more acidic as well , I predict using James cook data and models that there will be no more coral left unbleached in two years unless you send me huge amounts of money .
272
That may unbleach James Cook bank accounts but what effect on the reef?

Er, how do you stop coral forming? A few years back divers visited the crater blasted out by the Yanks’ (largest ever) nuclear blast on Bikini Atoll and…you have to guess what was flourishing there. Go on, warmies. Guess.
Want to kill coral on a broad scale rather than in the damage-prone fetish spots? Have an ice age. You might slow it down…but that stuff is like the lantana.

Now that’s a physicist speaking. Gravity did not exist because of Newton. Radioactivity was not started by Madame Curie. Cricks and Watson did not invent the double helix DNA. However Xerox did invent the mouse.
In the last century mankind has invented a great number of things like jet engines and the internet, but we did not invent coral, nor care much about it until James Cook ran into it and he wouldn’t have been thrilled by the lovely colours. You have to assume that Kangaroos, coral and gravity and the planet can exist quite happily without us. Who would think coral had a sex life? Maybe it is just pining for the Fjords?
As for CO2 making the planet disastrously warmer, that isn’t true, isn’t likely and simply a wild theory but somehow it controls the behaviour of coral? I know crazy religions which make more sense. More Climate Scientology.

Or at least the integrated screen and mouse windows like system as invented by Xerox Palo Alto laboratories where Steve Jobs first saw it.

And the Antarctic Ozone Hole was “discovered” in 1984.
In the 1950s, until it’s “discovery,” it was known as the Antarctic Ozone Anomaly or just the Antarctic Anomaly.
CFC prodution didn’t ramp up to any real quantities until the late 1970s. But Mt Erebus started its present on-going eruption in 1972, emitting 1000tons of Chlorine per day.
172
One of the worlds top ionospheric scientist told me personally that ozone holes are quite normal and been around for as long as theres been an ionosphere. That was about in 1986 when i was a research assistant. Thats about when the panic started and a really good refrigerant was banned for another scientific fraud, the CFC scare. Wasnt long after that they dreamed up how to ramp up the attack on hydrocarbon fuels…and here we are.
131
That ozone hole explanation does not make sense. If CFC’s were the problem, why is the ozone hole in the Southern Hemisphere?
Only 2% of people live South of the Tropic of Capricorn. Australia, NZ, South Africa, Chile and Argentina and little else. The rest live largely in the Northern Hemisphere but they don’t have a hole in their Ozone layer? So it is now cheaper to buy a new Chinese refrigerator or airconditioner and let all the CFCs into the air than pay $1K per kg for new gas. Once again Western democracies pay and China benefits.
Why do the Greens love communism? They were supposed to love the environment, but as Tony Abbott said, it was just socialism masquerading as environmentalism.
152
So true..I thought that at the time.

TdeF said:
Maybe it’s because the Arctic has special ozone? 🙂
You’re right, it doesn’t make sense. Neither does the CFC to Free Chlorine to ozone depletion make much sense.
There’s a lot more ozone up there from other sources.
The Arctic gets ozone holes. The last one was March 2011 (?). It seems to be connected to very low air temperatures around -50oC. That’s a normal springtime temperature at the South Pole so the Anarctic Hole is also “normal.” The Arctic air dropped to around -50oC in the middle of March 2011 (a pretty cold winter in the NH) and there it was.
The Antarctic is a desert. Only mad scientists winter over and that could be less than 100 people. So it’s not only a desert but effectively an unpopulated desert.
The Ozone Hole appears to be fully contained in the Auroral circle at each pole (scroll down the page linked … it’s on the LHS). The size of the auroral circle seems to depend on the solar wind speed/strength. Considering the energy being dumped into that column of atmosphere from the SW, there doesn’t seem to be any impediment to the ozone level in that column varying.
Looking at NASA’s Ozone-Watch pages the variation in area of the ozone hole is not particularly large. (To NH Arctic page. Nor is the variation of ozone quantity. Business as usual.
What makes the “science” about ozone holes suspicious is the poor prediction. A large hole was projected ) for the Arctic in the NH spring for this year. It didn’t eventuate.
A few years ago, a lot of volcanic released chlorine and other “ozone depleting” chemicals in a large plume was heading for the Arctic. NASA issued a warning about a possible Arctic ozone hole. They were wrong. It didn’t happen.
Shades of climate model predictions …ah projections since 1990 … 🙁
It translates into erroneous articles such as this one.
But Wait! There’s More. According to modellers, the ozone hole is “is showing signs of healing.” The graphs at ozonewatch don’t show that so much. The downturn could just be the current (low) solar activity.
But Wait! There’s still more! The Montreal Protocol was created in 1989, close to when the CFC patents were about to (or had) run out. Earlier this year — 25 or so years later, CHCs, the replacement refrigerant, have been added to the Montreal Protocol. Perhaps their patents are about to expire.

there’s a lot more ozone up there from other sources

Yes, Xerox PARC didn’t really have an plans for their mouse/windows/icons invention and it was more or less languishing in their labs.
It took a visionary like Steve Jobs to see the potential for making a few bob.
This is not unlike CO2.
It was languishing around in the atmosphere with no real plan until Maurice Strong came along.
Just like Jobs, Maurice Strong saw a way to make money out of an innocent and minuscule amount of a natural gas.

Also there are corals in much hotter water, but warmists are always looking to explain why they are wrong
“In Eritrea the coral is not only surviving these warm temperatures but is thriving. It is thought that there might be a heat resistant algae that exists in coral in the Red Sea. If this algae can be extracted, scientists believe there may be a way of saving coral around the world from bleaching.”
They just refuse to accept that after millions of years animals can adapt and have done so through 200 million years. Humans can but apparently coral polyps are just not smart enough, according to much smarter scientists who really need research funds to survive. Given that homosapiens are only 100,000 years old, I would back the polyps to be around much longer and they did survive the dinosaurs, mass extinctions and the movement of the continents. We have yet to get through the 21st century. I wonder if coral polyps worry about us?
183
Are you aware that there are different species living in different places?
21
and another thing… how long have these polyp species been around? Lots of phylogenetic studies about that suggest some are of the same order of Magnitude as humans and some extremely recent. Although it does not surprise me, you are not comparing alike taxa. Instead of humans you might need to consider primates and even, arguably, vertebrates vs polyp.
Alternatively, admit that you don’t understand evolution and do some reading rather than assuming that your top of the head thoughts are correct.
21
… coral spawning happens at night, the timing is tied to full moons …
From what I remember of my youth, night time spawning, in the light of a full moon, is not a phenomina restricted to coral.

Watching the Left-Green war against Western industrial society and the destruction of our power grids built over the last century or so leaves me nostalgic for the history of the Industrial Revolution that made our Civilisation.
I am watching on TV now the following program. You might want to check it out.
I just discovered the episodes are available on YouTube! Search “How Britain Worked”.

The way I always thought coral worked, was that it was a thin skin of living corel stood on the dead structures of earlier corels. The ocean is full of creatures and plants looking for a home. Thus a ship that sinks at the right spot, quickly gets colonised. A bleached reef might be temporarily unsuitable but would quickly look like prime corel real estate.
60
Yes, but it is the Armageddon scenario the Greens want. Cities drowning. Polar bears drowning. Coral Polyps getting slightly warmer and not able to cope? Tragedy and all the fault of the motor car and the consumer society and democracy.
We must not forget the original Global Warming scenario, 0.5C in ten years so by Green arithmetic, +5C in 100 years and the end of the world. Now that 30 years have passed, we are being told that this year is the warmest ever, they hope. I thought we were supposed to be +2.0C warmer by now?
However to keep this going, the warmists have to prevent any year being colder than the previous. That must take some serious homogenizing by the usual suspects. If the world gets colder, even by 0.01C, no one will believe Global Warming. So fearing the worst, we now have Climate Change, except no one understands what that is, which is the idea. It seems a catch all for every change, even coral bleaching which obviously is someone’s fault. It can’t be natural. Can it?

But did you see The Oz this morning and the long articles on how the progressives hard left greens and academics in Sydney and elsewhere are bypassing schools just down the street because they are full of the ethnic dark skinned kids of recent immigrants and are taking their precious little white skinned bundles across town to nice expensive schools that are populated by mostly white skinned pupils from well endowed white skinned parents.
The same progressive left green high income inner city latte sippers and academic types who are demanding that the government let in any riff raff from anywhere into Australia otherwise if we don’t, the “World will see”that we are a racist nation devoid of compassion.
Just another out of an endless litany of outright hypocrisy and hubris from the progressive left of “Do as I say, Not as I do” and as for those immigrants, sending our kids to a school where our little dears might be contaminated by them , No way! “Not in my backyard”.

I wonder what the ‘red thumber’ is hoping to achieve? I’m using the singular for convenience. Clearly whoever it is hasn’t got the knowledge or courage to enter into a discussion.
Perhaps it’s a feeble attempt to discredit the website, by trying to convince visitors that someone very knowledgeable has read what has been posted, and considers that the posting is nonsense?
Let me guess. Young, didn’t do too much science at school, believes what the media, Al Gore and the rabble at the ‘Skeptical Science’ website say, and isn’t inclined to question or think for himself (I doubt it’s a woman) or consider alternative arguments or data.
80
Over this last year or so, the GBR propaganda has been quite relentless from their ABC and friends.
I wonder how much tourism income has been lost as a result.
The point being, of course, that if you’re operating a reef snorkelling boat for foreign visitors, you’re going to take them to the nice places on the reef in any case.
Even if there are bleached patches close to your base, of course you aren’t going to take them there.
People go to Pompeii to see the ruins etc.
No one ever worries about the other probably 95% of Pompeii that no longer exists at all.

An ‘evolutionary biologist’ who does not believe in survival of the fittest and evolution? That is from a change so small that it is hardly detectable except with modern instruments? Already deadly climate change and widespread extinctions of 50% of species from an alleged change of 0.8C in an average over 100 years? Absolute nonsense. I cannot believe the author has any qualifications in this field.
70
He is, quite simply, a liar.
It’s a lie that only non-scientists and the extremely unobservant will believe, but the intent to deceive is plain. “Local extinction” is not the same as species extinction, not even nearly!
I shouldn’t be shocked when I see a respected scientist do this, after all this time, but somehow I still am.

The Bolt Report? Classy.
A good chunk of the GBR died during the 2016 Great El Nino. Oceans are warming so another chunk will die during the next Great El Nino. It all depends on how well the reef recovers between the El Ninos.
311
Warning: Brain-storm of questions:
For how long, have El Nino’s been occurring? What is their frequency? How long does an average El Nino last? At what water temperature does bleaching occur? What is the optimum temperature range for coral to thrive? What is the recovery rate, after bleaching occurs? What free-swiming preditors does living coral have? How do populations of preditors vary, in relation to in the reef? What part of the frequency spectrum causes bleaching? What part of the frequency spectrum encourages coral growth? What other potential causes of bleaching were considered and researched in relation to the 2016 bleaching. Can bleaching be reproduced in the laboratory, and under what circumstances?
I may have more questions, after my next coffee.

ENSO and the climate as we know it began around 1980, along with GOES-4 sat, polar vortices, lake effect, supercells, superstorms and Do That To Me One More Time by The Captain & Tennille.
Before that we had…stuff happening. Like the globe-wrapping heat/drought of the 1870s, the cooling/drought of the late 1630s that broke the Ming, the East Indian drought that nearly killed Sydney in its infancy; the serial monsoon failures of 1756-1768 that brought down several kingdoms in Asia while killing tens of millions…

Harry Twinotter,
Just two things,
1. If the corals are dead(?) by what mechanism do they recover? (Resurrection?)
2. How many times in this coral reef’s time on earth has this happened before?
Given that we’re very ignorant of coral reefs complete life cycle, there is nothing to say that coral bleaching is not a natural cyclic event in the life of the coral.
112
I find it hard to take the vapourous hand-wringers seriously.
The thought processes seem to be:
“OMG! there is an effect that I haven’t noticed before. So it must be something new, and the result of a chanage!
What has changed recently?
I know! There were three more skiboats over the reef this year, compared to last year, so the change must have been due to them!
We need to ban all skiboats from near the reef.
Better still, and since boats and ships burn fossil fuels, and polute the reef, we need to put a hefty tax on all fuels used for maritime activities!
Having a tax on maritime fuels should save the coral.
112
tomomason.
“1. If the corals are dead(?) by what mechanism do they recover? (Resurrection?)”
The dead coral gets recolonized by new coral.
“How many times in this coral reef’s time on earth has this happened before?”
No idea. What is the point of your question? The GBR is not one gigantic organism, it is a community of separate organisms.

Every kid growing up discovers sex at some point. And for a while some of them do act as if they’re the first in the world to make that discovery. But then reality finally takes hold and they realize they aren’t the first to know about it. I wonder why the science world always thinks that just discovering something means it just started. The list seems long: warming and cooling of the Earth; melting and refreezing of Arctic ice; the “ozone hole”; bleaching of the Great Barrier Reef… …and… …so-on.
I wonder when they will wake up.
90
That’s a good observation, Roy.
In my part of the world, schools have tended to rebrand “history” as “social studies”. This makes it more relevent to to becoming a citizen, but has the side effect of shortening the time-span of history that is addressed by the curriculum.
So I am working with very bright people, who know how to get business done in the real world; but have little understanding of what has worked in the past, and what has proven to be disasterous.
They get annoyed when I start asking “what-if” questions. And then they get even more annoyed when they realise, that they don’t have the answers.
“Those who do not understand history, are doomed to repeat it.” Variously, Edmund Burke or George Santayana.
111
I could postulate a reason for the mindset that says I just discovered it, thus it just started. It may be worthless or it may explain something about humans. The ever present need for recognition tends to demand that you get widespread attention for your discovery and usually the only way you can get that kind of attention is if you can tell everyone they have a serious problem and the worse the problem the better. There is probably a built-in bias in this direction something like confirmation bias.
Now, which is the easier scenario to sell, it’s been there possibly for hundreds or thousands of years but it’s still a problem or, it’s brand new thus it really represents trouble that we need to address immediately?
I think that question answers itself.
And if that’s not it then I don’t know why it happens but as you point out, it is rather easy to see when it pops up.
30
I remember being on the Great Barrier Reef in the early ’80’s….
I sincerely hope it wasn’t anything that I did….

It doesn’t matter, John.
Whether it was something you did or not, the thirty-something’s will blame you for it.
61
What truly amazes me is that an animal that lives almost exclusively in the tropics – certainly the case for reefs near sea level – is so vulnerable to luke warm water ??
I think there mus be some other explanation – after all some corals are exposed to the sun at low tide and somehow survive.
80
” I wonder why the science world always thinks that just discovering something means it just started.”
It is most common in climate. When a climateer sees an iceberg calve from a glacier, it is the end of world, because he has never been there before to see it.
If the snow slides off his roof he should be happy. If it was not sliding off he might experience a real collapse.
The GBR is used as a poster child for GW as the sea ice and glaciers, but it can turn around very fast. Antactic sea ice was not mentioned untill it this year reduced more than normal.
By the way, is there any more corals to die, haven’t they died several times in the latest 20 years. Amazing there are some left that can still die.
60
True science is way out of reach,
For alarmists who prattle and preach,
That ’82 was the year,
Which confirmed their worst fear,
That man caused the corals to bleach.
60
In 1972 I did my first cruise of the reef in my yacht. I left Sydney in April, & started heading back when the northerlies started in October.
I was talking to an outer reef line fisherman I’d got to know at Middle Percy Island, & complaining about the brown & yellow scum on the water in huge areas. The yellow was not too bad, but the brown stained the paint anywhere it was allowed to dry.
This bloke from Mackay was about 45 years old, had been fishing the outer reef since he was 14, so did not have much science education.
However he told me it was coral spore, & explained how coral all released their sperm over 2 nights.
Isn’t it interesting that this was a well known phenomena to the lowly educated fisherman, but academics had never heard of it.
Just an example of how insular, & poorly informed on most things they are. Obviously to them the lifetime knowledge of a bright, but not well educated fisherman would never be of use or interest to them. Perhaps they would be better informed if they got out more.
110
An academic friend of mine defines Academic Specialisation as; the manifestation of people, trying to learn more, and more, about less, and less.

Can I suggest that the aboriginal people knew about this many thousands of years ago.
What the fishermen and earlier people didn’t do was systematically measure the timing, water chemistry, cellular metabolites, genes etc that scientists do to try to understand how the whole system works. Maybe Hasbeen hears media reports of scientists studying these things and finding out new stuff and misconstrues this to mean that they “had never heard of it” prior to their study?

Gee Aye, I ran a fleet of tourist boats in the Whitsundays. I had considerable dealings with the Marine Park people, AIMS & James Cook. I know damn well how poorly informed most of them are, & how little they ever actually do on the reef.
Playing with synthetic environments in tanks on the mainland, like computer models of water, is more their speed.
I took the entire board, & a number of researchers of the marine park out to Hardy reef before it was gazetted. I had one fool “scientists” telling me we didn’t have long before the crown of thorns put us out of business.
When I told him that I & my staff had only found 2 of them in the area in the last 6 months, he told me we must not know what they looked like.
My offer of transport to & accommodation on the reef, so he could look himself was rejected.
Useless garbage, wasting taxpayer funds.
We had a number of PhD students we gave transport & accommodation to, who made sense, it must have only after they graduated they became such dick heads.

One other thought. Don’t you remember the big announcement when the Townsville lot told us of their momentous discovery of this spawning event? If not you must have been sleeping under a log, it went on for days.

Save the Corals? Its always save something with the usual crowd of scientific illiterates!
Why is it that so many things now need saving, but even when ignored, seem to thrive.
And all this is over how many degrees of warming?…. 0.7c in about 130 years, most of which is natural.
And if not, then the hysterical activists should then hold their breaths as to not increase thy problem they claim exists, along with their CAGW high priests jet setting around the globe to attend all their climate junkets!
Or are the rules different for the true b’lver brethren, especially the pontificators of this CAGW ratbagism?

“Bleaching is a new phenomena — it never happened before the 1980s.” – Terry Hughes.
No reference to this quote is provided. So it could be a misquote.
I did find some quotes that imply MASS coral bleaching was virtually unknown before the 1980s.

Apologies if someone has already corrected this but corals have been around a lot longer than 200 million yrs. In fact corals were abundant throughout the Palaeozoic Era, between 545 and 251 million years ago. A great example are the Devonian Reef Complexes in the Canning Basin WA. Rugose and tabulate corals became extinct at the end of the Palaeozoic (251 mya), after which the modern reef-building corals, or scleractinians, arose early in the Mesozoic Era.

so what?

Oh sorry just trying to provided you with factual information, but then reading your comments elsewhere what more could I expect from a total knob/nob (take your pick on the spelling variation)

OK… does your information mean anything in the context of this discussion. Please let us know.

Would have thought that was pretty obvious really, but then …
1) Correct the information on how long corals have existed on this planet ie. twice as long as Peter Ridd had stated. I think it was Mark Twain who said “Get your facts first; then you can distort them as you please”
2) Gee Aye boy they have survived a few worrying times in their long history so I don’t think a small shift in water temperature is going to have much impact in geological terms.
Now you can go and do a little research of your own and see what a broad range of conditions corals can and have survived in – your end of term assignment or is your special school done for the year?
