It is an injustice that turtles are blown up in the Gulf of Mexico because American oil companies choose a particular and inappropriate method for undertaking surveys before setting explosives.
If they did underwater, rather than aerial surveys, it would be difficult to ever justify blowing up biological diverse artificial reefs that are old spent oil rigs.
It is also an injustice when aerial surveys are undertaken to falsely conclude the Great Barrier Reef is more than 60 percent bleached when underwater surveys give a completely different and true assessment.
It is also an injustice that the Australian Institute of Marine Sciences had a perfectly good methodology for coring corals under-the-water and calculating an accurate overall average coral growth rates for the Great Barrier Reef, but then they changed the methodology and when the new methodology was shown to be flawed by Peter Ridd they did nothing about it.
Last week I was told a new and better overall coral growth rate will soon be some quality assurance published for the Great Barrier Reef –- but the methodology is not, and will not, be available for scrutiny, especially not to Peter, who was sacked by James Cook University for suggesting there needs to be some checking. Let me explain in more detail, including about the turtles.
Late last year I went to sea for a week with Shaun Frichette. I’m a biologist, and I was searching for 400-year-old corals that can be 10-metres wide and have annual growth rings, like tree rings, they are in the genus Porites.
Large and very old Porites corals used to be cored to calculate an overall coral growth rate for the Great Barrier Reef. Shaun came on the trip at short notice, wanting to know first-hand the state of the Great Barrier Reef; he had heard it was dying.
He was working as a volunteer at a turtle rehabilitation center on Fitzroy Island, which is just to the southeast of Cairns and part of the Great Barrier Reef Marine Park. Ten years ago, he worked as a deep-sea diver in the Gulf of Mexico.
Shaun got into deep-sea diving in his late twenties because he had developed a passion for environmental issues especially marine conservation.
At the time, he figured if an oil pipe was leaking on the seafloor it took a diver to go down and fix it, so he trained as a commercial diver and went to Louisiana.
He did lots of diving on the oil rigs as well as working topside on saturation systems and diver tending. His goal at the time was to become a saturation diver and live life ‘like an astronaut’ except on the seafloor.
To achieve that goal, Shaun knew he would have to put in years of hard work proving himself in the industry, but he never realized that the industry would meanwhile prove to care so little for life under the sea.
For example, the oil companies trained him to cut through steel with torches that burn at over 10 thousand degrees so that spent oil rigs could be dismantled safely – but instead, they sent him down to the bottom of the ocean to plant explosives because it was faster to decommission a rig that way.
The oil companies would send ‘turtle girls’ up in a helicopter to scout dolphins and sea turtles and if they gave the ‘all clear’ charges would go off and we would return to location. The problem was those oil rig platforms become like coral reefs after years of being submerged and the sea life around them is so biodiverse and special.
The turtle girls could only see 5 meters underwater on a good day so what I witnessed was horrific. Turtles cut in half, wounded dolphins and thousands of floating fish stunned from the explosions.
Something changed inside of me after seeing that and it’s altered my life path ever since.
Shaun quit and soon found himself back in California, in the High Sierra, at Lake Tahoe where he first learned to Scuba dive. He bought into a dive business doing boat salvage and dock repairs during the summer months – while volunteering for marine conservation projects during the winter months when the lake froze over.
The bushfires happened in Australia during the 2019-2020 ‘off season’ and after hearing news reports, Shaun volunteered as a firefighter and came to Australia. Covid hit, and so he stayed on. First helping with wildlife rescue, before traveling north to see the Great Barrier Reef.
I met Shaun in late November 2020 at a café in Cairns. It was the day before we set off with underwater photographer Stuart Ireland on a hurriedly arranged week at sea.
The plan was to look for, and film, a particular type of coral known as Porites with annual growth rings, like tree rings, so they are potentially a time capsule of the ocean’s climate history.
We wanted to find the oldest and largest of these corals that AIMS used to core, all the way to Myrmidon reef where there was once an extensive coral coring program.
Some of these Porites corals are huge. Just last year I measured a healthy Porites coral seven meters in width and three meters high, at an inshore reef called Pixie Reef just 40 kilometers to the northeast of Cairns.
This is a reef that is classified in the peer-reviewed literature as one of the very worst bleached (more than 60%), yet I’ve struggled to find any bleaching at all at that reef.
I’ve also seen Porites large and healthy, in fact, dozens of them, in Bowen Harbour where all the corals are meant to be dead from global warming and ocean acidification and poor water quality – yet they are very much alive, or were, when I was there in April and then August 2019.
Just three weeks ago at Lady Elliot Island to the east of Bundaberg, I found a Porites that was 4 meters in height and so healthy.
I asked the local divers if it has ever bleached and I was told by an old guy who has worked on the island for thirty years that it once went blue in color after a cold snap, that was a few years ago, but that it has never bleached.
We are repeatedly told, most recently by the Australian Academy of Science, that most (somewhere between 50 and 99%) of the hard corals of the Great Barrier Reef are now dead, yet this is not my experience as someone who snorkels and dives. I have seen very large and dead Porites, but not often. Perhaps as often as I see a dead tree in my favorite national parks.
One of my frustrations with the official reporting on the health of the Great Barrier Reef is that much of it is based on aerial surveys. Not by turtle-girls, but by a university professor.
Like the aerial surveys in the Gulf of Mexico, the surveys might be best described as convenient. They are certainly not scientific; despite being published in peer-reviewed scientific journals.
The fly-past aerial surveys give the impression they are quantitative and claim that the entire Great Barrier Reef is more than 60% bleached, but the only numbers actually recorded by Professor Terry Hughes looking out the plane window are rankings of 1, 2, 3, or 4 based on his impression of the state of the corals from that high altitude.
At 150-meters altitude, he might be just able to just make out the very large Porites at Pixie Reef on a good day. I sent my drone up and took photographs at 40 and 120-meters altitude of that monster coral that measures 7 meters in width on 25th November 2020.
It appeared white and possibly bleached from the air. Yet under the water and up-close it was beige in color, with healthy zooxanthellae. There was absolutely no bleaching.
I gave the coral a score of D3 on the University of Queensland Coral Watch Health Chart (www.coralwatch.org). But who else actually goes to check?
To lament the dying Great Barrier Reef is politically correct, to question this is to risk being labeled a climate change contrarian.
Yet my experience over 50 years of diving at the Great Barrier Reef – since January 2020 I have had the opportunity to scuba dive almost the entire length of the Great Barrier Reef from the Ribbon Reefs to Lady Elliot Island including dozens of reefs in-between – is that they are still exceptionally diverse and beautiful.
The 2016 bleaching event was reportedly the most severe on record, particularly in the northern section including at the Ribbons Reefs, yet most of the reefs appear to be fully recovered.
When university professor Peter Ridd explained the extent of the misrepresentation back in 2015 in an email to a News Corp journalist, specifically that there are still healthy live corals in Bowen Harbour, while calling out a colleague claiming otherwise, he was reprimanded by James Cook University.
To publicly demand some quality assurance of claims the reef is dead and dying is professional suicide. The professor’s dismissal from James Cook University in 2018 –- essentially on the basis that he broke the enterprise bargaining agreement by being un-collegial –- has been appealed all the way to the High Court of Australia, with that hearing scheduled for 23rd June 2021.
Peter’s case is focused on issues of freedom of speech. Not because Peter does not care about the truth, but because the only way we might be able to get to the truth about the health of the Great Barrier Reef is if he can put his evidence.
He needs to first have the opportunity to be heard beyond the academic journals that are behind paywalls.
Back in 2013, Peter published an analysis of how the Australian Institute of Marine Sciences has changed the method they use for coring the Porites corals to calculate an average growth rate for the Great Barrier Reef.
The method has essentially been changed for convenience. The data then showed a drop after 1990 that is conveniently consistent with the narrative that the Great Barrier Reef is dying –- never mind that the new method is flawed.
In the 2013 research article in Marine Geology, Peter explains that firstly there are instrumental errors with the measurements of the Porites annual growth rings undertaken in the early 2000s.
This is especially the case for the last layer at the surface of the coral, which was often measured as being much smaller than the reality.
This created an apparent drop in the average calcification for the corals that were collected in the early 2000s – falsely implying a recent calcification (growth rate) drop.
Secondly, an ‘age effect’ was not acknowledged, specifically, the coring program in 2003, 2004, and 2005 focused on smaller colonies, many just a few tens of centimeters in diameter.
In summary, while coring in the 1980s focused on large old corals and their growth bands were accurately measured, coring in the early 2000s focused on small young corals and when some of the measurements were checked they were found to be in error.
Yet the two datasets (from the 1980s and early 2000s) were spliced together, and wholly unjustifiable assumptions were implicitly made, but not stated – in particular, that there is no age effect on coral growth.
Coral growth rates are a potential measure of reef health, but the methodology needs to be consistent. When the data to 2005 is filtered for only the largest and oldest Porites corals, it shows an increase in calcification rates (coral growth rates).
