Corals That Don’t Exist Thriving In Real World

Peer-reviewed science, this time about coral reef health, is again being contradicted by real-world evidence.

In December 2015 Peter Ridd, then a physics professor at Australia’s James Cook University, contacted a journalist, writes Donna Laframboise (via Climate Change Dispatch).

Researchers affiliated with his own institution, he said, were misleading the public about the Great Barrier Reef.

As an example, Ridd cited photos taken approximately 100 years apart near Bowen, a community of 10,000 on the Australian coast in the vicinity of the Reef. These photos tell a stark story: previously vibrant coral expanses are now desolate wastelands.

Ridd complained that this pair of photos was spreading across the Internet. They were appearing in official reports and news stories.

Even though the 1995 paper in which they’d first been published had cautioned against viewing them as evidence the Reef was in “broad-scale decline,” that’s exactly how they were being used.

Ridd supplied the journalist with recent photos from the same area. These showed healthy, abundant coral.

A few weeks later, matters took another turn. Nature published a paper titled ‘Historical photographs revisited: A case study for dating and characterizing the recent loss of coral cover on the inshore Great Barrier Reef’.

The authors said they’d found “very little sign of coral re-establishment” during a visit to Stone Island in 2012, approximately a mile offshore from Bowen. In their words:

At Stone Island, the reef crest was similar to that observed in 1994 with a substrate almost completely devoid of living corals. [bold added by me (DL)]

Ridd knew this wasn’t the case. As he’d explained to the journalist:

any decent marine scientist or boat owner around Bowen, could have told you that there is lots of coral…and that it is spectacular. It was always a very unlikely proposition that this area had suddenly lost all its coral. [page 22]

Yet one of the most reputable scientific journals on the planet had just declared otherwise. The real world and the scholarly record were in stark conflict.

So let’s fast forward three-and-a-half years. Late this summer, Australian scientist Jennifer Marohasy enlisted underwater cinematographer Clint Hempsall and coral reef expert Walter Starck. Together, they investigated the waters near Stone Island firsthand.

    As the article later explains, the journalist Peter Ridd contacted went on to stab him in the back, in terms of his employment at the university.

    Just as a point of interest, the actual area shown in the old photographs is actually shown on Jennifer’s film and it still looks pretty devoid of coral. Seeing as it seems fairly obvious that people have been WALKING on this area for a hundred years, I’m not really surprised that the coral hasn’t recovered in this particular area from what it was in the early 20th century. But Jennifer’s film demonstrates it’s thriving just offshore. Climate change obviously hasn’t got to those bits of the reef yet!

    Tried to copy video at present URL but didn’t work. Check scene at 1.24. Exactly the same as photos in the study.

    From JM’s blog article:
    The most damaged of the eight reefs that we snorkelled was at Middle Island, with much of the reef to the south-west of the island reduced to rubble by Cyclone Debbie which struck in early 2017.

    Great Barrier Reef annual mass coral spawning begins

    A mass coral spawning has begun on Australia’s Great Barrier Reef, with early indications the annual event could be among the biggest in recent years, local marine biologists said Sunday.

    Buffeted by climate change-induced rising sea temperatures and coral bleaching, the world’s largest reef system goes into a frenzy once a year with a mass release of coral eggs and sperm that is synchronised to increase the chances of fertilisation.

    Marine biologist Pablo Cogollos, from Cairns-based tour operator Sunlover Reef Cruises, said the first night of the 2019 spawning was notably “prolific” in a positive sign for the under-threat ecosystem.

    “There was three times the volume of eggs and sperm compared to last year, when the soft corals spawned four nights after the full moon and it was deemed to be the best coral spawn in five years,” he said.

    The natural wonder, which has been likened to underwater fireworks or a snowstorm, occurs just once a year in specific conditions: after a full moon when water temperatures hover around 27 to 28 Celsius.
