New Exploration Into Blue Hole On Great Barrier Reef Brings Some Welcome News

3 min read

“The Great Barrier Reef is dead”.

This line has been thrown around the internet and the media over the last year. Partly to grab headlines but more significantly it points to the very serious and very real prospect that coral bleaching on the reef has killed up to 67% of the corals there. Without the corals, there are no fish. Without the fish, there are no predators. Without the predators, there is nothing.

It makes for some pretty grim reading, particularly as this situation is almost unequivocally our fault as a species. If the GBR is on life support, this news is certain to give those who care for its well-being (that should be all of us) a welcome boost.

Yesterday’s Blue Hole mission in the Great Barrier Reef. This Blue Hole has previously been explored and documented by geologists who suggested it could be even older than the famous Great Blue Hole, in Belize. It’s location is in one of the least explored parts Great Barrier Reef, over 200km from our home @daydreamislandresort . To get there we had to travel overnight for 10 hours and time the tides perfectly… Was well worth it! Inside the walls was similar to the site we explored a few weeks back, but this hole was deeper and almost perfectly circular. We dived down to just over 20m yesterday, before hitting bare sediment, that slowly sloped towards the centre. Again it was great to see big healthy coral colonies. Stay tuned for video footage of the coral within…

According to marine biologist, Johnny Gaskell, his team’s recent expedition to the world’s lesser-known but no less spectacular ‘Blue Hole’ has found a huge variety of ‘big healthy coral colonies’ within.

Posted on his Instagram, the Blue Hole exists at one of the most remote parts of the 2,300km long and could be even older since it’s formation than the world famous Dean’s Blue Hole in Belize.

The bizarre phenomena were created back during the Ice Age when the sea level was up to 100 metres lower and over time the limestone-based ground had been eroded away by glacial run offs, eventually collapsing into a sinkhole. Pretty cool no?

With successive ‘bleaching events’ in 2016 and this year, it had been widely reported that the GBR was soon to be referred to in the past tenths only but this new discovery ignites new hope that parts of this unmissable and colossal structure may yet survive the warming of the seas through climate change.

One thing is for sure, if visiting the Great Barrier Reef is on your Bucket List you’d better put it to the head of the queue.
