“Calls for Barrier Reef to be declared disaster area”

Cyclone Hamish [maptype=G_SATELLITE_MAP;gpxview=all]

According to the ABC news website, a number of people including the Queensland Sea Food Industry Association are calling for the southern half of the Great Barrier Reef to be declared a ‘disaster zone’. Reports from the Great Barrier Reef Marine Park Authority suggest that >50% of the reef was affected by cyclone hamish, and reports from the commercial fishing operators say that in the wake of cyclone, most commercially viable fish stocks have all but disappeared:

“Half the reef has been completely overturned from Bowen South. It’ll affect tourism, it’ll affect certainly commercial fishers – about 50 per cent or 300 jobs are at risk with 30 guys put off yesterday,” he said.

“There’s just nothing left out there to fish on.”

He says the damage is having a similar effect to Cyclone Larry’s destruction of banana farms three years ago.

“We’ve had our boats out there working this week for the first time after the cyclone and people with 20 years experience can’t recognise the damage being done,” he said.

“Their catches where they’d catch 150 fish a day have been down to five fish a day.”

The Department of Primary Industries says such a disaster declaration would be a first.

But director-general Jim Groves says the circumstances are unusual.

“This is what we call a quota management fishery. These fishermen, some of them have actually paid to go and catch these fish so they’ve paid for a right they no longer have because of a natural disaster, so that’s what makes it different to past events,” he said.

I hadn’t actually got chance to look at the track of the cyclone yet, but after plotting the path above in Google Earth, it looks like the Swains Reefs in the south-eastern GBR took a direct hit whilst hamish was a category 5 (>290km/h wind gusts).

“Carbon emissions creating acidic oceans not seen since dinosaurs”

“The choice to continue emitting carbon dioxide means that we will be an agent of biological change of a force and magnitude exceeded only by the causes of the great mass extinction events. If we do not cut carbon dioxide emissions deeply and soon, the consequences of ocean acidification will stand out against the broad reaches of geologic time. Those consequences will remain embedded in the geologic record as testimony from a civilisation that had the wisdom to develop high technology, but did not develop the wisdom to use it wisely.” – Ken Caldiera (10.03.08)

The reef science corner

picture-388

Dr. John Bruno’s column “Reef Science Corner” on all things coral, climate, and conservation are coming to a close on The Reef Tank blog and we’re sad to see it go!  What originally started as merely an excerpt of a modified version of an article Dr. Bruno published last year on the Earth Portal and archived here in the Coral Reefs Collection of the Encyclopedia of Earth, which became a vast, educational tool to provide awareness of two very pertinent topics that TRT holds near and dear to its heart!

Moving from an introduction to corals on coral reefs and patterns of coral loss to climate change and all of it’s repercussions (which circles back to coral loss and also focuses on other marine conservation matters), Dr. Bruno (ironically, no pun intended) shifts from one course of action to the other, first speaking specifically about the history of corals, why they have formed where they are found to this day, and where prominent patterns of coral loss reside to the concerns raised by the world’s climate change, which are affecting these corals and also causing problems like patterns of coral loss and the threat that the world’s oceans are becoming more acidic—ocean acidification.

We learned about what could potentially happen in the future to our marine life, corals, and big, beautiful ocean if we don’t start becoming aware and doing something about these repercussions, and we learned why corals are so important to our world.  Finally, we will soon learn why we should continue to remain optimistic despite all of the troubles our marine existence is experiencing today.  That last and final post will be coming up next week.

We had an exceptional marine ecologist, conservation biologist, associate professor of Marine Science, and Climate Shifts blog (https://climateshifts.org) contributor on hand to provide us with all the information that goes into understanding and conserving the essence of marine communities and for that we are truly grateful! He has truly opened our eyes and we encourage you to read his work on The Reef Tank and continue to read his interesting, educated, and thought-provoking posts on Climate Shifts!
