Breakthrough for the Reef

In a breakthrough for the reef probiotics proven to boost coral survival

In a scientific breakthrough for the Reef, researchers have proven that feeding coral a dose of good bacteria increases their overall health and tolerance to stresses related to climate change such as rising water temperatures.

Breakthrough for the Reef

Great Barrier Reef Foundation Managing Director Anna Marsden said pioneering science such as this provides hope for the future of the Great Barrier Reef that is already seeing the effects of climate change with our precious icon weathering its third mass bleaching in just five years.

“People may be surprised to find out that just like us, corals rely on a host of good bacteria to help keep them healthy and, just like us, the balance between good and bad bacteria is often disrupted in times of stress,” Ms Marsden said.

“Probiotics have been widely and successfully used to improve both human and animal health, however their use in marine ecosystems has been largely unexplored until now.

Breakthrough for the Reef

“It is fitting to announce this breakthrough for coral survival during World Ocean Week, a time when the world is reminded of the importance of oceans and its coral reefs as critical ecosystems that are essential to the future of our planet.

“Not only are coral reefs home to 25% of the ocean’s marine life but they also support the livelihoods of 1 billion people globally.

“However, we are increasingly seeing corals becoming stressed due to threats such as rising water temperatures which is causing them to become prone to infections and less likely to survive.

Breakthrough for the Reef

“Federal University of Rio de Janeiro Professor Raquel Peixoto and her international research collaborators, who include scientists from Brazil, US, UK, and James Cook University in Australia, have been able to prove for the first time, in a laboratory setting, that feeding corals beneficial probiotics increases their overall health and improves their chance of survival during heat stress.

“We fed the corals with beneficial microorganisms, which is like feeding them probiotic yoghurt full of good bacteria,” Prof. Peixoto said.

“Then we ran numerous stress tests on the corals, and time and time again the corals that had received the probiotics were in better health than those that had not.

Breakthrough for the Reef

“This finding is an exciting breakthrough in boosting the ability of coral species to survive in times of stress and help them cope with a changing climate.”

“This technology can be used by Queensland research institutions such as the Australian Institute of Marine Science to help boost the health of the corals reared in their National Sea Simulator before they are transported out to the Reef as part of their reef restoration projects,” Ms Marsden said.

“The survival rate of these corals once they are out on the Reef is currently quite low so giving them a health boost while they are in the Sea Simulator will boost their chance of survival.

Breakthrough for the Reef

“It will add another tool to Reef researchers’ toolkits as they commence the world’s most ambitious Reef restoration and adaptation effort (Reef Restoration and Adaptation Program).”

Professor Peixoto’s research team are currently running tests on different species of corals in the world’s largest artificial ocean (the Biosphere 2) in Arizona and in laboratories at the University of Hawaii to refine which groups of good bacteria are the best for each species.

They are also investigating new methods to scale up the application for use on coral reefs, such as delivering parcels of slow release probiotics to targeted reefs during times of heat stress.

Breakthrough for the Reef

This research project won the Great Barrier Reef Foundation’s Out of the Blue Box Reef Innovation Challenge People’s Choice Award supported by The Tiffany & Co. Foundation.

The Tiffany & Co. Foundation has supported ocean conservation efforts for two decades and are so pleased to see the Out of the Blue Box Reef Innovation Challenge from 2018 continue to kickstart and accelerate novel solutions from around the world to bolster the Great Barrier Reef’s long-term resilience, especially at a time when the Great Barrier Reef is being hit with the third major bleaching event in five years.

“Saving the Reef is a huge task and this pioneering research project is just one of the ways that we’re making a real difference with our partners,” Ms Marsden said.

Breakthrough for the Reef

“Using science, we’re gaining an understanding of the Reef with 3D mapping and DNA sequencing, partnering with groups like NASA, Google and the Australian Institute of Marine Science (AIMS) and pioneering new Australian technologies, like QUT’s Reef RangerBots and sun shield technology with Melbourne and Deakin Universities and AIMS, to monitor and protect corals.

“We are also restoring Reef islands to protect precious marine life, including the world’s largest green turtle nesting area and rebuilding reefs using coral IVF, as well as partnering with the Smithsonian to store cryogenically frozen coral samples so they’re never lost.”

Is This The Best Dive Center Ever? W\@wakatobidiveresort

@sennacher 
#askmark Hi there, regarding DSMBs. I’m no expert whatsoever and normally I deploy it correctly. This weekend we dove on very strong current and I almost lose my breath while deploying it (mouth inflate) as it tangled a bit on my reg. It scared the sh&t out of me so. Is there any “little cylinder” kind of thing in order to keep my reg in my mouth to deploy it safer?  I haven’t tried to do it with my LPI… but asume it would tangle also.
Thanks

Is There an Easier Way to Deploy a dSMB?

How Twinset Valves Work In Scuba Diving | Shutdown Drills And Isolator Tips Explained #scubadiving #askmark #twinset

Confused about how to use twinset valves or perform a proper valve shutdown drill? You’re not alone.

In this AskMark episode, Mark explains how valves work on twin cylinders, including how to safely open and close them, how isolator valves function, and why valve drills (also known as shutdown drills or V-Drills) are critical for diagnosing leaks during technical and recreational dives. Please visit our website for more Scuba news, underwater photography, hints & advice, and travel reports: https://divernet.com/ 

Mark also shares tips on muscle memory for reaching your left and right posts, isolator-first vs isolator-last logic, and how to prevent over-tightening or unsafe valve positioning. This guide is perfect for divers transitioning to twinsets, sidemount divers curious about manifold setups, or anyone wanting to improve their gas management skills. 

Let us know in the comments how your instructor taught valve drills and don’t forget to leave your questions using #AskMark to get featured in a future video.

How Do Valves Work on Twin Cylinders? #askmark
@mostafametwally1
#askmark hi Mark. Could you do a video on how to deal with the valves and manifold on twin cylinders. It’s confusing to remember which way to open the valves and it’s easy to get wrong particularly in emergencies. Thanks
