First Coral IVF babies on the Reef have produced next generation

The first Coral IVF babies on the Great Barrier Reef have produced the next generation as part of this year’s mass coral spawning event, becoming the first time a breeding population has been established on the Great Barrier Reef using the innovative process.

Researchers have found 22 large coral colonies that were born through the first Coral IVF trial on the Reef in 2016 have survived a bleaching event, grown to maturity and were filled with eggs and sperm ready to spawn after the recent full moon. Many of the other smaller colonies are not quite large enough to reproduce but should be breeding next year.

Great Barrier Reef Foundation Managing Director Anna Marsden said, “We couldn’t be more excited to see that these coral babies have grown from microscopic larvae to the size of dinner plates, having not only survived a bleaching event but are now reproducing themselves – helping to produce larvae that can restore a degraded reef.

“Our Reef is an irreplaceable ecosystem that is home to many thousands of marine species, but it’s under threat from climate change. We need to reduce emissions as well as pioneer new solutions to help reefs recover and adapt to the warmer temperatures we’re already locked into,” Ms Marsden said.

“After seeing the potential of this game-changing technique the Great Barrier Reef Foundation and its partners brought Coral IVF to the Reef back in 2016 bringing together people and science to give nature a helping hand.

“Saving the Reef is a huge task, but having proof that this innovative, cutting-edge science works gives us hope.”

Lead Researcher and Southern Cross University Distinguished Professor Peter Harrison said, “Coral IVF is the first project of its kind to re-establish coral on damaged reefs by collecting millions of coral eggs and sperm during the spawning season, growing them into baby corals and releasing them directly onto degraded areas of the Reef.”

“The ultimate aim of this process is to produce new breeding populations of corals in areas of the Reef that no longer have enough live corals present due to being damaged by the effects of climate change,” Prof. Harrison said.

“This is a thrilling result to see these colonies we settled during the first small-scale pilot study on Heron Island grow over five years and become sexually reproductive.

“The larvae generated from these spawning corals have dispersed within the Heron Island lagoon and may settle on patches of reef nearby, helping to further restore other reef patches that have been impacted by climate change.

“This has given me and the rest of the team renewed enthusiasm as we research additional techniques on Lizard Island, through the Reef Restoration and Adaptation Program in collaboration with CSIRO, QUT and with support from Australian Institute of Marine Science, that will enable us to scale up and optimise this technique.”

The Reef Restoration and Adaptation Program is the world’s largest and most ambitious effort to develop, test and deploy at-scale protection, restoration and adaptation interventions to ensure that the Great Barrier Reef and coral reefs globally can resist, adapt to, and recover from the impacts of climate change.

The Program is funded by the partnership between the Great Barrier Reef Foundation and the Australian Government’s Reef Trust and is delivered by a collaboration between Australian Institute of Marine Science, the Great Barrier Reef Foundation, CSIRO, The University of Queensland, QUT, Southern Cross University and James Cook University.

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
