Australian scientists have discovered a massive detached coral reef in the Great Barrier Reef. It is the eighth detached reef discovered in the northern Great Barrier Reef and the first to be discovered in over 120 years.
<p>According to <a href="https://www.theguardian.com/environment/2020/oct/28/scientists-discover-500-metre-tall-skyscraper-reef-at-australias-great-barrier-reef" rel="noopener noreferrer" target="_blank">The Guardian</a>, detached reefs are not part of the main body of the Great Barrier Reef and instead spring from the ocean floor off the continental shelf. These types of reefs act like isolated seamounts because there is a lot of deep water between them and the next coral community, explained team lead Robin Beaman to The Guardian. This opens up the possibility of unique species evolving.</p>
<p>The reef was first spotted on Oct. 20 by scientists conducting underwater mapping of the seafloor off of a Schmidt Ocean Institute (SOI) research vessel, reported <a href="https://www.newsweek.com/great-barrier-reef-coral-empire-state-building-1542066" rel="noopener noreferrer" target="_blank">Newsweek</a>.</p><p>"This unexpected discovery affirms that we continue to find unknown structures and new species in our Ocean," Wendy Schmidt, SOI co-founder, said in a <a href="https://schmidtocean.org/australian-scientists-discover-500-meter-tall-coral-reef-in-the-great-barrier-reef-first-to-be-discovered-in-over-120-years/" target="_blank">statement</a>.</p><p>The team 3-D mapped the reef in detail and used an underwater robot named SuBastian to explore the reef and <a href="https://www.youtube.com/watch?v=L_Ee7JV5oSI&feature=youtu.be" target="_blank">live-stream video</a>.</p>

<p>While the newly discovered reef does not appear to have a lot of hard corals in the shallowest section, SuBastian observed "an incredible abundance" of sponges, sea fans and soft corals in addition to reef fish and grey reef sharks, reported The Guardian. This rich <a href="http://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> suggests that the area is rich in nutrients that are carried from deep waters by strong currents and upwellings, the news report said.</p><p>"We are surprised and elated by what we have found," Beaman said in the SOI statement. "To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible."</p>
<p>Scientists estimated the reef to be 20 million years old at its deepest point, reported <a href="https://www.abc.net.au/news/science/2020-10-27/reef-detached-discovered-cape-york/12816760" rel="noopener noreferrer" target="_blank">ABC News</a>. The base of the reef is almost 5,000 feet wide, and it rises 1,600 feet tall — dwarfing iconic skyscrapers like the Empire State Building in New York City and the Petronas Twin Towers in Kuala Lumpur, <a href="https://www.nbcnews.com/science/environment/coral-reef-taller-empire-state-building-discovered-australia-s-great-n1244955" rel="noopener noreferrer" target="_blank">NBC</a> reported. At its shallowest, the peak is just 130 feet below the ocean's surface.</p><p>"To find a new half-a-kilometer tall reef in the offshore Cape York area of the well-recognized Great Barrier Reef shows how mysterious the world is just beyond our coastline," said Jyotika Virmani, SOI executive director, in the SOI statement. "This powerful combination of mapping data and underwater imagery will be used to understand this new reef and its role within the incredible Great Barrier Reef World Heritage Area."</p>
<p>According to Newsweek, the Great Barrier Reef is the largest living structure in the world. It comprises nearly 133,000 square miles which include 3,000 coral reefs, 600 continental islands and 150 mangrove islands.</p><p>Despite its massive size, the reef is <a href="https://www.ecowatch.com/great-barrier-reef-bleaching-2645210028.html" target="_self">under severe threat</a>. The <a href="https://www.ecowatch.com/australia-great-barrier-reef-poor-2640118306.html" target="_self">outlook is "very poor</a>" because the climate crisis has raised ocean temperatures, which can stress corals and cause them to "bleach" or expel symbiotic algae, leaving white coral skeletons exposed. While not deadly, <a href="https://www.ecowatch.com/tag/coral-bleaching" target="_self">coral bleaching</a> leaves the animal vulnerable, and prolonged or repeated bleaching events have been known to kill coral reefs, reported Newsweek. Recently, another team of scientists estimated that the Great Barrier Reef has already <a href="https://www.ecowatch.com/great-barrier-reef-corals-climate-crisis-2648203228.html" target="_self">lost half of its corals to the climate crisis</a>.</p><p>Co-author of that study, Terry Hughes of James Cook University urged, "We still have an opportunity to save the reef if we deal with climate change. 1.1 degrees of warming so far has triggered five bleaching events since 1998 [but] we still have half a reef," reported ABC News.</p><p>The scientists will continue to map the area until mid-November. Earlier discoveries on this same research cruise included what is believed to be the <a href="https://www.ecowatch.com/worlds-longest-animal-ocean-2645712197.html" target="_self">longest recorded sea creature</a>, a siphonophore potentially longer than 390 feet. The new reef and the other findings will likely lead to years of study, The Guardian reported.</p><p>"This is evidence for the importance of exploring our undersea environment so that we can protect it," SOI spokesperson Carlie Wiener told ABC News.</p>

Amazing Drone Footage Captures Thousands of Turtles Migrating Near Great Barrier Reef
12 June 2020
Animals
Australian researchers captured a stunning scene that looks like something out of Finding Nemo. The drone the scientists used recorded approximately 64,000 green turtles migrating near Australia's Great Barrier Reef for nesting season, as CNN reported.
<p>The footage from the Queensland Government's Department of Environment and Science (DES) spotted the turtles congregating at the world's largest green turtle rookery at Raine Island, a vegetated coral cay approximately 385 miles northwest of Cairns in Queensland, according to <a href="https://www.cnn.com/2020/06/09/world/green-turtle-drone-nesting-intl-scli-scn/index.html" target="_blank">CNN</a>.</p><p>The sheer number of turtles surprised the scientists who realized they had underestimated the number of green turtles in the area by 50 percent, according to <a href="https://www.youtube.com/watch?v=YAVk4jvWzDw" target="_blank">Voice of America's YouTube</a> post showing the footage.</p>
<p>"We were underestimating that a lot. We're finding 1.73 times as many turtles with the drone ... when we directly compare with the observer counts," Dr. Andrew Dunstan, from the DES, told <a href="https://www.cnn.com/2020/06/09/world/green-turtle-drone-nesting-intl-scli-scn/index.html" target="_blank">CNN</a> Tuesday, adding that the team can now go back and adjust historic population estimates.</p><p>Prior to using drones, researchers would count turtles as they landed on the beach to lay eggs. They would then mark the turtles with a non-toxic paint to track them in the ocean. However, accurately counting thousands of painted and unpainted turtles from a boat in the water proved difficult and unreliable, according to the <a href="https://www.youtube.com/watch?v=YAVk4jvWzDw" target="_blank">Voice of America</a> post.</p>
<p>Using a drone is easier, safer, much more accurate, and the data can be immediately and permanently stored," Dunstan, senior research scientist and lead author of a paper about the turtles published in PLOS ONE on Thursday, said in a <a href="https://www.des.qld.gov.au/our-department/news-media/mediareleases/drone-technology-helps-count-turtles-gbr" target="_blank">statement</a>, as <a href="https://www.cnn.com/2020/06/09/world/green-turtle-drone-nesting-intl-scli-scn/index.html" target="_blank">CNN</a> reported.</p><p>"What previously took a number of researchers a long time can now be by one drone operator in under an hour," said researcher Richard Fitzpatrick from the Biopixel Oceans Foundation, as <a href="https://www.prevention.com/life/a32839141/sea-turtles-australia-raine-island-drone-video/" target="_blank">Prevention</a> reported.</p><p>Green sea turtles are a <a href="https://environment.des.qld.gov.au/wildlife/threatened-species/vulnerable/green-turtle" target="_blank">vulnerable species</a> in Queensland since they are hunted for their flesh and eggs, are often trapped in trawler fishing nets, and choke on discarded plastic bags, according to the <a href="https://www.smh.com.au/environment/sustainability/drone-footage-shows-twice-the-number-of-green-turtles-at-rookery-than-previously-thought-20200610-p5516p.html" target="_blank">Sydney Morning Herald</a>. Eleven species of green turtles <a href="https://www.fisheries.noaa.gov/species/green-turtle#:~:text=Green%20turtles%20are%20protected%20under,significant%20portion%20of%20its%20range." target="_blank">are listed as either endangered or threatened</a> in the Endangered Species Act in the U.S.</p>
<p>"We sort of became aware that although there's these massive aggregations, the actual reproduction isn't working so well," said Dunstan to <a href="https://www.cnn.com/2020/06/09/world/green-turtle-drone-nesting-intl-scli-scn/index.html" target="_blank">CNN</a>, explaining that his team noticed turtles were falling off cliffs, becoming trapped in the heat and suffering flooding in their nests.</p><p>In their <a href="https://www.des.qld.gov.au/our-department/news-media/mediareleases/drone-technology-helps-count-turtles-gbr" target="_blank">statement</a>, as <a href="https://www.prevention.com/life/a32839141/sea-turtles-australia-raine-island-drone-video/" target="_blank">Prevention</a> noted, the DES said they're "taking action to improve and rebuild the island's nesting beaches and building fences to prevent turtle deaths, all working to strengthen the island's resilience and ensure the survival of our northern green turtles and many other species."</p>

More and more Americans are retrofitting their bathrooms with high-end bidets, allowing them to enjoy cleanliness and hygiene without creating as much paper waste. Not all bidets are created equal, however, and before deciding on a particular brand, it's important to do your homework. Take a look at our comprehensive Toto bidet review, and our reviews of Tushy and Omigo, to learn more about all of their options.
<h2>Toto overview</h2><p>Toto is a company that has been around for over 100 years. They aim to improve people's quality of life, and they do that specifically by focusing on bathrooms. To that end, Toto is known for high-quality products including toilets, faucets, showers, bathtubs, and bidets. </p><p>Toto has also expressed an admirable commitment to ecological stewardship. As <a href="https://www.totousa.com/about-toto/toto-way" target="_blank">their corporate website</a> notes, they strive to "protect the global environment by conserving finite natural resources and energy." One example of this is their donation of any imperfectly fired porcelain products for recycling and reuse as porcelain floor tile. Their <a href="https://www.totousa.com/about-toto/living-toto-library/smart-sustainable-packaging-solution" rel="noopener noreferrer" target="_blank">packaging</a> uses differing levels of recycled post-consumer paper products while their forklifts operate using <a href="https://www.totousa.com/about-toto/living-toto-library/plant-based-hydraulics" rel="noopener noreferrer" target="_blank">plant-based hydraulics</a> made from soybean oil instead of traditional hydraulic oil.</p><p>Toto is definitely a company with a superior reputation when it comes to bathroom accessories in general, and bidets in particular. Here are reviews of some of the specific products in the Toto line.</p><h2>Toto bidet reviews</h2><p>There are two different bidet product families available from Toto: standalone bidets and bidet seat attachments. Their standalone models include the Piedmont bidet, the Lloyd bidet, and the Clayton bidet, while their bidet toilet seat offerings include a wide selection in the popular Washlet line. Here are details on the three standalone options and three of the most popular bidet seat attachments.</p><p><em>Each product featured here has been independently selected by the writer. If you make a purchase using the links included, we may earn commission.</em></p><h3>Toto standalone bidets</h3><h4></h4>
<h2>Toto bidet pros and cons<br></h2><p>Whether you're considering a standalone bidet or a bidet seat attachment, here are some of the pros and cons to help you compare your options.</p><h3>Pros</h3><ul class="ee-ul"><li>Standalone bidets, such as the ones offered by Toto, are designed in a wider range of elegant, contemporary styles. If you are looking to remodel your bathroom, splurging for a standalone bidet makes sense.</li><li>Toto offers a wide selection of bidet and bidet attachment options. Some of their more advanced units feature night lights, adjustable nozzle positions, warm air dryers, and adjustable settings for the temperature of the water.</li><li>All of the Toto bidet attachments we reviewed include self-cleaning nozzles for added hygiene. They are also designed for DIY installation, and easily connect to your existing toilet's water supply without the need for a plumber or electrician.</li></ul><h3>Cons</h3><ul class="ee-ul"><li>Toto's line of standalone bidets and bidet seat attachments are more expensive than some other brands, especially some of their more high-end models.</li><li>Standalone bidets may not be as convenient for those who have mobility issues.</li><li>All of Toto's bidet seat attachments are electric, and don't feature an eco or energy-saving mode like some other options.</li></ul><h2>The benefits of buying a bidet</h2><p>Why buy a bidet at all? There are plenty of perks, both for you and the planet:</p><ul class="ee-ul"><li>Bidets offer a more thorough, hygienic cleaning than toilet paper.</li><li>They're considerably more eco-friendly, using less water and paper.</li><li>Because you'll use so much less toilet paper, bidets are also more cost-effective.</li><li>Compared with TP, bidets can be really soothing to the skin.</li><li>They have special benefits for women, and especially pregnant women, helping minimize the risk of a UTI.</li><li>Bidets are highly accessible, even to those with limited mobility.</li><li>A bidet makes it much easier to teach your children about proper bathroom hygiene.</li></ul><h2>Considerations when buying a bidet</h2><p>As you consider all of your options for getting a bidet, here are a few of the key factors to consider:</p><ul class="ee-ul"><li>Look for a bidet with a self-cleaning nozzle. This will help keep things hygienic.</li><li>Electric vs. non-electric? Electric bidets can offer more comfort features, like a heated seat, but they also use more energy than a non-electric one.</li><li>Is it a standalone bidet, a bidet seat, or a bidet attachment? While a standalone bidet is a completely separate fixture from your toilet, a bidet seat will completely replace your existing seat and a bidet attachment will be installed onto your existing toilet seat. These are usually the least expensive, but also come with the fewest features.</li><li>Does the bidet connect to your home's hot water? If it doesn't, you will only be able to clean with cold water.</li><li>Make sure you can adjust the settings. For the most comfortable bidet, look for controls that let you customize the water pressure, the angle of the water stream, the temperature of the water, and the temperature of the seat, if it is heated.</li></ul><p>Use these questions to determine whether the bidets from Toto are right for you.</p><h2>Toto bidets: a leader in comfort and efficiency</h2><p>Toto makes durable, elegant, and highly functional products that will allow you to enjoy all the hygienic and environmental benefits of a bidet. You can also read our full review of the best bidets to compare with other brands like Brondell, Kohler, Tushy, and BioBidet.</p><p><em><strong>Josh Hurst </strong></em><em>is a journalist, critic, and essayist.

As restoration managers repair damaged corals, sound recordings can help jumpstart the process of restoring vibrant – and noisy – coral reef ecosystems. CC by 2.0
A healthy coral reef is a noisy place.

<p>"You've got this constant crackling sound. … That's the sound of snapping shrimp," says Steve Simpson of the University of Exeter in the United Kingdom. "Then on top of that, pops, grunts, growls, trumpeting sounds, whooping sounds … and these are generally made by fish that are communicating with each other."</p><p>But Simpson says after damaging coral bleaching events – which are growing more common as oceans warm – that soundscape changes.</p><p>He says that when his team visited part of the Great Barrier Reef after a major bleaching event, "really to our shock, we found that the reef had gone quiet."</p>
<p>It was a sign that many sea creatures had left the area. Now Simpson's team is using sound to draw some of that life back.</p><p>At 11 locations in the Great Barrier Reef, they played recordings of a healthy reef ecosystem. After six weeks, they compared the fish life in those places with that in other areas. They found that twice as many fish had returned to the audio-enriched sites.</p><p>So Simpson says that as restoration managers repair damaged corals, sound recordings can help jumpstart the process of restoring vibrant – and noisy – coral reef ecosystems.</p>

Australia Throws Great Barrier Reef a $300 Million Lifeline, but Will It Cut Emissions?
20 April 2020
Science
Australia's Reef Restoration and Adaptation Program will further investigate 43 potential fixes for the Great Barrier Reef in a wide-scale rescue effort. Australian Institute of Marine Science
The Great Barrier Reef is in trouble. The Australian government is trying to buy its crown jewel some time, but is it willing to support what the reef needs most — a reduction in emissions?
<p>A few weeks ago, the world's greatest coral reef suffered its <a href="https://www.ecowatch.com/coral-bleaching-great-barrier-reef-2645576557.html" target="_self">third major bleaching event</a> in five years, the <a href="https://www.ecowatch.com/great-barrier-reef-bleaching-2020-2645655957.html" target="_self">most widespread to date</a>. The frequency and severity of the bleachings have caused some scientists to speculate whether the reef has reached a <a href="https://www.ecowatch.com/coral-reef-bleaching-frequency-2645625927.html" target="_self">tipping point</a> of no return.</p><p>On Thursday, Minister of the Environment Susan Ley announced the launch of the <a href="https://www.gbrrestoration.org/rrap-r-d-program" target="_blank">research and development (R&D) phase</a> of the government's <a href="https://www.gbrrestoration.org/home" target="_blank">Reef Restoration and Adaptation Program (RRAP)</a> to combat the declines the reef is experiencing.</p>
<p>Following a <a href="https://www.gbrrestoration.org/investment-case-reports" target="_blank">two-year feasibility study</a> led by the <a href="https://www.aims.gov.au/" target="_blank">Australian Institute of Marine Science (AIMS)</a>, a list of 160 potential fixes was whittled down to 43 promising concepts that will be funded for further investigation.</p><p>AIMS Chief Executive Paul Hardisty described how the R&D phase will "provide the scientific basis to help the reef survive in the coming decades," noted a <a href="https://app.wipster.io/Review/CYd0JQB8xsdI6pVHEelJXg9d9n6MKF2hFwrJS8xnAHVqhhilgA#asset=1" target="_blank">media statement</a>. The program is designed to uncover adaptations for the reef that are cost-effective, safe, and acceptable to the public and regulators, Hardisty said.</p><p>But how effective can an adaptation and resilience program really be against the backdrop of ever-increasing global emissions and ocean temperatures?</p>

The Great Barrier Reef is the world's largest coral reef ecosystem. Stretching 2,300 km along Australia's northeast coastline, this complex of shallow water reefs and islands is home to thousands of species of fish, invertebrates, algae, reptiles, birds and algae. This image, taken by the VIIRS sensor on the Suomi NPP satellite on Aug.19, 2017 uses the high resolution SVI 3, 2, and 1 bands, commonly referred to as "natural color" RGB. NOAA National Environmental Satellite, Data, and Information Service (NESDIS)
<p>The feasibility study found that global warming might kill the entire Great Barrier Reef by as early as 2050, reported Hack.</p><p>Most tropical coral reefs will disappear even if <a href="https://www.ecowatch.com/climate-change-ipcc-report-2610866229.html" target="_self">heating can be limited to 1.5°C</a>, the UN's Intergovernmental Panel on Climate Change <a href="https://www.ipcc.ch/sr15/chapter/chapter-3/" target="_blank">said</a>, reported <a href="https://www.theguardian.com/environment/2020/apr/16/brightening-clouds-and-coral-larvae-study-picks-best-great-barrier-reef-rescue-ideas" target="_blank">The Guardian</a>. Reefs will still be "at very high risk" at 1.2°C warming, and the globe is already over 1°C since the Industrial Revolution, The Guardian explained.</p><p>The feasibility report concluded, "We are facing the very real prospect that, within a generation and without concerted action to reduce emissions and help drive adaptation and faster recovery from damage, the Great Barrier Reef as we have known it will cease to exist," reported <a href="https://www.abc.net.au/triplej/programs/hack/australias-daring-attempt-to-save-great-barrier-reef-has-begun/12155326" target="_blank">Hack</a>.</p><p>To avoid this, the scientists are calling for an intervention at a scale never seen before, and they're trying to find adaptation solutions before climate change destroys what remains of the reef, <a href="https://www.theguardian.com/environment/2020/apr/18/rebuild-it-shade-it-breed-it-three-tactics-to-buy-time-for-the-great-barrier-reef" target="_blank">The Guardian</a> reported.</p>

<p>Daniel Harrison, a biological oceanographer at Southern Cross University, led one of the 43 experimental trials being funded for further research.</p><p>"This is a race against time," he said to The Guardian. "If we can go really hard on emissions and meet or beat the Paris [climate] targets, then these interventions have the potential to help get the reef to a sustainable future – but only under that very aggressive emissions reduction scenario."</p><p>Therein lies one of the historically sticky points for environmentalists when it comes to Australia's "hypocritical" environmental protection efforts contrasted against its broader, coal-friendly environmental policies, reported <a href="https://fortune.com/2018/04/30/australia-great-barrier-reef-climate-change/" target="_blank">Fortune</a>.</p><p>In 2017, <a href="https://www.greenpeace.org.au/news/governments-coal-crush-real-threat-great-barrier-reef/" target="_blank">Greenpeace</a> called the government's "coal crush" the real threat to the Great Barrier Reef because it "[ignored] the simple reality of climate change." In 2018, Australia invested $379 million into saving the reef. The government <a href="https://www.ecowatch.com/usda-removing-safeguards-on-food-2645756313.html" target="_self">concurrently promoted the building of new coal mines</a>, which fuel global warming that harms the reef.</p><p>In 2019, Australia continued its "love affair with fossil fuels," setting <a href="https://www.ecowatch.com/australia-emissions-record-high-2639152810.html?rebelltitem=1#rebelltitem1" target="_self">new record highs for emissions pollution</a>. That same year, the marine park authority approved plans to dump one million tonnes (approximately 1.1 million U.S. tons) of sludge onto the reef.</p><p>As recently as December 2019, coal advocate and current Prime Minister Scott Morrison received backlash for vacationing in Hawaii and seeming "<a href="https://www.ecowatch.com/australia-fires-michael-mann-2644442561.html" target="_self">remarkably indifferent</a>" while bush fires devastated the country, reported <a href="https://www.washingtonpost.com/climate-environment/as-fires-devastate-australia-a-coal-loving-leader-faces-an-early-test/2020/01/08/a7827ebc-3178-11ea-91fd-82d4e04a3fac_story.html" target="_blank">The Washington Post</a>. The fires were exacerbated by climate change and the spike in greenhouse gases caused by the burning of fossil fuels, explained The Washington Post.</p><p>In response, Morrison said, "Our emissions reductions policies will both protect our environment and seek to reduce the risks and hazards we are seeing today," reported The Washington Post.</p>
<p>The realities of climate change and coral bleaching have led even the scientists spearheading this latest effort to save the reef to characterize the RRAP as a long shot, reported <a href="https://www.abc.net.au/triplej/programs/hack/australias-daring-attempt-to-save-great-barrier-reef-has-begun/12155326" target="_blank">Hack</a>.<br></p><p>AIMS principal research scientist Ken Anthony told <a href="https://www.theguardian.com/environment/2020/apr/18/rebuild-it-shade-it-breed-it-three-tactics-to-buy-time-for-the-great-barrier-reef" target="_blank">The Guardian</a>, "It's a bit like the Apollo 11 mission. It really is on that scale."</p><p>Hardisty also metaphorically compared the new program to the "high-risk but successful U.S. mission to put a man on the moon before the end of the '60s," reported <a href="https://www.abc.net.au/triplej/programs/hack/australias-daring-attempt-to-save-great-barrier-reef-has-begun/12155326" target="_blank">Hack</a>. He agreed that success might seem like a "moonshot," given the current situation on the reef and global emissions, but optimistically added, "If we work hard and are smart and are courageous we can turn this around," reported Hack.</p><p>The R&D phase will be funded by the Australian government and a consortium of universities and marine studies institutes. The government committed $150 million for the next five years, and that figure could jump to $300 million with promised donations from the private sector and in-kind investments from R&D providers, noted a <a href="https://minister.awe.gov.au/ley/media-releases/150-million-drive-innovations-boost-reef-resilience" target="_blank">government press release</a>.</p><p>The feasibility study found that the efforts could result in a net benefit to Australia of tens of billions of dollars, much greater than the initial investment, the <a href="https://www.gbrrestoration.org/investment-case-reports" target="_blank">investment case</a> said.</p>

The Great Barrier Reef's third mass bleaching event in five years is also its most widespread, according to new data released Tuesday.
<p>Professor Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University, spent nine days in a plane surveying 1,036 reefs from the air, <a href="https://www.theguardian.com/environment/2020/apr/07/great-barrier-reefs-third-mass-bleaching-in-five-years-the-most-widespread-ever?CMP=twt_a-environment_b-gdneco&fbclid=IwAR1-d44F2zLeqzTlILpNyrT7E7TWHMxYd5eMYvFOGnHaVFwx-tN1EQyQf2Q" target="_blank">The Guardian reported</a>. He found that 25 percent of the overall reef was severely bleached. What's more, he observed bleaching in the north, center and south of the reef for the first time.</p><p>"It's the first time we've seen severely bleached reefs along the whole length of the reef, in particular, the coastal reefs," Hughes told <a href="https://www.nytimes.com/2020/04/06/world/australia/great-barrier-reefs-bleaching-dying.html?campaign_id=51&emc=edit_MBE_p_20200407&instance_id=17430&nl=morning-briefing&regi_id=88631294&section=whatElse&segment_id=24116&te=1&user_id=d8eb7cee9d3c5ab39515239b6ec54d19" target="_blank">The New York Times</a>.</p>

<p>The Great Barrier Reef has <a href="https://www.aims.gov.au/docs/research/climate-change/coral-bleaching/bleaching-events.html" target="_blank">suffered six mass bleaching events</a> due to warmer than normal ocean temperatures: in 1998, 2002, 2006, 2016, 2017 and now 2020. While the 1998 and 2016 bleachings occurred during El Niño events, a natural climate variation that brings warmer than average ocean temperatures to the region, the 2002 and 2017 events did not, The Washington Post pointed out. Neither did this year's, but it is the second most intense after 2016's. This suggests warmer temperatures caused by the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a> are ultimately driving these events.</p><p>"It's now clear that we can have major bleaching events caused by global climate change alone with no tropical forcing," Mark Eakin, coordinator for the National Oceanic and Atmospheric Administration's Coral Reef Watch program, told The Washington Post.</p><p><a href="https://www.ecowatch.com/tag/coral-bleaching" target="_self">Coral bleaching</a> occurs when heat stress causes corals to expel the algae that live within them, providing them both with food and their bright colors. When the algae leave, the corals lose those colors. If the algae stay away for too long, the corals can die.</p>
<p>2016 and 2017's bleachings together killed around half of the corals in the reef. But Hughes told <a href="https://www.abc.net.au/news/2020-04-07/great-barrier-reef-most-widespread-coral-bleaching-on-record/12107054" target="_blank">Australia's ABC News</a> that he didn't know how deadly this year's bleaching would be. He told The Guardian that the north and central portions of the reef would probably see less death because the less heat-resistant corals had already died off in 2016 and 2017.</p><p>But the south, which remained relatively untouched in previous years, was a different story.</p><p>"They hadn't bleached before, which means there are more corals and more of the corals that are particularly susceptible to heat stress," he told ABC News.</p>
<div id="4320a" class="rm-shortcode" data-rm-shortcode-id="a0e8364a0be8b2cb46e3c4770be57cb7"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1247367294029672448" data-partner="rebelmouse"><div style="margin:1em 0">I'm not sure I have the fortitude to do this again.

<p>This means the makeup of the reef is changing, but some of the losing corals include branching corals, which provide important habitat for many fish.</p><p>"Branching corals make all of the nooks and crannies that the rest of the biodiversity — the fish and so on — depend on," he told ABC News. "So having fewer and fewer corals is having a much broader effect, not just on the corals themselves, but in the broader ecosystem."</p><p>Hughes told The Guardian that only urgent climate action could save the reef.</p><p>"It's not too late to turn this around with rapid action on emissions," he said. "But business-as-usual emissions will make the Great Barrier Reef a pretty miserable place compared to today."</p>

Coral Reef Tipping Point: ‘Near-Annual’ Bleaching May Occur Globally, Scientists Say
03 April 2020

Tropical coral reefs are at a critical tipping point, and we've pushed them there, scientists say. Climate change may now cause previously rare, devastating coral bleaching events to occur in tropical coral reefs around the globe on a 'near-annual' basis, reported The Guardian.
<p>In February 2020, record-high sea temperatures at <a href="https://www.ecowatch.com/tag/great-barrier-reef" target="_self">Australia's Great Barrier Reef</a> caused the most widespread coral bleaching event at the reef ever, reported <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a>. Unfortunately, this was also the <a href="https://www.ecowatch.com/coral-bleaching-great-barrier-reef-2645576557.html" target="_self">third such major bleaching in five years</a>, raising concerns over the fragile corals' ability to keep rebounding against worsening marine conditions.</p><p>To put it into perspective, there have only ever been five recorded bleaching events at the <a href="http://www.ecowatch.com/tag/great-barrier-reef" target="_self">Great Barrier Reef</a>, explained Terry Hughes, director of the <a href="https://www.coralcoe.org.au/" target="_blank">Australian Research Council's Centre of Excellence for Coral Reef Studies</a> at James Cook University in North Queensland, to NBC News. The first two were in 1998 and 2002, and then there was a 14-year gap before the 2016 and 2017 events. The latter two resulted in the death of almost half of the famed reef's corals in just two years, NBC News reported.</p>
<p>Scientists weren't expecting another bleaching event so soon, explained Mark Eakin, coordinator of the National Oceanic and Atmospheric Administration's <a href="https://coralreefwatch.noaa.gov/satellite/index.php" target="_blank">Coral Reef Watch</a> program in College Park, Maryland to NBC News. "This has never happened before. We're in completely uncharted territory."</p><p>Now, Eakin warns that the accelerating frequency may indicate something far worse. "The real concern is with this much bleaching without tropical forcing," Eakin told <a href="https://www.theguardian.com/environment/2020/apr/01/climate-crisis-may-have-pushed-worlds-tropical-coral-reefs-to-tipping-point-of-near-annual-bleaching" target="_blank">The Guardian</a>. "This may be a sign we've now tipped over to near-annual bleaching in many locations."</p>
<p>Historically, tropical coral reefs bleach more often when the Pacific Ocean is in a phase known as El Niño, reported The Guardian. This latest bleaching on the reef has hit during a neutral phase in the cycle.</p><p>Eakin told The Guardian, "It's quite concerning that we are getting this much heat stress across the Great Barrier Reef in an Enso [El Niño southern oscillation]-neutral year."</p><p>Eakin's agency, Coral Reef Watch, monitors coral reefs across the globe, not just in Australia. Their research led Eakin to additionally conclude that there was a risk that this mass bleaching at the Great Barrier Reef could mark the start of another global-scale event, reported The Guardian.</p><p>"If we get another El Niño, the odds are almost 100% that we will see another global bleaching event," Eakin told The Guardian.</p><p>"The gap between one event and the next is shrinking, not just for the Great Barrier Reef, but reefs throughout the tropics," Hughes told <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a>. "That's important, because it takes a decade or so for a half-decent recovery of even the fastest-growing corals. The slowest ones take several decades."</p>
<p>Given their long recovery time, Eakin warned <a href="https://www.theguardian.com/environment/2020/apr/01/climate-crisis-may-have-pushed-worlds-tropical-coral-reefs-to-tipping-point-of-near-annual-bleaching" target="_blank">The Guardian</a>, "We are seeing these events far too frequently" for reefs to recover from mass mortality of corals due to bleaching.</p><p>The news report explained that corals bleach when they sit in abnormally hot water for too long. While corals can recover from mild bleaching, severe and prolonged heat stress can kill corals.</p><p>Eakin added, "What we are seeing on the Great Barrier Reef and potentially elsewhere is really being driven just by anthropogenic climate change," reported The Guardian.</p>
<p>Increased greenhouse gases in the atmosphere cause the planet to warm, and 90 percent of that extra heat is taken up by <a href="http://www.ecowatch.com/tag/oceans" target="_self">oceans</a>, explains the news report. According to <a href="https://www.cbsnews.com/news/climate-change-coral-reef-habitat/" target="_blank">CBS News</a>, because corals are extremely sensitive to ocean temperatures, <a href="https://www.ecowatch.com/coral-reefs-climate-crisis-predictions-2645201373.html" target="_self">raising the water temperature by even a couple of degrees can still result in mass coral bleaching</a>. And while bleaching does not kill the coral, it weakens them, making them vulnerable to disease, <a href="https://www.theguardian.com/environment/2020/apr/01/climate-crisis-may-have-pushed-worlds-tropical-coral-reefs-to-tipping-point-of-near-annual-bleaching" target="_blank">The Guardian</a> explained.</p><p>Eakin concluded, "There's so much heat that has been absorbed in the upper ocean that all the coral reefs are much closer now to their bleaching threshold. As result, it's very easy to tip them over," reported The Guardian.</p>

The Great Barrier Reef, a natural wonder that once teemed with life, just experienced a major coral bleaching event, according to scientists who conducted aerial surveys over hundreds of individual reefs, as The Guardian reported.
<p>According to <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a>, the entire Great Barrier Reef is suffering a period of unprecedented heat stress. This bleaching event is the third one in five years and questions remain about the corals' ability to recover from the constant onslaught from changing marine conditions. </p>
<p>"This has never happened before," Mark Eakin, coordinator of the National Oceanic and Atmospheric Administration's Coral Reef Watch program in College Park, Maryland, said as the <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News reported</a>.

<p>Bleachings don't necessarily kill the corals, but it does leave them extremely vulnerable to disease from bacteria or viruses. Bleaching, which occurs in response to abnormal conditions like heat or increased acidity in the water, forces the corals to release the tiny photosynthetic algae that live in their tissue and are responsible for their color, according to NBC News.</p>
<p>The previous two heat stress related bleaching events were in 2016 and 2017. Scientists say the frequency of the heat-induced bleaching is a direct result of the climate crisis, which spells trouble for the vitality of the reef since the corals do not have enough time to recover and to grow back, according to NBC News. </p>
<p>The scientists conducting the aerial surveys are from the <a href="https://www.coralcoe.org.au/for-managers/coral-bleaching-and-the-great-barrier-reef" target="_blank">ARC Centre of Excellence for Coral Reef Studies at James Cook University</a> in Queensland, Australia. </p>
<p>Terry Hughes, who runs the center, told <a href="https://www.theguardian.com/environment/2020/mar/25/great-barrier-reef-suffers-third-mass-coral-bleaching-event-in-five-years" target="_blank">The Guardian</a>, that after three days of the planned nine-day survey, "We know this is a mass bleaching event and it's a severe one. We know enough now that [the bleaching] is more severe than in 1998 and 2002. How it sits with 2016 and 2017 we are not sure yet."</p>
<p>Global warming is an enormous threat to the future of coral reefs around the world. As The Guardian reported, The UN's Intergovernmental Panel on Climate Change concluded from published evidence that a majority of tropical coral reefs would disappear even if heating was limited to the Paris agreement's target of 1.5 degrees Celsius and would be "at very high risk" at 1.2 degrees Celsius.</p>
<p>Hughes told <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a> there have been only five recorded Great Barrier Reef bleaching events. The first was in 1998, followed by 2002, then in 2016, 2017 and this year, setting up a disturbing pattern. </p>
<p>"The gap between one event and the next is shrinking, not just for the Great Barrier Reef, but forreefs throughout the tropics," Hughes said to <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a>. "That's important, because it takes a decade or so for a half-decent recovery of even the fastest-growing corals. The slowest ones take several decades."</p>
<p>While past bleaching events, like the ones in 2002 and 2016, were driven by El Niño weather events, this one happened just because the Australian summer was too hot. </p>
<p>"We no longer need an El Niño to trigger a bleaching event — we just need a hot summer," Eakin said to <a href="https://www.nbcnews.com/science/environment/great-barrier-reef-hit-third-major-bleaching-event-five-years-n1166676" target="_blank">NBC News</a>. "And the summers are getting hotter and hotter because of global warming. That is astounding in itself."</p>

Coral Reefs Could Be Completely Lost to the Climate Crisis by 2100, New Study Finds
20 February 2020
Climate

Researchers released a sobering study this week showing that all of the world's coral reefs may be lost to the climate crisis by 2100.
<p>The bleak outlook means that restoration efforts will face Herculean challenges, according to the research presented by researchers at this week's <a href="https://www.agu.org/Ocean-Sciences-Meeting/" target="_blank">Ocean Sciences Meeting 2020</a> in San Diego, California.</p><p>Rising sea temperatures, acidic water and pollution are proving too much for the reefs to handle. About 70 to 90 percent of the world's existing coral reefs are predicted to disappear in the next two decades, according to scientists from the University of Hawaii Manoa, as <a href="https://www.cnn.com/2020/02/20/world/coral-reefs-2100-intl-hnk-scli-scn/index.html" target="_blank">CNN</a> reported.</p><p>"By 2100, it's looking quite grim," said Renee Setter, a biogeographer at the University of Hawaii Manoa in a <a href="https://news.agu.org/press-release/warming-acidic-oceans-may-nearly-eliminate-coral-reef-habitats-by-2100/" target="_blank">statement</a>.</p><p>While pollution poses a large threat to many <a href="http://www.ecowatch.com/tag/oceans" target="_self">ocean</a> creatures, corals seem most at risk from emissions, according to the researchers.</p>
<p>"Trying to clean up the beaches is great and trying to combat pollution is fantastic. We need to continue those efforts," Setter said in a <a href="https://news.agu.org/press-release/warming-acidic-oceans-may-nearly-eliminate-coral-reef-habitats-by-2100/" target="_blank">statement</a>. "But at the end of the day, fighting climate change is really what we need to be advocating for in order to protect corals and avoid compounded stressors."</p><p>To make their predictions, the scientists mimicked future ocean conditions like sea surface temperature, wave energy, acidity, pollution and <a href="http://www.ecowatch.com/tag/overfishing" target="_self">overfishing</a> in areas where corals are today. Looking at those models, the scientists found that most parts of the ocean will not sustain habitats for corals by 2045, and almost no suitable habitats will exist by 2100, according to <a href="https://www.cbsnews.com/news/climate-change-coral-reef-habitat/" target="_blank">CBS News</a>.</p><p>"Honestly, most sites are out," said Setter in the <a href="https://news.agu.org/press-release/warming-acidic-oceans-may-nearly-eliminate-coral-reef-habitats-by-2100/" target="_blank">statement</a>.</p>
<p>Coral reefs nurture about 25 percent of <a href="https://www.ecowatch.com/tag/marine-life" target="_self">marine life</a> and support local economies worldwide. As <a href="https://www.cbsnews.com/news/climate-change-coral-reef-habitat/" target="_blank">CBS News</a> noted, the new research is disheartening for efforts to restore corals by growing them in labs and then putting them back into the ocean. While those efforts have had a 60 percent success rate, the research suggests that lab-grown corals will not stand up to warming oceans and increased acidification.</p><p>Corals are extremely sensitive to ocean temperatures. When the temperature rises just a couple of degrees, corals experience mass <a href="http://www.ecowatch.com/tag/coral-bleaching" target="_self">bleaching</a>, where coral turns white as it sheds the algae it relies on not only for survival, but also for its magnificent colors, as <a href="https://www.cbsnews.com/news/climate-change-coral-reef-habitat/" target="_blank">CBS News</a> reported. Bleaching does not kill the coral, but it does weaken them, making them vulnerable to disease.</p>
<p>Scientists are predicting a mass bleaching within the next couple of weeks in Australia's <a href="http://www.ecowatch.com/tag/great-barrier-reef" target="_self">Great Barrier Reef</a>. The reef, which is nearly the length of Italy, is undergoing heat stress right now, with patches starting to bleach. While a major widespread bleaching has not occurred yet, scientists have warned that it is likely if high ocean temperatures around the reef do not drop in the next two weeks, as <a href="https://www.theguardian.com/environment/2020/feb/20/great-barrier-reef-on-brink-of-third-major-coral-bleaching-in-five-years-scientists-warn" target="_blank">The Guardian</a> reported.</p><p>Already, temperatures across two-thirds of the reef are about two to three degrees Celsius above normal, with typical peak temperatures still one month away.</p><p>"We are down to the wire," said professor Terry Hughes, director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, according to <a href="https://www.theguardian.com/environment/2020/feb/20/great-barrier-reef-on-brink-of-third-major-coral-bleaching-in-five-years-scientists-warn" target="_blank">The Guardian</a>.</p>
<p>The National Oceanic and Atmospheric Administration has placed the Great Barrier Reef on Alert Level 1 for the next week, meaning significant bleaching is likely, according to the <a href="https://www.abc.net.au/news/2020-02-20/scientists-warn-potential-bleaching-great-barrier-reef/11984626" target="_blank">Australian Broadcasting Company</a>.<br></p><p>"Unfortunately we are a whisker away from bleaching disaster yet again because of global warming-driven marine heatwaves," said Shani Tager from the Australian Marine Conservation Society to the <a href="https://www.abc.net.au/news/2020-02-20/scientists-warn-potential-bleaching-great-barrier-reef/11984626" target="_blank">Australian Broadcasting Company</a>.</p><p>"As underwater heatwaves threaten once again to cook our corals, our politicians must move beyond half-baked plans to tackle global warming."</p>

Siemens has announced it will remain involved in a controversial coal mining project in Australia, despite massive environmental criticism as the country continues to be ravaged by bushfires.
<p>The German engineering conglomerate has a contract worth roughly €18 million ($20 million) which requires Siemens to supply rail infrastructure for the Carmichael mine in Queensland, near the <a href="http://www.ecowatch.com/tag/great-barrier-reef">Great Barrier Reef</a>.</p><p>But <a href="https://www.ecowatch.com/tag/climate-crisis">climate</a> activists from Fridays for Future and Extinction Rebellion staged protests last week in a dozen German cities against the mine, including outside Siemens' Munich headquarters, hoping to change the firm's stance on the project.</p><p>But on Sunday, Siemens' CEO Joe Kaeser tweeted: "We have just finished our special meeting .... We have evaluated all the options and have concluded that we must fulfill our contractual obligations."</p><p>Kaeser did promise, though, that the company would better "manage in the future the questions of protecting the environment."</p>

Australia, Your Country Is Burning — Dangerous Climate Change Is Here With You Now
07 January 2020
Insights + Opinion

By Michael Mann
After years studying the climate, my work has brought me to Sydney where I'm studying the linkages between climate change and extreme weather events.
<p>Prior to beginning my sabbatical stay in Sydney, I took the opportunity this holiday season to vacation in Australia with my family. We went to see the Great Barrier Reef — one of the great wonders of this planet — while we still can. Subject to the twin assaults of warming-caused bleaching and ocean acidification, <a href="https://www.theguardian.com/environment/ng-interactive/2014/mar/great-barrier-reef-obituary" target="_blank">it will be gone</a> in a matter of decades <a href="https://www.bbc.com/news/world-australia-49520949" target="_blank">in the absence of</a> a dramatic reduction in global carbon emissions.</p>
<p>We also travelled to the Blue Mountains, another of Australia's natural wonders, known for its lush temperate rainforests, majestic cliffs and rock formations and panoramic vistas that challenge any the world has to offer. It too is now threatened by climate change.</p><p>I witnessed this firsthand.</p><p>I did not see vast expanses of rainforest framed by distant blue-tinged mountain ranges. Instead I looked out into smoke-filled valleys, with only the faintest ghosts of distant ridges and peaks in the background. The iconic blue tint (which derives from a haze formed from "terpenes" emitted by the Eucalyptus trees that are so plentiful here) was replaced by a brown haze. The blue sky, too, had been replaced by that brown haze.</p><p>The locals, whom I found to be friendly and outgoing, would volunteer that they have never seen anything like this before. Some even uttered the words "climate change" without any prompting.</p><p>The songs of Peter Garrett and Midnight Oil I first enjoyed decades ago have taken on a whole new meaning for me now. They seem disturbingly prescient in light of what we are witnessing unfold in Australia.</p>
<p>The brown skies I observed in the Blue Mountains this week are a product of human-caused climate change. Take <a href="https://www.theguardian.com/australia-news/2019/dec/19/419c-australia-records-hottest-ever-day-one-day-after-previous-record" target="_blank">record heat</a>, combine it with unprecedented <a href="https://www.theguardian.com/environment/2018/jul/19/you-count-your-blessings-farm-families-battling-drought-photo-essay" target="_blank">drought</a> in already dry regions and you get unprecedented bushfires like the ones engulfing the <a href="https://www.theguardian.com/australia-news/2019/dec/28/australian-bushfires-out-of-control-as-heatwave-expected-to-peak-on-new-years-eve" target="_blank">Blue Mountains</a> and spreading <a href="https://time.com/5756714/australia-wildfires/" target="_blank">across the continent</a>. It's not complicated.</p>
<div id="94db3" class="rm-shortcode" data-rm-shortcode-id="QWI2D71578489863"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1211494876610613253" data-partner="rebelmouse"><div style="margin:1em 0">The smoke is so thick in Katoomba tourists are opting for photos with billboards, rather than the Three Sisters the… https://t.co/YbKl0daL8g</div> — Tom Lowrey (@Tom Lowrey)<a href="https://twitter.com/tomlowrey/statuses/1211494876610613253">1577677861.0</a></blockquote></div><p>The warming of our planet — and the changes in climate associated with it — are due to the fossil fuels we're burning: oil, whether at midnight or any other hour of the day, natural gas, and the biggest culprit of all, coal. That's not complicated either.</p><p>When we mine for coal, like the controversial planned Adani coal mine, which <a href="https://www.theguardian.com/business/2017/aug/16/why-adanis-planned-carmichael-coalmine-matters-to-australia-and-the-world" target="_blank">would more than double</a> Australia's coal-based carbon emissions, we are literally mining away at our blue skies. The Adani coal mine could rightly be renamed the Blue Sky mine.</p><p>In Australia, <a href="https://www.smh.com.au/national/nsw/more-than-900-nsw-homes-confirmed-razed-from-bushfires-20191230-p53nj6.html" target="_blank">beds are burning</a>.

<p>Morrison has shown himself to be <a href="https://www.theguardian.com/australia-news/2017/feb/09/scott-morrison-brings-coal-to-question-time-what-fresh-idiocy-is-this" target="_blank">beholden to coal interests</a> and his administration is considered to have conspired with a small number of petrostates <a href="https://www.smh.com.au/environment/climate-change/morrison-s-big-failure-is-his-lack-of-leadership-on-climate-change-20191220-p53lxz.html" target="_blank">to sabotage</a> the recent <a href="https://unfccc.int/cop25" target="_blank">UN climate conference</a> in Madrid ("COP25"), seen as a last ditch effort to keep planetary warming below a level (1.5C) considered by many to constitute <a href="https://www.climaterealityproject.org/blog/why-15-degrees-danger-line-global-warming" target="_blank">"dangerous" planetary warming</a>.</p><p>But Australians need only wake up in the morning, turn on the television, read the newspaper or look out the window to see what is increasingly obvious to many — for Australia, dangerous climate change is <em>already here</em>. It's simply a matter of how much worse we're willing to allow it to get.</p><p>Australia is experiencing a climate emergency. It is literally burning. It needs leadership that is able to recognise that and act.

A loudspeaker on a damaged reef attracts fish. Tim Gordon / University of Exeter
A team of British and Australian scientists have discovered an innovative way to help coral reefs recover from the climate crisis and other human-caused damage: loudspeakers.
<p>A healthy fish population can help fight the degradation of coral reefs, the study's authors explained in <a href="https://www.nature.com/articles/s41467-019-13186-2" target="_blank">Nature Communications Friday</a>, but damaged reefs don't attract as many fish because they don't smell or sound like healthy reefs.</p><p>"Healthy coral reefs are remarkably noisy places – the crackle of snapping shrimp and the whoops and grunts of fish combine to form a dazzling biological soundscape," senior author and University of Exeter professor Steve Simpson explained in a press release received by EcoWatch. "Juvenile fish home in on these sounds when they're looking for a place to settle."</p>

<p>So a team of researchers from the University of Exeter and the University of Bristol in the UK, and Australia's James Cook University and the Australian Institute of Marine Science spent October to December of 2017 in the <a href="https://www.ecowatch.com/tag/great-barrier-reef" target="_self">Great Barrier Reef</a> trying to see if they could replicate these healthy reef sounds in damaged environments.<br></p><p><a href="https://www.washingtonpost.com/climate-environment/2019/12/01/scientists-used-loudspeakers-make-dead-coral-reefs-sound-healthy-fish-flocked-them/?fbclid=IwAR0Ny2b3DK_qz34i2AlxXc1PHVzaRaDIBPlbd_21Bd9LUTkYFMLw53v2nbA" target="_blank">The Washington Post</a> explained their process:</p><blockquote>At the start of fish recruitment season, when fish spawn and mature, the team built 33 experimental reef patches out of dead coral on open sand about 27 yards from the naturally occurring reef. They then fixed underwater loudspeakers to the center of the patches, angling them upward to ensure the sound was distributed evenly in all directions.<br><br>Over 40 nights, the team played recordings from a healthy reef in some of the patches. In other patches, they used dummy speakers that emitted no sounds, and they left a third group of patches untouched.</blockquote><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjExNzU0Ny9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NTExMzg4MH0.uTGQ67mf4qlJtyunuOhXTCCLzFttRCr710hY1pPg_dc/img.jpg?width=980" id="4a8e0" class="rm-shortcode" data-rm-shortcode-id="1204eb080f0f85c49d3a59c0fd4a5a02" data-rm-shortcode-name="rebelmouse-image" />

<p>The result? The reef patches that broadcasted the healthy reef sounds attracted double the number of fish as the other patches, and the fish species drawn to them were 50 percent more diverse. That diversity included species from every section of the food web, from plankton eaters to predators, which is important for reef health.</p><p>"Reefs become ghostly quiet when they are degraded, as the shrimps and fish disappear, but by using loudspeakers to restore this lost soundscape, we can attract young fish back again," Simpson said in the press release.</p><p>The scientists called this process "acoustic enrichment" and think it could be one tool for helping reef ecosystems recover more quickly.</p><p>"Of course, attracting fish to a dead reef won't bring it back to life automatically, but recovery is underpinned by fish that clean the reef and create space for corals to regrow," Australian Institute of Marine Science fish biologist and study author Dr. Mark Meekan said in the press release.</p><video controls id="138a7" width="100%" class="rm-shortcode" data-rm-shortcode-id="ba1b96ff2dd5b7031e23f4be22db1d69" expand="1" feedbacks="true" mime_type="video/mp4" shortcode_id="1575294501265" url="https://roar-assets-auto.rbl.ms/runner%2F15228-Summary-video.mp4" videoControls="true"> <source src="https://roar-assets-auto.rbl.ms/runner%2F15228-Summary-video.mp4" type="video/mp4"> Your browser does not support the video tag. </video><p>However, the researchers urged that it is also important to tackle reef threats like the climate crisis or <a href="https://www.ecowatch.com/tag/overfishing" rel="noopener noreferrer">overfishing</a> directly. And in this they were backed up by scientists not involved in the study.</p><p>"Using acoustic enrichment to help recolonise degraded reefs with essential reef fish is a novel tool which can add to the reef conservation toolbox," Dr. Catherine Head of the Zoological Society of London and the University of Oxford told <a href="https://www.theguardian.com/environment/2019/nov/29/sonic-youth-healthy-reef-sounds-lure-young-fish-to-degraded-areas" target="_blank">The Guardian</a>. "Our biggest tool in the fight for coral reefs is the 2016 Paris climate change agreement to curb global CO2 emissions, and we must continue to put pressure on governments to fulfil this agreement alongside doing our bit to reduce our own carbon footprints."</p>
