Deep-sea survey of Australian marine parks reveals striking species

Posted On Feb 10 2020 by

first_imgA monthlong survey of deep-sea seamounts in and around Australia’s Huon and Tasman Fracture marine parks has revealed a spectacular range of species, from feathery corals and tulip-shaped glass sponges to bioluminescent squids and ghost sharks.Researchers surveyed 45 seamounts and covered 200 kilometers (124 miles), collecting 60,000 stereo images and some 300 hours of video.Close to the surface, they recorded data on 42 seabird species and eight whale and dolphin species. The researchers also used a net to collect some animals from the seamounts for identification, many of which are potentially new to science. South of Tasmania, hundreds of undersea mountains mark the deep ocean floor. Now, a monthlong survey of these seamounts in and around Australia’s Huon and Tasman Fracture marine parks has revealed a spectacular range of deep-sea species, from feathery corals and tulip-shaped glass sponges to bioluminescent squids and ghost sharks. The survey team has also uncovered more than 100 previously unnamed species that are likely new to science.The seamounts within the marine parks occur at depths of 700 to 1,500 meters (2,300 to 4,900 feet). These mountains are home to cold-water corals that are slow-growing, fragile and threatened by fishing, deep-sea mining and climate change-induced variations in sea temperature and acidity. But accessing these harsh, dark, high-pressure depths is extremely hard. So scientists and park managers went aboard the Investigator, a research ship that’s part of Australia’s Marine National Facility, and used a special camera system designed by staff at the Australian government’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) to see what lies thousands of feet beneath the ocean’s surface.The deep-tow system, weighing about 350 kilograms (770 pounds), has four cameras secured within high-strength aluminium housings, and a fiber-optic cable that feeds real-time footage of the deep-sea floor back to the ship. During the monthlong exploration, the researchers surveyed 45 seamounts using the deep-tow cameras, voyage chief scientist Alan Williams of CSIRO said in a statement. They covered 200 kilometers (124 miles) and collected 60,000 stereo images and some 300 hours of video. The footage captured hundreds of corals, including the main reef-building stony coral (Solenosmilia variabilis) and many other soft corals.“While it will take months to fully analyse the coral distributions, we have already seen healthy deep-sea coral communities on many smaller seafloor hills and raised ridges away from the seamounts, to depths of 1450 meters [4,760 feet],” Williams said in the statement. “This means that there is more of this important coral reef in the Huon and Tasman Fracture marine parks than we previously realised.”Yellow stony coral on a seamount.

And close to the surface of the sea, they recorded data on 42 seabird species and eight whale and dolphin species. The researchers also used a net to collect some animals from the seamounts for identification. Many species, as one would expect from remote areas, were potentially new to science.“For several of the museum taxonomists onboard, this was their first contact with coral and mollusc species they had known, and even named, only from preserved specimens,” Williams and Nic Bax, director of CSIRO’s NERP Marine Biodiversity Hub, write in the Conversation.In one of the seamounts, the team saw what they say is the “world’s only known aggregation of deep-water eels.”“We have sampled these eels twice before and were keen to learn more about this rare phenomenon,” Williams and Bax write. “Using an electric big-game fishing rig we landed two egg-laden female eels from a depth of 1,100 metres [3,610 feet]: a possible first for the record books.”The areas now under the protection of the Tasman Fracture commonwealth marine reserve (created in 2007) and Huon commonwealth marine reserve (established in 1999), were once heavily fished by trawlers. Researchers say the present surveys can shed light on both what grows in the deep-sea environments, and if corals that were damaged by bottom-trawling are recovering after 20 years of protection.“While we saw no evidence that the coral communities are recovering, there were signs that some individual species of corals, featherstars and urchins have re-established a foothold,” Williams said.A brittlestar.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredcenter_img Article published by Shreya Dasguptalast_img read more


Champions League final: Ronaldo vs Salah battle awaits Kiev

Posted On Nov 18 2019 by

first_imgFor once in a Champions League final, Cristiano Ronaldo will yield some of the spotlight to another player sweeping up adulation and personal acclaim.While five-time world player of the year Ronaldo is chasing a record fifth Champions League triumph, and fourth with Real Madrid, Liverpool forward Mohamed Salah is chasing a first. Not just a first Champions League success, but a first major title in football in his maiden cup final.Victory in Kiev’s Olympic Stadium on Saturday would be a fitting climax to an astonishing debut season at Liverpool for Salah. A season when the Egyptian seized his second chance at a Premier League club with gusto after a faltering spell at Chelsea.Champions League final: History beckons Cristiano Ronaldo in KievSalah has had such a devastating impact that he poses a serious threat to the decade of dominance of the world player of the year award by Ronaldo and Barcelona’s Lionel Messi.”Comparing players with Ronaldo and Messi is something you can’t do,” Real Madrid captain Sergio Ramos said on Friday. “They’re in another orbit. There are players who are in fashion, those who come and go and others who stay around.Champions League final: Key tactical factors in Real Madrid vs Liverpool”Salah is a top player, that’s clear. He’s shown that this year and he’s got a great chance to show that over the next few years as Ronaldo and Messi have done – but the day after tomorrow.”While lacking the flashy touch of Ronaldo, and presenting the image of a more modest lifestyle on social media, the “Egyptian King” is as adept at harnessing his commercial appeal. In recent weeks, Salah could be found at news conferences promoting a cellphone company, a logistics firm and taxi service. No wonder Salah is making the most of his newly-elevated status in the global game. In 2014, when Ronaldo reached the first of his four Champions League finals with Madrid, Salah was just completing his first five months drifting in and out of the Chelsea team.advertisementChampions League final: Beckham asks Zidane to ‘please beat Liverpool’Salah never settled and was eventually discarded by the west London club after only 13 appearances under Jose Mourinho. In Italy, a career stalling was reignited at Roma and Liverpool came calling last year.Champions League final: Liverpool manager Klopp praises fighter ZidaneFew could have imagined Salah’s impact, powering the five-time European champions to their first Champions League final in 11 years with 11 goals in a run that began in the playoff round. Ronaldo eclipsed Salah in the competition with 15 goals after starting out in the group stage.Ouch! 1000 Liverpool fans stranded ahead of Champions League finalBut both Salah and Ronaldo stand locked on 44 goals for the season in all competitions heading into the final. So potent is the 33-year-old Ronaldo, he only required 43 games. Salah, who is eight years younger, played eight more than the Portuguese.Champions League final: Real Madrid, Liverpool name blockbuster squads”He’s the best,” Madrid coach Zinedine Zidane said of Ronaldo, “and he proves it every year.”Particularly in Europe, where Ronaldo is the all-time leading Champions League scorer with 120 goals. Real Madrid is seeking a record-extending 13th European club title.Champions League final: Mane sends 300 Liverpool jerseys to his village”When you’re at this club you cannot take your foot off the gas, least of all in this competition,” Ronaldo said. “I love that side of it because it motivates me a lot.”While Madrid and Liverpool are contesting the biggest prize in club football, they were far off the pace in their home leagues.Third in the Premier League still represented progress for Liverpool under Juergen Klopp, who previously finished sixth, eighth and fourth.But Madrid regressed in La Liga, surrendering its title with a third-place finish. Madrid has won the Champions League three times in the last four years, with two produced by Zidane early into his first managerial job. It might take retaining the European Cup for Zidane to remain in the post.”To reach a final is not easy,” Zidane reminded his critics. “This is beautiful. This is my passion, I’ve always been a good competitor, I like to compete and behind all that is a lot of hard work. Not only on my part but also the players. If you like to compete and want to work hard you can achieve what we are doing.”Klopp’s grip on the Liverpool job will not be impacted by Saturday’s result but victory would put the brakes on a run of five cup finals losses, including in the 2013 Champions League decider to Bayern Munich while Borussia Dortmund manager.advertisement”I know how I lost the finals, it didn’t change my life,” said Klopp, a two-time Bundesliga champion with Dortmund. “It’s not that I wake up every morning and think, ‘Wow. That was a big chance.'”(With AP inputs)last_img read more
