AUSTRALIAN SCIENTISTS DISCOVER 500 METER TALL CORAL REEF IN THE GREAT BARRIER REEF–FIRST TO BE DISCOVERED IN OVER 120 YEARS
CAPE YORK, AUSTRALIA – Scientists have found an enormous indifferent coral reef within the Nice Barrier Reef–the primary to be found in over 120 years, Schmidt Ocean Institute introduced at the moment. Measuring greater than 500m excessive–taller than the Empire State Constructing, the Sydney Tower and the Petronas Twin Towers–the reef was found by Australian scientists aboard Schmidt Ocean Institute’s analysis vessel Falkor, at the moment on a 12-month exploration of the ocean surrounding Australia.
The reef was first discovered on Oct. 20, as a staff of scientists led by Dr. Robin Beaman from James Cook dinner College was conducting underwater mapping of the northern Nice Barrier Reef seafloor. The staff then performed a dive on Oct. 25 utilizing Schmidt Ocean Institute’s underwater robotic SuBastian to discover the brand new reef. The dive was live-streamed, with the high-resolution footage seen for the primary time and broadcast on Schmidt Ocean Institute’s web site and YouTube channel.
The bottom of the blade-like reef is 1.5km-wide, then rises 500m to its shallowest depth of solely 40m beneath the ocean floor. This newly found indifferent reef provides to the seven different tall indifferent reefs within the space, mapped for the reason that late 1800s, together with the reef at Raine Island–the world’s most necessary inexperienced sea turtle nesting space.
“This sudden discovery affirms that we proceed to search out unknown constructions and new species in our Ocean,” mentioned Wendy Schmidt, co-founder of Schmidt Ocean Institute. “The state of our information about what’s within the Ocean has lengthy been so restricted. Due to new applied sciences that work as our eyes, ears and arms within the deep ocean, we have now the capability to discover like by no means earlier than. New oceanscapes are opening to us, revealing the ecosystems and various life kinds that share the planet with us.”

Does it strike anybody else as odd, that they’ll declare, with certainty, that half of the Nice Barrier Reef is useless, whereas not realizing that there was a skyscraper-sized pinnacle reef sitting proper underneath their noses?
Why does it all the time shock the “scientists” once they uncover wholesome, thriving coral reefs?
It appears as if each newly found reef is wholesome and thriving… notably whether it is in a distant space and never frequented by vacationers and scuba divers.
Why are these distant reefs miraculously resistant to Gorebal Warming and Ocean Neutralization, whereas the reefs crawling with vacationers and scuba divers are usually not?
Extra Thoughts-boggling Details About Coral Reefs
Coral reefs can deal with “extremely acidic ocean waters”…
Pacific Thriller: Coral Reefs Are Thriving, However How?
Jun 5, 2015
A Faculty of Geosciences researcher and her colleagues have discovered wholesome coral reefs in extremely acidic ocean waters. “The reefs seem like thriving, and we need to perceive why,” says Kathryn Shamberger, assistant professor of oceanography.
The staff examined eight coral reefs within the Palauan archipelago and located excessive ranges of acidification throughout the lagoons and inlets of the Palau Rock Islands. However regardless of the excessive ranges, the Rock Island coral reefs seem like extraordinarily wholesome.
“Based mostly on lab experiments and different research, that is the alternative of what we anticipated,” says Barkley, the lead writer.
The staff says that the acidification course of in Palau is a pure one, on account of a mixture of organic exercise and the sluggish flushing of water by means of the Rock Island lagoons that enables acidification ranges to construct up over time.
Sediment laden waters…
Coral reef thriving in sediment-laden waters
Fast charges of coral reef progress have been recognized in sediment-laden marine environments, situations beforehand believed to be detrimental to reef progress.
A brand new research has established that Center Reef – a part of Australia’s iconic Nice Barrier Reef – has grown extra quickly than many different reefs in areas with decrease ranges of sediment stress.
Rising seas (AKA deeper water)…
Nice Barrier Reef discovered to have thriving deep water coral
Up to date 2:23 AM ET, Fri October 26, 2012
A latest survey of the Coral Sea and Nice Barrier Reef has discovered coral flourishing in deep waters, a stark distinction to the shallower reefs which have seen a drastic decline over the previous few a long time.
The wholesome coral populations have been found to be beneath 30 meters — past the same old attain of most scuba divers — and even discovered at depths of 80 meters, in accordance with the Catlin Seaview Survey.
Rottnest’s tropical corals discovered to thrive
July 9, 2015 by Kerry Faulkner
Researchers are stunned at thriving coral progress at Rottnest Island, predicting its smaller coral communities may develop right into a reef just like the one which existed there within the Final Interglacial, roughly 130,000 years in the past.
Hong Kong coral reef thrives regardless of air pollution
Amid main developments, territory’s scientists make unexpectedly nice underwater discovery.
08 Oct 2015
Marine life is flourishing regardless of main developments at Hong Kong’s busy harbour.
Like some other marine surroundings around the globe, this area is feeling the impacts of local weather change and improvement.
Nonetheless, the stronger kinds of coral species are holding on regardless of the unrelenting situations and scientists at the moment are attempting to ascertain how they survive.
Scientific Evaluation Of Curaçao’s Coastal Waters Present Wholesome And Thriving Coral And Fish Populations
WILLEMSTAD – A latest two-week lengthy scientific evaluation surveyed over 150 dive websites of Curaçao’s shallow water reef websites and located indicators of wholesome coral and fish populations across the island, notably in Oostpunt. The scientific evaluation was a essential step in Blue Halo Curaçao and its complete, science-based method to ocean zoning.
An absence of information…
For marine biologists, the destruction of the reefs has confirmed to be as irritating as it’s heartbreaking. As a result of reef habitats are so advanced, and since worldwide reef monitoring and mapping efforts solely started somewhat over a decade in the past, scientists merely do not need sufficient data to maintain tabs on the destruction of the reefs, not to mention give you an efficient resolution. On the fee the reefs are disappearing, they could be past restore by the point a complete plan to save lots of reefs might be put into place…
Harsh intertidal zones…
A Various Assemblage of Reef Corals Thriving in a Dynamic Intertidal Reef Setting (Bonaparte Archipelago, Kimberley, Australia)
The susceptibility of reef-building corals to climatic anomalies is nicely documented and a explanation for nice concern for the way forward for coral reefs. Reef corals are usually thought-about to tolerate solely a slender vary of weather conditions with solely a small variety of species thought-about heat-tolerant. Often nevertheless, corals might be seen thriving in unusually harsh reef settings and these are trigger for some optimism about the way forward for coral reefs. Right here we doc for the primary time a various assemblage of 225 species of laborious corals occurring within the intertidal zone of the Bonaparte Archipelago, north western Australia.

JULY 13, 2015
JARDINES DE LA REINA, Cuba —
The sharks are a vacationer attraction — at two of the numerous diving spots within the Gardens, they’re fed to make sure bigger numbers — however to scientists like Dr. Pina and Dr. Kritzer, their very presence right here is an indicator of the coral reef’s robustness.
Analysis has linked the well being of reefs to habitation by giant fish, and the absence of sharks and different prime predators is commonly an indication of a reef in decline.
The resilience of this coral reef appears past query. The waters contained in the protect maintain 10 instances as many sharks as outdoors, Dr. Pina mentioned, and goliath grouper, uncommon in lots of locations, are sometimes seen right here.
Glass sponge reefs regarded as extinct are found to be thriving in ocean depths
Mummies, they’re known as, these unusual shapes that type one of many largest constructions ever to exist on Earth. Stretching some 2900 kilometers from Spain to Romania, the lengthy, sinuous curve of thousands and thousands of mummies—once-living, vase-shaped animals—is a fossil reef. In its heyday within the Jurassic, the reef dwarfed at the moment’s Nice Barrier Reef off Australia’s northeastern coast. Now it’s seen solely in rock outcrops dotted throughout an enormous space of central and southern Spain, southwestern Germany, central Poland, southeastern France, Switzerland, and japanese Romania close to the Black Sea. The traditional reef was made up not of corals however of deep-sea sponges known as hexactinellids.
Hexactinellids, or glass sponges, use silica dissolved in seawater to fabricate a skeleton of four- or six-pointed siliceous spicules. Particular person glass sponges, akin to the attractive Venus’s flower-basket sponge (Euplectella aspergillum), are nonetheless discovered within the deep sea however are a unique genus and species from the Jurassic reef-builders. Reef-building glass sponges, identified solely from fossilized stays, are thought to have gone extinct 100 million years in the past, pushed out by competitors from newly arrived diatoms.
The shock discover
The darkness beneath British Columbia’s Strait of Georgia, Hecate Strait, and Queen Charlotte Sound hid the subsequent chapter in an eons-old story. For many years, hints of one thing alive—one thing nobody had seen earlier than—washed up on the shores of Galiano Island within the Strait of Georgia. Strolling alongside a seashore on the island, long-time resident Elizabeth McClelland discovered items of an unidentified object within the tide line. “On occasion, I’d come throughout bits of flotsam that have been very delicate however very sharp,” says McClelland. “My granddaughter as soon as discovered a reasonably large piece of those unknown presents from the ocean.”
Then got here an odd clue on the backside of Hecate Strait. Throughout a 1984 seafloor mapping expedition, scientists from the Geological Survey of Canada, utilizing sonar imaging, noticed mounds over large areas of the seafloor—areas that ought to have been utterly flat. Related acoustic anomalies, as geological survey scientists Kim Conway and Vaughn Barrie referred to them, have been noticed once more in 1986 throughout a survey of Queen Charlotte Sound.
Reef-building glass sponges gave up their secret to Conway and Vaughn in 1987: underwater pictures in Hecate Strait captured the sponges on movie. Removed from extinct, the sponges have been thriving within the depths off British Columbia.

Corals in Musandam are thriving, report finds
MUSANDAM // A survey of the peninsula by an expedition of marine scientists and volunteer divers has discovered that its coral reefs are thriving.
For Dr Jean-Luc Solandt, an expedition member and one of many authors of the report, mentioned when it got here to the well being of corals, the websites have been in higher situation than many places well-known for being scuba-diving haunts.
“It’s an excellent location,” mentioned Dr Solandt, senior biodiversity coverage officer on the Marine Conservation Society. “The coral well being is great.”
The wholesome Musandam reefs may nicely be a supply of inhabitants restoration for reefs within the Arabian Gulf, the place bodily and man-made components mix to create an surroundings that is tougher for corals.
Lots of the websites hosted very giant colonies of the genus Porites. Among the colonies, mentioned Dr Solandt, have been “the dimensions of small homes”, indicating they may nicely be greater than 400 years outdated.
This additionally most probably meant that no vital damaging occasions had occurred inside this timeframe, mentioned the report.
It appears to me that that scuba divers are likely to whine greater than different teams about Gorebal Warming and Ocean Neutralization killing coral reefs. I’ve additionally seen variations of this in a number of articles…

Deep-Water Coral Reefs Thriving Off Puerto Rico
Jan 14, 2011
SAN JUAN, Puerto Rico – Because the ocean flooring plunges off southwestern Puerto Rico, it reveals coral reefs dotted with bright-blue sea squirts and a large number of different organisms whose existence has given hope to scientists who try to save lots of the island’s threatened ecosystems.
The organisms are an integral a part of a bunch of reefs found to be thriving close to an space the place most shallow coral reefs and the fish that depend upon them are sick general.
The reefs – at a depth of as much as 500 toes (152 meters) in an space 12 miles (19 kilometers) throughout – have been lately found as a part of a federally funded mission to conduct analysis on deep-water corals, in accordance with the U.S. Nationwide Oceanic and Atmospheric Administration.
“We stumbled throughout this space,” Richard Appeldoorn, a professor on the College of Puerto Rico in Mayaguez who was concerned within the mission, instructed The Related Press on Thursday.
Divers enrolled in a one-year coaching course to depths of as much as 100 toes (31 meters) seen the thriving reefs and huge predators lurking close by, mentioned Appeldoorn, who oversees the college’s fisheries, biology and coral reef research program.

Coral reefs, the nice survivors
By Viv Forbes
For not less than fifty years, agitated lecturers have been predicting the top of Australia’s Nice Barrier Reef. Now worldwide “specialists” are additionally sprouting coral calamity. However regardless of the alarms, the reef continues to be there.
Corals are among the many biggest survivors on Earth and have been right here for about 500 million years. Lots of the kinds of corals discovered on reefs at the moment have been current in related kinds on reefs 50 million years in the past.
Since corals first appeared there have been 5 mass extinctions when over 50% of all life kinds on land and within the seas died.
Corals additionally survived a number of lethal ice ages when sea ranges fell so low that many coral reefs left their skeletons stranded as limestone hills on dry land. However all the time some colonisers adopted the retreating seas and survived.
Then got here the new local weather eras when the nice ice sheets melted and sea ranges rose dramatically. Some coral reefs drowned, however others simply constructed on prime of the outdated drowned corals forming the attractive coral atolls we see at the moment. Corals flourish in gently rising seas akin to we have now at the moment – it offers them room to refresh and develop vertically.
And if the water will get too heat, coral larvae simply drift into cooler waters nearer to the poles. The Nice Barrier Reef would transfer slowly south.
Corals have outlasted the dinosaurs, the mammoths and the sabre-toothed tiger. Captain Cook dinner’s ship was virtually disembowelled by the sturdy corals of the Nice Barrier Reef in 1770. If Cook dinner got here again at the moment, he can be unable to detect any modifications within the Reef.
It doesn’t matter what the longer term holds, corals are extra probably than people to outlive the subsequent main extinction.
Within the occasion of yet one more Ice Age we should hope that reef alarmists haven’t denied us the issues we might want to survive – meals, vitality, chemical substances, shelter, concrete and metal generated by carbon fuels.

Coral flourishing at Bikini Atoll atomic take a look at website
Tue Apr 15, 2008
By Rob Taylor
CANBERRA (Reuters) – Coral is once more flourishing within the crater left by the biggest nuclear weapon ever detonated by the USA, 54 years after the blast on Bikini Atoll, marine scientists mentioned on Tuesday.
A staff of analysis divers visited Bravo crater, floor zero for the take a look at of a thermonuclear weapon within the distant Marshall Islands on March 1, 1954, and located giant numbers of fish and coral rising, though some species appeared regionally extinct. “I didn’t know what to anticipate, some type of moonscape maybe. Nevertheless it was unimaginable,” Zoe Richards, from Australia’s James Cook dinner College, instructed Reuters in regards to the staff’s journey to the atoll within the south Pacific.
“We noticed communities not too removed from any coral reef, with loads of fish, corals and motion happening, some actually putting particular person colonies,” she mentioned.

Ocean acidification doesn’t have an effect on the physiology of the tropical coral Acropora digitifera throughout a 5-week experiment
A. Takahashi, H. Kurihara
The rise in atmospheric CO2 focus, which has resulted from the burning of fossil fuels, is being absorbed by the oceans and is inflicting ocean acidification. Ocean acidification entails the lower of each the pH and the calcium carbonate saturation state. Ocean acidification is predicted to impression the physiology of marine organisms and scale back the calcification charges of corals. Within the current research, we measured the charges of calcification, respiration, photosynthesis, and zooxanthellae density of the tropical coral Acropora digitifera underneath near-natural summertime temperature and daylight for a 5-week interval. We discovered that these key physiological parameters weren’t affected…
Moreover, there was no vital correlation between calcification fee and seawater aragonite saturation (Ωarag). These outcomes counsel that the impacts of ocean acidification on corals physiology could also be extra advanced than have been beforehand proposed.

GALVESTON, Texas — When you concentrate on Galveston, you most likely image solar and surf, possibly the Pleasure Pier or typically seaweed, however you most likely don t take into consideration nice diving.
The sanctuary really encompasses three separate areas, underwater salt domes that stand larger than the encircling ocean flooring. Snapper and grouper fishermen who noticed the colourful sponges and different marine life underneath their boats are credited with discovering the ecological marvel within the late 19th century. The world was designated as a nationwide marine sanctuary in 1992 and it s now managed underneath the course of the Nationwide Oceanic and Atmospheric Administration.
At a time when coral reefs around the globe are in decline, Flower Backyard Banks is flourishing largely as a result of it s so distant it attracts comparatively few divers.
I’m actually starting to assume that the one factor coral reefs can’t deal with are too many scuba divers.

What’s so particular about Little Cayman’s reefs? That’s the query a brand new $140,000 scientific research on the Central Caribbean Marine Institute will search to reply.
Scientists need to decide why reefs across the distant island are thriving and whether or not there are classes that may be tailored to assist defend and preserve important coral reef methods around the globe.
The brand new research will look particularly at uncommon and endangered coral species round Little Cayman and try to find out why they’re bucking a development of widespread decline in coral reefs throughout the Caribbean.
An earlier research by CCMI confirmed that coral cowl had been growing round Little Cayman over the previous 5 years.

Coral reefs even dealt with the a lot hotter Eemian (Sangamonian) interglacial stage…
Sangamon Interglacial: Paleoclimatology
and Future Local weather Implications
Latest ‘excessive’ climate occasions, rising carbon dioxide ranges and the rising proof of retreating glaciers have more and more turn out to be the themes of a lot debate within the in style press and quite a few fields of scientific analysis. Driving these discussions are questions aimed toward discerning what drives the local weather on Earth. A number of have been famous in earlier analysis: Milankovitch cycles, photo voltaic output, continental configurations and the newest and controversial, carbon dioxide and different greenhouse fuel atmospheric concentrations (Hambrey 2004). With the intention to perceive what we must always anticipate, each from a local weather change perspective and from a altering biogeographical perspective throughout our present interglacial section, scientists have regarded to the final interglacial interval within the geologic report, the Sangamon Stage (or the Eemian, because it seems in European literature) roughly 114,000 – 130,000 years in the past for solutions.
Equally, the limestones deposited in coral reef complexes close to Bermuda, the Florida Keys and a part of the Miami Limestone needed to have been fashioned in seas which are anyplace from 6 to 19 meters larger than present sea degree with most sea degree estimates being positioned at 6 – 10 meters larger than at the moment. These values symbolize knowledge gathered throughout 2 of the decrease sea stands in the course of the Sangamon with the third being a lot larger than the others based mostly on ?O18 minimums obtained from oxygen isotope knowledge of deep sea cores (USGS).
The implications of such a excessive sea degree means that huge modifications in quite a lot of the weather that issue into establishing a selected world local weather regime needed to have occurred. Milankovitch cycles, the Northern Hemisphere, in the course of the Sangamon, would have acquired larger insolation charges (photo voltaic radiation acquired on a floor throughout a unit of time) than at the moment and a big portion of Greenland’s Ice Sheet and vital parts of the West Antarctic Ice sheet would have needed to soften to provide the ocean degree rise vital for coral reef derived limestone formations to have been generated on the elevations that they’re current at at the moment (Koerner).
Carbon dioxide concentrations weren’t as excessive within the Sangamon as they’re at the moment, however they have been nonetheless a lot larger than any of the earlier or following glacial durations. This mix of excessive CO2 and elevated insolation on account of Milankovitch cycle parameters would have altered the local weather regimes across the globe. International temperatures have been regarded as 5-7 °C (9-13 °F) larger than the present interglacial interval in accordance with North Atlantic oceanic sediment cores with South Pacific oceanic cores exhibiting an increase of solely 3-5 °C (5.4-9 °F).
Throughout the vast majority of Europe, basic scientific consensus was that the Eemian local weather was a lot hotter and wetter than at the moment’s surroundings. This resulted within the improvement of huge temperate forests and the fast growth of species, most notably Carpinus throughout the realm (Turner 2000). Though the Eemian was persistently a lot hotter, proof has been constructing that a big scale late Eemian arid ‘pulse’ dominated central Europe ensuing within the widespread takeover of ecological niches by varied grasses and shrubby bushes earlier than returning to a heat, considerably extra moist local weather dominated by temperate forests simply earlier than the newest glacial stadial (Sirocko, et al. 2005).
Coupled with the climatic discrepancies are the discrepancies with analyzing how life will reply to the altering surroundings. As Smith and Buddemeier defined, oceanic chemistry and quite a lot of different components, an increase in sea degree may really profit most coral reef complexes if sea degree and atmospheric carbon dioxide concentrations rise at anticipated charges throughout the subsequent 100 years. The web impact would trigger a drawdown of atmospheric carbon dioxide as extra of this greenhouse fuel will get included as CaCO3 as varied reef complexes develop. Total, Smith and Buddemeier make a legitimate level once they clarify that the variety of components affecting coral reef well being and viability, coupled with the modest modifications anticipated from varied local weather change simulations point out that on a world scale, coral reefs are unlikely to be adversely affected by projected local weather change. It is just on the native scale that coral reef communities may very well be in danger.
Thankfully for coral reefs, there have been no scuba divers 130,000 years in the past.

Science Options – Discoveries of the Deep—The Stunning Undersea World at Pulley Ridge
Within the deep waters of the Gulf of Mexico, roughly 250 km west of Cape Sable, Florida, and 70 km west of the Dry Tortugas, are a sequence of drowned barrier islands often called Pulley Ridge. The ridge was present in 1950, nevertheless it wasn’t till latest years that scientists found one thing extraordinary.
The southern portion of the ridge is a thriving coral reef, a pristine habitat teeming with life and shade. Right here, greater than 60 species of fish swim in predominantly clear, heat water. An abundance of algae sprinkles the seascape in vibrant reds and greens. Good blue-purple corals stretch throughout the ocean flooring like big plates. Octocorals, with tiny featherlike tendrils and colours that change per colony, attain out with typically mild and delicate and typically vibrant and knobby arms. And within the smooth mild that filters down from the distant floor, luxuriant fields of the leafy algae Anadyomene menziesii rise from the ocean flooring like patches of lettuce at nightfall.
The reef was found in 1999, as scientists and graduate college students from the USGS Heart for Coastal & Watershed Research and the College of South Florida (USF) boarded the analysis vessel Bellows and set sail for the Pulley ridge space, the place a bathymetric map of the ocean flooring confirmed a mysterious bump.

Hybrid Corals: Intercourse Gone Awry or Saving Grace?
As the complete moons of late summer time and fall rise, so too, does the libido of threatened staghorn (Acropora cervicornis) and elkhorn (Acropora palmata) corals.
By Marah J. Hardt on September 25, 2014
As the complete moons of late summer time and fall rise, so too, does the libido of threatened staghorn (Acropora cervicornis) and elkhorn (Acropora palmata) corals. Woke up from a yr of sexual slumber, every species shakes off the shackles of celibacy to interact in a mass-spawning a number of days after the brightest nights. Going through declines of as much as 97 % up to now 30 years, these two species have been overwhelmed again by illness, air pollution, overfishing and local weather change. Their yearly spawning must be a time of celebration. However after thousands and thousands of years of profitable group intercourse, the very act of replica might now be contributing to their final demise.
A report this summer time provides to a rising physique of proof that one other coral, Acropora prolifera, could also be overtaking reef actual property previously occupied by elkhorns and staghorns. Removed from a international invader, genetic exams present this coral is actually the offspring of an elkhorn and staghorn cross. A. prolifera is a hybrid. And its obvious rise is a sign of coral intercourse gone awry.
If Acropora cervicornis and Acropora palmata can interbreed to provide genetically viable offspring (Acropora prolifera), they don’t seem to be distinct species and shouldn’t be listed as endangered species. Acropora is just not endangered, prolifera ought to be an enormous, fats clue.
Coral reefs seem like adapting fairly nicely to local weather change and Rooster Little of the Sea, if not adapting so nicely to scuba divers, snorkelers, agricultural runoff and idiots fishing with dynamite.
Coral reefs actually do appear to love heat water and plenty of CO2 of their diets…
The Eniwetok/Bikini coral reef advanced dates again to the Eocene, when seawater pH was a lot decrease than at the moment.
Oddly sufficient, there may be an unconformity between the Eocene and Miocene. There was apparently little or no coral progress in the course of the Oligocene, a interval of world cooling and falling sea degree.
