Hebrew University of Jerusalem Over 35 years, a 40% reduction in calcium carbonate deposits in Australia’s Great Barrier Reef An expedition from the Hebrew University of Jerusalem and the Carnegie Institute of Science has measured a roughly 40% reduction in the rate of calcium carbonate deposited in Australia’s Great Barrier Reef in the last 35 years — a scenario that could damage the reef framework and endanger the entire coral ecosystem. Coral reefs are the most ecologically...

Ken Caldeira, Carnegie Institution A team of researchers working on a Carnegie expedition in Australia’s Great Barrier Reef has documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown. In a quest for historical context on the peril facing coral reefs, the team compared current measurements of the growth rate of a section of Australia’s Great Barrier...

Great Barrier Reef Is An Effective Wave Absorber: Study
2014-09-19 03:25:13

University of Southampton New research has found that the Great Barrier Reef, as a whole, is a remarkably effective wave absorber, despite large gaps between the reefs. This means that landward of the reefs, waves are mostly related to local winds rather than offshore wave conditions. As waves break and reduce in height over reefs, this drives currents that are very important for the transport of nutrients and larvae. This reduction in wave height also has implications for shoreline...

ARC Centre of Excellence in Coral Reef Studies One of Australia’s leading coral reef ecologists fears that reef biodiversity may not provide the level of insurance for ecosystem survival that we once thought. In an international study published September 15, Professor David Bellwood from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) says we need to identify and protect the most important species within reef ecosystems. In coral reefs, just as in any modern-day...

Great Barrier Reef Shark Populations Impacted By Coral Health And No-fishing Zones
2014-09-15 03:50:53

PLOS Sharks in no-fishing zones in the Great Barrier Reef (GBR) Marine Park are more abundant when the coral is healthy, according to a study published September 10, 2014 in the open-access journal PLOS ONE by Mario Espinoza from James Cook University, Australia and colleagues. Shark species that use coral reefs may be under pressure from fishing, habitat degradation, and climate change. The authors of this study were interested in understanding the factors that affect the distribution...

Scientists Working To Protect Australia's Great Barrier Reef
2014-07-03 14:37:23

Brett Smith for redOrbit.com - Your Universe Online Australian scientists are studying degraded reefs off the Northwest Australian coast as the country marks a decade since a massive rezoning of the Great Barrier Reef Marine Park. “Reefs north of Exmouth have experienced large-scale bleaching in the past five years,” said Malcolm McCulloch from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at the University of Western Australia. The marine biology team is busy...

More Coral Babies Staying At Home On Future Reefs
2014-04-29 03:11:08

Nova Southeastern University It seems that coral reefs are experiencing something their human counterparts have been for years – a shrinking "empty nest" syndrome. That's right – researchers have found that increasing ocean temperatures due to climate change will soon see reefs retaining and nurturing more of their own coral larvae, leaving large reef systems less interconnected. The study brought together an international group of researchers from NSU's Oceanographic Center; the...

Great Barrier Reef Could Be In Danger Due To Proposed Sediment Dump
2014-02-03 04:48:30

redOrbit Staff & Wire Reports - Your Universe Online The Australian federal government has approved a proposal to dump three million cubic meters (106 million cubic feet) of sediment in the Great Barrier Reef, enraging conservationists who believe the move could threaten the world’s largest coral reef system. According to CNN’s Euan McKirdy, the depositing of the dredged material comes as the result of a planned coal port expansion at Abbot Point on the coast of Queensland. The...

High Resolution Map Great Barrier Reef
2013-11-29 13:27:33

[ Watch The Video: Mapping The Great Barrier Reef ] Brett Smith for redOrbit.com - Your Universe Online The remote and unique nature of much of the Great Barrier Reef has long prevented the creation of comprehensive maps of this unique undersea ecosystem. Using satellite data, researchers from James Cook University in Australia and the German company EOMAP recently generated a series of high-resolution 3D maps of the Great Barrier Reef. The researchers said their maps of 135,000...

Short-spined Crown-of-thorns Starfish, Acanthaster brevispinus
2013-08-12 14:37:20

The short-spined crown-of-thorns starfish (Acanthaster brevispinus) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that includes the Great Barrier Reef, the Philippines, and the Seychelles in the Indian Ocean. Because these areas are so far away from one another, the full range of this starfish cannot be known, but it can be said that it resides in a tropical or subtropical environment. It was first discovered by W.K. Fisher, who...

Barrier Reef Anemonefish, Amphiprion akindynos
2012-05-11 12:04:43

The Barrier Reef Anemonefish (Amphiprion akindynos) is native to the marine lagoons and reefs in the Western Pacific Ocean.  It lives at a depth of around eighty-two feet in temperatures fluctuating between fifty degrees Fahrenheit to 89.6 degrees Fahrenheit. Its range includes northern New South Wales, the Loyalty Islands, Tonga, New Caledonia, Coral Sea, and the Great Barrier Reef. They are typically seen near or within the tentacles of their host anemones. They will inhabit anemones like...

Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...

Elongate Surgeonfish, Acanthurus mata
2012-04-02 17:23:07

The Elongate Surgeonfish, (Acanthurus mata), is a species of tropical fish found in the Indo-Pacific, and can be found as far north as Southern Japan and south to the Great Barrier Reef. Some also live as far west as South Africa and as far east as the Tuamotu Islands. Its main habitat is steep slopes around coral reefs. This is a light blue fish with numerous brown stripes running down the length of the body, although over time it is able to change color to become blue overall. It has a...

The Pajama Cardinalfish (Sphaeramia nematoptera) is a fish that belongs to the Apogonidae family. These fish are a popular aquarium fish. The Pajama Cardinalfish can grow to be a length of 3 inches. The fish has red eyes and broad, dark, vertical "waistband" that is sprinkled with red spots that leads toward the tail. This fish has low vulnerability. Pajama Cardinalfish circulate throughout much of the West Pacific, from Jave to Fiji and from south of the Ryukyu Islands to the Great...
