LANDOVER, MD, Dec. 2, 2011 /PRNewswire/ - Twenty five years ago, on December 4, 1986, Walter Wyatt's plane crashed in the waters of Cay Sal Bank, a remote area between Cuba and The Bahamas. It sank almost immediately. Walter, who now lives in Enterprise, Alabama, spent a night in the ocean fending off sharks, plugging holes in his leaking life vest, and hoping for a merciful end. The Coast Guard located and saved him the next morning and his harrowing experience made many headlines....

Observations at submarine springs found along the coast of Mexico's Yucatan Peninsula are giving scientists a preview of the possible fate of coral reef ecosystems in response to ocean acidification. The naturally low pH (a measure of acidity) in the water around the springs creates conditions similar to those that will result from the widespread acidification of surface waters that scientists expect to occur as the oceans absorb increasing amounts of carbon dioxide from the atmosphere....

Leaders Urged To Curb Climate Vulnerability
2011-11-28 05:54:49

Representatives of the world´s governments meeting in Durban this week have been advised by scientists that urgent action is needed to reduce the vulnerability of communities worldwide likely to be worst affected by the impacts of climate change. In a new scientific paper and book, leading marine researchers Dr Josh Cinner of the ARC Centre of Excellence for Coral Reef Studies (CoECRS) and James Cook University, and Tim McClanahan of the Wildlife Conservation Society (WCS) propose a...

2011-11-24 04:05:36

The elusive culprits that are killing countless coral reefs around the world can now be nabbed with technology normally used to diagnose human diseases, marine researchers say. Coral researchers and reef managers will be able to identify coral infections using a new method that allows them to classify specific diseases based on the presence of microbes. This could lead to more effective action to reduce the impact of disease on the world´s imperiled coral reefs. “Current...

Corals Can Sense What's Coming
2011-11-19 04:42:31

Australian scientists have thrown new light on the mechanism behind the mass death of corals worldwide as the Earth´s climate warms. Coral bleaching, one of the most devastating events affecting coral reefs around the planet, is triggered by rising water temperatures. It occurs when the corals and their symbiotic algae become heat-stressed, and the algae which feed the corals either die or are expelled by the coral. There have been seven major bleaching events globally in the past...

Can fish save coral reefs from dying? UC Santa Barbara researchers have found one case where fish have helped coral reefs to recover from cyclones and predators. Coral reefs worldwide are increasingly disturbed by environmental events that are causing their decline, yet some coral reefs recover. UCSB researchers have discovered that the health of coral reefs in the South Pacific island of Moorea, in French Polynesia, may be due to protection by parrotfish and surgeonfish that eat algae,...

Smithsonian scientists and colleagues conducted the first DNA barcoding survey of crustaceans living on samples of dead coral taken from the Indian, Pacific and Caribbean oceans. The results suggest that the diversity of organisms living on the world's coral reefs is seriously underestimated. The team's research "The Diversity of Coral Reefs: What Are We Missing?" was published in October in the journal PLoS ONE. At depths of 26 to 39 feet, the scientists collected dead coral from five...

A team of researchers from the Hawai'i Institute of Marine Biology (HIMB) have developed an interactive global map of corals and zooxanthellae as part of a hybrid web application titled GeoSymbio. This application provides global-scale biological and ecosystem information on symbiotic zooxanthellae called Symbiodinium which are uni-cellular, photosynthetic dinoflagellates that live inside the cells of other marine organisms like anemones, jellyfish, and corals. Symbiodinium are responsible...

Hawaiian Coral Reefs Valued At $33.5 Billion
2011-10-22 04:55:23

A National Oceanic and Atmospheric Administration (NOAA) survey of U.S. residents has discovered that Americans estimate the value of Hawaii's coral reefs at $33.57 billion per year, the scientific agency reported on Friday. According to an NOAA press release, the organization conducted a "scientifically developed national Internet survey of more than 3,100 households" from throughout the entire country, not just the state of Hawaii or the coastal area, from June through October 2009....

2011-10-18 08:46:40

Scientists studying coral reefs in and around the South Pacific have found that some seaweed can cause coral bleaching and suppress photosynthesis by emitting anti-coral chemicals. As part of their study, researchers have identified and mapped the chemical structure of molecules used by certain types of marine seaweed that kill or inhibit growth of reef-building coral. Chemicals found on the surfaces of several species of seaweed have been shown to harm coral, suggesting that competition...

Crown Of Thorns Starfish, Acanthaster planci
2013-11-11 10:54:41

The crown-of-thorns starfish (Acanthaster planci) is a species of starfish that is classified within the Acanthasteridae family. This species has a large range that extends from the Red Sea to the African coasts in the east and from the Indian Ocean to the western coasts of Central America. It prefers a habitat in coral reefs, which can be harmed if population numbers are too high. Damage occurs when filamentous algae covers bare skeletons of coral and the starfish move in to feed, stripping...

Coral Reef

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Knotted Fan Coral, (Melithaea ochracea), is a species of colonial soft coral that is found in tree-like fans on shallow reefs in the South China Sea between Taiwan and Indonesia, including Singapore and Malaysia. In Taiwan, it is the most widespread coral in its family Gorgonacea. It is found on the higher parts of reef fronts where its numerous small polyps can feed at water flow rates varying from 1.6 to 16 inches per second. This species usually grow to about 8 inches in length, with...

Leaf Plate Montipora, (Montipora capricornis), also known as Vase Coral, Cap Coral, or simply Montipora, is a species of stony coral found in the Indian and Pacific oceans. It is also found in reefs in the Red Sea. It usually inhabits the top half of the reef where photosynthesis can occur. It branches out from the foundation into an area with adequate sunlight. This species forms flat, plating colonies. The colonies expand by adding to their foundations and further spreading out....

Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...
