Univ. of Miami scientists illustrate threat of increased carbon dioxide to coral reproduction A new study led by scientists at the University of Miami Rosenstiel School of Marine and Atmospheric Science suggests that over the next century recruitment of new corals could drop by 73 percent, as rising CO2 levels turn the oceans more acidic. The research findings reveal a new danger to the already threatened Caribbean and Florida reef Elkhorn corals. "Ocean acidification is widely viewed as an...

Researchers at the Hawai"˜i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai"˜i at Mānoa's School of Ocean and Earth Science and Technology have made a remarkable new discovery. When most people envision coral, they typically think of shallow-water reef-building corals found along beaches and tropical nearshore habitats. These "typical" corals are dependent upon photosynthetic algae (also known as...

An exhibit at Washington's Natural History Museum is aimed at helping to draw attention to coral reefs, which face stress, degradation and outright extinction due to human activity. About 800 women ranging from ages three to 101 years old volunteered to take on the project by Australian activists Margaret and Christine Wertheim of the Institute for Figuring. The volunteers crocheted multicolored strands of wool to mimic the curls of coral, anemones and starfish. The exhibit is called...

Projects address concern for acidifying marine ecosystems With increasing levels of carbon dioxide accumulating in the atmosphere and moving into marine systems, the world's oceans are becoming more acidic, scientists have shown. To address the growing concern for acidifying marine systems, the National Science Foundation (NSF) has awarded 21 grants under the Ocean Acidification theme of its Climate Research Investment. The awards are supported and managed by NSF's Office of Polar Programs,...

National Oceanic and Atmospheric Administration (NOAA) experts are concerned that there could be massive coral bleaching in the Caribbean this year--perhaps on par with the bleaching that damaged over 80% of the basin region's coral five years ago, according to a new study. The NOAA Coral Reef Watch (CRW) monitoring system has determined that the above-average temperatures in the area in 2010 mean that there is "strong potential for bleaching in the southern and southeastern Caribbean through...

Healthy reefs with more corals and fish generate predictably greater levels of noise, according to researchers working in Panama. This has important implications for understanding the behaviour of young fish, and provides an exciting new approach for monitoring environmental health by listening to reefs.Contrary to Jacques Cousteau's 'Silent World', coral reefs are surprisingly noisy places, with fish and invertebrates producing clicks and grunts which combine to produce cacophonies of noise....

MOBILE, Ala., Sept. 15 /PRNewswire/ -- A coalition of leading environmental organizations has unveiled plans for a major Gulf restoration project with the launch of 100-1000: Restore Coastal Alabama Partnership (www.100-1000.org). Alabama Coastal Foundation, Mobile Baykeeper, The Nature Conservancy and The Ocean Foundation officially launched the project as a significant first step in restoring the coast of Alabama and struggling coastal economies via a public-private partnership....

A team of researchers from Australian and New Zealand have discovered an ancient, massive coral reef in the Pacific Ocean, making it the southernmost reef discovered to date. The ancient reef, which is an estimated 9,000 years old and well over 20-times larger than any existing modern reef, was discovered near Lord Howe Island in the Tasman Sea, some 370-plus miles east of the Australian mainland, according to an August 31 press release published online at ScienceDaily.com. The team of...

Xestospongia muta, better known as the giant barrel sponge, is now the most dominant life form in the coral reefs of the Caribbean and the Florida Keys, according researchers from the University of North Carolina (UNC) Wilmington. Working at the Aquarius Reef Base near Key Largo, Florida from August 17 through August 26, UNC Wilmington professor of biology and marine biology Dr. Joseph Pawlik and professor of biology and marine biology Dr. Christopher Finelli have been studying the Caribbean...

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...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...

Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...
