Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

Corals may be better placed to cope with the gradual acidification of the world´s oceans than previously thought — giving rise to hopes that coral reefs might escape climatic devastation. In new research published in the journal Nature Climate Change, an international scientific team has identified a powerful internal mechanism that could enable some corals and their symbiotic algae to counter the adverse impact of a more acidic ocean. As humans release ever-larger amounts of...

A team of international scientists working in the central Pacific have discovered that coral which has survived heat stress in the past is more likely to survive it in the future. The study, published today in the journal PLoS ONE, paves the way towards an important road map on the impacts of ocean warming, and will help scientists identify the habitats and locations where coral reefs are more likely to adapt to climate change. "We're starting to identify the types of reef environments...

As any comic book lover knows, when superheroes band together the bad guys fall harder. The strength that comes in numbers is greater than the sum of its parts. The same holds true, researchers have recently learned, when different species of crabs (genus Trapezia) and snapping shrimp (Alepheus lottini) in the central Pacific band together to defend their coral homes from hungry seastars. In these frequent conflicts "one-plus-one doesn't always equal two, sometime it is more," explains...

Novel excavation technique attributes prior damage to land clearing and overfishing The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news — humans are still to blame. The good news — relatively simple policy changes can hinder further coral reef decline. Employing a novel excavation...

Anoxia and toxic sulfide are a menace to coral tissue Researchers of the Max Planck Institute for Marine Microbiology along with Australian colleagues, have examined corals from the Great Barrier Reef affected by the Black Band Disease and identified the critical parameters that allow this prevalent disease to cause wide mortality of corals around the world. Corals infected with Black Band show a characteristic appearance of healthy tissue displaced by a dark front, the so called Black...

As corals continue to decline in abundance around the world, researchers are turning their attention to a possible cause that´s almost totally unexplored — viral disease. It appears the corals that form such important parts of marine ecosystems harbor many different viruses — particularly herpes. And although they don´t get runny noses or stomach upset, corals also are home to the adenoviruses and other viral families that can cause human colds and gastrointestinal...

Gulf Oil Spill Seriously Impacted Deep-sea Corals: Study
2012-03-27 07:34:00

Scientists reported on Monday that they have found “compelling evidence” that the Deepwater Horizon oil spill in the Gulf of Mexico has seriously impacted deep-sea corals. "These biological communities in the deep Gulf of Mexico are separated from human activity at the surface by 4,000 feet of water,” she said,” said Helen White, Assistant Professor of Chemistry at Haverford College and lead author of the study. “We would not expect deep-water corals to be...

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
2013-04-20 15:49:21

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...

Foxface Rabbitfish, Siganus vulpinus
2013-02-17 07:58:30

Image Credit: Dr. Wayne Meadows (NOAA)/Wikipedia The foxface rabbitfish is found in coral rich lagoons, and reefs in the coastal water of the Western Pacific. Around the western Philippines, Indonesia, New Guinea, the Great Barrier Reef, New Caledonia, Caroline Islands, and the Marshall Islands. It has also been sighted around Vanuatu, Nauru, Kiribati, and recently Tonga. Adults usually swim in pairs, but the juveniles have been known to form schools. The adult foxface rabbitfish is...

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...

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...
