Study Publishes New Predictions For Sea Level Rise

Fossil coral data and temperature records derived from ice-core measurements have been used to place better constraints on future sea level rise, and to test sea level projections.

Gene decides whether coral relative will fuse or fight

When coral colonies meet one another on the reef, they have two options: merge into a single colony or reject each other and aggressively compete for space. Now, a report in the March 19th Current Biology, a Cell Press publication, has found a gene that may help to decide that fate.

New deep-sea coral discovered

Scientists identified seven new species of bamboo coral discovered on a NOAA-funded mission in the deep waters of the Papahānaumokuākea Marine National Monument.

4 years after tsunami, Corals stage comeback

A team of scientists from the New York-based Wildlife Conservation Society (WCS) has reported a rapid recovery of coral reefs in areas of Indonesia, following the tsunami that devastated coastal regions throughout the Indian Ocean four years ago today.

Coral reefs found growing in cold, deep ocean

Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 metres under the surface of the Atlantic. Here the tops of the hills are covered in large coral reefs. NIOZ-researcher Furu Mienis studied the formation of these unknown cold-water relatives of the better-known tropical corals.

Rare Corals Breed Their Way Out of Trouble

Rare corals may be smarter than we thought. Faced with a dire shortage of mates of their own kind, new research suggests they may be able to cross-breed with certain other coral species to breed themselves out of a one-way trip to extinction.

How corals adapt to day and night

Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners.

Research in Puerto Rico on Corals and Global Warming

harminka — Tue, 26 Aug 2008 13:08:12 -0500

For just one late-summer night each year, the shallow waters off the coast of Puerto Rico fill with the pale-pink spawn of elkhorn corals -- the tiny, round packets of the adult corals' eggs and sperm.

New indicator uncovered that can predict coral health

harminka — Sat, 19 Jul 2008 03:00:28 -0500

A new indicator of coral health has been discovered in a community of microscopic single-celled algae called dinoflagellates. The study, released in the July 8th edition of the journal Proceedings of the National Academy of Sciences, reveals that a particular type of these algae renders corals more susceptible to disease.

8-day undersea mission begins experiment to improve coral reef restoration

harminka — Sat, 14 Jun 2008 01:17:33 -0500

Scientists have begun an eight-day mission, in which they are living and working at 60 feet below the sea surface, to determine why some species of coral colonies survive transplanting after a disturbance, such as a storm, while other colonies die. Coral reefs worldwide are suffering from the combined effects of hurricanes, global warming, and increased boat traffic and pollution.

Bikini corals recover from atomic blast

Half a century after the last earth-shattering atomic blast shook the Pacific atoll of Bikini, the corals are flourishing again. Some coral species, however, appear to be locally extinct.

Dissolved organic matter in the water column may influence coral health

harminka — Tue, 04 Mar 2008 13:39:05 -0600

Bacterial communities endemic to healthy corals could change depending on the amount and type of natural and man-made dissolved organic matter in seawater, report researchers from The University of Texas at Austin Marine Science Institute and Mote Marine Laboratory in Sarasota, Florida.
