THE BARRIER REEF OFF TAHITI, FRENCH POLYNESIA :THE BARRIER REEF OFF TAHITI, FRENCH POLYNESIA : 14 000 YEARS OF POSTGLACIAL GROWTH14 000 YEARS OF POSTGLACIAL GROWTH
In the course of the Quaternary, sea levels varied significantly under the effect of periods of glaciation (fall in level) and deglaciation (increase). The lowest level was reached during the last glacial maximum around 20 000 years BP, at 120 to 130 m lower than the present figure. Subsequently, melting of the ice caps has favoured a steady rise... view more... (2000-03-09)
Rabbits to the rescue of the reef
While rabbits continue to ravage Australia's native landscapes, rabbit fish may help save large areas of the Great Barrier Reef from destruction. view more (2008-03-19)
While global warming is fatal to many reefs, some corals are able to fight the heat, Cornell researcher reports
While humans can survive large temperature fluctuations, such species as corals are only comfortable within a 12-degree temperature range. And rising global temperatures appear to be threatening their survival, according to Drew Harvell, Cornell professor of ecology and evolutionary biology. view more (2007-03-05)
Massive coral death attributed to earthquake
Scientists have reported what is thought to be one of the world's greatest mass death of corals ever recorded as a result of the earthquake in Aceh, Indonesia on 28 March 2005. view more (2007-04-12)
Stormy Days Ahead for Coral Reefs
The increasing violence of storms under global climate change will have major effects on coral reefs - and has important implications for their future management. view more (2006-11-29)
Illegal destruction of coral reefs worsened impact of tsunami
The illegal mining of corals off the southwest coast of Sri Lanka permitted far more onshore destruction from the 26 December 2004 tsunami than occurred in nearby areas whose coral reefs were intact. view more (2005-08-16)
Valuable coral reefs under siege
Leading coral reef experts are meeting today, 16 December 2004, at the Zoological Society of London to discuss the alarming rates of decline and formulate an action plan to prevent the demise of these important ecosystems. With approximately 20% of coral reefs already destroyed, it is thought that close to 50% may be close to collapse. view more (2004-12-15)
Extinction by asteroid a rarity
In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong. view more (2008-10-07)
Coral reef fish harbor an unexpectedly high biodiversity of parasites
IRD researchers showed that Epinephilus maculates, a fairly abundant species of grouper off New Caledonia, was parasitized by 12 species of microscopic monogenean worms. view more (2007-09-06)
Tiny 'housekeeper' crabs help prevent coral death in South Pacific
Tiny crabs that live in South Pacific coral help to prevent the coral from dying by providing regular cleaning "services" that may be critical to the life of coral reefs around the world, according to scientists from the University of California, Santa Barbara. view more (2006-10-24)
Coral death results from bacteria fed by algae
Bacteria and algae are combining to kill coral —— and human activities are compounding the problem. view more (2006-06-13)
Lionfish decimating tropical fish populations, threaten coral reefs
The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems - a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent. view more (2008-07-21)
Help for climate-stressed corals
Banning or restricting the use of certain types of fishing gear could help the world's coral reefs and their fish populations survive the onslaughts of climate change according to a study by the ARC Centre of Excellence for Coral Reef Studies at James Cook University, the Wildlife Conservation Society, and other groups. view more (2009-06-18)
Coral reefs are increasingly vulnerable to angry oceans
Size and shape may predict the survival of corals around the world when the weather churns the oceans in the years to come, according to a new model that relies on engineering principles. view more (2006-11-27)
Coral reef reveals history of fickle weather in the central Pacific
For more than five decades, archaeologists, geographers, and other researchers studying the Pacific Islands have used a model of late Holocene climate change based largely on other regions of the world. view more (2006-05-17)

Light pollution offers new global measure of coral reef health
We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl. view more (2008-11-25)
CSIRO imagery shows outer Great Barrier Reef at risk from river plumes
A stunning series of satellite imagery of Australia's Great Barrier Reef released by the CSIRO shows for the first time visual confirmation of the theory that sediment plumes travel to the outer reef, and beyond. view more (2007-02-28)
First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands
As part of the international Census of Marine Life (CoML), a team of world renown scientists will embark on an expedition to explore coral reef biodiversity in the largest fully protected marine area in the world-the Northwestern Hawaiian Islands Marine National Monument. view more (2006-10-11)
Investigating coral reefs to help understand past and future climate change
Increasing Earth temperatures and rising sea levels. Both of these are effects of climate change. view more (2007-05-17)
