Coral reefs may be protected by natural ocean thermostat
02-07-2008 · EurekAlert!Natural processes may prevent oceans from warming beyond a certain point, helping protect some biologically diverse coral reefs from the impacts of climate change. A new study, by scientists at NCAR and the Australian Institute of Marine Science, finds evidence that an ocean "thermostat" is helping regulate sea-surface temperatures.

- Ancient coral reef tells the history of Kenya's soil erosion
04-10-2007 · EurekAlert!
Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

- Waters off Washington state only second place in world where glass sponge reefs found
07-30-2007 · EurekAlert!
University of Washington scientists have discovered large colonies of glass sponges thriving on the seafloor 30 miles off the coast of Washington. The species of glass sponges capable of building reefs were thought extinct for 100 million years until they were found in recent years in protected Canadian waters, the only place in the world they've been observed until now. The discovery in Washington waters extends the range of reef-building glass sponges into open ocean.

- Coral reefs unlikely to survive in acid oceans
12-14-2007 · EurekAlert!
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean's chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution's Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98 percent of present-day reef habitats will be bathed in water too acidic for reef growth.

- Indo-Pacific coral reefs disappearing more rapidly than expected
08-07-2007 · EurekAlert!
Corals in the central and western Pacific ocean are dying faster than previously thought, University of North Carolina at Chapel Hill researchers have found. Nearly 600 square miles of reef have disappeared per year since the late 1960s, twice the rate of rainforest loss.

- Innovative Tagging Technique May Help Researchers Better Protect Fish Stocks
08-07-2007 · Woods Hole Oceanographic Institution (WHOI)
WHOI fish ecologist Simon Thorrold has received a research
grant from the David and Lucile Packard Foundation to use harmless
chemical tags to track the dispersal of the larvae
of coral reef fishes in the western Pacific Ocean. The unique tagging
experiment will help determine if Marine Protected Areas aid in
the recovery of fish stocks.

05-03-2007 · EurekAlert!
A team of Australian, American and French coral reef scientists has achieved a world breakthrough in tracking fish that could revolutionise the sustainable management of coral reefs and help restore threatened fisheries. Working on coral reefs in a marine protected area in Papua New Guinea, the team has pioneered a new way to study fish populations by "tagging" adult fish with a minute trace of a harmless isotope, which they pass on to their offspring.

- Healthy coral reefs hit hard by warmer temperatures
05-07-2007 · EurekAlert!
Coral disease outbreaks have struck the healthiest sections of Australia's Great Barrier Reef, where for the first time researchers have conclusively linked disease severity and ocean temperature. Close living quarters among coral may make it easy for infection to spread, researchers have found.

- World's largest marine protected area created in Pacific Ocean
02-14-2008 · EurekAlert!
The small Pacific Island nation of Kiribati has become a global conservation leader by establishing the world's largest marine protected area -- a California-sized ocean wilderness of pristine coral reefs and rich fish populations threatened by over-fishing and climate change.

Stanford researcher Brendan Roark to talk at AAAS meeting about discovery that deep-water corals off Hawaii are as old as 4,000 years. Coral may hold clues to ocean and climate changes of past centuries, and must be protected from devastation from fishing ships and coral harvesters.
