Mining to blame for islands to sink beneath waves
Two small islands in South Asia’s first marine biosphere reserve, in the Gulf of Mannar, between India and Sri Lanka, did sink into the sea primarily as a result of coral reef mining, experts said. The corals were mined for use as a binding material in the construction industry, as they were rich in calcium carbonate.
Loving the Chambered Nautilus to Death
It is a living fossil whose ancestors go back a half billion years, to the early days of complex life on the planet, when the land was barren and the seas were warm. Nautilus lives on the slopes of deep coral reefs in the warm southwestern Pacific, but scientists say humans are loving the chambered nautilus to death, throwing its very existence into danger.
Hawaii’s coral reef ecosystems worth $33.57 billion per year
A peer-reviewed study commissioned by NOAA shows the American people assign an estimated total economic value of $33.57 billion for the coral reefs of the main Hawaiian Islands.
Study Uncovers a Predictable Sequence Toward Coral Reef Collapse
Using data from coral reef systems across the western Indian Ocean, researchers identified how overfishing creates a series of at least eight big changes on reefs that precipitate a final collapse. This information can help assessing the health of a reef and tell when to restrict fishing in order to avoid a collapse of the ecosystem and fishery.
Sea Levels Much Less Stable Than Earlier Believed
New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, new coral dating method suggests.
Fears in Miami That Port Expansion Will Destroy Reefs
As Miami prepares to dredge its port to accommodate supersize freighters, environmentalists are making a last-ditch effort to protect threatened coral reefs and acres of sea grass that they say would be destroyed by the expansion.
Haitian Divers Hope to Aid Ailing Reef
Environmental degradation is rife in Haiti, deforestation, erosion, pollution, and for the most part it is hard to miss. But for decades the country’s marine environment has suffered unseen. Its extensive coral reef system, an attraction to foreign scuba divers in the 1970s and ’80s, has largely died off, partly from sedimentation and climate change, but mostly from overfishing.
Cakaulevu Reef, Fiji
Also called the Great Sea Reef, Cakaulevu shines turquoise through clear, shallow waters. It is the third longest continuous barrier reef in the world, behind the Great Barrier Reef in Australia and the Mesoamerica Reef off Central America.
Worldwide Map Identifies Important Coral Reefs Exposed to Stress
The world’s coral reefs face a multitude of threats, from rising ocean temperatures to overfishing. A new map aimed at aiding coral conservation has been developed that points out the reefs that are most and least at risk.
