The planet is currently experiencing its fourth global coral bleaching event on record, affecting most of the Great Barrier Reef (GBR). It is the second mass bleaching in the past decade, NOAA scientists said in a press release. Across the Pacific, Atlantic and Indian Ocean basins, heat stress at levels high enough to cause bleaching […]
Quick Key Facts What Are ‘Coral Reefs’? Coral reefs consist of hundreds of thousands of coral polyps — marine animal invertebrates with hard calcium carbonate exoskeletons. Different species grow to form a variety of measurements and shapes — from the size of a pinhead to as large as a foot in diameter. Coral colonies are […]
Parts of an oil spill first detected near the island nation of Trinidad and Tobago on February 7 are drifting into the Caribbean Sea, putting the country’s coral reefs, as well as other nations, at risk. The spill was determined to have been caused by an overturned barge being pulled by a tugboat called Solo […]
A new study led by researchers at Australia’s University of Queensland (UQ) has found that the planet has more coral reef area than previously believed. Scientists have identified 134,364 square miles of shallow coral reefs at depths of up to 65.6 to 98.4 feet deep, according to Dr. Mitchell Lyons of the School of the […]
While scientists have known that pollutants from human activities like agriculture, plastic production and coastal development threaten corals, a new study is the first to find pollutants tied to burning fossil fuels embedded in corals. Researchers from the Instituto de Acuicultura de Torre de la Sal collected samples from the coral species Cladocora caespitosa of […]
Marine heat waves (MHWs) are prolonged periods of ocean warming that can significantly affect coral reefs, fish, kelp forests and other marine life. A new study led by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has found that MHWs are changing the communities of microorganisms that make up the foundation of the oceanic food […]
The National Oceanic and Atmospheric Administration’s (NOAA) Coral Reef Watch has added three new alert levels to track potential risks to coral reefs and other marine life following the hottest year on record. Previously, Coral Reef Watch’s Bleaching Alert Area product stopped at a Bleaching Alert Level 2, which warned of a “risk of reef-wide […]
For the first time, scientists have succeeded in mapping the largest deep-sea coral reef in the world, which runs hundreds of miles off the Atlantic coast of the United States. The massive 6.4-million-acre reef is bigger than the state of Vermont, a press release from the National Oceanic and Atmospheric Administration (NOAA) said. “It’s eye-opening […]
Following what is expected to be the warmest year on record, next year could bring massive coral bleaching events that disrupt marine ecosystems. Ove Hoegh-Guldberg, a marine studies professor at the University of Queensland, Australia, is predicting that coral reefs will experience dramatic bleaching. Hoegh-Guldberg and colleagues shared their predictions in a “Perspectives” piece for […]
