Coral reefs throughout the world have suffered immensely from global heating due to human-caused climate change. Australia’s Great Barrier Reef — the largest coral reef system in the world — has experienced four mass bleaching events in seven years, leading to die-offs in up to half of its shallow water reefs. A new study has […]
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 […]
The Australian Marine Conservation Society (AMCS) has released video footage showing that the southern portion of the Great Barrier Reef is suffering from deep-sea coral bleaching, reported The Guardian. The footage shows that the bleaching extends at least as far down as 59.1 feet — the deepest reported during this mass bleaching event, a press […]
In the past eight years, the Great Barrier Reef — the largest coral reef in the world, stretching 1,429 miles — has experienced five mass bleaching events, tied by scientists to climate change. Most recently, corals around six islands in Turtle Group National Park, located about 6.2 miles off Australia’s Queensland Coast, have seen extensive […]
Healthy coral reefs are complex ecosystems that serve as the feeding and spawning habitat for thousands of fish, molluscs, crustaceans and many other marine species. Reefs are not only colorful, but full of sounds, and it is this vast array of noises that is the focus of a new study by scientists at the Woods […]
One of the most visible indicators of ocean surface temperature warming due to climate change is the bleaching of coral reefs. Environmental changes like warming waters can cause corals to expel the algae that live on them and provide them with nutrients, turning the corals white. A new study has found that, while most of […]
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 […]
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 […]
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 […]
