Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients.
Huge stretches of coral reef around the world are turning a ghostly white this year amid record warm ocean temperatures. On Monday, the U.S. National Oceanic and Atmospheric Administration ...
Hawaii's coral reefs (e.g. French Frigate Shoals) are a major factor in Hawaii's $800 million a year marine tourism and are being affected negatively by coral bleaching and increased sea surface temperatures, which in turn leads to coral reef diseases. The first large-scale coral bleaching occurred in 1996 and in 2004 it was found that the sea ...
The mass bleaching of coral reefs around the world since February 2023 is now the most extensive on record, the National Oceanic and Atmospheric Administration (NOAA) told Reuters this week. A ...
A chief mechanism for widespread reef degradation has been stress-induced coral bleaching caused by unusually high seawater temperature. Bleaching is the disassociation of the coral and the symbiont and/or loss of chlorophyll within the alga, resulting in a precipitous loss in the animal's pigmentation.
The NOAA coral reef authority declared the global bleaching event in April 2024, making it the fourth of its kind since 1998. The previous record from the 2014 to 2017 mass bleaching affected just ...
The last global coral bleaching event happened in 2014 and lasted until 2017. More than 56% of global reef areas saw temperatures that could cause bleaching during that time period.
Coral bleaching turns the coral white, but it does not kill it right away. Depending factors like what type of coral is it, and temperature of the water in that specific area, decide on how long the coral has. Coral bleaching effects in Hawaii are primarily caused by water temperature increases due to climate change. A rise in the water ...
