Coral bleaching

Half the coral in the Northern barrier sea are dead due to coral bleaching. Coral bleaching is “When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white”. Now most people may think nothing of that fact. But the reason the coral died due to turning white is to due to the algae leaving the coral’s tissue. The coral and the algae have a “symbiotic relationship with…

Coral bleaching events endangers the sustainability of major coral reef ecosystems around the world, such as the Great Barrier Reef (GBR), the Florida Keys and the Coral Triangle Area. The loss of symbiotic algae and/or their pigment lead the bleaching of corals [2]. Moreover, the mass bleaching phenomena degrade the valuable ecosystem services of coral reefs, which are home to 25% of all known marine species and provide approximately $375 billion per year in goods and services around the world…

Recently coral bleaching has been regarded as questionable but I do not know what happen by it and what is a coral. A coral is seen as a plant but it is actually animal. It belongs to a sea anemone or a jellyfish family. Corals are classified as reef-building corals or precious corals and it is reef building coral that bleach. Body 1. Why coral reef bleaches and decrease What is a white part of corals? It is a bone. When algae which corals have are lost we can see bones through corals’…

Coral reefs aren't only beautiful, they're also extremely important to our ecosystem. Yet we hardly hear about their benefits, or even the fact that the worst coral bleaching event ever recorded on the Great Barrier Reef started in 2014 and officially lasted until about 6 months ago. Only about 7% of the reef just on the southern side was left unbleached & alive at it's worst point.(ABC) Overall about 12% of the worlds reefs were affected by this massive bleaching event. These recent events have…

another massive bleaching event. This ‘bleaching’ occurs when pollutants, excess sunlight, or unusually hot waters drive coral to to expel symbiotic algae, which are the coral’s main source of food, from their tissue, turning the coral white. This process, while not necessarily beneficial to the coral, will not immediately kill the coral. Instead, the coral could possibly be recovered if the condition of the water improves and if the coral can be recolonized by the algae. However, if the coral…

Sixty genera of coral have a symbiotic relationship with the algae zooxanthellae. Only some deepwater and cold water corals can survive without them. This symbiotic relationship benefits both organisms,the zooxanthellae provides the coral with glycerol, glucose and alanine and the coral provides the zooxanthellae with nitrogen and protection against predators. The degree to which the organisms depend on one another vary between species. The zooxanthellae algae gives the coral a yellow-brown or…

known as Corals. These diverse organisms give quite a show in the shallow clear parts of the ocean. Corals live closely together in groups expressing their bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs…

English explorer and naval officer Captain James Cook ran aground off the coast of Queensland, Australia. The loud noise of wood against stone really questioned him with what he may of hit. Little did he know that he would later discover this amazing coral reef that is the largest reef in the entire world. The reef itself is enormous, nearly 1,500 miles long off the coast of Australia. The irony here is that he did not even mean to make one of the world’s most famous discoveries: the largest…

less animals that live in the trees like birds. Also, they help make more berry bushes so that there is more food. The ecosystem would change dramatically if there were no more grizzly bears. Next, in the Data Nugget about coral bleaching the algae living coral is what makes coral the different…

Coral bleaching is caused by multiple stressors. One stressor is when water temperatures that are warmer than normal. The rise in the water temperatures cause the coral to expel algae that thrive in their tissues. When this happens, the coral will turn white. If the bleaching happens for too long it will cause the coral to die. In 1980, global warming caused 80% of the Indian ocean corals to become bleached, about 20% of them died. If the temperature…
