METHODS
Bleaching occurrences have happened before the 1980s; however detailed information could not be gathered due to lack of reporting (Berkelmans, De’ath and Kininmonth). In 1911, the first bleaching event was reported at Bird Key Reef in the Florida Keys, in which unfamiliar warm weathers caused “injury” upon the corals and the death of many fishes (Berkelmans, De’ath and Kininmonth). In 1998, the worst bleaching event was recorded. In some parts of the world, live corals were completely harmed (Coghlan).
Although bleaching can be found in animals, it is most notable in corals. These species have a symbiotic relationship with the yellow-brown colored zooxanthellae from the genus Symbiodinium (Douglas ). Figure 3 shows the symbiotic relationship of the algae with a coral (Wadlow ). All species affected by bleaching have undergone mortality in massive numbers. Corals that are bleached usually reflect a white color, which is the calcium carbonate of the underlying skeleton (Douglas ). During coral bleaching, corals can usually determine the amount of zooxanthellae they want to lose. Figure 7 illustrates the process of coral bleaching (Outlook for the reef). However, the more stress upon a coral, the more zooxanthellae it will release than it has to. This causes the corals to lose their beautiful colors and photosynthetic pigments (Hauter and Hauter). The white-colored corals, which can easily be seen, are likely to have a reduced algal density of about 70 to >90% (Douglas ). In Figure 4, the bleached corals are noticeably seen due to their chalk white color (Explore The Great Barrier Reef With Your Child).
There is no exact explanation for coral bleaching. However, many drivers are considered to be associated to the bleach...

...ne to save them. Many will say it’s too late while others will say it is just the beginning. Coral Reefs are the heart of the ocean and due to careless human behavior, sea levels are rising. Ocean temperatures increase causing coral bleaching. This in turn will lead to stronger hurricanes, the washing out of sea beds and mangroves, greater flooding, and destruction of the fishing community. Although scientists have a very detailed idea on what the results from degradation of coral reefs could be, it can be hypothesized that this understanding is being underestimated and no one is prepared for the true outcome of coral bleaching. Many are acting now, but it is necessary to attack the situation more aggressively and faster. Only time could tell on the severity of the situation that lies ahead; however, will the human population allow coral bleaching to reach its peak?

Coral Reefs And Bleaching Phenomenon Essay - Imagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimates. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we will find an equally dynamic environment in the depths of our world’s coral reefs....   [tags: essays research papers fc]

Coral Bleaching: Potential Mechanisms and Observed Adaptations Essay - Coral Bleaching: Potential Mechanisms and Observed Adaptations Coral reefs are the most biologically diverse marine ecosystems. Driving this diversity are cnidarian corals which are obligate mutualistic symbioses between coral animals and dinoflagellate algae of the genus symbiodinium. These algae are commonly called zooxanthellae. This symbiosis between heterotrophic hosts and photosynthetic symbionts allows coral to thrive in nutrient poor seas and deposit calcium carbonate to build reefs (Toller et al....   [tags: Sea Coral Corals Ecosystem Papers]

Essay on Coral Bleaching - Coral Bleaching Coral reefs are the most biodiverse ecosystem on the planet. There are more than 25,000 known species of organisms and countless others that have yet to be identified (Helvarg, 2000). Reefs thrive on the shallow edge of tropical seas, most often on the eastern edge of continents along warm water currents that brush the coasts. Reefs cannot live in cold waters and are limited by ocean depth and available sunlight. Coral is the foundation of the reef community, providing a three-dimensional structure where thousands of species of vertebrates and invertebrates live and feed....   [tags: Papers] 1035 words

Essay on Bleaching Away the Beauty of Coral Reefs - Pretend you are about to go scuba diving in the ocean. You jump in the water and begin to sink down. As you start surveying the coral reefs around you, something catches your eye. The coral has turned white, and no longer moves with life. This whiteness seems to have spread over a large area of the reef. You no longer see the colorful branches swaying in the current, or the schools of tropical fish swimming through the leaves. This death-ridden reef will never have the same life it once had. This phenomenon is known as coral reef bleaching....   [tags: essays research papers fc]

Coral Bleaching Essay - Coral Bleaching Abstract Coral reefs have been called the rainforests of the ocean and are one of the most diverse and important ecosystems on the planet. This paper will explore how global warming has effected these fragile ecosystems. It will focus on the impact of increasing ocean temperatures on coral reefs. Coral Reefs Coral reefs exist globally from 30N to 30S latitude and have existed in some form on Earth for over 200 million years. Over 2500 species of coral have been identified 1000 of which are reef building hard coral....   [tags: Geology]

Coral Reef Destruction Essay - Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse....   [tags: Enviroment, Marine Species]

Essay on Adapting to Our Environment or Harming It? - Adapting to Our Environment or Harming It. I went to do my Thanksgiving shopping on Monday. I figured that if I bought the turkey, turkey stuffing, and pumpkin pie at the beginning of the week, I would avoid the long lines that build up in supermarkets the day before Thanksgiving, while not having to freeze and unfreeze the turkey. I was in aisle 4, trying to decide whether my family would prefer microwaveable Stove Top stuffing or the kind you actually insert into the turkey’s insides when I remembered that I also had to get canned cranberry sauce… my favorite....   [tags: Comparison Compare Comparative Essays] 976 words

Coral Reefs Essay - Coral reefs have been undergoing global degradation due to increasing natural and anthropogenic impacts for at least the last half-century. The intensity and frequency of stressors, including global climate change, have rapidly increased in number over recent years (Hughes & Connell 1999; Hoegh-Guldberg et al. 2007; Pandolfi et al. 2011). Frequent disturbances such as hurricanes/cyclones, predation outbreaks, diseases and mass bleaching events eat-away at the percent of living coral cover and without recovery, the available space is colonized by sponges, soft corals, and macroalgae....   [tags: Environment, Global Degradation] 1225 words

Anthropogenic Effects on Coral Reefs Essay - Abstract: Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people....   [tags: Unprecedented Stresses to Coral Reefs]
