Coral Reef Bleaching Essay Example
Coral Reef Bleaching Coral reefs are by far one of the world's most productive and beautiful habitats. They also provide billions of dollars in economic benefits each year globally. There are so many different organisms in these reefs that scientists have yet to finish counting them. Corals are having the toughest time trying to survive because of bleaching occurring in the reef systems. Bleaching is a term used to describe the harming of zooxanthalle algae, which gives corals their color and food source. When corals loose their zooxanthalle algae they appear white. Global warming has been known to be the reason behind coral reef bleaching. Since corals are very sensitive to temperature change an increase or decrease of one degree Celsius can trigger them to bleach. Soon after severe bleaching they often die. When temperatures exceed maximum levels for long enough the relationship between the zooxanthalle algae and the corals breaks down and bleaching results. Rapid temperature changes may be just a tiny fraction that proves to be the first ecological warning of global warming. Coral reefs face yet another threat generated by carbon dioxide pollution. Pollution by humans has directly and indirectly caused the death of many corals. When carbon dioxide mixes in with the ocean, it produces carbonic acid, which corrodes the beautiful structures of coral reefs. Acidic water makes it hard for these corals to survive. As oceans become more and more acidic, coral reef ecosystems could suffer indefinitely. Temperature changes and pollution is just a couple of the many factors that contribute to coral reef bleaching. A great deal of things can be done to help preserve this natural beauty. Such as, long-term monitoring, coral surveys, water testing for salinity, pH(acidity), depth, temperature, and also recording climate data. Another good way to help is to create policies that manage pollution, over fishing, soil erosion, physical damage from

    1. Coral reefs are elaborate networks of crevices, ledges, and holes made up of calcium carbonate; coral polyps are tiny animals that build coral reefs by secreting a crust of limestone around their bodies that accumulate once multiple polyps die. Coral reefs help moderate atmospheric temperatures by removing CO2 from the atmosphere, act as natural barriers that help protect 15% of the world’s coastlines from erosion by battering waves and storms, provide habitats for a variety of marine organisms, produce about one-tenth of the global fish catch, one-fourth of the catch in developing countries, provide jobs and building materials for some of the world’s poorest countries, and support fishing and tourism industries worth billions of dollars each year. Coral bleaching is when a coral becomes stressed and the algae on which it depends for food and color die out, leaving an underlying white or bleached skeleton of calcium carbonate; this occurs because of increased water temperatures and runoff of silt from the land.…

    This sea is predicted as how the oceans of the planet will look like within the next century. The acidification that might happen throughout the oceans of the world is mostly caused by the carbon dioxide emitted from smokestacks and tailpipes. (527) Thirty percent of the carbon dioxide released by man has been soaked in the oceans. Many marine organisms cannot survive in these high carbon dioxide concentrated conditions. The evidence from Castello Aragonese proves that this polluted sea is missing thirty-three percent of marine organisms that live outside the vent system. Another significant organism of the chemistry of the ocean is the coral reef. Coral reefs are essential for the ecosystem of the ocean. Ocean acidification is a threat to their existence. According to Jane Lubchenco, ocean acidification is global warming’s “equally evil twin.” (qtd. in…

    “Some coral species lose their skeletons altogether” (Fine & Tchernov, pg 9, par 4), “and skeletal growth of recent recruits can be disrupted” (Cohen, pg 9, par 4). So the disruption of the skeletal growth can then make the reefs weaker and more vulnerable to damage and destruction. The acidity of the ocean doesn't just effect the skeletal growth of the coral reefs either. “This is damaging many ocean species that use calcium carbonate to form their skeletons and shells. Studies have shown that calcium carbonate formation is disrupted if water becomes too acidic”(Fujita, pg 2, par 8). So not only coral reefs being effected in skeletal growth, but all organisms that have an outer shell or exoskeleton have trouble developing a strong shell as the acid restricts the calcium production. Another effect that climate change brings about is rising sea levels. “The most obvious consequence of sea level rise will be an upward shift in species distributions. Most species are expected to be able to keep pace with predicted rates of sea level rise, with the exception of some slow-growing, longlived species such as many corals” (Knowlton, pg 10, par 1).” However, dramatic ecological changes could result from decreased habitat availability within a…

    The coral reef normally has temperatures between 73 and 84 degrees Fahrenheit. The desert ecosystems temperatures range between 24.95 and 100.4 degrees Fahrenheit. These average temperatures are very different in many ways. Like the desert ecosystems lowest average is 24.95 degrees Fahrenheit and the coral reef ecosystems lowest average is 73 degrees Fahrenheit. Similarities in climate A similarity in climate is that they both have a pretty stable average throughout the day. These are all similarities and differences of the coral reef ecosystem.…

    Warmer ocean temperatures are also now understood to cause coral bleaching. Rising levels of carbon dioxide (greenhouse gas emissions) are also decreasing the pH level of the ocean, known as ocean acidification. Evidence suggests that this will have a profound effect on the entire marine ecosystem.…

    As this has been happening for many years now most species have learnt to adapt to this change but if it does start to increase more some may not be able to live in those conditions anymore. The rise of this chemical reaction causes the ocean to be more acidic which is a huge issue amongst the ecosystems which lie in the oceans. The carbonate ions are a key component within the ocean, these help build structures for sea shells and coral skeletons, when the carbon dioxide increases the carbonate ions become less abundant. This means that animals are then in trouble of losing their homes or shelter from surrounding predators in the ecosystem. The structures of clams, shallow water corals, plankton, sea urchins, oysters and deep sea corals could be ruined from the increase of the carbon dioxide in the atmosphere. Some certain species of fish may lose the ability to detect predators in the more acidic ocean, with all these changes it will affect the entire food web. Ocean acidification has a major impact on the ecosystems within the rocky shores, and the rest of the ocean but with these changes it could put a huge risk on the living species in the rocky…

    Over the last few years there has also been a large rise in climate causing the oceans to heat up. The oceans heating up cause the carbon dioxide in the water to rise causing a bleaching effect on the coral, which is extremely dangerous because it prevents the coral from growing and causes them to calcify. This issue has caused many conservationist to worry about the future of reefs. According to National Geographic this is becoming a large problem because of how long it takes coral to actually mature. "That spells trouble for corals, which often take 15 years to reach sexual maturity and reproduce only once a year" (As Oceans Heat Up, a Race to Save World's Coral Reefs). National Geographic along with other programs have started many conservations and programs to help slow down the dying rate of the reefs. A biological oceanographer at the University of Miami gave this quote to National Geographic, "So a lot of our efforts are to give first aid to buy time until we can fix the problem, like CO2 [levels]. We can make a difference. It's not that hard" (As Oceans Heat Up, A Race to Save World's Coral Reefs). This just shows that with everyone's help we can all change the future of these…

    The food web is one of the quality things about a coral reef; without the shark, its food web would be off balance. Even though coral reefs are located in different areas within the ocean and they are different shapes and sizes, the food web remains the same. Among the different types of coral reefs, fringing reefs or shore reefs are the most common. The Great Barrier Reef is one of the world’s secret treasures; without it the world wouldn’t have the underwater beauty that it holds. Unfortunately, climate change could affect the loss of coral reefs and the ocean wouldn’t be what it is today. Not only can climate change affect the life of a coral reef, but a human’s touch can damage it too. Just think of a coral reef as a house to humans; the humans would want to maintain the reef just like they maintain their houses. With that being said, protect the coral…

    Coral reefs are home to many fishes and plants. Because of global warming, 16% of the world’s coral reefs were wiped out in one year alone (“Global Warming and Coral Reefs”). Ocean temperatures have also risen by 1.3 ° Fahrenheit since the last 19th century (Coral bleaching and ocean acidification are two climate-related impacts to coral reefs). The increasing carbon dioxide levels lead to coral bleaching. This occurs when coral responds to the stress of the temperature warming. This expels the colorful algae that live within most of the coral dies, so the entire ecosystem disappears. Warmer waters are expected to increase the chance of coral diseases such as black band disease, white plague, and white pox. All of the diseases lead to the killing of coral reefs and the entire ecosystem is supports.…

    Coral reefs have been dubbed the “rainforests of the oceans”, because of the rich diversity of life they support, as more than one quarter of all marine animals depend upon coral reefs. Coral reefs are also a source of food and income for millions of people. The coral reef ecosystems benefit humans commercially, recreationally and environmentally. Without them many tourism based industries would collapse, treatments or cures for some illnesses would disappear, and the countless organisms they support would be left without food or shelter. For these reasons and numerous others, it is vital that we protect coral reefs.…
