Coral Bleaching

Improved Essays
Introduction Coral reef ecosystems are arguably one of the most biologically diverse ecosystems on Earth. (Spalding 2001) Because of the marine life that swarms these areas, the reefs are comparable to those of tropical rainforests. (Spalding 2001) Additionally they play a critical role in the success of coastal communities, providing protection from storms, and drives tourism to these areas. However, due to unfortunate changes that inundates the coral reef ecosystems from increases in human population, overfishing, and tremendous rises in pollutant productions that is creating devastating impacts to all organisms and areas involved. (Spalding 2001) Aside from the aforementioned issues, a rapid increase in climate changes through human activities …show more content…
(Spalding 2001) This thermal stress response known as coral bleaching occurs and has been on a steady rise. (Brown 1997; Spalding 2001) Amongst the reefs that suffer such thermal distress are those that are found in the Caribbean- which only makes up less than 8% of the world’s reef systems. (Spalding 2001) A vast majority of reefs scattered throughout the Caribbean, even those that are protected, have undergone additional stress aside from that of human activities. (Spalding 2001) Such stresses are diseases, increases in stronger hurricane formations, as well as El Niño events that may attribute to why reefs have seen limited developments. (Spalding …show more content…
(Wilkinson, Linden and Cesar 1999) Although the formation of El Niño Southern Oscillations are secluded to just the Pacific, the effects are widespread with major global impacts on coral reef systems- most notably in the tropical Indian Ocean where storms are likely to develop. (Wilkinson, Linden and Cesar 1999) From the end of 1997 into the latter part of 1998, sea surface temperatures rose in many tropical areas where coral reefs are found 2º -3º C above normal. (Wilkinson, Linden and Cesar 1999) Much of the 1997-98 in this region led to mass mortality, where upwards of 90% of the corals died in a span of several hundred kilometers. (Spalding

    Two reasons why coral reefs are being threatened worldwide are because of tourists, who cause sewage to pollute the ocean and give nutrients to algae, step on corals, and destroy coral reefs with their boat anchors; overfishing causes the mass killing of sea urchins, which feed on algae, thus algae takes over the coral reefs and stunts their growth. B. The process of coral bleaching is when ocean temperatures become too warm, and the algae discharged from the coral causes the coral to begin a stress condition which turns them white; they are no longer the vibrant colors they used to be. When coral reefs lose their good health, organisms cannot live in/around them anymore, and the babies and eggs are exposed to predators, throwing off the aquatic ecosystem. C. 2 ways in which coral reefs can be protected from future destruction are by reducing the use of pesticides and fertilizers which enter the ocean through runoff, and by regulating overfishing with laws that set safe catching limits and controls on…

    Growing up in the Florida Keys, I have been surrounded by the ocean my entire life and have personally witnessed it gradually get destroyed over the years. Because of tourism playing a huge role in the Florida keys, our beaches and oceans are left polluted and leaving our reefs to extinction. Not only in the Keys, but throughout Florida our waters are heavily polluted by the great amount of tourism in our state. In the Florida Keys and the Caribbean, there has been a vast decline in staghorn and elkhorn corals leaving the reefs scattered since the 70’s. As I continued to observe and research this topic, I noticed that humans overlook the effects that they cause and focus on the benefits they receive.…

    “We're seeing areas that have seen high temperatures for two to three years in a row. There's no time for corals to recover.” (Weisberger). This is a direct result of global warming. If there is not a drop in the temperature, there is a great chance that the coral will never recover and it will be lost forever.…

    Between 1800 and 1994, the oceans had absorbed around 48 percent of the total amount of carbon dioxide from burning fossil fuels (IPCC, 2014). Therefore, the amount of carbon dioxide absorbed by the ocean would have increased considerably since then, and with the increased production of carbonic acid which releases bicarbonate and hydrogen ions, the amount of carbonate ions which are necessary in the creation of coral shells and skeletons decrease significantly. (Australian Government, n.d.) Therefore, more acidic seawater impacts coral significantly, dissolving their shells and skeletons, and hindering their ability to absorb calcium carbonate. Ocean acidification not only impacts coral and the animals that rely on coral as their main food source, but the animals that make calcium carbonate shells such as snails and clams (How does climate change affect the reefs?,…

    Topic B: Ocean acidification and coral reefs Introduction • Ocean acidification is a reduction in the pH of the water in the ocean as a result of increased carbon dioxide uptake in the ocean due to humans burning fossil fuels at such a high rate. • Unless drastic changes are made in regards to CO2 emissions, the rate of ocean acidification is projected to significantly increase over the next century. It is currently estimated that without any changes the pH of the oceans will be 7.8 by 2100 ( ). • Climate change and its negative impacts on… • List all points that will be discussed PARAGRAPH 1 - Ocean acidifications potential to affect coral (focus on individual coral colony) Ocean acidification alters a range of marine ecosystems by damaging foundation organisms, such as living corals.…

    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 dark brown colour.…

    The article “Forecasted Coral Reef Decline in Marine Biodiversity Hotspots under Climate Change” examines the suitability of habitats for coral reef development and growth concerning mainly the factor of thermal tolerance. Coral reefs are home to many species and these habitats are key for maintaining biodiversity, yet under climate change this highly diverse system is very vulnerable, especially to changing sea surface temperatures. A slight increase in sea surface temperature can lead to mass bleaching events in corals which may lead to reduced survivorship of the corals and their associated species. One reason that only a slight increase is needed to induce bleaching events is that reefs tend to live near the top of their thermal tolerance…

    Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…

    The article, “Losers and winners in coral reefs acclimatized to elevated carbon dioxide concentrations” by Katharina Fabricus is about how the acidification of the ocean is affecting marine organisms. Acidification is a chain reaction of what happens when the CO2 in the atmosphere is high. Higher CO2 in the atmosphere leads to higher CO2 levels in oceans, when the CO2 dissolves in the seawater it causes carbonic acid to form, and more carbonic acid leads to lower levels of the waters pH, resulting in harm to the aquatic life that inhabits the waters. This experiment, unlike others, focuses on the long-term effects that ocean acidification will have on the coral reefs. The study took place near cool volcanic seeps near the waters of Papua New Guinea on three tropical coral reefs that housed numerous species and organisms.…

    Coral reefs are one of the most diverse and valuable ecosystems on earth. According to the National Oceanic and Atmospheric Administration, coral reefs support more species per unit area than any other marine environment, making them the equivalent of an aquatic rain forest (Kitch and Edwards). Occupying a mere one percent of the seafaring environment, coral reefs are home to more than one quarter of all known marine species. This translates to approximately four thousand species of fish, eight-hundred species of hard corals. and hundreds of other unclassified marine organisms (Fast Facts).…
