Ocean Acidification: The Great Barrier Reef

Improved Essays
Geographical processes:
Oceans should have a pH level of around 8.2, However has fallen 0.1 pH. If it continues to drop it will be around 7.8 by 2100. Monitoring the pH levels in oceans is extremely important as it affects the marine eco-system (Kolbert, 2016).

The Great Barrier Reef is one example of the destruction that ocean acidification can make. Acidification along with ocean warming poses greater threats in coral bleaching. Corals need to sustain calcification so that they can use it for coral recovery and repair after physical erosion. AIMS researcher have discovered that CO2 caries across the Great Barrier Reef, however the effects of acidifies seawater will be that the massive corals will lose their structural complexity and lose

As acidification changes the chemistry of the ocean, it reduces the water’s ability to absorb and muffle low frequency sound by 40%, which makes certain parts of the ocean noisier than other parts. Ocean acidification alters the reproduction in some species. Species that have or grow shells or have an exoskeleton of calcium carbonate like prawns, molluscs, gastropods and corals. With animals without protection are most vulnerable to get eaten or attacked by predator, this means that there will be rapid changes throughout the food chain. Furthermore, it affects the marine organisms, biodiversity and fisheries. Scientist noticed that carbon dioxide dissolves immediately in cold water than in warm water. They have also documented that pteropod shells grow more slowly in acidified water, they are extremely important as they are food for fish, whales and bird in the Arctic and Antarctic’ (Kolbert, …show more content…
It is known that acidified waters help with the coral bleaching process and decreases the growth rate by reducing calcification rates. Corals which produce high magnesium-calcite and aragonite, also produces lots of calcium carbonate that makes up the reef structures, which provide homes and protection to a wide range of marine organisms. The acidification also reduces reproduction and recruitment rates within the coral environment. There is concern that ocean acidification will limit and reduce the biodiversity. It is likely that the changes in the species abundances due to the tolerance or intolerance or indirect changes through in competitive interactions will happen in the future (National Research council,

    Page 2 Biological Effects on Marine Life In a biology class, I learned about things such as buffers, acids, and bases. I learned that the more Hydrogen molecules that a substance has makes it more acidic, and the more OH- molecules a substance has makes its concentration more basic. This is relatable to what I have learned in biology class because beneath our seas, some type of acidification is going on because of the hydrogen molecules are in the waters from the excess carbon dioxide that had been released from the atmosphere. When something is too acidic, it does read danger.…

    Seashell Lab What does the different concentration of acid do to shells? Due to earth’s increasing carbon dioxide (CO2) rates scientists have shown that it can make shells , skeletons and corals up to one-third lighter in weight. As the ocean water becomes more acidic it lowers the calcium carbonate available to aquatic animals. ‘Scientists have predicted that the increase in ocean acidification could significantly reduce the ability of these creatures to build their casings, potentially devastating them and causing rippling effects through the ecosystem.’…

    Scientific Validity of “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” Coral reefs are having a problem with pH levels and they are dying some places around the world right now, because of it. This is not only affecting the coral reefs, but the animals that live in them and survive with them. There is a Scientific Study called “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” which discusses the behavior and neurological impairments of coral reef fish due to more CO2 and acidic levels of pH. More CO2 causes lower levels of pH and makes it more acidic and very dangerous for fish. Overall this is a poor scientific article, because it has only one good source…

    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.…

    I believe this is strong evidence of climate change. Modern humans have been around for around 200,000 years (NHM), only a fraction of 50 million, yet the rate at which ocean acidification has occurred has been the quickest ever recorded. In humans, the blood is around a 7.4 on the pH scale, and even the smallest change, such as 0.2, can cause problems like seizures or death (Bennet). If the smallest change can make a difference in a human, a small change in acidity can make an even bigger difference in smaller organisms. These changes can cause major problems with the small organisms themselves, or they can cause the organism to die off.…

    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?,…

    Humans rely on the oceans as a resource for food; seafood is a common addition to people’s diets. However, ocean acidification will negatively impact ocean species such as shellfish as they will be unable to produce tough shells due to decreased carbonate ion concentrations. An example of a food source already impacted is oysters in the Pacific Northwest, where larvae have responded negatively to acidic conditions, leading to a decline in the survival and growth of young larvae (4). This has also threatened a large industry rhar has an overall economic value of US$278 million in 2009 (4). This presents an issue as mussels are a large food source for many sea creatures and could harm the ocean food chain, putting a strain on the seafood industry.…

    The lower the pH, the higher the acidity. Oceans have acidified by 30% from pre-industrial levels, and scientists expect that number will increase to 100% by the end of the century. As acidity increases, animals like scallops and oysters have a hard getting the calcium carbonate they need to build their shells. Their shells become thinner, growth slows down, and death rates rise. Reefs are extremely sensitive to both warming and acidification.…

    Most aquarists that have an irregular pH would rather use a natural means of balancing the pH of salt water because of the beneficial effects on, not only the overall water chemistry, but the non-lethal effects on the waters inhabitants. A very common pH balancer is crushed coral, which is a chemical mixture of solid aragonite. Aragonite is a polymorph of calcium carbonate, and a natural pH buffer. Crushed coral could quite possibly be the solution for reversing ocean acidification, however, like adding a base to the ocean it is economically improbable. When coral dies in the ocean an area of calcium carbonate deposits are all that is left.…

    It is crucial that society begins to take action and take care of the ocean because it makes up 71% of the Earth. For example, acidification, or the reduction in the Ph levels of the ocean as a result of carbon dioxide is affecting the ocean and the marine life alike. Pollution, such as the discharge of fossil fuels from cars, and overfishing are also significant causes of ocean acidification. The carbon dioxide that the ocean absorbs also heats the water, which creates higher sea levels, the melting of polar ice caps and other extreme weather such as intense rainfall and on the opposite side of the spectrum, droughts. Acidification is also harmful to organisms that use calcium carbonate to make shells for protection.…
