Ocean Acidification Research

Improved Essays
Burning of fossil fuels and deforestation are two major factors of human activities that contribute to the increment of carbon dioxide in the atmosphere since the industrial revolution. The carbon dioxide is absorbed into the ocean resulting in a process called ocean acidification. It is a process where the carbon dioxide released dissolves into the ocean changing the chemistry of the ocean and leads to decrease in the pH of the ocean making the ocean more acidic. Ocean acidification is considered to be one of the most significant effects of climate change as 228 studies have been conducted to examine biological responses of marine organisms to ocean acidification and the results revealed that ocean acidification causes decreased in growth, …show more content…
According to National Ocean Service (NOS) (2016), the marine life is affected by increasing carbon dioxide in the ocean as carbonate ions which are an important building block of structures such as sea shells and coral skeletons decreases. Consequently, insufficient carbonate ions present in the ocean can make building and maintaining shells and other calcium carbonate structures more difficult. Other than that, lower pH of the ocean menaces the marine life such as corals, mollusks, and crustaceans as they face a great challenge when their calcium carbonate shells or skeletons dissolve in the acidic ocean. According to Rodolfo-Metalpa et al. (2011), corals, mollusks and other marine life have shown decrease in skeletal growth due to increase in carbon dioxide level in the ocean. Albright, Mason, Miller, and Langdon (2010) conducted an experiment on fertilization, settlement, and postsettlement growth of Acropora palmata to determine whether ocean acidification threatens successful sexual recruitment of reef-building corals. The results suggest that ocean acidification has the potential to impact multiple, sequential early life history stages, thereby severely compromising sexual recruitment and the ability of coral reefs to recover from disturbance. Other than that, coral reefs may destroyed faster than they can be rebuilt. Doney, Fabry, Feely, and Kleypas (2009) found that increase in the carbon fixation rate of some photosynthetic organisms are also caused by ocean acidification. However, photosynthetic algae and seagrasses require carbon dioxide to live so they would somehow benefit from higher carbon dioxide conditions in the

    For years this planet has been undergoing vast changes in its environment, wildlife, and mostly our oceans. The acidifying of our oceans is because of all the Carbon Dioxide that is absorbed by seawater. A chemical reaction that occur which reduces seawater's pH. All of the Carbon Dioxide is being put into our atmosphere by the burning of fossil fuels. Calcium carbonate minerals are the building blocks for the skeletons of shells of many marine organisms. In certain areas where life now congregates in the ocean, the seawater, is supersaturated with calcium carbonate mineral.…

    The acidification of our oceans increases the likelihood of coral reefs to be destroyed or broken down due to erosion. These nearly extinct ecosystems that are either becoming unstable or are being destroyed forces species to find another environment to make their home or to adapt in. The low survival rate of coral reefs under such harsh conditions makes the survival rate of other organisms detrimental as well because it leaves them vulnerable with the reduced amount of living spaces for fish. Leaving fish open to predators, it also has a harmful effects on a fish’s organs. Even though fish do not have shells, they are still affected by the changes that ocean acidification can cause.…

    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.’…

    Ocean Acidification-Effect on Squid Ocean acidification is a direct result of rising atmospheric carbon dioxide CO2 concentration due different type of human activities, such as burning fossil fuels and deforestation (Halpern). The world’s ocean surfaces have gradually become more acidic due to absorption of excess anthropological carbon emissions throughout history. Since the Industrial Revolution during 19th century, the carbon dioxide level has been dramatically increasing. In addition, the CO2 concentration level has reached a constant of 280 ppm during Pre-Industrial and will reach 700ppm by the year of 2060 under the projections (Cooley). Figure 1 shows that as the carbon dioxide levels increase in ocean, the pH level decrease.…

    Well-discussed Marissa. You are correct that the ocean acidification implies to the fundamental changes in the chemical balance or chemistry of the Earth’s oceans due to the increased levels of carbon dioxide in the atmosphere caused by burning of fossil fuels (e.g. coal, fuel oil, and natural gas). Ocean acidification is distinct from global climate change; however, the global threats to ecosystems resulting from ocean acidification are theoretically similar as global warming and also, both are caused by carbon dioxide; therefore, several marine biologists have called ocean acidification as “the other CO2 problem” (Doney et al. ,2009; Jurmain p.475). This rapid increase of the CO2 into the atmosphere is being produced by human activities; and…

    Carbon dioxide emitted into the atmosphere through the burning of fossil fuels by humans dissolves into seawater. This dissolved carbon dioxide lowers the pH of the water; this in turn directly relates to the passage and the Red Reef Crab by stating ..."even a minor environmental stressor, such as a slight change in pH or in water temperature, can cause corals to sicken or die." Because of the depletion of corals, many scavenger species such as the red reef crab may experience a brief population bloom, but once they have all eaten the dead fish, the scavengers die as…

    Marine ecosystems and organisms are more sensitive to temperature change than land ecosystems and organisms. The most vulnerable to temperature change is corals. Corals tend to bleach, or eject their symbiotic algae, at a slight temperature rise. When corals bleach, it slows their growth and makes them more vulnerable to disease, which can lead to a reef die-off (“Sea Temperature Rise”). If corals bleach too often, they are more likely to starve, shrink, and die.…

    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?,…

    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.…

    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.…
