Ocean Acidification Research Paper
Ocean acidification is the continuous reduction of the ocean’s pH, carbonate ion concentration, and saturation states of biological calcium carbonate minerals. Ocean acidification is caused by the uptake of carbon dioxide from the atmosphere. According to “Ocean Acidification: The
Other CO2 Problem,” after the industrial revolution, carbon dioxide levels in the atmosphere has increased nearly 40%, primarily due to the burning of fossil fuels and deforestation (Doney S. 2009). The increase of carbon dioxide is dangerous because an estimated
30%- 40% of atmospheric carbon dioxide dissolves into the ocean, lakes and rivers ( Feely.
2004). Thus if the atmospheric carbon dioxide concentration increases, so does the concentration of carbon

When carbon dioxide ( CO2) reacts with water ( H20), carbonic acid ( H2CO3) is formed. Carbonic acid, then releases Hydrogen ions (H+), which bonds with other molecules in the surrounding area. Specifically, some of these hydrogen ions (H+) combine with carbonate ions ( CO3-2) and Bicarbonate (HCO3) ions are formed. Thus ocean acidification decreases carbonate ions; This causes a problem for marine ecosystems, because carbonate ions are essential factor to marine life. The acidity of seawater is determined by the amount of hydrogen ions in solution , which is then measured on the pH scale. The higher the concentration of hydrogen ions in a solution, the lower the pH of the solution. As stated in the previous paragraph, carbonic acid ( CO3-2) releases hydrogen ions ( H+) into the solution. If the sea water absorbs more carbon dioxide and then more carbonic acid will be formed as well. Which means the ocean will releases large quantities of hydrogen ions. Thus lowering the pH of the ocean. “ Ocean acidification: A greater threat than climate change or Overfishing,” reports that since the industrial revolution the pH of the ocean has dropped from 8.2 to 8.1. This change in the pH of water over the past 150 years is the greatest seen over the past several million years. ( Burner W. 2008 …show more content…
Also, there are certain species such as photosynthetic algae and sea-grass that could potentially benefit from the increase of carbon dioxide; Since, carbon dioxide is mandatory for the survival of this species just like it is for plants on land . None the less, an excessive amount of carbon dioxide absorbed by the ocean changes the chemistry and affects marine ecosystems. Many researchers have studied ways in which the effects of ocean acidification could be decreased or stopped. The Intergovernmental Panel on Climate Change stated that if carbon dioxide emissions continue to increase, the ocean acidity could rise up to 150% by 2100. We can decrease emissions by burning less fossil fuels such as coal, natural gas, and oil; These fossil fuels are used as energy for different means of transportation and are also used to generate electricity, and to carry out different industrial processes. Therefore, it would be best to explore other transportation alternatives such as walking, jogging, biking and electrical vehicles. Also, it's recommended to replace the incandescent bulbs with CFLs (compact fluorescent lights). CFLs require less energy than the traditional incandescent bulbs, it also gives the same intensity of

    The chemical changes in ocean acidification is known to be caused by an increase in the concentration of carbon dioxide (CO2) in the atmosphere, resulting in the lowering of the pH making water more acidic, an increase in dissolved carbon dioxide (CO2), a reduction in the concentration of carbonate ions and an increase in bicarbonate ions. The oceans are currently taking up about one ton of carbon dioxide (CO2) associated with human activities per year. Almost half of the carbon dioxide (CO2) produced in the past 200 years by burning fossil fuels has been absorbed by the oceans. This has already resulted in a change to ocean chemistry, reducing surface seawater pH by about 0.1 units, which corresponds to an increase of about 30%…

    Over the last decade, there has been an increased focus on the impact of human activities on the planet and studying the potential impacts of ocean acidification (OA). Ocean acidification describes a change in the carbon chemistry of the ocean which has been a steadily emerging global environmental health concern. Oceans cover nearly 70 percent of the planet’s surface and play a crucial role in regulating atmospheric carbon dioxide through physical, chemical, and biological processes (Orr, Fabry, Aumont, Bopp, Doney, Feely, ... & Key, 2005). As a result of anthropogenic emissions from using fossil fuels, cement manufacturing, changes in land use and other human activities, carbon dioxide levels have built up in the atmosphere…

    Have you ever been in the ocean before? Have you ever felt it burning your skin? Ocean acidification is becoming a great problem in our world. Ocean acidification is the ongoing decrease of the oceans pH levels due to lots of CO₂ entering the water from our atmosphere. 30-40% of the carbon dioxide from human activity released into the atmosphere goes into lakes, rivers, and oceans. This is causing the ocean to become more acidic. The ocean's acidity has increased by around 30% since the industrial revolution. This affects all of the oceans. Specifically the Arctic, Antarctic, Pacific, Indian, and Atlantic ocean. In this report will explain what is causing this issue, some effects, and some solutions.…

    Ocean acidification is hurting many sea creatures in the ocean. It is also hurting the world food chain. Ocean acidification is when carbon dioxide (Co2) is released into the ocean and the saltwater consumes the Co2. Many creatures have trouble living and reproducing when the ph level is low. It is hurting the world food chain because many people rely on sea creatures for food and if they are slowly dying, there won't be enough food in the world to hold all these people.…

    This change in the carbon cycle to change the chemistry of the oceans, although carbon dioxide is chemically neutral gas in the atmosphere, is active in the oceans. When carbon dioxide dissolves in seawater, it produces a weak acid known as carbonic acid is an unstable acid leads to increased hydrogen ions. These ions to increase Ocean acidity, as measured by lack of concentration of hydrogen ions also reduce saturation of carbon ions, which are needed to form the shells and…

    What is Ocean Acidification? “Ocean Acidification, is the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide (CO2) by the oceans.” (Britannica). Ocean acidification is largely the result of loading Earth’s atmosphere with large quantities of CO2, produced by vehicles and industrial and agricultural processes. Since the beginning of the Industrial Revolution about 1750, roughly one-third to one-half of the CO2 released into Earth’s atmosphere by human activities has been absorbed by the oceans. During that time period, scientists have estimated, the average pH of seawater declined from 8.19 to 8.05, which corresponds to a 30 percent increase in acidity. (Britannica).…

    The fact of the matter is that the levels of CO2 that this planet we call Earth is expelling is incredible. Like 30 billion tons per year incredible. This rate of change drastically effects everything, including the most popular type of surface we have on Earth, our oceans. Although the oceans are delaying the effects of global warming by taking in heaps of carbon dioxide, this does not mean the oceans go unaffected. This is not a small problem either. As oceans take in more CO2, the more this rids the water of carbonate due to the chemical reactions we have studied and drawn up. The problem with taking these very important ions out of the water is that they are one of the two compounds that calcifiers, very small organisms, need to survive. Calcifiers, which are the base of pretty much every coral reef on the planet, need to make shells which is part of their colonies skeleton. This leaves a decision for calcifiers to make: should I expend more energy capturing the decreasing amount of carbonate ions or just give up. Studies show that most calcifiers do not have it in them to continue while some special cases are not affected or other decide to work harder. This is not the only problem for the calcifiers though. During summer, they have a special breeding session and another study by Selina Ward shows that the amount of fertilization that occurs when the water is acidified is far less to that of normal. The whole problem about these calcifiers though is that they are the long known, under-proclaimer base to coral reefs. Coral reefs are part of everyday living for 25% of all sea creatures. 25%!!! Do you know how much this would affect the whole ocean food chain if coral reefs were all of a sudden gone? According to studies, this is what could happen by 2050. On this rate, calcifiers will become less and less due to the carbon dioxide mixing with the water to make carbonic acid which breaks down into hydrogen gas and bicarbonate ions.…

    Oceans, lakes and rivers absorb 30 to 40% of the carbon dioxide produced by the human population. Ocean acidification has been a rising issue for the last three decades, and oceanographers have been studying the carbon dioxide effects on the ocean throughout that time. It is becoming increasingly problematic because the levels of carbon dioxide being emitted into the environment are greater. In the last 200 years, the ocean has become 30% more acidic because as more carbon dioxide is dissolved into the water, the more acidic the water gets. This is destroying the marine life that has had a stable pH level of ocean water for thousands of years. The oysters have been highly affected by the ocean acidification.…

    Climate change has widespread effects. It doesn't just affect weather and temperature. It will also have lasting effects on the ocean and the ecosystems within it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching, a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg,Donner,pg. 9, par 3). This bleaching can stress the reefs and this can effect important functions of the coral. “Moderate bleaching results in stress that causes reduced growth rates and reproductive output, whereas severe bleaching results in coral death. Bleaching also appears to make corals more vulnerable…
