Acidification Of The Oceans : Acidification Essay

The rising carbon dioxide (CO2) from the burning of fossil fuels and other human activities continues to affect our atmosphere, resulting in global warming and climate change. This carbon dioxide is also altering the chemistry of the oceans, causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have drastic consequences on marine ecosystems. Such as altering species composition, disrupting marine food webs and ecosystems and harming fishing, tourism and other human activities connected to the sea.

“Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day” (Ocean Portal, n.d). This number is expected to increase forevermore as atmospheric carbon dioxide levels increase and the effects of Climate Change worsen. At first, the idea of our oceans absorbing carbon dioxide from the atmosphere may sound great, however, scientists have been quick to learn otherwise. High concentrations of carbon dioxide in oceans can have detrimental effects on the ocean chemistry and marine ecosystems (Hardt; Safina, 2008). Marine ecosystems are greatly complex and depend on every marine organism to function properly, any change can put the whole ecosystem at risk. For example, the increase of carbon dioxide in our oceans is responsible for the dissolving of “brittle star” skeletal parts, which has in effect caused food scarcity for many fish, crabs, shrimp, and other starfish (Leu, 2013). Furthermore, these marine ecosystems are very important to humans- being the primary food source for millions around the world and having an economic market worth trillions of dollars (Hardt; Safina, 2008). Part of keeping these ecosystems safe is to understand how they work and how projected changes can harm marine organisms.

Presented in an informal style of writing, “What Is Ocean Exploration and Why Is It Important?” inform its readers about the importance of researching and discovering the unknown ocean. It explains how much work is needed for the documentation of the ocean in varies areas, at the same time it addresses that scientist will be able to better understand the unknown oceans. For example, the time needed to obtain and study the result, as well as answer how the change in atmosphere will cause the ocean to react and affect life. The information obtain will also provide the baseline for scientist, researcher and government agencies to make important and dangerous decisions for the future. Sometime during research amazing things happen and new resources may be revealed. Besides informing about the ocean researching, the article also has a background idea as it is trying to encourage and get its readers interested into joining the field of ocean researching by emphasizing the role the ocean plays and how it will help ensure that ocean resources are well managed for future generations to enjoy.

Ocean Acidification is a process that occurs everyday and majorly affects our planet, but most people don’t even realize it exists. Though it can technically be argued that Ocean Acidification has some benefits for the planet, most of the time the effects of this process are very poor and negatively affect the entire world around us. Human evolution has played a major role in contributing to Ocean Acidification. Whenever humans use energy we release Carbon Dioxide into the atmosphere or also known as CO2. This can be in the form of burning fossil fuels from the ground or the removal of national forest by burning. CO2 is a greenhouse gas, which means whenever we can emit it in large quantities or unnatural amounts it can have negative effects on the atmosphere. These high levels of CO2 in the atmosphere result in climate change and more specifically Ocean Acidification. Ocean Acidification occurs when excess Carbon Dioxide is absorbed into the ocean. When this process takes place it can completely disturb the chemical balances of the water. For example, it can reduce pH levels, Biodiversity, and the abundance of calcifying species.

This increase in oceanic inorganic carbon has offset the seawater carbonate chemistry by causing increasing concentrations of CO2 and bicarbonate, while causing decreasing concentrations of carbonate and pH levels (Dedmer 2013). Rost and colleagues (2008) express that emissions of fossil fuel have caused an immense increase in the levels of atmospheric CO2, which are then deposited into the surface water of oceans. This increase in carbonic acid is in turn decreasing the pH balance, which poses a threat to marine organisms.

I am a water loving science geek teenager, who has dreamed of being a marine biologist since I was a child. My love of water started when I was four years old participating in my first swim lesson at my local YMCA, which I now work at as a lifeguard and swim instructor. My water passion has continued throughout my life advancing through swim lesson to club and high school swimming. One of my proudest moments was swimming with kids twice my age and keeping up the whole swim lesson, which for me was more of a practice. After that, swim lesson extremely tired, but could not wait to go back.

Since the beginning of the industrial revolution, mankind has slowly increased the total greenhouse gas emissions that enter the atmosphere. Over time, this pollution began to add up. Now planet Earth is struggling to maintain its health with the combined forces of global warming and ocean acidification looking to bring demise. From all portions of the world, troubling changes are emerging in the chemistry of our oceans’ waters. The oceans takes in around a quarter of the Carbon Dioxide that mankind releases into the atmosphere every year, so as atmospheric Carbon Dioxide levels rise, so do the

Especially in the last two hundred years, carbon dioxide has increased in the atmosphere. This is happened in effect of the constant burning of fossil fuels and land use change. In the ocean, carbon dioxide reacts with seawater to form carbonic acid.The ocean actually absorbs thirty percent of all of the carbon dioxide emitted in the atmosphere. When

Most of the CO2 that enters the atmosphere dissolves into the ocean, as close to a third of the CO2 produced from human activities since 1800 and approximately half produced by burning fossil fuels are consumed into the ocean (Sabine et al. 2004). Increased CO2 in the atmosphere is one of the main causes of our changing climate change (NOAA, 2011). Global ocean temperatures have risen by 0.74oC (1.3oF) since the late 19th century. With the increasing rate of CO2 and other greenhouse gas emissions have been predicted to rise to approximately 4.0oC (7.2oF) this century (NOAA, 2016). Just the tropical upper oceans alone have warmed more than 0.01oC per year over the past 50 years and the warming rate is still increasing (NOAA, 2010).

increases. When carbon dioxide dissolves at the ocean’s surface it reacts with the water and then

This tragedy is called ocean acidification. Ocean Acidification is the rapid decrease in the pH, (pH is the measure of ocean acidity,) of the Earth's ocean, caused by its intake of carbon dioxide from the atmosphere. This rapid increase of carbon dioxide is directly coming from the large consumption of fossil fuel that humans constantly release into the air for our own selfish reasons. As we increase the level of carbon dioxide that is being released in a short amount of time, we are letting small amounts seeps into the earth's oceans through the continual water cycle. When the carbon dioxide seeps into the oceans, it begins to turn into carbonic acid. In small amounts, carbonic acid is not seriously harmful and is usually part of the ocean

“How acidification threatens ocean from the inside out: Carbon dioxide emissions are making the oceans more acidic, imperiling the growth and reproduction of species from plankton to squid”, by Marah J. Hardt and Carl Safina addresses the dangers of increasing acidity in the ocean caused by carbon dioxide. Hardt, a research scientist and writer, is the founder of Ocean Ink. Safina, an adjunct professor at Stony Brook University, is the founding president of the Blue Ocean Institute.

Since the industrial revolution, anthropogenic inputs of carbon dioxide to the atmosphere have increased dramatically. Concentrations in the atmosphere have risen 40% from 1750 to 2011, reaching record highs of 390.5 ppm (Stocker, et al., 2013). Due to this, the amount of dissolved CO2 in the oceans has also increased causing acidification of the oceans which can have several effects, mainly on calcifying organisms. Climate change has also influenced the stratification of the oceans due to density changing affecting nutrient distribution. So far, although a number of methods have been explored, there have been no solutions that don’t have their own issues.

Carbon dioxide is a greenhouse gas that we exhale in our daily lives. Plants use carbon dioxide to create oxygen that all mammals use. However, carbon dioxide can also change the chemistry of the ocean, this is often referred to as ocean acidification. The excess carbon dissolves into oxygen in the water, producing a chemical called carbonic acid. This acid causes the ocean to become more acidic. In the eighteenth century, the pH was 8.07 which was slightly basic. Currently, the pH is around 8.01 this is about a twenty-five percent increase in acidity. (National geographic) While this slight change may not seem outrageous, it is causing multiple marine life struggles. The acid melts the shells of pteropods causing a low supply of food that would support larger fish.

Oceans cover about 70% of the earth’s surface. For millions of years, the sea has been responsible for absorbing most of the carbon dioxide in the air. In fact, oceans absorb about one-third or 22 million tons a day of carbon dioxide in the atmosphere. On the other hand, as people have further developed their technology, developing cars with the combustion of gasoline, manufacturing goods involving factories and burning coal, additional greenhouse gases have been released. The advancements have come at a price having the oceans absorb more carbon dioxide than customary. In fact, before scientist started seeing ocean acidification as a threat, it was believed that the ocean’s capacity to absorb the carbon dioxide from the atmosphere was limitless. During the start
