The industrial revolution began in the 18th century, which gave rise to an increase in atmospheric carbon dioxide (CO2) levels. CO2 is released into the atmosphere from car engines, and the burning of fossil fuels in factories. About 30% of the CO2 in the atmosphere is absorbed by the oceans (Meinshausen, et al., 2011). CO2 reacts with seawater to form carbonic acid (H2CO3) which then forms bicarbonate (HCO3-) by releasing a Hydrogen ion (H+). CO2 can accumulate in the ocean from cellular respiration, as well as when an organism dies it sinks to the bottom of the ocean floor and releases CO2 with decomposition. The higher the H+ concentration in a liquid the lower the pH of that liquid. Ocean acidification is the phenomenon of CO2 being absorbed by seawater and the water becoming more acidic. The atmospheric level carbon dioxide is expected to rise to as high a 900 ppm by the year 2100 (Meinshausen, et al., 2011).
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 term that describes significant changes to the chemistry of the ocean. It happens when carbon dioxide gas is absorbed by the ocean and reacts with seawater to produce acid. This mechanism is happening in the ocean that over time will affect the coral species.
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.
Ocean acidification is becoming on of the most concerning subjects compared to global climate change. pH is the level of acidity, seven being neutral fourteen being most basic and zero being most acidic. The pH levels in the ocean are dropping and becoming more acidic. This is happening because of increasing carbon dioxide emissions. The ocean is taking in the carbon dioxide from the atmosphere.
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.
Over the past couple of years, no other issue has received more attention in the marine community than ocean acidification. Marine biologists have been constantly working towards solving this issue and are hoping to see improvement’s very soon. Ocean acidification refers to the relentless growth in acidity of the Earth’s oceans. This on-going acidity has attributed to an important element; a constant rise of carbon dioxide levels in the Earth. The number one reason this issue is still happening is because of burning fossil fuels. In addition to burning fossil fuels, it has come to a point where it has enlarged a large amount of carbon dioxide by releasing it into the atmosphere. Chemists have taken this issue into attention that carbon enters the ocean and combines with seawater to fallout acid, which boosts the level of acidity. This process is known as ocean acidification.
Ocean Acidification began over 200 years ago when the industrial revolution came along. This caused carbon dioxide levels to rise.
This threatens coral ecosystems, mussels, clams, and dozens of other species just on the ocean acidification side by weakening their protective barriers and altering the pH of the water. Polar bears, sea turtles, right whales, African elephants, and frogs are just some of the few animals being driven to extinction right now because of climate change. Obviously, these species are not dying off for no reason: the big bad guy is the results of rising levels of c02 due to human’s mass consumption of it for transportation, electricity, and industry. And scientists agree – “99 percent of currently threatened species are at risk from human activities,” says the Center for Biological Diversity, adding that global warming is one of the three main abusers. Ocean acidification is global warming’s “equally evil twin”, as Elizabeth Kolbert writes in her novel The Sixth Extinction. Clearly, human’s c02 waste is causing environmental issues that threaten and eventually extinguish plant and animal
Ocean acidification is the process in which the ocean soaks up carbon dioxide and its pH lowers. At the current point in time, the pH in the ocean has dropped 0.1 pH. ALthough this doesn’t seem like much, since pH is logarithmic, this means that the ocean is 30% more acidic than before. This jump in acidity will literally melt the shells of oysters, and sometimes even fish. What causes ocean acidification is carbon dioxide. Normally, carbon dioxide wouldn’t be that much of a problem as the ocean has a natural buffering system. The carbon dioxide would combine with the water molecules and create a bicarbonate ion then it would gain another H+ molecule and would create a carbonic acid. This acid replaces the much needed carbonate molecules which
The effects of climate change on land are easily visible, with events like droughts and melting polar ice, for example, drawing considerable public attention. But out in the oceans, which cover over 70% of the globe, it seems that climate change effects are, for the most part, out of sight and out of mind. Our oceans contain between 50% and 80% of all the life forms on earth, and losing them would completely change the face of our planet, even if it wasn’t easily visible, at first.
obal Warming is caused by the built up of carbon dioxide and other air pollutions. These absorb sunlight and solar radiation, trapping the heat which causes global temperatures to rise. Ocean Acidification is caused when the ocean absorbs carbon dioxide from the air causing it to be acidic. Scientist believe that the ocean has absorbed about half of the excess carbon dioxide in the past 200 years. This has caused a drop of 0.1 in ph. Since the pH scale is logarithmic, this change represents a thirty percent increase in acidity.
As earth’s carbon dioxide levels are expected to continue to grow in an exponential fashion they will, ultimately, facilitate large shifts in seawater carbonate chemistry (Doney, Fabry, Feely, & Kleypas, 2008). It has been shown that surplus amounts of atmospheric CO2 decreases the pH level in oceans- disrupting the delicate balance of the stable acidity levels that have maintained the rich and varied web of life in today’s seas (Kleypas & Yates, 2009). This phenomenon is referred to as ocean acidification and is predicted to have rapid and devastating consequences to entire marine ecosystems.
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.
