Ocean Pollution : The Acidification Of The Ocean

About half of that man-made CO2 has been absorbed by the oceans, increasing the concentration of carbonic acid, which has caused the oceans to become more acidic. Over the past 300 million years, ocean pH has averaged about 8.2. Today, it is around 8.1, a 25% increase in acidity over the past two centuries. That increase is projected to reach 150% by the end of this century, a rate of change not seen in 65 million years. A more acidic ocean inhibits shell growth in marine animals such as corals, crustaceans and mollusks, and disrupts entire food chains all the

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 is affecting our life more than we ever thought it would be able to. When people first think about oceans, they don’t see the diversity of life that is in there or how much we depend on those organisms and the ocean itself. We only see this ginormous body of water, where some feel like it’s not a big deal if anything happens to it. Ocean acidification (as defined by NOAA) is “ongoing decrease in the pH of the Earth’s oceans, cause by the uptake of carbon dioxide from the atmosphere, this then creates an acid”. Each year the ocean absorbs at least 25-30% of all CO2 from human activity. This can be a huge threat to the diversity of the ocean and the benefits it provides to society. The rate continues to go up, more so than anyone would have thought it would and as these continue to raise the risks we are facing could be bigger than we thought and we could soon be facing a mass extinction.

The ocean has became nearly 150% more acidic. Which the ocean has experienced in nearly 20 million years.

As Dr. Stamper discussed, ocean acidification is a major factor that affects the environment. Both of these have had huge effects on the health and vitality of coral reefs. Since the Industrial Revolution, the pH of the ocean has decreased by 30% and this will have ramifications on the health of humans, food supplies and others. Dr. Stamper mentions himself that we are only focusing on calcium molecules in the acidification reactions instead of all the molecules and how they affect the organisms around them. He said changes in the normal calcification can lead to decrease muscle mass and decreased feeding which can harm the vitality of species in the ocean. He suggests gaining more control of our water usage since it generates 3% of our energy produced. In conjunction, he recommends people take personal steps in water conservation and energy conservation by buying energy efficient lights, low-flow toilets or dual-flush toilets, and gaining control of your heating costs by installing a low-energy system.

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

I would have to agree with the writers of this article in so many ways. The writer says that the ocean has absorbed tons of carbon dioxide from the earth’s atmosphere causing ocean acidification. The declining of plankton is causing marine

Ocean Acidification is the process of Carbon Dioxide entering the Ocean causing it to change its chemical structure. This leads to it become more acidic, affecting Marine and other living organisms negatively. The cause of this Global phenomenon are Power Plants who are producing 10 billion tons of CO2 every year, according to Science Daily. However, the impact of acidification does not stop there, organisms with Calcium Carbonate shells including crabs and mollusks have the potential to go extinct due to their shells being dissolved. But, the reality is that this does not just affect animals, humans can also be in great danger as well because of the Food Chain. These small organisms provide for fish which is a stable protein in many third

Ocean Acidification (OA) is a term used to describe significant changes to the chemistry of the ocean.It occurs when carbon dioxide gas (or CO2) is absorbed by the ocean and reacts with seawater to produce acid. Although CO2 gas naturally moves between the atmosphere and the oceans, the increased amounts of CO2 gas emitted into the atmosphere, mainly as a result of human activities (e.g. burning fossil fuels), has been increasing the amount of CO2 absorbed by the ocean, which results in seawater that is more acidic.This is a major problem to humans and marine life, this is a problem because when the carbon dioxide levels rise the wildlife in the ocean

The oceans of the earth are a massive part of the natural cycles that make this planet habitable. They regulate global temperatures, absorb carbon dioxide, provide a home for millions of plants and animals that make up various levels of the food chain, and so much more. They are a resource given for us to use and benefit from, however, it is also a resource that needs to be protected. It is the fountain of life for the planet and drastic changes to the makeup of the oceans could be detrimental to life as we know it. Ocean acidification is a problem which has come to light in the last decade, but is becoming increasingly concerning to many scientists (1). In this essay I will attempt to direct your attention to some of the

The issue on ocean acidification is popularizing but what exactly is ocean acidification? It occurs when carbon dioxide is absorbed in the ocean’s waters from then on a series of chemical reactions take place which lowers the ocean’s water pH, carbonate ion concentration, as well as the saturation states of the calcium carbonate minerals ( “What is Ocean Acidification?”). Since we are addressing the issue on ocean acidification we will touch on the marine creatures that are harmed and will possibly be harmed due to the acidification of the seawater. A background of the chemicals involved as well the beneficial usage of the chemicals will be described in order to address the solution to this environmental problem.

Even though ocean acidification doesn’t get quite as much attention as some things like rising sea levels, or global warming, ocean acidification is still 1 of the most serious effects of greenhouse gas emissions. Nearly a third of the world’s carbon dioxide emissions, or about 22 million tons of CO2, is absorbed by the ocean every day. Scientists say this pollution has fundamentally changed ocean chemistry. Ocean acidification, a consequence of rising anthropogenic CO2 emissions, is poised to change marine ecosystems profoundly by increasing dissolved CO2 and decreasing ocean pH, carbonate ion concentration, and calcium carbonate mineral saturation state worldwide. These conditions hinder growth of calcium carbonate shells and skeletons by

Computer model projections demonstrate that even with optimistic scenarios, an additional reduction in pH of 0.2-0.3 is predicted by the end of the century (Caldeira & Wickett, 2005). While the chemical processes of OA are largely understood, a considerable research gap exists with regard to the biological and socio-economic consequences of these changes (Brandner, Narita, Rehdanz, & Tol, 2014). The urgency of addressing this issue increased significantly following scientist’s discovery of regions identified as “ocean acidification hotspots” where changes in pH are now occurring at an accelerated rate (NOAA PMEL Carbon Group,

The article of “ocean acidification” has been written by Elizabeth Kolbert for the magazine of National Geographic. In this magazine article, the author has expressed grave concerns regarding the increasing problem of acidification of oceans. The author is of the view that the issue of ocean acidification should be taken very seriously as this problem is irreversible and, if it occurs, it cannot be controlled.

The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of
