Ocean Acidification Impacts

Currently there is no saturation level above four in the world. If current trends continue, by 2060, there will be no location above 3.5 and by 2100, no place above 3. The negative trends are extremely concerning as the changing water levels are making the reefs’ survival more unlikely. The energy required for calcification increase, and thus calcification rates decrease. Because of the lack of growth, coral diversity plunges. Over half a million species have spent their life on coral reefs. Coral reefs are intricate exchange bazaars that pass nutrients to various animals. Without the reefs, this exchange would not be possible and the abating of the reefs contributes to the disappearance of the ecosystem as a whole. While ocean acidification is not the only reason for the withering reefs, it is the most detrimental. The effect of ocean acidification extends beyond just the coral reefs. This process affects marine animals’ tightly regulated internal chemistry such as metabolism, enzyme activity, and protein function. Ocean acidification alters the presence of key nutrients such as iron and nitrogen essential to animals. It will also make the ocean noisier (Kolbert 136-141). The implications of ocean acidification are interminable. Human realization is imperative to slow the rate at which ocean saturation is declining. The less carbon emissions released in the air, the less carbon dioxide is absorbed by the ocean which will inadvertently prove beneficial to the coral reefs, but also many other species dependent on the

The ocean is a very delicate ecosystem in which the slightest change of pH or chemical composition will result in devastating results. Between 25 and 40% of anthropogenic carbon emissions have entered the marine area since the industrial age (Sabine et

The purpose of this study was to understand and based on results to support the predictable negative effects of ocean acidification on phytoplankton and projected pH values. However, changes in ocean pH did not negatively impact the productivity of phytoplankton according to the log response ratios, which compared the growth rates at projected years (2000, 2100,

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

While the importance of this information may be readily evident to the scientific community, it becomes much more challenging to communicate to governments and policy makers the relevance of ocean acidity, and why it poses economic risk. This is because the “economic value” of the oceans is not fully understood, and very few studies have

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.

The first organisms that ocean acidification affects are calcifying creatures. These include creatures like oysters, calcareous plankton, clams, sea urchins, and coral. The ocean normally has enough carbonate ions dissolved for calcifying creatures to use to create their shells. Ocean acidification negatively affects the ability for these organisms to build their shells. As carbon dioxide dissolves into the ocean it reacts with the water to form carbonic acid (What is Ocean, 2015). Also, as more carbon dioxide dissolves into the ocean, it reacts with seawater to make H+ ions. These H+ ions compete with calcifying creatures for the carbonate ions. The H+ ions often win making it much more difficult for these shelled creatures to make their shells (Cripps et al., 2014). Creatures like conch shells, oysters, and clams are the most negatively affected. But not all creatures are immediately affected. Some organisms such as crabs and lobsters and crabs actually grow heavier shells to combat the effects of changing pH. This adaptation

Climate change is quickly affecting many social and economic sectors, both directly and indirectly. This is particularly true within the natural habitat sector, as varying impacts on global biodiversity threaten the existence of many species world-wide. While many problems such as warmer temperatures and rising sea levels are attributed to increasing carbon dioxide (CO2), there is one crucial problem that is often overlooked: Ocean acidification. As pH levels in the ocean fluctuate, there are devastating effects on sensitive marine ecosystems and individual species. Increased acidic conditions can pose threats to habitats, such as coral reefs and sea grasses (Guinotte and Fabry 320). These living habitats rely on calcium carbonate to form strong external structures, yet higher pH levels inhibit the organisms’ ability to successfully absorb the compounds needed for this process. Additionally, higher levels of ocean acidification can induce decreases in skeletal-forming compounds, diminishing entire populations of small ocean organisms such as crustaceans and phytoplankton (Doney). Therefore, it can be deduced that the increase of greenhouse gases in the atmosphere cripple the marine wildlife ecosystems, because the addition of greenhouse gases, caused primarily by anthropogenic conditions, are acidifying the ocean and disrupting the bio-chemical compounds that are necessary for many marine species to survive.

“Shellfish growers who live on the West Coast of the U.S. are taking steps to adapt to ocean acidification” (What Can We Do 1). By monitoring the seawater chemistry and adopting new practices, shellfish growers are making the most out of this situation that can be easily resolved.

In the modern industrial era, the levels of Carbon Dioxide produced are much more significant than in years before. Due to Carbon Dioxides involvement in ocean acidification, this is a major issue. Since the beginning of the industrial revolution, the pH of the ocean surface has fallen by 0.1 units. Although this may not seem significant, due to the logarithmic properties of the pH scale, this change signifies about a 30% increase in ocean acidity. If this issue isn’t addressed, there will be dire consequences for both marine organisms, as well as humans. To understand ocean acidification, some chemistry needs to be defined and understood.

Sometimes called “climate change’s equivalently destructive twin”, ocean acidification is becoming more and more noticeable as the seawater’s changing chemistry begins to cause environmental and economical problems. When the Industrial Revolution began around 1760, fossil fuel–powered machines gained an immense amount of accessibility and popularity. Since then, carbon dioxide (CO2) levels in the atmosphere have risen enough to change the pH of the world’s oceans. Given that the ocean absorbs almost half of the CO2 that is released into our atmosphere, ocean acidification is inclining into an even greater problem as fossil fuels become a more common energy source in our society. Higher acid levels can harm wildlife, disrupt the food chain, and negatively impact industries that rely on the ocean for business. Ocean acidification is causing growing dilemmas for both marine ecosystems and ocean-based economies. Although many companies and organizations are attempting to fix this problem, acidification is still threatening to cause increasingly harmful issues for the future.

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 refers to a reduction in the pH of the ocean over an extended period time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere (What Is Ocean Acidification?). It has caused bleaching to the reef, due to the rise of ocean temperatures. If the corals are bleached, there will be less shelter for the marine life living in them and some species of aquatic creatures will go extinct because of it. The biodiversity of the aquatic ecosystem in the coral reef will lessen. To reduce this effect, people need to pay attention to their carbon footprint and try to reduce it, keep the greenhouse gasses out of the atmosphere and in turn, it will make the ocean cooler for the marine

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
