The bear on the California state flag is the extinct California Grizzly bear, the bear's name was Monarch and died in 1911. The California grizzly bear went extinct in 1924. And on the topic of extinction humans are causing the sixth mass extinction. The more co2 we release the acidic the ocean becomes through a process called ocean acidification where ocean water becomes carbonic acid.…
elsewhere is absorbed by our oceans. Ocean acidification is caused by just that, the quarter of carbon dioxide that still remains from our atmosphere being taken in by the ocean’s surface layer. When carbon dioxide that hits the ocean’s surface layer combines with seawater, some of the carbon dioxide reacts with the water to from carbonic acid. Carbonic acid separates into hydrogen ions and bicarbonate ions. Then, hydrogen ions combines with carbonate ions forming more bicarbonate ions which makes seawater more acidic.…
Ocean Acidification-Effect on Squid Ocean acidification is a direct result of rising atmospheric carbon dioxide CO2 concentration due different type of human activities, such as burning fossil fuels and deforestation (Halpern). The world’s ocean surfaces have gradually become more acidic due to absorption of excess anthropological carbon emissions throughout history. Since the Industrial Revolution during 19th century, the carbon dioxide level has been dramatically increasing. In addition, the CO2 concentration level has reached a constant of 280 ppm during Pre-Industrial and will reach 700ppm by the year of 2060 under the projections (Cooley). Figure 1 shows that as the carbon dioxide levels increase in ocean, the pH level decrease.…
Well-discussed Marissa. You are correct that the ocean acidification implies to the fundamental changes in the chemical balance or chemistry of the Earth’s oceans due to the increased levels of carbon dioxide in the atmosphere caused by burning of fossil fuels (e.g. coal, fuel oil, and natural gas). Ocean acidification is distinct from global climate change; however, the global threats to ecosystems resulting from ocean acidification are theoretically similar as global warming and also, both are caused by carbon dioxide; therefore, several marine biologists have called ocean acidification as “the other CO2 problem” (Doney et al. ,2009; Jurmain p.475). This rapid increase of the CO2 into the atmosphere is being produced by human activities; and…
Introduction The contamination of large bodies of water is becoming a greater problem across the world due to our rapidly increasing population. People commonly pollute these areas with their release of waste products and trash, and these contaminants can spread from small streams or lakes to oceans and complete ecosystems. The pollutants that are released into the water sources are often inorganic substances, and the dissolved forms of these compounds can become ionic cations and anions. An increase in specific cations, like the positive ion H+ can be especially detrimental to bodies of water due to it’s a contribution towards ocean acidification.…
The article “Ocean Acidification is Bad, and It’s Getting Worse,” was written by Pierce Nahigyan. Nahigyan is the Editor-in-Chief at Planet Experts, he has a degree in B.A in Sociology and History from Northwestern University. Upon reading some of his other articles he has written it is clear that Nahigyan is an excellent writer but has a hard time staying unbiased. While most of his research has scientific backing, Nahigyan has habit of overstating the facts that back his claims. I believe Nahigyan’s biggest issue comes from his passion for what he writes about, most the articles I have read by him seem to be focused on climate change and other political issues.…
Are future carbon dioxide levels going to affect the ocean’s fish population? The future effects of carbon dioxide and climate change cannot be certain, however, Rachel Sullivan argues otherwise. In a recent ABC Science article (2016) the author, Rachel Sullivan, references a study in the journal Biology Letters (Connel, Gillanders, Nagelkerken, Russel, 2015), to draw a conclusion that ocean acidification will negatively affect the soundscape that fish larvae rely on to navigate through the ocean. Rachel Sullivan uses a captivating title and misleading photo, a recently popular topic such as the effects of climate change, while omitting key study information to ultimately capture the reader. Although she used quotes from the study, Sullivan…
Ocean acidification can be defined as the change in ocean chemistry driven by the oceanic uptake of chemical inputs to the atmosphere, including carbon, nitrogen, and sulfur compounds (Guinotte and Fabry, p.320). Today, the overwhelming cause of ocean acidification is anthropogenic atmospheric carbon dioxide. Over the past two-hundred years, the rapid increase in anthropogenic atmospheric carbon dioxide has directly led to decreasing ocean pH through air-sea gas exchange, driven by the land-use changes such as, the burning of fossil fuels, deforestation, industrialization, and cement production (Guinotte and Fabry, p.320). The problem with the change in pH is that since the industrial revolution, the pH of surface oceans has dropped 0.1 pH…
Ocean acidification is a process in which Carbon Dioxide (CO2) is absorbed into the ocean causing an imbalance in the seawater’s pH. Based on these changes, organisms are affected adversely causing various biological impacts of different degrees for each organism. This research paper discusses the effects of ocean acidification on the environment and the surrounding organisms. It will discuss the impacts of calcifying organisms, the effects of ocean nitrification, the altering impacts on the developmental stages of invertebrates, the present-day state of California’s Current System and how this affects consumers and the economy. Lastly, this paper will provide different solutions to some of the problems associated with ocean acidification…
Ocean acidification is negatively affecting our oceans and its marine inhabitants. Ocean acidification is a naturally occurring process where ocean water absorbs carbon dioxide from the atmosphere. The chemical process of water molecules binding to carbon dioxide creates carbonic acid and frees hydrogen ions causing an increase in acidity. Marine animals can’t survive in water that is too acidic. Marine ecosystems are detrimentally affected by this chemical reaction.…
Due to the carbon dioxide levels increasing over time, the acidification of the ocean has become much stronger. Behavior patterns are not the only thing changing because of the rising temperatures; the migration patterns are changing as well. I chose to analyze a marine science article published by Inside Science News. The article, “Ocean Acidification May Change How Sharks Behave,” was based on a study that was trying to prove how swimming patterns and temperature changes would affect a shark’s behavioral patterns.…
Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…
Many can probably guess that lethal coal mines, the offshore drilling explosions and the catastrophic Gulf of Mexico oil spill as being a principal culprit of ocean acidification but have you ever thought that global warming actually has a much larger role in ocean acidification than we think? That is why we need to be educated on what ocean acidification is, what are the effects of ocean acidification, who are the ones being mostly affected, and how can we resolve this issue. According to NOAA (National Oceanic and Atmospheric Administration), ocean acidification is defined as, “a reduction in the pH of the ocean over an extended period of time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere”. Carbon dioxide that has…
(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” (Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is. (Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that liberal bullshit,” so I set out on a mission to prove him wrong by conducting research with the goal of fully understanding the climate change debate. (Preview the Body)…
It is crucial that society begins to take action and take care of the ocean because it makes up 71% of the Earth. For example, acidification, or the reduction in the Ph levels of the ocean as a result of carbon dioxide is affecting the ocean and the marine life alike. Pollution, such as the discharge of fossil fuels from cars, and overfishing are also significant causes of ocean acidification. The carbon dioxide that the ocean absorbs also heats the water, which creates higher sea levels, the melting of polar ice caps and other extreme weather such as intense rainfall and on the opposite side of the spectrum, droughts. Acidification is also harmful to organisms that use calcium carbonate to make shells for protection.…
