How Does Ocean Acidification Affect Ocean Life?

829 words - 4 pages

Introduction: The question that the researcher is trying to answer is if there is acidification alters oceanic life due to a change in pH. The hypothesis is if there is a change in pH in the tank then the fish will have altered feeding patterns, stunted growth, and abnormal behavior. Even if there is a slight change in pH distinct abnormalities will occur. This simulation of this experiment will represent a sample for the whole ocean and how pH has affected ocean life due to runoff and toxic waste put into the water.

Methodology: The experimenter used two ten gallon tanks. One tank will be used for the controlled group and the other tank will be used for the experimental group. Each tank ...view middle of the document...

The controlled group tank was cleaned every month and the experimental group was cleaned every time there was a pH change.

Results and Analysis: The experimental group was exposed to altered pH levels. Each change added more stress to the fish. The higher the pH became the less outer slime the fish had. The higher pH levels also caused the fish to reduce it’s total movements making the fish travel less and the fish started to eat less. The above average levels stunted the fish’s growth in some cases. In the experimental group tang one was three inches and six centimeters and tang two was three inches and four centimeters. Clownfish one was two inches and two centimeters and clownfish two was two inches and three centimeters. Damsel one was two inches and three centimeters and damsel two was two inches and five centimeters. After the first change to 8.6 all fish experienced a slight change to its eating habits and began to move less. The second change in pH came with more noticeable changes. At the pH of 9 all fish lost it’s slime making it’s skin more dry. Both tangs shrank one centimeter, clownfish one shrank one centimeter, and the damsels were left unaffected. Third change occurred and deaths began to occur clownfish one and damsel one died. The rest shrank one...

ocean acidification Essay

1265 words - 6 pages the ones near the bottom of the food chain. What role does the carbon dioxide really play in ocean acidification though? When excess amounts of carbon dioxide are dissolved in the oceans it binds with the water molecules to produce carbonic acid. (H2O + CO2 → H2CO3) Why is this a problem? The carbonic acid increases acidity mainly near the ocean surface where it is easier for the carbon dioxide from the atmosphere. The carbonic acid is what

Ocean Acidification Essay

668 words - 3 pages Ocean acidification is an increasing problem that many people do not realize or understand. Ocean acidification is a result of excessive amounts of anthropogenic carbon dioxide dissolving in the ocean. The carbon cycle helps dissolve carbon dioxide into ocean water for photosynthetic sea creatures, but too much goes in and not enough comes out. The excess carbon dioxide reacts with the water to form carbonic acid which is a weak acid. Carbonic

( This leads to an overall decrease in the shellfish population. Change in atmospheric carbon dioxide has also caused brittle shells because the carbonate that they have used to form their shells is being broken down

Ocean Acidification: Impact of CO2 on Ocean Water

1535 words - 6 pages got mixed with the ocean water resulting in ocean acidification (Buffie and Carr, 2010). Ocean acidification is the decrease of pH in the oceans due to absorption of CO2 in the atmosphere (Fabry, 2008). Over the past three hundred million years ocean pH levels have been 8.3, however in the past 200 years the pH level of oceans’ have reduced to 8.1, an increase of 25% in the acidity level (Bednaršek, 2012). The CO2 in the ocean reacts with water to

2360 words - 10 pages specifically focuses on how the increased CO2 absorption into the ocean specifically affect shellfish and the greater impacts of this phenomenon. Saturation level: The formation of calcium carbonate (CaCO3) is thermodynamically favored by the abundance of the reactants, dissolved calcium, and carbonate ions. Although the amount of oceanic dissolved calcium remains relatively constant, the oceanic carbonate ions decrease as atmospheric CO2

Ocean acidification summary and - 11 IB - notes

506 words - 3 pages Ocean Acidification As you know, CO2 from the atmosphere dissolves into seawater. Let’s look at this process in more detail: First, CO2 reacts with water to form carbonic acid (H2CO3-): Equation 1: CO2 + H2OH2CO3- Carbonic acid can then dissociate into bicarbonate (HCO3-): Equation 2: H2CO3-H+ + HCO3- Bicarbonate can then dissociate into carbonate ions (CO32-): Equation 3: HCO3-H+ + CO32- There are two very important biological and chemical

It will discuss the consequence on marine organisms. But first it will introduce you to El Nino.El Nino is a disruption of the ocean-atmosphere system in the tropical pacific, yet it has important consequences for weather around the globe. It is caused by the relaxation of the trade winds in the

Many individuals may wonder how scientists can effectively project the future of our oceans despite no historical recordings of ocean acidification. Scientists have found a real life petri dish of seawater conditions similar to what scientists predict the ocean to be like by the year

Ocean Acidification and Its Effect on Climate Change

2180 words - 9 pages Ocean acidification is one of the highest environmental concerns that involve the change in climate. Ocean acidification is caused by uptake of rising atmospheric CO2. This increase in CO2 is from burning fossil fuels. Not only does it affect humans it affects numerous marine ecosystems. Coral reefs are one of the most affected systems by ocean acidification. Coral is one of the main ecosystem engineers in these ecosystems without them; the

Although Dr. Robles is hesitant to speak about how ocean acidification will adversely impact California’s shelled organisms, he expressed his concern about the effects of high ocean temperature on aquatic plant life. Similarly, Gruber, et al. believe that researchers do not know how exactly lowered aragonite and pH levels will affect many

Ocean Acidification Essay

2019 words - 9 pages organisms that rely on certain water conditions to maintain vital functions and the environment which is damaged by highly acidic waters. There is great variation in the acidity of each of the oceans, differences caused by the chemical composition of the ocean and biogeography. Understanding of the potential impacts of ocean acidification is relatively new to the scientific community and therefore little is known on how to counteract anthropogenic influences. Although reducing the amount of carbon dioxide produced will in turn reduce the lowering of the oceans acidity levels and reduce negative impacts on the environment and marine organisms.
