Ocean Acidification and Its Effect on Climate Change Essay

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 ecosystem will not be as healthy or sustainable for other organisms. The species richness and evenness will decrease tremendously due to this. Corals help set the structure for the ecosystem so fish can use it for protection against predators. This structure allows many organisms to come in and make it …show more content…
Sensitivity of different organism and how some organisms are more affected then others. How valuable Echinoderms are to the marine environment. Population naturally exposed have an advantage over population not naturally exposed when encounter with change in pH and what some of these facts are.

According to research done by K. R. N. Anthony et al, carbon chemistry of reef water varies over the course of the day and between tidal cycles unlike the pace ocean waters acidify. They analyze how corals and non-calcifying macroalgae, modify the carbon chemistry of reef water on shallow water systems. The aragonite saturation state of the water is a key indicator for how much calcification occurs. The aragonite saturation state has a chemical reaction that looks like this Ca^2+ +CO3^2- ↔ CaCO3 which can go both ways depending the how much substance there is present. When ocean acidification occurs from CO2 there is less carbonate ion CO3^2-in the water so the reaction shifts towards the side that decrease aragonite. The lower this saturation state is the more calcification that will occur. Anthony found that the daytime rate of coral net calcification was 62.8 ± 2.5 mmol m_2 h_1. While at the night the rate of calcification was 40 percent that of the day rate 26.3 ± 1.5 mmol m_2 h_1. For the macroalgal assemblage
