2 Planning Document Second Rough Draft My issue: Ocean acidification is a complex process that has severe implications for our planet. It occurs when carbon dioxide is absorbed by seawater, which then reacts with water molecules to form carbonic acid. This reaction leads to a decrease in the concentration of carbonate ions in the ocean, making it difficult for marine organisms such as corals, mollusks, and plankton to form their shells and skeletons(Ocean Acidification, n.d). The reduction in carbonate ions has a ripple effect throughout the entire marine ecosystem. This is because these organisms are the foundation of the ocean's food chain. If they are unable to form their shells and skeletons, they become more vulnerable to predation and are unable to provide food for larger organisms. As a result, the entire food chain is disrupted, and entire ecosystems can collapse. Ocean acidification is primarily caused by human activities such as the burning of fossil fuels, deforestation, and industrial processes. As the concentration of carbon dioxide in the atmosphere continues to increase, so does the absorption of this gas by seawater, leading to a further decrease in pH levels. Given the severity of the problem, we must take steps to mitigate the effects of ocean acidification. This could include reducing carbon emissions, investing in renewable energy sources, and promoting sustainable practices. By taking action now, we can help preserve the health and biodiversity of our oceans for generations to come. My question: As carbon dioxide continues to be absorbed from the atmosphere and the ocean becomes increasingly acidic, the impact on marine wildlife and human communities who depend on the ocean is a growing concern. What are the potential consequences for these vulnerable populations?
3 My science resources: 1. My first source is titled "Effects of the ocean acidification on the functional structure of coral reef nematodes." For my research, I have selected a study that performed a mesocosm experiment to examine the impact of seawater acidification on phytal nematofauna. The study involved obtaining standardized samples using artificial substrate units, which were then exposed to varying levels of seawater acidification (Esteves et al., 2022). The researchers analyzed the phytal nematofauna response to these changes and drew insightful conclusions based on their findings (Esteves et al., 2022). The article's authors are highly credible, with extensive experience and knowledge in the field. The article provides valuable information regarding the effects of seawater acidification on phytal nematofauna and can serve as a significant reference source for future studies. Compared to other references, this source stands out due to its detailed analysis, comprehensive methodology, and accurate findings. 2. My second source is titled "The other carbon-dioxide problem; Ocean acidification." While researching, I stumbled upon a fascinating source that delves into ocean acidification and its relationship with carbon dioxide. The source captured my attention by providing a comprehensive and in-depth explanation of the chemical changes that occur in the ocean as it becomes more acidic. It is an excellent read that covers a wide range of information, including the various risks and consequences that marine creatures face due to ocean acidification (The Economist, 2010). The source emphasizes how these consequences can have a significant impact on human life as well. What I found particularly impressive about this source is that it was published by the Economist Intelligence Unit, which ensures that information has been

4 rigorously tested and peer-reviewed for accuracy. This source stands out from my other references due to its focus on the impact of ocean acidification and proposed solutions rather than presenting general facts and carbon dioxide information. The in-depth analysis of the effects of ocean acidification and its potential solutions makes it an invaluable resource for those seeking a comprehensive understanding of this complex issue. 3. My third source is titled " Ocean acidification impacts on coral reefs: From sciences to solutions." I selected this particular source because it provides in-depth insights into the effects of ocean acidification on coral reefs. It is crucial to understand this topic comprehensively, as it plays a significant role in my research on ocean acidification. Coral reefs are essential to marine ecosystems and the economies of certain coastal countries (Allemand & Osborn 2019). They serve as a natural habitat for many aquatic species, and their gradual degradation due to ocean acidification is a matter of concern. This source sheds light on the complex mechanisms that drive ocean acidification and how they impact coral reefs. It also delves into the economic implications of the loss of coral reefs, such as the impact on tourism and fishing industries in coastal regions (Allemand & Osborn, 2019). The authors of this academic journal are credible. Allemand specializes in marine organism physiology, especially reef-building corals, while Osborn is the Director of Environment Laboratories at IAEA, focusing on core environmental issues. The article provides detailed insights into the specific effects of ocean acidification on marine ecosystems, as opposed to my other two sources that offer more general information on acidification and its management. My audience and message:
5 As an ocean acidification researcher, I am eager to share my findings on this critical topic with an audience at an educational seminar. Specifically, this audience would be interested in learning about the environmental impacts of ocean acidification and how it affects marine ecosystems. However, I recognize that not all attendees may have a solid scientific background, so it is important to provide context and detail on the causes and effects of ocean acidification and potential solutions to address it. I will present the information clearly and concisely. To accomplish this, I will provide an overview of ocean acidification, briefly explaining how it occurs and its impacts on marine life. I will also highlight the most recent research and findings related to this topic, specifically emphasizing the urgency of addressing this issue and the potential consequences if we fail to act. In addition, I will provide examples and case studies of successful initiatives and programs that have been implemented to help mitigate the effects of ocean acidification. By doing so, I hope to inspire and motivate attendees to take action and become advocates for positive change in their local communities. Identify principles: My research has revealed that releasing carbon dioxide into the atmosphere has increased ocean acidity, which has severe consequences for marine life (Murphy & Raisman, 2013). This process, known as ocean acidification, occurs when carbon dioxide dissolves in seawater, forming carbonic acid (Murphy & Raisman, 2013). As a result, the pH level of the ocean decreases, making it more acidic. This can negatively impact marine ecosystems, such as coral reefs, by inhibiting the growth and reproduction of organisms vital to their survival. Furthermore, it can have far-reaching consequences for human populations that rely on the ocean for food and livelihood.
6 Explain principles: My investigation has uncovered a crucial link between the increased carbon dioxide emissions and the rising ocean acidity levels. This phenomenon, widely recognized as ocean acidification, results from carbon dioxide dissolving in seawater and forming carbonic acid (Murphy & Raisman, 2013). The ocean's pH level decreases, rendering it more acidic, leading to severe consequences for marine life. The delicate balance of marine ecosystems, such as coral reefs, is disrupted, and the growth and reproduction of organisms vital to their survival are inhibited (Murphy & Raisman, 2013). These changes can affect people relying on the ocean for sustenance and livelihood. My research findings demonstrate the harmful effects of carbon dioxide on the ocean, which is of utmost importance to address. My experimental question and hypothesis: I plan to conduct experimental research to examine the link between carbon emissions and ocean acidification. Specifically, I will investigate the question, "Can reducing carbon emissions help mitigate the impacts of ocean acidification on marine life?" Through this research, I hope to contribute to our understanding of this critical issue and identify potential solutions to protect our oceans and the life it supports. Ocean acidification occurs when carbon dioxide from the atmosphere is absorbed by seawater, leading to a reduction in pH levels (Esteves et al., 2022). This process may have dire consequences for marine life, including the inability of some organisms to form shells (Esteves et al., 2022). While reducing carbon emissions is one potential solution to this problem, its effectiveness is still being studied. To further our understanding of this critical issue, I intend to conduct experimental research to explore the relationship between carbon emissions and ocean acidification (Esteves et al., 2022). Specifically, I will investigate whether reducing carbon emissions can help mitigate the impact of ocean acidification on marine

7 life. The findings from this research will help identify potential solutions to protect our oceans and the life they support. My explanation: To better understand the impact of carbon emissions on ocean acidification, scientists use complex computer models that simulate different scenarios (Montero et al., 2022). These models consider various factors, including the amount and type of emissions, ocean currents, and the impact of other environmental variables such as temperature and salinity. Using these models, scientists can predict the potential long-term effects of carbon emissions on ocean acidity levels. For example, they can estimate how quickly pH levels might change in different ocean parts under different emissions scenarios and how these changes might impact marine ecosystems. This information can help policymakers make informed decisions and take action to mitigate the negative impact of human activity on our oceans. For example, policies might be implemented to reduce carbon emissions from industrial processes or transportation.
