0000001831 00000 n 0000003297 00000 n 0000010639 00000 n School is a great opportunity for your community to engage ocean and coastal acidification. 4) Partner with local community efforts to mitigate the driver behind ocean acidification  - excess CO2 - such as community supported agriculture, bike & car shares and other public transportation options. Let’s start with some basic chemistry concepts. NOAA Research, utrients from runoff and fertilizers can cause increases in algal growth. Creating awareness is the first step to taking action. 0000025422 00000 n 0000002716 00000 n Reducing the carbon footprint of member cities involves municipalities encouraging the use of alternative technologies, but also individuals willing to take any of the 11 steps recommended to reduce their personal carbon footprint. ]�k�*&�K���/��`=|]~]��/ZAB�U&jK��=:�6/4ʓ����������������KR� oL�^}�p����7���/���ېAr�~�q��qè ��ر� �8�. However, these carbonate ions (CO32-) are an important part of calcium carbonate (CaCO3) structures, such as sea shells and coral skeletons. By minimizing local stresses, some ecosystems may prove more resilient to ocean acidification. School is a great opportunity for your community to engage ocean and coastal acidification. 0000002875 00000 n 1) Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Here are 10 simple things you can do at home, around town, on the water, or anywhere! An official website of the United States government. This dissolved CO2, sometimes referred to as an “acid gas,” reacts with seawater to form carbonic acid (H2CO3). ... Koweek and Caldeira are grounded in their optimism for solutions to stop ocean acidification around the world. 0000006752 00000 n Coastal acidification includes local changes in water chemistry from freshwater river inputs and excess nutrient run-off (e.g. 0000005041 00000 n 0000016743 00000 n We need to reduce carbon pollution by burning fewer fossil fuels and using more renewable energy. Actually, we can tackle ocean acidification on multiple fronts. Email Us: noaa.oceanacidification@noaa.gov, NOAA Privacy Statement| This exchange, in part, helps to regulate the planet’s atmospheric CO2 concentrations, but comes at a cost for the oceans and life within it; from the smallest, single celled algae to the largest whales. 0000004868 00000 n 0000003164 00000 n You've taken the first step to learn more about ocean acidification- why not spread this knowledge to your community? This is causing a fundamental change in the chemistry of the ocean from pole to pole. School is a great opportunity to help preserve the abundance and diversity of life in the ocean that we enjoy today by learning about and taking action on ocean and coastal acidification. The ability of some fish, like clownfish, to detect predators is decreased in more acidic waters.Studies have shown that decreased pH levels also affect the ability of larval clownfish offsite link to locate suitable habitat. The NOAA Ocean Acidification Program coordinates research, monitoring, and other activities to improve our understanding of how (and how fast) the chemistry of the ocean is changing, how variable that change is by region, and what impacts these changes are having on marine life, people, and the local, regional, and national economies. Since the industrial revolution, the atmospheric concentration of carbon dioxide has increased from 280 to over 400 parts per million due to the burning of fossil fuels such as coal, gas, and oil, along with land use change. These links provide resources for educators and students to raise awareness of pollution that causes ocean and coastal acidification and how to reduce those sources: Acid rain: Kid's Site for Grades K-3 and Student's Site for Grades 4-5. School is a great opportunity to help preserve the abundance and diversity of life in the ocean that we enjoy today by learning about and taking action on ocean and coastal acidification. 2) Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification, 3) Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future. The higher the hydrogen level, the more acidic the solution. From the SelectedWorks of Ryan P Kelly January 2013 Ten Ways States Can Combat Ocean Acidification (and Why They Should) Contact Author Start Your Own Ocean acidification is occurring because our ocean is absorbing carbon dioxide from the atmosphere, leading to lower pH and greater acidity. Download this infographic Volunteer for cleanups at the beach and in your community. By minimizing local stresses, some ecosystems may prove more resilient to ocean acidification. 0000003019 00000 n 0000004695 00000 n Can seagrass help fight ocean acidification? 0000002087 00000 n The ability of an ecosystem to cope with acidification is influenced by the amount of local stressors it needs to contend with, such as high nutrient input or changes in temperature or salinity. 0000001717 00000 n Adaptation approaches fostered by the OAP include: Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare, Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes, Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally. 0000001809 00000 n When these algal blooms die, they consume oxygen and release carbon dioxide. 0000003909 00000 n As a community member, you can take a larger role in educating the public about ocean acidification. Visit our Education & Outreach page to find the newest tools! The increase in the concentration of hydrogen ions (H+) from these reactions causes the seawater to become more acidic (and is what the “H” in “pH” represents), hence the term “ocean acidification” and link to pH. United States Environmental Protection Agency. As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification. The increase in hydrogen ions (H+) produced by the uptake of CO2 reacts with carbonate ions (CO32-) to form bicarbonate (HCO3-), making carbonate ions relatively less abundant. NOAA| Visit our. 0000025892 00000 n U.S. Department of Commerce| Increases in carbon dioxide (CO2) in the atmosphere drive corresponding increases in dissolved CO2 within the surface waters of our ocean. 0000003573 00000 n 0000004042 00000 n While ocean acidification refers to the global change in ocean chemistry from atmospheric inputs of carbon dioxide, coastal acidification is another mechanism by which coastal chemistry can change. What is ocean acidification, and why is it so important to ocean sustainability and therefore to the SDG agenda? Educators play an essential role by introducing students to pivotal issues and encouraging action in your classroom, your school, your homes, and in your community. When these algal blooms die, they consume oxygen and release carbon dioxide. T. he ability of an ecosystem to cope with acidification is influenced by the amount of local stressors it needs to contend with, such as high nutrient input or changes in temperature or salinity. ���� Here are some simple things you can do to help our ocean. After all, today’s students will bear the consequences of increasing acidity and its impact on life as we know it. The world’s surface ocean is tightly linked with the atmosphere and absorbs huge amounts of carbon dioxide each year.
