See  \npage 6.  \nThis curriculum module was developed for the NOAA Ocean Data Education (NODE) Project by Caroline Joyce, Todd Viola and Andrew Amster in collaboration with the NOAA Coral Reef Conservation Program ([http://coralreef.noaa.gov](http://coralreef.noaa.gov)) and the National Oceanographic Data Center. This project has been made possible with support of the National Marine Sanctuary Foundation.  \nScientific and technical advice was provided by Dr. Joseph Salisbury, Assistant Research Professor at the University of New Hampshire.  \nPermission is hereby granted for the reproduction of this lesson without alteration and on the condition that the acknowledgment above is cited.  \nUnderstanding Ocean Acidification  \nPrior Knowledge  \nThis curriculum module is designed for students who are taking highschool chemistry. Students should already have some experience with the following:  \n􀀁 Understanding and reading the pH scale.  \n􀀁 Knowledge of the carbon cycle.  \n􀀁 Using scientific notation to express large and small values.  \n􀀁 Reading chemical equations.  \nTable of Contents  \nThe Basics of Ocean Acidification...........................................................2  \nLesson Overview......................................................................................3  \nUsing the Technology...............................................................................5  \nNational Education Standards..................................................................6  \nLevel 1: Measuring Ocean pH..................................................................9  \nLevel 2: The Ocean-Carbon Connection................................................ 19  \nLevel 3: The Oceans & Carbonate Chemistry........................................33  \nLevel 4: Aragonite Saturation & Marine Calcifiers................................45  \nLevel 5: Design Your Own Investigation................................................56  \nCompleted May 2011  \nWeb Links  \nFor links to helpful websites about Ocean Acidification, visit  \n[www.dataintheclassroom.org](www.dataintheclassroom.org).  \nThe Basics of Ocean Acidification  \nBurning fossil fuels releases carbon dioxide into Earth’s atmosphere. This not only leads to a warmer Earth (i.e., global warming, the greenhouse effect), but also changes the chemistry of Earth’s oceans.  \nThe ocean is a “carbon sink,” which means that it removes CO2 from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels. However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. When CO2 dissolves in seawater, it leads to decreased pH levels. The ocean becomes less alkaline. This is referred to as ocean acidification.  \nAs the ocean water becomes less alkaline, there is a resulting decrease in the amount of carbonate ions available for many marine organisms to form their calcium carbonate hard parts. Coral polyps are less able to precipitate the mineral aragonite, which they use to build or rebuild their skeletons. This means that a coral reef might stop growing and become more vulnerable to erosion. Other marine organisms, such as oysters, might also be harmed.  \nUnderstanding ocean acidification is important for citizens engaged in debating global climate change issues, policies, and solutions.
