The Dangers of Ocean Acidification
Author: Scott C. Doney
A. List the major ideas, concepts or key points- point by point
B. Summarize the AUTHOR'S main point or idea- at LEAST 1-2 paragraphs
As the years passed by more, and more carbon dioxide has been produced, and more carbon dioxide has been absorb by the ocean. The ocean takes in 1/3 of carbon dioxide. When the ocean absorbs carbon dioxide it starts to become acidic. The acidity of the ocean water causes the shells of organisms to dissolve. These shells are made up of calcium carbonate and are in two forms of calcite or aragonite. Coral reefs also have shells that other sea creatures rely on for shelter. The ocean is what takes up most of the earth, and if it starts to become more acidic the food chain in the ocean may become unbalanced.
C. Write a reaction paragraph to the article stating your own thoughts on the topic, using specific citations from the article to support your views.
The more carbon dioxide we produce, the more acidic our ocean becomes. Ocean acidification is what it's called and what we need to do is try to reduce our emissions of carbon dioxide. Carbon dioxide affects the organisms in the ocean. Carbon dioxide mixed with water causes it to beomce acidic. The acidity of the water causes the shells of organisms to dissolve. Every second of every day we produce carbon dioxide. People all over the world should be aware that our ocean is in more danger than we think. With organism shells dissolving, this can result into the food web being affected. With everyone in the world exhaling, and factories producing carbon dioxide won't just affect the ocean, but it will affect everyone else also.
So what?:
Says Who?:
What if?: All organisms shells dissolved
What does this remind of?:
The Movie "The Lorax" because in that movie the Once-ler wasted natural resources, that were used for his business. With him only focused on his business, he didn't realized that he started affecting everything in the ecosystem, such as animals, natural resources, and the environment. Like "The Lorax" we don't realized what carbon dioxide might affect.
A. List the major ideas, concepts or key points- point by point
- Ocean acidification may contribute to the extinction of coral reefs
- O2 will cause saturation horizon or aragonite and calcite to move closer to surface.
- The ecosystem will be affected when pteropods have to leave the area
- The ocean absorbs carbon dioxide, which causes it to become acidic
- Shells can end up disintegrating
- Calcite and aragonite are the two forms that calcium carbonate comes in
- Ocean has absorbed half of all fossil carbon burned since the industrial revolution
- Land plants gain from the increase of carbon dioxide in the atmosphere
- Supersaturated is warm water
- Unsaturated is cold water
- Ocean acidification can lead to coral reefs becoming extinct
- Coral depend on the plankton & secrete their calcium carbonate
- Hydrogen carbon are created which combine with carbonate forming bicarbonate, which causes a reduction in carbonate ions
- The acidity will affect creatures who rely on carbonate ions to build their shells badly
- High carbon dioxide will benefit phytoplankton
- 40% of all Carbon Dioxide is still in the atmosphere from not being absorbed by plants or the ocean
- A drop in one pH unit means an increase in hydrogen ion concentration
- Carbon dioxide from fossil fuels also go into the ocean

So what?:
- Shells are dissolving
- Carbon dioxide is being absorb by the ocean
- pH level is decreasing
- Coral reefs can't provide shelter
- Coral reefs may become extinct
Says Who?:
- Christopher Landon
- Roger Reville & Hans Suess
- Robert H. Socolow
- Victoria J. Fabry
- Rik Wanninkhof
- Nicolas Gruber
What if?: All organisms shells dissolved
- The food chain would be unbalanced
- There would be any protection
- There wouldn't be any shelter for other organims
- Some species would die out
