Transcript of Human Impact (Ocean Acidification)

Ocean Acidification By:Elizabeth Hettinger
Abner Hernandez Lima Introduction What is ocean acidification? Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of anthropogenic carbon dioxide (CO2) . How is ocean acidification caused? http://www.duke.edu/web/nicholas/bio217/spring2010/chang/Causes%20of%20Ocean%20Acidification.htm Water acidification is cased by the dissolution and reaction of carbon dioxide (CO2) into water. Cited page Clown fish Petition
Was caused by Ocean Acidification
Inspired the movie "Finding Nemo" Event #1 (clown fish) Event #2 (Blue Sea Slug) http://www.reefed.edu.au/home/explorer/hot_topics/coral_bleaching http://www.biologicaldiversity.org/news/press_releases/2012/reef-fish-09-13-2012.html Event #4 http://www.treehugger.com/slideshows/ocean-conservation/10-marine-species-brink-mass-extinction-due-ocean-acidification/page/2/

Feeds on poison jellyfish
Without these slugs then there will be a growth of Jellyfish. The foundation of arctic food webs
Helps support larger marine animals like whales and polar bears
If the oceans become more acidic than the pteropods will dissolve. Event #3(Pteropods) The Great Barrier Reef It looks' cool but, did you noticed that it lost its' color
By: ocean Acidification * www.whitsundaybb.com.au/great-barrier-reef.php HELP ME!!!!!1 * The Great Barrier Reef World Heritage Area is 347 800 square kilometres in area ( an area bigger that the United Kingdom, Holland and Switzerland combined). It is the largest World Heritage Area and marine protected area in the world. * over 1500 species of fish, about 400 species of corals, 4,000 species of molluscs, 215 species of birds, 6 species of sea turtles and a host of sponges, anemones, worms, crustaceans, shells, sea stars, and urchins. Coral Reefs * If one of the animals in the ocean is affected by this ocean acidification, then the rest of the animals are affected because the food web in the ocean. + www.coral-reef-info.com The reef crest is the shallowest part of the reef, and lies between the shoreward, protected lagoon and the outer reef face. It can be seen from the shore as an irregular, darkish band paralleling the shore. CONCLUSION In conclusion, we know that ocean acidification can harm the environment we live today. So how can we stop this acidification from spreading around the whole ocean on earth?.
STOP USING ALLOT OF VEHICLES, MACHINES, THAT CAN RELEASE CARBON DIOXIDE IN THE SKY AND THEN COMING BACK DOWN AS RAIN POLLUTING THE WATER, WERE SEA ANIMALS LIVE TODAY. Event # 5 (Squid) The acidification interferes with the squid's blood.
The acidification of the water makes it harder for the squid to absorb oxygen.
The squid is an important part of the marine food web.
