  1. The Great Barrier Reef By: Ben Litwiller

  2. Intro. • http://video.nationalgeographic.com/video/places/parks-and-nature-places/oceans/oceans-barrier-reef/

  3. Location • The great barrier reef is located out the northeast shores of Australia.

  4. Topography • largest extent of coral reefs on Earth • geographic range (24°30'N to10°41'S, 145°00' to 154°00'E) • extends for more than 2000 kilometres within the Coral Sea off the eastern coast of Australia.

  9. Plants • Mangroves • make up the third type of plant growing near reefs • More than 50 species of mangroves exist in the world. • Florida's boasts about 469,000 acres • found along the state's southern coast.

  10. Plants

  11. Plants

  12. Plants • Blue-green algae • are more appropriately known as cyanobacteria • originally thought to be a type of algae • bacteria form green tufts on the reef • which forms sometimes forms blooms in tropical waters.

  13. Plants • Brown algae • contain an extra pigment • abundant in cooler climates • a few species can be very common in summer on inshore

  14. Plants • Golden algae • are concerned about extensive blooms of seabed algae known as 'golden noodle algae • Scientists have identified the bloom-forming alga as Chrysocystisfragilis • has been found at Palau, Pohnpei and Hawaii.

  15. Endangered Animals • Whales and dolphins • Dugong • Marine turtles • get tangled up in fishing lines

  22. Strange Animals

  23. People • People can go snorkeling, diving, NO HURLIN ON helicopter rides and cruises THE SHELL DUDE

  24. People • Great Barrier Reef contributes $6.4 billion a year from the tours • employs more than 60,000 people. • The interconnected reef system faces increasing pressure from climate change

  25. Jobs for people • Aquariums • Visitor service officer • Marine Biologists • Fishermen • Tour Guides

  26. Unique Features • the clownfish can actually help the sea anemones to breathe and can help them to aerate themselves • Sea anemones gives the clownfish a place to live in exchange • http://video.nationalgeographic.com/video/coral-reefs • There are more symbiotic relationships similar to this found in the G.B.R.

  27. Relationships • Commensalism • the pearlfish uses the sea cucumber for a hide-out from predators • lives in the sea cucumber’s anus • Mutualism • orange coral crab lives in and feeds off of the coral • coral benefits as the resident crab cleans it and protects it • Parasitism • Sea spider gains food and nutrients from coral • this relationship bleaches the coral

  28. Coral • Attached to the ocean floor • Waste produces products for photosynthesis for the algae • Algae produces products need for the coral to grow • Is home for most animals in the reef

  29. Environmental concerns • lost more than half its coral cover in the past 27 years. • Experts say storms, starfish and bleaching linked to climate change are to blame.

  30. Environmental concerns • global warming • overuse from tourism • Fishing • farming • development on the coast and pollution both in the water and on the land.

  31. Before After

  32. Solving the problems • * 30-50% of reefs to be set aside as "no take" or no fishing zones for long term protection * larger fines for fishing offenses * greater use of technology to enforce no fishing zones.

  33. Conclusion • Beautiful place • Cool animals • All around fun place to go on vaction.

  34. Food web of the G.B.R. =P =P.C. =S.C. =T.C.

  35. 5 questions • What are the four endangered species I minced in the P.P.? • What can people do when visiting the reef? • What is the biggest problem with keeping the reef healthy? • What is the olds fish in the G.B.R.? • How many speices of sea snakes are there?
