Great Barrier Reef

Transcript: Great Barrier Reef Species Reefs The Great Barrier Reef is the biggest coral reef in the world. There are three different kinds of reefs in the Great Barrier Reef: Fringing Reefs Fringing Reefs are coral structures that are attached to the mainland or to continental islands. In the Great Barrier Reef, most fringing reefs are found around islands. Fringing reefs are probably the reef type most commonly seen by visitors. Platform Reefs Platform Reefs are known as patch reefs and are scattered in the calm, shallow waters between the mainland and the edge of the continental shelf. They are usually round or oval patches and often tend to be broken up. Ribbon Reefs Ribbon Reefs only occur in the northern part of the Great Barrier Reef. They form along the edge of the continental shelf and can grow so high that they form narrow walls. Answer: The Great Barrier Reef is unique in many different ways. From coral structures to its size, there is something unique about the Great Barrier Reef. Heart Reef is coral in the Great Barrier Reef that is in the shape of a heart. It was discovered in 1975 by a pilot flying over the reef.. People can only see it from an airplane because of its protected status. Size Heart Reef By: Amy Waughen The Great Barrier Reef is the largest structure formed by living creatures. It is about the size of California! It stretches over 2000 kilometers in length and is the only natural structure that can be seen from space. In the Great Barrier Reef, there are 3000 reefs and 900 islands. EQ: What makes the Great Barrier Reef unique? Source: www.RedBubble.com The Great Barrier Reef has many different species of animals. There are 30 species of whales, 215 species of birds, 6 species of sea turtles, and 125 species of sharks and stingrays. Also, there are 49 species of pipefish, 17 species of sea snakes, and 1500 species of fish.

Transcript: Awareness In 2007, UNESCO published on the negative effects of climate change on the Great Barrier Reef In 2009, the GBR Park Authority published the Great Barrier Reef Outlook Report, a comprehensive assessment of the health of the Great Barrier Reef that identifies the key challenges facing it now and into the future. The Problem Long-term change in coral cover This is a graph of todays sea surface temperature anomalies. Image is provided by statellite data from NOAA analyzed to a 50 km resolution. Color bars represent .5 degrees Celsius anomaly increments, red is positive anomalies, blue is negative anomalies. 1,500 species of fish 411 types of coral 1/3 of the world's soft corals 132 species of sharks and rays Six of the world's seven species of threatened marine turtles More than 30 species of marine mammals Thousands of molluscs, sponges, worms and crustaceans 630 species of echinoderms (starfish and sea urchins) 215 species of birds, including 22 seabirds Degradation of coral reefs. a, Results of a meta-analysis of the literature, showing a decline in coral cover on the Great Barrier Reef. Each point represents the mean cover of up to 241 reefs sampled in each year. b, The recorded number of reefs on the Great Barrier Reef, Australia, substantially damaged over the past 40 yr by outbreaks of crown-of-thorns starfish (COTS) and episodes of coral bleaching. Cases of coral bleaching observed. Notice that the regions of the oceans that have higher temperatures have the most cases of coral bleaching Diversity in the Great Barrier Reef http://www.climateshifts.org/?p=6348 http://www.wwf.org.au/our_work/saving_the_natural_world/oceans_and_marine/priority_ocean_places/great_barrier_reef/ Climate Change: increasing sea temperature, ocean acidification and rising sea level Introduction: The Great Barrier Reef 2,300 kilometres along Queensland coast Over 2,900 reefs 940 islands and cays 345,000 square kilometres- larger than UK and Ireland combined!

Great Barrier Reef

Transcript: Saving Nemo And The Great Barrier Reef By Bailey Wegener What Is Coral? Even though coral looks like a plant or rock it is actually an animal! It makes a hard outer shell from calcium and carbon dioxide to protect itself from predators. It reproduces by making polyps and the polyps grow and make coral in another location increasing the number of coral When the coral produces the poylps they float around in the water until they find a hard surface or coral reef. Once they do they will start to grow but if it's to hot or there isn't enough light they will die. Once one coral has established itself it will start to make a colony. Coral gets 2% of its food from its tenticles getting food by pushing them outside the hard outer shell and grabbing the little particles in the water. The other 98% is gained from algae that the coral grows inside itself. Where is the great barrier reef? What are the main threats to the great barrier reef? One of the main threats to the reef is the crown of thorn star fish. These starfish eat the coral polyps and the coral. The main predator to the crown of thorn star fish is the triton but the triton has been killed because the shell is greatly prized by us humans. Name two types of coral Hard and soft coral What kind of marine animals live in the barrier reef? Animals like sponges, fish, dolphins, sea snakes, molluscs, echinoderms and seabirds What are 3 ways people use the Great Barrier Reef People use the reef for fishing, diving and snorkling. What are people doing to protect the Great Barrier Reef They are putting rules in place to stop the destruction of the coral and also trying to stop littering and other things such as petrol from the boats. What is the main threat to the great barrier reef? The main threat in my opinion is the crown of thorn starfish I selected the crown of thorn starfish as one of the biggest threats because it destroys the habitats of the fish and other marine animals that live there. If i was in charge of the great barrier reef i would send divers down to decrease the number of crown of thorn starfish and not allow people to take triton to also naturally decrease the number of crown of thorn starfish. Thanks for watching my prezi! Rising sea tempretures causeing the algie in the coral to die and cause coral bleching. If the tempreture changes by .5 degree then the algie in the coral dies and causes coral bleaching

Great Barrier Reef

Transcript: The Great Barrier Reef The Great Barrier Reef is located in the water off the Queensland coast and is accessible from the port cities of Cairns and Port Douglas. The reef is enormous, bigger than the size of the UK, and it is the largest living being on earth. It is estimated at 500000 years old! What is the GREAT BARRIER REEF?? Abiotic factors: BIOTIC factors: Another major event in the reef's history, is the flooding that is occuring in Austrlia right now. The ocean water is not the same as rain water. The biome is also having to deal with the debree that the flood brings through the reef. A cow, a fridge, and a number of houshold items have washed up on shore. Who is helping save the reefs?? The WWF, ACTNOW, Species Conservation Unit, World Heritage Area, The Great Barrier Reef Marine Park Authority, Biodiversity Action Plan WHAT CAN WE DO? *Adopt an animal *Give a financial donation *Be aware of what you throw away and where it ends up - don't litter, don't pollute our water ways *Educate your friends and colleagues *Support local business and government initiatives to protect the reef *When enjoying any coral reef - don't touch, don't take away souvenirs, don't endanger the marine life *Advocate for the protection of our most precious natural wonderland on social networks *Call or Email a Politician to urge them to keep climate change at the top of their list of priorities The Great Barrier Reef US US humans often forget about the world we live in. We plug into the internet, our ipods, our tv shows, and it consumes us. BUT, the few times we get out and see the beauty of the world, we mess something new up. Humans have been damaging The Great Barrier Reef since they discovered it. Global warming is hurting the reef. We are killing the animals. We pull out organisms, we step on the coral, and we abuse the water that provides life for the reef. How are we going to change? www.PBS.org -Fish -Coral -Shellfish -Sea bird -Sea sponge It is the worlds largest ecosystem It was added to the natural heritage list It is made up of Coral polyps It is clear of water and full of life! It lays where the Indian and Pasific ocean's meet When ships travel over the reef they are required to pay close attention to their gas emissions. In 1770, Europeans started to colonize Australia. Captain James Cook's ship, The Endeavour, struck a reef one day. This is the first recorded discovery of The Great Barrier Reef. Some 30 years later, the colonists had circumnavigated the whole contenent of Australia and The Great Barrier Reef, as well as named it. This is a HUGE event in this biomes history. Humans for the first time, were messing with the biome, and would gradually destroy parts of it.
