The Great Barrier Reef lies off the northeastern coast of Australia and is the largest structure ever made by living organisms including human beings, consisting of the skeletons of tiny coral polyps and hydrocorals bounded together by the soft remains of coralline algae and microorganisms.
The reef is the product of over 350 species of coral and red and green algae. The number of coral species in the northern section of the reef exceeds the number (65) of coral species found in the entire Atlantic Ocean. Polyps are the live organisms inside the coral, and most are less than 0.3 in (8 mm) in diameter. They feed at night by extending frond-like fingers to wave zooplankton toward their mouths. In 1981, marine biologists discovered that the coral polyps spawn at the same time on one or two nights in November.
Their eggs and sperm form an orange and pink cloud that coats hundreds of square miles of the ocean surface. As the polyps attach to the reef, they secrete lime around themselves to build secure turrets or cups that protect the living organisms. The daisy- or feather-like polyps leave limestone skeletons when they die. The creation of a 1 in (2.5 cm) thick layer of coral takes five years. Animal life forms flourish on and along the reef, but plants are rare.
The Great Barrier Reef has a distinctive purple fringe that is made of the coralline or encrusting algae Lithothamnion (also called stony seaweed), and the green algae Halimeda discodea that has a creeping form and excretes lime.

One of the seven wonders of the natural world, the Great Barrier Reef lies in the clear blue waters off the northeast coast of Australia. Spanning 14 degrees of latitude, this complex reef system is not only the greatest expanse of coral in the world, it is the Earth’s largest living structure, a massive, beautiful, and ancient biological phenomenon of bewildering diversity and immense ecological significance. Habitats within the reef mosaic include the coral reefs themselves (some 3,000 individual reefs), sponge gardens, sea grasses, mangroves, continental islands, and coral cays, which together help support a rich assemblage of marine and terrestrial life, including more than 1,500 species of fish, 200 species of birds, six species of sea turtles, whales, dolphins, and dugongs.
This graduate course program is offered jointly with Reef HQ Aquarium, Australia’s National Education Centre for the great barrier reef from space. Reef HQ Aquarium is a unit of the great barrier reef from space Marine Park Authority, which holds responsibility for the management and conservation of the Great Barrier Reef. Located in Townsville, Queensland, Reef HQ Aquarium houses the world’s largest living coral reef exhibit.
During the field portion of this course, we will be sleeping near the corals in the aquarium itself, venturing forth on several excursions for direct research on the Great Barrier Reef, and hiking in some of Australia’s unique terrestrial habitats. Discussion topics include a range of marine science issues, as well as citizen engagement in marine science and environmental stewardship. Reef HQ Aquarium promotes reef stewardship through public exhibits, field programs, sustainability certification for tour operators, reef videoconferencing, and through school initiatives such as the successful Reef Guardian program, which engages hundreds of schools in reef conservation. Reef HQ Aquarium is also increasing its sea country partnerships with Aboriginal and Torres Straight Islander people to support traditional ecological knowledge and stewardship of the reef environment. This course supports advanced study of coral reefs as well as on-land participation in integrated methods for involving communities in the preservation of marine environments.
