    The oceans are currently oversaturated with respect to calcium carbonate minerals, but some researchers became fearful that a falling pH could lower the supply of carbonate ions, and eventually drive the ocean’s saturation point so low that calcium carbonate minerals will dissolve faster than they form.

    During the winter, the temperature at the bottom can be 4° C while the top is 0° C (ice). This image helps to show how CO2 reacts with the water, taking up the precious carbonate building blocks the coral need to survive. (Image from NOAA) And if the increasing acidity wasn’t enough, the rising temperatures also play a factor in coral survival. Review with students the vocabulary terms vertebrate and invertebrate.

    Many passionate and dedicated people like marine scientists, conservationists, and policy-makers are refusing to give up on the future health of our oceans, and so hope remains. This site contains lesson plans that include activities related to ocean geography, pollution, products of the sea, and marine ecosystems. The USCRTF now has a roadmap to increase understanding about coral reefs and better protect them from further destruction, embodied in the National Action Plan to Conserve Coral Reefs.

    However, they protect more than 150 000 kilometers of coastline in more than 100 countries and territories. Reefs themselves grow even more slowly because after the corals die, they break into smaller pieces and become compacted. Dr Andrew Baird of the ARC Centre of Excellence for Coral Reef Studies and James Cook Universities was quoted as saying, It is certainly the worst coral die-off we have seen since 1998. In industrial wastewater and farming runoff, there are always chemical compounds which can make zooxanthellae toxic to corals as well as in the case of oil spills.

    Initiated by the Commonwealth Science Council, the South Pacific Coastal Zone Management Program provides training in coastal zone management and develops capacities to assess resources and monitor change. Both rates of decline have subsequently been documented in numerous other studies as an on-going trend. But there is growing evidence that 450 ppm (which is likely to result in an average global temperature around 2 degrees warmer than the pre-industrial period) may result in unacceptable change and risks to natural and human systems.

    Science (301): 929-933 [13] North, Gerald R. 1975. In addition, fish feeding causes health problems for the fed animals and disrupts the natural processes within the marine community. Certain fishing techniques, meanwhile, are especially harmful: fishermen using dynamite, cyanide, bleach, and other destructive methods destroyed about half of the coral reefs in the Indo-Pacific region during the 1980s and 1990s. Sharks, groupers, and other predatory fish keep populations of smaller fish and other organisms in balance.

    Up to 90% of a coral’s nutrients are obtained from the algae. Many types of epiphytes ("air plants") and ferns can be found here as well. Coral reefs have been increasingly damaged by warming temperatures and rising seas, thanks to climate change. Talk about how fishing technology has improved through the centuries in OCEAN HARVEST. 5.3 Visit a local fish market and identify fish that can be purchased for human consumption in FISHY BUSINESS. 5.4 Determine sustainable yields for a population of fish through a simulation activity called THE TOO MUCH GAME. 5.5 Discover that coral reefs are homes to many organisms and how to protect and conserve coral reefs in WHERE’S MY HOME, WHERE’S MY FOOD.

    If zooxanthellae aren’t producing food then the coral reefs become starved and this is just another stressor that is put on them. For example, scientists from all over the world work together on the Intergovernmental Panel on Climate Change (IPCC) to generate models that reflect different rates of population growth, economic growth, technology application, and social change.

    This interferes with the way that corals produce calcium carbonate, and it becomes difficult to build reefs. Found around coastlines in the tropics, coral reefs provide homes for about a third of all fish species on Earth and numerous other marine organisms. Review with students the vocabulary terms vertebrate and invertebrate. As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided.
