Reefs die for many reasons: rising water temperatures, sewage, eutrophication, disease and negligence. A reef ecosystem that took hundreds of years to grow can be destroyed in a single afternoon by dredging, dynamite or cyanide fishing. Corals around the world have been severely affected by global warming. High temperatures cause corals to turn white (or "bleach"). If it remains too hot for too long, the corals die of heat shock.

There has been a recent surge of promotion selling "coral calcium pills". Selling ground up coral skeleton as a natural source of calcium is an endlessly recurring scam that hucksters pick up on every few years like clockwork. My colleague Wolf Hilbertz has a bottle of coral tablets someone was peddling in the 1960s. There are many natural sources of dietary calcium that don't require killing corals. It is important to keep a balance between your calcium and magnesium intake.

GCRA is a non-profit, all-volunteer, 501 (c)(3) corporation; donations to Global Coral Reef Alliance are fully tax-deductible. No salaries or board perks are ever taken out of any income raised-100% of funds raised goes directly to studying, building and restoring coral reefs around the world. If you would like to contribute to GCRA's program for saving reefs, please send your tax deductible contributions to:

There are huge discrepancies surrounding this issue. The harvesting is strictly supervised by the Japanese government.

If you want the ability to simply type the name of the group you are sending to, instead of choosing the group name from the address book, make sure to save the group in your frequent contacts list instead of your personal group. Groups saved in any list other than frequent contacts list must be selected from the address book. If you follow the instructions in [1.2] How do I create a personal group, the group will be in the Frequent Contacts folder.

Typically vessel sewage impacts manifest themselves in the form of excess nutrients and pathogens in the water column. In poorly flushed areas, such as bays and inlets, this results in excess macro-algae growth that will smother corals and impede their growth. It will also result in an excess of micro-algae or phytoplankton growth. These phytoplankton blooms may pose a health risk to humans while also being toxic to other species.

Over 200 square miles of near virgin reef can be found in Bermuda. The warm, nutrient rich waters of the Gulf Stream pass through Bermuda and have led to the formation of the worlds most northerly coral reef. The reef is very healthy, and has not suffered the effects of Diver Damage like some Caribbean locations. Abundant hard corals and sea fans are to be seen, but less sponges than you'll see in the Caribbean.

Artificial reefs are typically made from manmade materials like sunken ships, planes, cars, concrete, rubber tires and trash. On land, this material might be called junk. Although fish will hide behind or within any structure that provides shelter and although certain sponges and soft organisms will sometimes settle on these materials, they never turn into a true coral reef.

The working groups are made up of government and industry experts, each of which specializes in developing one of NextGen’s key capabilities. There are nine working groups dealing with the following subject areas: The working groups are comprised of expert teams whose work results in specific fact-based conclusions. The conclusions lead to recommendations that can be integrated into current NextGen development programs.

To power the mineral accretion process, a low DC voltage is necessary. The source of this current generally depends upon the environment near the reef. If a ready supply of electricity is available, cables can be attached to the structure. In more remote areas, solar collectors are usually the energy source. These panels will generally be set up on the shore to feed current to the Biorock reef via submerged cables.

Just as a gardener pulls up weeds that would overgrow the flowers, undesirable weedy organisms and certain sponges and algae that could overgrow corals are periodically removed. Organisms that kill corals, such as the crown of thorns starfish and certain coral-eating snails are eliminated. Biorock reefs also need to be periodically checked to ensure that cables and connections are intact.

There are many requests for mineral accretion projects from marine conservation groups around the world, but unfortunately there is little funding available from governments, international philanthropic agencies or private foundations. a result, most mineral accretion reefs are pilot projects that demonstrate the process. The results are so unexpectedly spectacular that one must see them directly to appreciate their value.

The time part is easy. Even if all I do is manage your books for you (billing, invoices, payments etc.), that’s probably several hours a week that’s now available. Now, imagine that instead of working on your books, or worse, spending days on your books at the end of the year, you were working ON your business. What if, from the extra time you spend ON your business, you get even one new client.

The Global Coral Reef Alliance is a 501(c)(3) non-profit organization dedicated to growing, protecting and managing the most threatened of all marine ecosystems-coral reefs. We primarily focus on coral reef restoration, marine diseases and other issues caused by global climate change, environmental stress and pollution.

Within days to weeks, as the mineral accretion grows around the attached coral fragments, corals begin to grow at accelerated rates. Their rapid growth is directly attributable to the electrical current in the underlying steel framework.

Global warming has caused significant reef mortality around the world. The prognosis is that oceans will continue to warm until world leaders recognize the long-term consequences of turning a blind eye to the problem. A few governments have tried to address the problem by building sea walls out of concrete, steel, coral rubble or sand bags. But these materials soon rust, corrode, collapse and need to be rebuilt.

Like an oasis in the desert, all forms of coral life are quickly attracted to Biorock reefs. Many forms of reef life have been observed to be attracted to the structures, and none repelled. However it is the organisms with limestone skeletons, such as corals, clams, oysters, barnacles, tube worms and sand-producing algae that are especially benefited, allowing them to outgrow weedy algae that often smothers and kills corals in polluted waters.

To date the EmerComms group is aware of only one instance of a direct link between AREN and a professional emergency organisation, although this is rapidly changing. The group has not forged links to date with professionals in other areas due to two stumbling blocks; one, the difficulty in obtaining adequate insurance cover and two, a perceived resistance to change by some members of those organisations.
