...Atmospheric Administration, or NOAA, describes the definition of an artificial reef as “a manmade structure that may mimic some of the characteristics of a natural reef.” (NOAA) Humans have been creating these artificial reefs since the 1830s, when fishermen would strategically place logs in the water in order to form a habitat in which they could increase the amount of fish they could catch. These manmade structures could be constructed out of any object that can sink, including tires, decommissioned subway cars, old automobiles, oil drilling rigs, shopping carts, old refrigerators, and old vending machines to name a few. (NG) Bridges and lighthouses also provide artificial reefs in many areas. (NOAA) If the objects are smaller and not as heavy, the foundations must be created in order to hold these objects in place in...

...Coral reefs occupy only 0.2% of the ocean floor, yet they are the most biologically diverse marine ecosystems known today, and support over 25% of all marine organisms (Yip). Due to the massive amount of marine species that populate coral reef habitats, maintaining healthy reefs is crucial for the continuation of marine biodiversity. In past years, the increase of mortality rates in coral has been caused by a number of factors, including wide-spread stress and disease. In the Indo-Pacific, coral reefs have been declining at a rate of approximately 2% per year for the last 20 years (Yip). Coral reef fish biodiversity is crucial for the sustainability of the coral reef ecosystem, as well as for the ability of the coral reefs to provide services...

...The Rigs to Reef Program commenced in September of 2012 and is managed by Federal and State agencies. In the United States, Texas, Louisiana, Mississippi, and California approved detailed legislation to establish programs assisting in the construction of artificial reefs from oil and gas platforms (“Decommissioning and Rigs to Reefs…”). Marine life struggles to develop a habitat on the flat bottom floor in the Gulf of Mexico; however, with these “Towers of Life” in our gulf waters, sea life is now healthier than ever. Not only does this program benefit oil companies, but also allows coastal communities to flourish. Fishermen are reaping the benefits due to the drastic increase of the fish population around these sites. An experienced deep-sea...

Numerous amounts of studies have been made and scientists have found increases in fish count and recruiting to gas and oil platforms and other artificial arrangements. Around these reefs, catch rates are higher. “For oil and gas platforms, off the coast of California, scientists have suggested that both, the upper depths and deeper structures may be very important to certain species in different life stages, with the platforms being used as both recruitment habitat for juvenile fish and also refuge areas for adult fish” (Ajemian 2). These arrangements...

...Coral Reef Restoration Techniques in Florida Angel Fisch OCE1001 MW 9:30 am Palm Beach State College March, 2010 ABSTRACT An estimated 20% of the world’s coral reefs have been effectively destroyed and show no immediate prospects of recovery. In addition, 24% of reefs are under risk of collapse from human pressures and another 26% are under a long-term threat of collapse (Wilkinson, 2004). Therefore, preservation and restoration of coral reefs is of particular local, national and global interest. Although corals may have the ability to recover from natural disturbances, stresses from human activities coupled with natural stresses may inhibit their ability to recover (Edwards and Gomez, 2007). Restoring damaged and disturbed reefs may facilitate recovery and help compensate for reef destruction. This paper reviews coral reef restoration techniques and selected case studies at locations around the world. Some of the successes and potential issues of reef restoration projects are discussed along with considerations and implications for coral reef managers. INTRODUCTION Coral reefs, one of the oldest ecosystems on Earth, are highly complex and often called “rainforests of the sea” because of the diversity of life forms they support (Connell, 1978; Secord, 2001). Coral reefs are important both economically and ecologically. It is estimated that they provide US$375 billion per year around the world in goods and services, with approximately 500 million people dependent...

...Coral Reef Mitigation Plan XXXXXXXXXXXXXXXX SCI/275 October 9, 2011 XXXXXXXXXXXXX Coral Reef Mitigation Plan A recent report estimates that 27% of the world's reefs are already gone and severely damaged and that another 58% are degraded and threatened. Here in the United States, in faraway places, and in the planet’s most secluded areas are experiencing coral reef crisis. Coral reefs survival are endangered from a controlling mixture of stresses which include global warming, bleaching, carbon dioxide, water pollution, sedimentation, coastal development, damaging fishing practices, coral mining, tourism, and ozone depletion. Threatening behavior from human activities, either direct or indirect, create considerable hazards to coral reef ecosystems, and the human populations that rely on them. Ocean warming caused from global warming and ozone depletion is severely hazardous to coral reefs. Coral organisms are extremely receptive to temperature changes. Water temperature increase may cause mass bleaching among coral reefs which causes coral polyps to expel zooxanthellae from the stress caused by ultraviolet radiation or heat. Zooxanthellae supplies reef corals with up to 80% of its energy, making zooxanthellae necessary for coral survival (Coral Reef Alliance, 2010). Zooxanthellae provide color for corals so when released corals become white or bleached. Coral have a chance to recover from bleaching effect only if normal conditions return promptly enough, but in most...

...201-140-3A-06 Coral Reefs are located in tropical oceans near the equator. The largest coral reef is the Great Barrier Reef in Australia The second largest coral reef can be found off the coast of Belize. In Central America. Other reefs are found in other areas in tropical oceans. Corals can exist as individuals polpys, or in colonies and communities that contain hundreds to hundreds of thousands of polyps. For example, brain corals are some of the most recognizable coral species. These corals are colonies of many individual polyps, the individual polyps average 1-3mm in diameter. The physical structure of a coral reef is built by reef building polyps. When they secrete calcium carbonate skeletons, they create a complex three dimensional framework upon which an abundance of coral species and other marine plants and animals may live. About 25 % of all marine life is found in coral reefs, including around two million species of fish, crustaceans, sponges and seaweeds. Together these plants and animals form the coral reef ecosystem. As well as supporting marine biodiversity, reef ecosystems provide a number of ecological services and goods to human populations on a local, regional, and national level as they play an important role in coastline and habitat protection, nitrogen fixing, sand supply, climate records, fisheries, medicine, recreation and tourism. Coral reef frameworks can serve as physical buffers for ocean waves and currents. As waves pass over a reef structure, their...

...Marine conservation From Wikipedia, the free encyclopedia Coral reefs have a great amount of biodiversity. Marine conservation, also known as marine resources conservation, is the protection and preservation of ecosystems in oceans and seas. Marine conservation focuses on limiting human-caused damage to marine ecosystems, and on restoring damaged marine ecosystems. Marine conservation also focuses on preserving vulnerable marine species. Contents 1 Overview 2 Coral reefs 3 Human impact 4 Techniques 5 Technology and halfway technology 6 Laws and treaties 7 Organizations and education 8 References 8.1 Notes 8.2 Bibliography 9 External links Overview Marine conservation is the study of conserving physical and biological marine resources and ecosystem functions. This is a relatively new discipline. Marine conservationists rely on a combination of scientific principles derived from marine biology, oceanography, and fisheries science, as well as on human factors such as demand for marine resources and marine law, economics and policy in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation can be seen as subdiscipline of conservation biology. Coral reefs Coral reefs are the epicenter for immense amounts of biodiversity, and are a key player in the survival of an entire ecosystem. They provide various marine animals with food, protection, and shelter which...

It renowned for it visibility from space considering it holds more than 2900 individual reefs and is home to over ‘6 300’ different species (wwf). Although this ecosystem is protected as a World Heritage site, it has still been significantly impacted by human activities, including pollution, mining and urban run off. Traditional management strategies have been a vast help over the past thousands of year but the severity of human impacts have dramatically increased in the past 50 years and contemporary strategies have been put into practise in attempt to reduce these. While the Great Barrier Reef stands as a beautiful testament to the power of natural construction, in recent years there have emerged numerous threats to the existence of the reef that loom and make its future fairly uncertain which is mainly due to the influence of man. Global warming is caused by the increase in greenhouse gases in the atmosphere which...

...Coral reefs form some of the most diverse ecosystems on earth. They occupy less than 1% of the worlds ocean surface, about half the area of France, yet they provide a home for 25% of all marine species, including fishes, molluscs, echinoderms and sponges. They are most commonly found at shallow depths in tropical waters, particularly in the Pacific Ocean. Coral reefs deliver ecosystem services to tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at $375 billion. It is believed to have emerged more than 540 million years ago. New species originate 50% faster in coral reefs than in any other habitats. The fossil records show that reefs have been remarkably successful in surviving through large environmental disturbances. However the combination of drastic environmental changes that we're seeing today, such as degraded water quality, depleted fish stocks, coral bleaching, ocean acidification and loss of habitat causes them to be under great threat. Coral reefs are perhaps one of the greatest but, least known of wonders of our world. There are three different kinds of coral reefs. There are fringing, barrier, and atoll. Fringing reefs are attached to margins of an island or continent, rough, table like surface, as much as 1 kilometer wide. On their seaward side they slope steeply to the ocean floor. Fringing reefs grow in shallow water near the shore and prefer dry climates with limited river runoff. There are...
