  • A New Technology for Artificial Reef Construction in Coastal Ecosystems
    A New Technology for Artificial Reef Construction in Coastal Ecosystems Cynthia Warzecha Reef ecosystems have suffered from a variety of anthropogenic stresses during the past several decades. Offshore recreational activities, siltation, sewage discharge, excessive nutrient input, thermal pollution, (Rinkevich 1995) and overfishing (Luoma 1996) have contributed to the declining health of many reefs. Divers, snorkelers, and boat and cruise ship anchors can physically damage corals by breaking them, abrading large coral forms, and burying coral fragments in sediment (Rinkevich 1995). Overfishing of algae-eating fish can lead to accelerated algae growth that in turn smothers corals (Luoma 1996). Anthropogenic stresses have contributed to the loss of ten percent of the world's coral reefs and an additional two-thirds are at risk of serious decline (Luoma 1996). Zoologist Marjorie Reakea-Kudla (1996) predicts the loss of seventy percent of the world's coral reefs by the year 2036. Various techniques have been employed to create habitats for reef-dwelling organisms. In United States coastal waters, most efforts have focused on increasing fish populations to provide enhanced experiences for recreational fishing and sport-diving (Hutchings 1996). Activities such as the deliberate sinking of ships or oil drilling platforms successfully attract fish. However, it is unclear whether these structures provide suitable habitat for reproduction or just enhance the local population by attracting fish from other areas (Weisburd 1986). New techniques have begun to focus on the restoration of coral reef ecosystems. Of all marine ecosystems, coral reefs are the most diverse and complex. The building blocks of the reef are symbiotic animals that rely on specialized algae called zooxanthelae for nutrients.

  • Reef Re-Creation Novel Restoration Strategies for the Osborne Tire Reef
    Reef Re-creation Novel Restoration Strategies for the Osborne Tire Reef By Robert Cabral Robert Primeau A project submitted in partial fulfillment of the requirements for the degree of Master of Landscape Architecture at the University of Michigan Faculty Advisors: Kathy Velikov, University of Michigan Robert Grese, University of Michigan Professional Advisor and Client: Hannes Bend Abstract In the early 1970s a failed effort at creating Osborne Reef, an artificial fishery, resulted in the release of two million tires into the Atlantic Ocean outside Fort Lauderdale, Florida, further endangering already threatened coral reef habitat. The tires blanket habitat areas and travel with ocean and storm currents, impacting delicate coral structures along the way. Efforts to remove the tires have proven inadequate at addressing this ecological threat. Through interviews and academic research we have studied the history and practice of artificial reef construction in general, and the Osborne Reef in particular. Proposed are a series of interventions created using parametric modelling techniques designed for three roles. First, they will neutralize the threat caused by the tires either by encapulating them under or accreting them along its structure. Second, they will mitigate tire-associated damage and loss and serving as a medium for coral and marine organism growth. Third, it will serve as a laboratory for novel marine ecological restoration techniques as a jointly managed public- private partnership. ii Acknowledgements Thanks goes to our faculty advisors, Kathy Velikov and Robert Grese, for guiding us through the long process of forming a project, for supplying sage guidance, illuminating suggestions, and an attitude of encouragment.
