To deposit clean cement rubble created by the12 Jan 10 earthquake at a designated site(s)intending to create new marine life habitat; anartificial reef, in greater Port au Prince Harbor.
For the past 17 years, the University of Florida has built & placed 26-miles of concrete artificial reefs in the Gulf of Mexico to study impact on grouper, a popular food fish.
Location Survey Checklist1. Away from navigation channels;2. At a depth approximately 30 to 90 feet;3. Away from live corals (at least one mile);4. Away from areas where sedimentation will occur;5. In areas of enriched nutrient tidal flow and current;6. At a height approximately one-third the water column;7. On a flat, hard-packed or silt bottom away from active growth.
A diver inspects an artificial reef made of about4,000 concrete blocks at Loch Linnhe, the Isle ofLismore, Scotland. At depths between 30 to 90 feet,it created by the Scottish Association for MarineScience to study man-made structures as habitat.
