A French biologist who moved in Surrealist circles, Jean Painlevé began making films about underwater creatures in 1927, and by 1982 had created over two hundred films on a broad range of natural, scientific, and political subjects. His underwater films remain the most ethereal and poetic works in his oeuvre, and he specifically used cinema to capture the mystery and wonder of nature.

Natural coral reefs are in a state of serious decline worldwide. The pressures of over fishing, recreational activities, environmental pollutants, and global warming have stressed these marine ecosystems to the breaking point. One of the oldest methods of augmenting natural reef systems is the implementation of artificial reefs. These projects are not as simple as dumping waste or scrap materials in offshore areas. Proper material selection is vital to produce a healthy artificial marine habitat that is completed on schedule and on budget. This Capstone Project will evaluate the most commonly used materials and provide a comparison of their strengths and weaknesses. This comparison provides a valuable tool for project managers as they begin the reef planning process.
