This research project involves professionals and researchers from the fields of archaeology, oceanography, meteorology, engineering and diving. The discovery of the ancient shipwreck, Chiang-Chun 1/sup st/, and the antiques load is of important historical significance. The whole research project includes the archaeology, seafloor mapping, and divers excavating and information system. The paper discusses the project in terms of seafloor mapping and information system. The purpose of seafloor mapping is, by the use of sonar inspection, to seek and spot the possible targets and to help the divers identify the targets. The facilities include a global positioning system, an echo sounder, a side scan sonar, and a sub-bottom profiler. After an arduous investigation of 28 possible targets in a six-square kilometer area under rough sea status, three targets were identified to be Chiang-Chun 1/sup st/, an iron-shell-ship, and a ship-shaped reef. The Penghu undersea archeology project and the general information on the undersea archeology survey and salvage technology were introduced on a web site for an easy access. The structure and the method used to set up the web site are introduced. The contents of the web site include project history, project introduction and execution, undersea archeology technology, shipwreck excavation, perspective of undersea archeology, messages box, full contents search, and linkages to other underwater archeology sites.","PeriodicalId":397110,"journal":{"name":"Proceedings of the 2000 International Symposium on Underwater Technology (Cat.

This type of source, however, also excites strong compressional waves in the water and sediment, and so the generated interface wave is affected by this compressional wave, resulting in difficulty in processing. The waves generated in this way are also poor in duality and those sources may cause environmental problems. To solve this, we tried to utilize an electromagnetic induction source, called Boomer, which is generally used in the water as a source for generating compressional waves. First, we fabricated a Boomer with several types of vibrator plates on a small scale. To evaluate the performance of the source, the sound pressure level exited by the source was measured in a water tank and was compared with a designed one. Then we drove the source with the vibrator plates on the seafloor and evaluated the properties of the generated interface wave, which observed by a geophone, and compared the measured wave signal with one generated by dropping a weight. Consequently, the electromagnetic induction source turns out to be useful for generating an interface wave having repeatability.","PeriodicalId":397110,"journal":{"name":"Proceedings of the 2000 International Symposium on Underwater Technology (Cat.
