Taiwan is surrounded by ocean, we expect through the underwater survey could make us know more about the marine resources, history and culture and understand how to use the natural resource well. The
purpose of this paper is to investigate the survey strategy for marine archaeology using modern underwater survey and identification instruments and techniques on Peng-Hu underwater cultural site
survey. The survey process can be roughly divided into three stages, preliminary and comprehensive survey (PCS), double-check and localization survey (DLS), and precise and identification survey
(PIS) respectively. The objective of PCS is not to miss any possible target. The major equipments of the underwater engineering including marine magnetometer, the subbottom profiler, and the side-scan sonar are deployed simultaneously. After the comparisons and analysis of the images from various instruments obtained from PCS and DLS, the PIS will obtain the direct photo viewing of the targets using
remotely-operated vehicle (ROV) or divers. This strategy has been conducted firstly in Kaohsiung Sizihwan bay Marine Test Field and
Kaohsiung Cross-Harbor Tunnels as the preliminary. Then move to Peng-Hu Sea Area for the underwater archaeology survey which is authorized by Acdemia Sinica from April 2008 to June 2009. From the
result, the megnetometer can help sonar to identify the target more specifically, especially for the sediment. It brings better result than side-scan sonar and multi-beam echo sounder which can only search the target on seabed and can search broader area than
subbottom profiler. Therefor, magnetomator is an essential equipment for underwater archology.
