Sustainable Development Goals
Abstract/Objectives
Scientific Analysis of Marine Archaeological Artifacts Scientific analysis is conducted on artifacts discovered from both terrestrial and underwater marine archaeological sites, utilizing modern technology to further understand their origins, manufacturing techniques, preservation conditions, and maintenance requirements. The specific research topics include material composition analysis, manufacturing processes, deterioration assessment, and preservation environment evaluation for artifacts such as metalware and ceramics. During the research process, team members can learn how technology and humanities integrate across disciplines. This interdisciplinary collaboration not only promotes the physical sustainability of cultural relics but also establishes a comprehensive research and conservation system, providing the most appropriate protection solutions for cultural heritage.
Results/Contributions
  • Scientific Analysis of Marine Archaeological Artifacts

Ellen Hsieh collaborated with Tung-Ho Chen from the National Palace Museum using multiple detection techniques for analyzing the cross found on Heping Island. They utilized X-ray Fluorescence to analyze the chemical composition and X-ray Diffraction to identify metal alloys and corrosion products. Additionally, a 3D optical microscope and X-ray computed tomography were employed to examine the structure of the object. The cross-analysis confirmed that this metal artifact is a heterogeneous object, providing valuable insights into its production techniques and offering a reference for future conservation and restoration efforts.

Moreover, Hsieh identified fragments of Anping jars for the first time among ceramics excavated in Acapulco, Mexico. Invited by underwater archaeologist Roberto Junco, she is contributing an article on this discovery. Meanwhile, she is launching two scientific studies on Anping jars:

1. Comparative scientific analysis on early and late Anping jars using materials excavated from Heping Island and Fort Provintia (In collaboration with Liu Ting-Yo from the Tainan Archaeology Center and Yang Ziyi from Imperial College London). 

2. 3D scanning and multivariate morphometric analysis of Anping jars recovered from Taiwan’s waters.
