Sulfur Accumulation in the Timbers of King Henry VIII’s Warship Mary Rose: A Pathway in the Sulfur Cycle of Conservation Concern
2005 (English)In: Proceedings of the National Academy of Sciences of the United States of America, PNAS, ISSN 0027-8424, Vol. 102, no 40, 14165-14170 p.Article in journal (Refereed) Published
In marine-archaeological oak timbers of the Mary Rose large amounts of reduced sulfur compounds abound in lignin-rich parts such as the middle lamella between the cell walls, mostly as thiols and disulfides, whereas iron sulfides and elemental sulfur occur in separate particles. Synchrotron-based x-ray microspectroscopy was used to reveal this environmentally significant accumulation of organosulfur compounds in waterlogged wood. The total concentration of sulfur in reduced forms is ≈1 mass % throughout the timbers, whereas iron fluctuates up to several mass %. Conservation methods are being developed aiming to control acid-forming oxidation processes by removing the reactive iron sulfides and stabilizing the organosulfur compounds.
