Determining the nature, evolution, and impact of acid-generating sulfur deposits in the Mary Rose wooden hull is crucial for protecting Henry VIII's famous warship for generations to come. Here, a comprehensive X-ray absorption near-edge spectroscopy (XANES) and X-ray fluorescence (XRF) study sheds vital light on the evolution of complex sulfur-based compounds lodged in Mary Rose timbers as a function of drying time. Combining insights from infrared spectroscopy correlates the presence of oxidized sulfur species with increased wood degradation via the loss of major wood components (holocellulose). Intriguingly, zinc is found to co-exist with iron and sulfur in the most degraded wood regions, indicating its potential contributing role to wood degradation. This study provides crucial information on the degradation processes and resulting products within the wood, which can be used to develop remediation strategies to save the Mary Rose.
确定玛丽·罗斯号木质船体中产生酸的硫沉积物的性质、演变和影响对于保护亨利八世著名的战舰至关重要，使其在未来数代都能得以保存。在这里，一项全面的 X 射线吸收近边光谱（XANES）和 X 射线荧光（XRF）研究揭示了作为干燥时间函数而驻留在玛丽·罗斯木材中的复杂基于硫化合物的演变。通过与红外光谱相结合的研究，将氧化硫物种的存在与通过主要木材成分（全纤维素）的损失导致的木材降解相关联。有趣的是，锌被发现与铁和硫一起存在于最降解的木材区域，这表明它可能对木材降解有贡献。本研究提供了木材内降解过程和产生的产物的关键信息，可用于开发修复策略来拯救玛丽·罗斯号。
