Abstract

Abstract The corrosion microenvironment of a dozen Second World War iron shipwrecks in Chuuk Lagoon, Federated States of Micronesia, was investigated to see if there were any measurable changes caused by a recent major typhoon. Seven previously inspected wreck sites were used for calibration to assess the environmental impacts. Five new wrecks, including the Fumitzuki, a destroyer of the Imperial Japanese Navy, were assessed at up to twice the depth of previous studies. The new data showed that the logarithm of the corrosion rate falls linearly with depth to 36 m. Measurements of corrosion potentials, concretion thickness and pH showed that many of the vessels suffered partial deconcretion during the typhoon Maysak in April 2015 with concomitant increases in the rate of decay. Regrowth of the colonising marine organisms are presently ameliorating the impact of the typhoon.

通过腐蚀微环境的变化评估台风对楚克泻湖历史铁沉船的影响

摘要对密克罗尼西亚联邦楚克泻湖十几艘第二次世界大战铁船的腐蚀微环境进行了调查，以了解最近的一次大台风是否造成了任何可测量的变化。七个先前检查过的沉船地点被用于校准，以评估环境影响。五艘新的沉船，包括日本帝国海军的驱逐舰Fumitzuki，被评估的深度是之前研究的两倍。新数据显示，腐蚀速率的对数随着深度的增加而线性下降至36米。对腐蚀电位、结核厚度和pH值的测量表明，在2015年4月的台风“梅萨克”期间，许多船只出现了部分去腐蚀，同时腐蚀速率也随之增加。定居海洋生物的重新繁殖目前正在减轻台风的影响。

期刊介绍： The journal Conservation and Management of Archaeological Sites (CMAS) has established itself as the primary reference in this field, both for active professionals and for university teachers and students. Launched in 1995, it is the only journal that covers both theoretical and practical issues in heritage site management and conservation. Peer-reviewed papers from around the world report on new thinking and best practice in site management and conservation. Topics covered include: •Cultural, social, ethical and theoretical issues in archaeological site management and conservation •Site management •Historical documentation and condition reporting •Site deterioration and environmental monitoring •Preventative conservation, including reburial and protective sheltering of sites •Building materials analysis and treatment •Restoration and reconstruction of buildings •Visitor management and sustainable tourism •Site interpretation •National and international legislation and charters
