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质沉船的影响

摘要对密克罗尼西亚联邦丘克泻湖（Chuuk Lagoon）发生的十二次第二次世界大战铁沉船的腐蚀微环境进行了研究，以查看是否因最近的一次重大台风引起了可测量的变化。使用七个先前检查过的沉船地点进行校准，以评估对环境的影响。五种新的沉船，包括日本帝国海军的一艘驱逐舰Fumitzuki，被评估的深度是以前研究的两倍。新数据表明腐蚀速率的对数随深度下降至36 m呈线性关系。腐蚀电位，固结厚度和pH值的测量表明，在2015年4月的台风Maysak期间，许多容器都发生了部分减量，腐烂率随之增加。
