The explorers of Antarctica's heroic era erected buildings and brought large amounts of supplies to survive the extreme environment during their Antarctic exploration. Huts built by Robert F. Scott and Ernest Shackleton during the early 1900's were abandoned once the expedition was over, leaving the huts and thousands of artifacts behind. The extreme polar environment has protected many of the artifacts from rapid decay but over the past nine decades, serious deterioration has become apparent. Results obtained through preliminary studies indicate that unique wood destroying fungi are decaying wood in the contact with the ground and various molds and cellulose degrading fungi are attacking artifacts made of leather, textiles and other organic materials. Exterior woods are also being deteriorated by non-biological deterioration processes including salt, ultraviolet radiation and wind erosion. Chemical damage within the huts and soils contaminated with aromatic hydrocarbons from petroleum products have also been found. This project will identify the biological and non-biological agents responsible for causing the deterioration, study mechanisms and progressive sequence of events taking place during decay processes, test methods to be used to control future deterioration, determine the extent of environmental pollutants in soils at the historic site, and evaluate chemical spills within the huts. The research will provide the scientific data required by conservators to help protect these important historic site for future generations. It will also add to the knowledge of the biology of Antarctic microorganisms, the biodiversity of microbes present in this unusual environment, and elucidate unique deterioration processes.

南极英雄时代的探险家们在南极探险期间，为了在极端的环境中生存，他们建造了建筑物，并带来了大量的物资。由罗伯特·F。斯科特和欧内斯特·沙克尔顿在20世纪初的探险结束后被遗弃，留下了小屋和数千件文物。极端的极地环境保护了许多文物免受快速腐烂，但在过去的九十年里，严重的恶化变得明显。通过初步研究获得的结果表明，独特的木材破坏真菌是与地面接触的腐烂木材，各种霉菌和纤维素降解真菌正在攻击皮革，纺织品和其他有机材料制成的文物。室外的树木也因非生物的退化过程而退化，包括盐、紫外线辐射和风蚀。该项目将确定造成退化的生物和非生物因素，研究在退化过程中发生的事件的机制和渐进顺序，用于控制未来退化的测试方法，确定历史遗址土壤中环境污染物的程度，并评估小屋内的化学品泄漏情况这项研究将为保护人员提供所需的科学数据，以帮助为后代保护这些重要的历史遗址。它还将增加南极微生物的生物学知识，这种不寻常的环境中存在的微生物的生物多样性，并阐明独特的退化过程。
