Effects of hydrocarbon spills on the temperature and moistureregimes of Cryosols in the Ross Sea region

[摘要] Hydrocarbon spills have occurred on Antarctic soils where fuel oils are utilized, moved or stored.We investigated the effects of hydrocarbon spills on soil temperature and moisture regimes by comparing theproperties of existing oil contaminated sites with those of nearby, uncontaminated, control sites at ScottBase, the old Marble Point camp, and Bull Pass in the Wright Valley. Hydrocarbon levels were elevated infuel-contaminated samples. Climate stations were installed at all three locations in both contaminated andcontrol sites. In summer at Scott Base and Marble Point the mean weekly maximum near surface (2 cm and5 cm depth) soil temperatures were warmer (P
