Remote-sensing methods, using electromagnetic radiation detected by airborne and spaceborne instruments, have the potential to revolutionise the investigation of oil contamination in high latitudes. Spaceborne monitoring, in particular, offers many advantages, including: obtaining data from relatively inaccessible areas; day and night, all-weather observations; regular monitoring opportunities; spatial resolution of 20 m or better; and areal coverage of 30,000 square kilometres or more. Calibrated, spatially registered data can be readily integrated into geographic information systems for evaluation and prediction of spill behaviour. However, very little investigation of this potential has yet been undertaken. This paper reviews the possibilities for monitoring soil characteristics, including thermal regime, the presence of contamination, and long-term consequences of spills, for topography, hydrology, and vegetation cover.
