Add a definition This suggests that the hydrocarbon contamination did not reach deeply beyond theactivelayer, so that most contaminated sites were, in fact, shallow. From theCambridge English Corpus Theactivelayeris generally 30- 40 cm thick. From theCambridge English Corpus The column was subjected to several cycles of top-down freezing and thawing to simulate anactivelayer. From theCambridge English Corpus These were finer than the original sediments that form the top of theactivelayer(sandy gravel). From theCambridge English Corpus Together, equations 14 and 18 allow the value of the thickness of theactivelayer() to be determined. From theCambridge English Corpus The sites where theactivelayerhad been disturbed were stable several years after the initial disturbance. From theCambridge English Corpus In these locations, theactivelayerwater content is very low, sometimes averaging less than 1% through the entire soil profile. From theCambridge English Corpus At the same time, this is compensated for by the fact that the biomass in theactivelayerwill grow more rapidly. From theCambridge English Corpus Curves 1,2-heat sources confined only to theactivelayer. From theCambridge English Corpus In most cases fuel had been contained in the upper part of theactivelayer. From theCambridge English Corpus There were no significant differences between the depth of theactivelayerin disturbed and undisturbed sites. From theCambridge English Corpus In 1996 the sediment moisture content around these cracks was, on average, about double that elsewhere in theactivelayer. From theCambridge English Corpus Theactivelayerdepth is about 35 cm, and the permafrost in the area is dry-frozen. From theCambridge English Corpus As the freeze-front moves down through theactivelayer, the lower part of the unfrozen zone becomes isothermal near the freezing temperature. From theCambridge English Corpus The 1992 remedial action removed the top of theactivelayer, that is, the most contaminated sediments, and replaced them with clean backfill. From theCambridge English Corpus The pattern of contamination identified prior to remedial action was generally of a higher concentration of hydrocarbons in the surface of theactivelayer, decreasing in depth. From theCambridge English Corpus Soil excavation can be complicated by permafrost, which melts when the contaminatedactivelayeris removed. From theCambridge English Corpus Low impact, low technology remedial action applied at some sites removed a significant percentage of fuel in theactivelayer, thus reducing the potential for secondary effects.
