Characterization of burned and unburned moist acidic tundra soils for estimating C and N loss from the 2007 Anaktuvuk River Fire, sampled in 2008.

This file contains the soil profile data for burned and unburned moist acidic tundra sites used to estimate C and N loss from the Anaktuvuk River Fire (2007). These sites were sampled in summer of 2008. Unburned sites were used to develop a method for estimating soil organic layer depth and plant biomass, and for determining the characteristics of unburned soil organic layers. In burned sites, we characterized residual organic soils and used biometric measurements of tussocks to reconstruct pre-fire soil organic layer depth. Together, these measurements were used to reconstruct pre-fire soil and plant carbon and nitrogen pools and estimate ecosystem losses of these elements during the fire.

本数据集包含用于估算2007年阿纳克图沃克河火灾（Anaktuvuk River Fire）中碳（C）、氮（N）流失量的火烧与未火烧湿润酸性冻原样地的土壤剖面数据。上述样地于2008年夏季完成采样。未火烧样地被用于构建土壤有机层厚度与植物生物量的估算方法，并用以明确未火烧土壤有机层的特征。在火烧样地中，研究人员对残留有机土壤进行了特征表征，并通过草丘的生物测量数据重建了火灾前的土壤有机层厚度。综合上述测量结果，研究人员得以还原火灾前土壤与植物的碳氮库，并估算出此次火灾期间该生态系统中这些元素的流失量。
