Percentage of Carbon and Nitrogen of Soil Sediments from the Shark River Slough, Taylor Slough and Florida Bay within Everglades National Park (FCE LTER), Florida, USA, August 2008 - ongoing

These data represent the results of CHN Analysis from annual soil sampling from all 17 FCE LTER transect locations from Year 2008 thru ongoing. In 2017, the samples were collected before Hurricane Irma (2017a) and post Hurricane Irma (2017b). Surface soils from 0-10 cm been homogenized and analyzed from Sawgrass and mangrove sites and Florida Bay sites. Soils and sediments were analyzed for percentage by weight of total Carbon and Nitrogen with a PerkinElmer CHNS /O 2400 Series II Elemental Analyzer. These analyses are completed to document the differences in soil composition among transect sites, and to provide a baseline dataset against which long-term changes in the properties of the soils can be detected.

本数据集涵盖2008年至今对全部17个FCE LTER样带点位开展年度土壤采样所得到的碳氢氮元素分析（CHN Analysis）结果。2017年的采样分为两组，分别在厄玛飓风（Hurricane Irma）发生前（2017a组）及发生后（2017b组）进行。针对锯齿草（Sawgrass）群落、红树林群落及佛罗里达湾（Florida Bay）点位的0-10 cm表层土壤，均完成了均质化处理与分析。使用珀金埃尔默（PerkinElmer）CHNS/O 2400系列II型元素分析仪，对土壤及沉积物样品的总碳、总氮质量百分比进行了测定。开展本次分析的目的在于阐明不同样带点位间土壤组成的差异，并构建基准数据集，以便后续检测土壤属性的长期变化。
