Physical and Chemical Characteristics of Soil Sediments from the Shark River Slough and Taylor Slough, Everglades National Park (FCE LTER), Florida, USA, August 2004 - ongoing

These data represent the results of annual soil sampling and analysis from all 17 FCE LTER transect locations from Year 2004 thru ongoing. Surface soils from 0-10 cm have been homogenized and analyzed from Sawgrass and mangrove sites and Florida Bay sites. Soils and sediments were analyzed for a suite of physical/chemical variables, including bulk density, organic matter content, extractable iron, AVS and CRS sulfur, and various forms of extractable phosphorus. These analyses are completed to document the differences in soil structure among transect sites, and to provide a baseline dataset against which long-term changes in the physical/chemical properties of the soils can be detected.

本数据集涵盖2004年至今对全部17个FCE LTER样带点位开展的年度土壤采样与分析结果。研究人员对锯草（Sawgrass）样地、红树林样地及佛罗里达湾样地的0-10 cm表层土壤进行均质化处理后开展分析。针对土壤与沉积物检测了一系列理化指标，包括容重、有机质含量、可提取态铁、酸挥发性硫化物（AVS）与铬还原态硫化物（CRS），以及多种形态的可提取态磷。本系列分析旨在阐明各样带点位间的土壤结构差异，并构建基准数据集，借此可检测土壤理化性质的长期变化。
