Water, Soil, Floc, Plant Total Phosphorus, Total Carbon, and Bulk Density data (FCE) from Everglades Protection Area (EPA) from 2004 to 2016

These data are a compillation of data from multiple sources including South Florida Water Management District (SFWMD) DBhydro web database, United States Environment Protection Agency Regional, Environmental Monitoring and Assessment (REMAP), Everglades Soil Mapping (ESM), and Florida Coastal Everglades Long Term Ecological Research (FCE-LTER). The matrix of these data were compiled for soil, surface water, floc, and plants where the nutrients are counted for total phosphorus, total carbon, and bulk density. When downloading the data from DBhydro, only regularly collected samples (SAMP) were included these data. As per DBhydro metadata, the regular samples were collected monthly by grab method throughout the year from 2004 to 2016 for SFWMD monitoring stations across the EPA. All flagged and field quality controlled values were excluded to avoid the duplication of data. In order to maintain the quality assurance/ quality control (QA/QC) the method detection limit for water TP was fixed at 2 µg/L by the SFWMD. This data set were used to assess the decadal trend of TP concentration in surface water and soil in EPA. Available data from 2004 to 2014 was collected for soils and from 2004 to 2016 for water to understand a decade of trends. Both Geographic Information System (GIS) and statistical data analysis were applied to determine changes in water quality and soil chemistry. These data are the basis for Shishir Sarker's Master's thesis.

本数据集整合自多源数据，涵盖南佛罗里达水务管理区（South Florida Water Management District, SFWMD）DBhydro网络数据库、美国环境保护署区域环境监测与评估（Regional Environmental Monitoring and Assessment, REMAP）、大沼泽地土壤制图（Everglades Soil Mapping, ESM）以及佛罗里达沿海大沼泽地长期生态研究（Florida Coastal Everglades Long Term Ecological Research, FCE-LTER）的相关数据。本数据集针对土壤、地表水、絮状物及植物样品开展整合，测定指标包含总磷、总碳与容重。从DBhydro数据库下载数据时，仅纳入常规采集样品（SAMP）。根据DBhydro的元数据，2004年至2016年间，EPA辖区内的SFWMD监测站点全年采用瞬时采样法每月采集常规样品。所有带标记及经现场质量控制的数值均已剔除，以避免数据重复。为保障质量保证与质量控制（QA/QC），SFWMD将水体总磷的方法检出限设定为2 µg/L。本数据集被用于评估EPA辖区内地表水与土壤中总磷浓度的年代际变化趋势：其中土壤数据的采集时段为2004年至2014年，地表水数据的采集时段为2004年至2016年，以此开展十年尺度的趋势分析。研究采用地理信息系统（GIS）与统计数据分析相结合的方法，解析水质与土壤化学性质的变化特征。本数据集为Shishir Sarker的硕士学位论文提供了核心数据支撑。
