Water Quality Data (Porewater) from the Taylor Slough, Everglades National Park (FCE), South Florida from September 1999 to December 2006

Porewater samples are collected at SRS1b,SRS2,SRS3, TS/Ph-1-5, 6b within the 1 m^ aboveground sawgrass nondestructive biomass plots. Airstones connected to Tygon tubing are inserted 10-15 cm below the soil surface. Biannually during the wet season, Monoject 140cc syringes are used to collect at least 80 mL of porewater sample and after collection they are immediately placed in an ice filled cooler. The lab processing of these samples include salinity measurements using a refractometer, and filtering the sample through a Whatman GF/F filter. Samples are analyzed for inorganic nutrients such as NO2-,NO3-,NH4+,SRP, and DOC. Dissolved nutrients are measured using standard rapid flow analyzer (RFA) techniques and DOC is quantified on a Shimadzu TOC Analyzer.

孔隙水（porewater）样品采集于SRS1b、SRS2、SRS3、TS/Ph-1-5、6b号样地，上述样地均为1 m^高度范围内的地上锯草无损生物量样地。将连接有Tygon管（Tygon tubing）的曝气石插入土壤表层下10~15 cm处。在湿季内每年开展两次采样，使用Monoject 140cc注射器采集至少80 mL孔隙水样品，采样完成后立即将样品置于装满冰的冷藏箱中。样品的实验室前处理包括使用折光仪（refractometer）测定盐度，以及通过Whatman GF/F滤膜（Whatman GF/F filter）过滤样品。随后对样品中的无机营养盐（包括NO₂⁻、NO₃⁻、NH₄⁺、可溶性活性磷（SRP）以及溶解性有机碳（DOC））进行分析。溶解性营养盐采用标准快速流动分析仪（RFA）技术测定，溶解性有机碳则通过岛津（Shimadzu）TOC分析仪完成定量。
