Water Quality Data (Porewater) from the Taylor Slough, just outside Everglades National Park (FCE), from August 1998 to October 2006

Porewater samples are collected at SRS1b,SRS1c,SRS1d,SRS2,SRS3, TS/Ph-1-5 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.

孔隙水样品采集于SRS1b、SRS1c、SRS1d、SRS2、SRS3及TS/Ph-1-5点位，上述点位均位于株高1米的无破坏性生物量样地内的锯草群落中。连接有Tygon管的曝气石被插入至土壤表面下10至15厘米处。于湿季每半年开展一次采样，使用Monoject牌140cc注射器采集至少80毫升孔隙水样品，采样完成后立即将样品置于装有冰袋的冷藏箱内。
实验室样品处理环节包括采用折射仪测定盐度，以及通过Whatman GF/F滤膜过滤样品。随后对样品中的亚硝酸盐（NO₂⁻）、硝酸盐（NO₃⁻）、铵盐（NH₄⁺）、可溶性活性磷（Soluble Reactive Phosphorus, SRP）以及溶解性有机碳（Dissolved Organic Carbon, DOC）等无机营养盐进行分析：溶解态营养盐采用标准流动分析仪（Rapid Flow Analyzer, RFA）技术进行测定，溶解性有机碳则通过岛津（Shimadzu）TOC分析仪完成定量。
