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（porewater）样品采集于SRS1b、SRS1c、SRS1d、SRS2、SRS3及TS/Ph-1-5点位，这些点位均位于株高1米的锯草非破坏性生物量样地内。连接泰格管（Tygon tubing）的曝气石被插入土壤表面下10至15厘米处。在湿季每半年开展一次采样，使用莫诺（Monoject）140cc注射器采集至少80毫升孔隙水样品，采集完成后立即将样品置于装满冰的冷藏箱中。实验室对样品的处理流程包括使用折射仪测定盐度，以及通过沃特曼（Whatman）GF/F滤膜对样品进行过滤。对样品中的无机营养盐进行分析，涵盖亚硝酸根（NO₂⁻）、硝酸根（NO₃⁻）、铵根（NH₄⁺）、可溶性活性磷（SRP）以及溶解有机碳（DOC）。溶解态营养盐采用标准快速流动分析仪（Rapid Flow Analyzer, RFA）技术进行测定，溶解有机碳则通过岛津（Shimadzu）总有机碳分析仪完成定量。
