资源简介:
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1平方米地上锯齿草非破坏性生物量样地内的SRS1b、SRS1c、SRS1d、SRS2、SRS3及TS/Ph-1-5采样点位。连接有Tygon管(Tygon tubing)的气石被插入土壤表层下10~15厘米处。在湿季每半年开展一次采样,使用Monoject 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放置于装满冰的冷藏箱内。实验室样品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滤膜过滤样品。对样品进行无机营养盐分析,检测指标涵盖亚硝酸盐(NO₂⁻)、硝酸盐(NO₃⁻)、铵根离子(NH₄⁺)、可溶性活性磷(SRP)及溶解有机碳(DOC)。溶解态营养盐采用标准流动分析仪(RFA)技术进行测定,溶解有机碳(DOC)则通过岛津(Shimadzu)TOC分析仪完成定量。
