Water Quality Data (Rainfall-driven autosampler) from the Shark River Slough, Everglades National Park (FCE LTER), Florida, USA, June 2003 - ongoing

Water quality samples are being collected using ISCO autosamplers at all freshwater sites: SRS1a (not active), SRS1c (not active), SRS1d, SRS2, and SRS3. Rain level actuators are used at the sites to trigger water sampling after rain events exceed a given threshold of duration and/or intensity. As currently programmed, when a rain event at a site exceeds the threshold of 2.5 cm per hour, the autosampler at that site collects a 1000mL sample 30 minutes later. The samples are retrieved from the site every 3-4 weeks and analyzed for total phosphorus (TP), total nitrogen (TN), and salinity. Salinity values were not taken consistently from 2000 to mid-2017; those values were replaced by -9999 in the data.

所有淡水站点均使用ISCO自动采样器采集水质样本，涉及站点包括SRS1a（未启用）、SRS1c（未启用）、SRS1d、SRS2和SRS3。各站点配备雨量触发装置，当降雨事件的持续时间和/或强度超过设定阈值时，将启动水样采集。根据当前程序设置，若某站点的降雨强度超过每小时2.5厘米的阈值，该站点的自动采样器会在30分钟后采集1000毫升样本。样本每3-4周从站点取回，分析指标包括总磷（TP）、总氮（TN）和盐度。2000年至2017年中期的盐度数据未持续采集，这些缺失值在数据中以-9999填充。另请参见FCE LTER网站数据目录或EDI数据仓库中的Shark River Slough降水数据包（knb-lter-fce.1092）和Shark River Slough扩展水质数据集（knb-lter-fce.1072）。
