Dataset title: Water Quality Data (Rainfall-driven autosampler) from the Shark River Slough, Everglades National Park (FCE LTER), Florida, USA, June 2003 - ongoing Dataset ID: doi:10.6073/pasta/6f3ec9f848a57cdd20307d5439bb084d Dataset Creator Name: Dr. John Kominoski Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, FL 33199 United States Phone: 305-348-7117 Email: jkominos@fiu.edu Name: Dr. Evelyn Gaiser Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, Florida 33199 USA Phone: 305-348-6145 Email: gaisere@fiu.edu Name: Dr. Daniel Childers Organization: Florida Coastal Everglades LTER Address: Arizona State University PO Box 875502 Tempe, AZ 85287 USA Phone: 480-965-2320 Email: dan.childers@asu.edu Metadata Provider Organization: Florida Coastal Everglades LTER Address: Florida International University 11200 SW 8th Street, OE 148 Miami, FL 33199 USA Phone: 305-348-6054 Email: fcelter@fiu.edu URL: http://fcelter.fiu.edu Dataset Abstract 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.

They were analyzed for salinity, TN, and TP; unfortunately, salinity values were not taken consistently from 2000 to mid 2017; those values were replaced by -9999 in the attached file.

TP is analyzed with a modified Solorzano and Sharp (1980) technique. TN is measured with an Antec TN analyzer, TOC and DOC are quantified on a Shimadzu TOC Analyzer, and salinity is measured with a YSI conductivity meter.
