  • Dataset Abstract
    Porewater samples are collected at Florida Coastal Everglades Long Term Ecological Research (FCE LTER) Program Shark River Slough sites SRS1b (not active), SRS1c (not active), SRS1d, SRS2, and SRS3 within the 1 m^2 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 YSI, 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.

    Submission notes:
    Date (Column 3) is only precise to Month and Year (NOT DAY!)
    For SRS1b during the 2004 "wet season", the site was only measured 1 time.
    For SRS3 during the 2001 and 2002 "wet season", the site was only measured 1 time.
    In the 2007 "wet season," no sites were measured.
    No salinity values for SRS1b from Nov-2001 to Nov-2004; for SRS1c from Dec-2005 to Jan-2006; for SRS1d from Nov-2006 to Jan-2017; for SRS2 from Jan 2001 to Jan 2017 and for SRS3 from Jan 2001 to Jan 2017.

    Instrumentation
    Airstone, Tygon tubing (1/16 inner diameter), Whatman GF/F filters (0.7 um), Nalgene Reusable Inline Filter Holder, Monoject 140cc syringes, Computer

    Quality Control
    Field data are written in pencil on waterproof paper and photocopied upon return to the laboratory. They are then entered into the appropriate digital format. These data are reviewed in hard copy and digital format by the lab manager. Laboratory data are written in pencil on waterproof paper, photocopied prior to computer entry and then entered digitally in duplicate and cross-referenced to hard copy notes. Data outliers, determined by comparison to long-term variance in that parameter, are highlighted in resulting spreadsheets for examination by the principal investigator, who may discard the values.
