| Abstract: |
As part of the larger NSF WSC funded project, an SF6 tracer study was conducted in November of 2010 by working groups form ENP, FIU and Univ. of Hawaii. This work included the release of the tracer (SF6), which was sampled in a lagrangian approach as the tracer patch moved from the fresh water portion of the system to the mangrove ecotone along the Shark and Harney Rivers. The goal of this study was to measure carbon export through the system. Annie Palya used our new CRDS system to measure the isotopic composition (Delta13C) of the DOM & DIC (analyzed at RSMAS) during this study, as carbon isotopes may help to resolve different sources of carbon. This analytical approach is relatively new, and will be important for understanding the C-dynamics within the FCE. Total organic carbon (TOC), dissolved organic carbon (DOC), and dissolved inorganic carbon (DIC) concentrations from water samples collected within the SF6 tracer plume will be analyzed using an OI Analytical 1030W TOC analyzer. Dissolved organic matter (DOM) will be characterized by means of optical properties analyses as previously described (Chen et al., 2010 and references therein) using UVVis and fluorescence methods including Excitation Emission Matrix (EEM) with parallel factor analysis (PARAFAC). This portion of the study (one sample collected every 2 hrs throughout the tracer experiment) will be conducted as a leverage through the FCE-LTER program. The OI system is coupled to a Picarro CRDS system to measure 13C isotopic composition of the different carbon fractions. Standard water quality procedures will be used during sample collection and storage following the guidelines of the Southeast Research Center Water Quality Laboratory at Florida International University. TOC, DOC, and DIC will be analyzed by using an OI Analytical 1030W TOC analyzer coupled to a Picarro CRDS system to measure 13C isotopic composition of the different fractions of TC from the water sampling at the prescribed collection intervals. Standard water quality procedures will be used during sample collection and storage following the guidelines of the SERC Water Quality Laboratory. We will use the same analyzer to examine C and N ratios of estuary taxa, and thus determine food web structure in the mangrove zone. We will complement the stable isotope analysis with nonlethal stomach content analyses, which provide a high-resolution (i.e., to the species level) snapshot of diet, and predator-prey interactions (Bearhop et al. 2004). |
