The data set also contains site location, species composition (determined to the lowest taxonomic level), body size, and elemental concentration information. Data are in spreadsheet format. To examine and compare the trophic structure and food web dynamics between created and natural brackish marshes. Little is known about how river diversions influence the ecological trajectory, food web structure, and function of natural versus created marshes. To address this gap, this project established sites in the West Point a la Hache (WPH) area (Barataria Bay, in Plaquemines Parish, Louisiana), near the WPH siphon which periodically shunts Mississippi River water into the local marshes. Sites were also established in nearby marshes that were restored as part of the Lake Hermitage (LH) Marsh Creation Project, representing an ideal model system to examine how seasonal and spatial shifts in salinity due to river diversions influence species composition and food web structure in both natural and different-aged created marshes. Objectives of the overall project included characterizing species compositions and abundances in multiple trophic levels (microbes to upper trophic level predators) and applying bulk (SIA) and compound-specific stable isotope analysis (CSIA) of amino acids (AA) in producer and consumer tissues to describe and compare the structure and complexity of food webs and reveal aspects of fish residency. Only carbon, nitrogen, and sulfur stable isotope related data are included in this dataset. The data in this accession were funded by the NOAA RESTORE Science Program under award NA17NOS4510091 to Louisiana State University.

Live plant leaves and surface soil organic matter (SOM) were collected along transects and benthic microalgae (BMA) was collected and extracted from surface sediment samples 1 m inland from the marsh edge at each site. Epiphytic algae were opportunistically sampled by hand from ponds and the marsh edge while phytoplankton/particulate organic matter (POM) was collected on GFF filters from triplicate water samples taken approximately 5 m offshore from each site. Samples were dissected, dried, and homogenized as appropriate, with muscle tissue being lipid extracted using 2:1 chloroform:methanol as appropriate, and then analyzed for carbon, nitrogen, and sulfur stable isotope values.
