Title: NOAA RESTORE Science Program: Linking Community and Food-web Approaches to Restoration: Carbon and nitrogen stable isotope values of organisms from created and natural marsh of Lake Hermitage, West Point a la Hache, and Bay Batiste, Louisiana, May 2018 (NCEI Accession 0302883)
Abstract: This dataset contains bulk tissue carbon (delta-13C) and nitrogen (delta-15N) stable isotope values from sediment samples, marsh primary producers, marsh invertebrates, and marsh vertebrates collected at two created and four natural marsh sites in Plaquemines Parish, Louisiana near Lake Hermitage, West Point a la Hache, and Bay Batiste in May 2018. 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.

Supplementary information: Methods: Brackish marsh organisms were collected in May 2018 using minnow traps, fyke nets, otter trawls, dip nets, and by hand from each site. 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 and nitrogen stable isotope values.
