Stable isotope values from coastal Louisiana mangrove and salt marsh communities in May 2016

The salt marshes along the Gulf of Mexico provide a critical habitat for
many species, but their spatial distribution is changing, because black
mangroves (Avicennia germinans) are expanding due to warmer winters.
 This dataset provides bulk carbon, nitrogen and sulfur stable
isotope values of primary producers, soil organic matter, and common
aquatic consumers collected in Spartina alterniflora-dominated (salt
marsh), Avicennia dominated (mangrove), and mixed (transitional) habitats
at two locations in coastal Louisiana. These data can be used to assess
the relative importance of specific basal carbon sources to soil organic
matter and aquatic consumers across habitat types.
