Stable isotope values for organisms collected in the Rowley River tidal creeks associated with long term fertilization experiments, Rowley, MA.

To assess differences in trophic relationships and enerygy transfer related to long term fertilization of tidal creeks (TIDE Project:  https://thetideproject.org/), organisms including primary producers, invertebrates, and fish were sampled and analyzed for stable isotopes of nitrogen (δ14N) , carbon (δ13C), and sulfur (δ34S).   Collections were made during summers from 2000-2018 from reference and nutrient-enriched branches of 4 tidal creeks.
