Stable Isotope Data for Small Pelagic Fishes across the Northeast U.S. Continental Shelf from 2013-2015

These data represent the carbon and nitrogen stable isotope signatures
of small pelagic fishes across the Northeast U.S. Continental Shelf as
reported by Suca, J.J., et al. (2018) Feeding dynamics of Northwest
Atlantic small pelagic fishes. Progress in Oceanography, 165, 52-62,
https://doi.org/10.1016/j.pocean.2018.04.014. The five species of fish
in this dataset represent a subset of the species collected in bottom
trawls conducted by the NOAA NEFSC Ecosystems Survey Branch from Cape
Hatteras to the Gulf of Maine for years 2013-2015. Sampling occurred
in the Spring and Fall seasons. Sections of dorsal musculature were
analyzed for carbon and nitrogen isotopes using mass spectrometry.
Carbon-to-nitrogen isotopic ratios were reported along with the
isotopic signatures for carbon and nitrogen respectively.
Additionally, a lipid-corrected carbon signature was calculated for
the fish muscle tissue. The dataset was supplemented with geospatial
and temporal information from NOAA Fisheries trawl databases.
