GRANTS: This research was funded by the Natural Environmental Research Council (grant number NE/R009783/1) as part of the SPITFIRE DTP.  
Additional funding was provided by a NERC ‘Grant-in-Kind’ for stable isotope analysis at the Life Sciences Mass Spectrometry Facility (grant number EK312-13/18).

DESCRIPTION OF THE DATA
Biochemical data measured in Atlantic cod, haddock, European hake and European glass eel muscle tissue samples, collected from a range of regions in the Northeast Atlantic Ocean in 2018.
Data includes stable isotope ratios, fatty acid compositions and trace element compositions measured by x-ray fluorescence (XRF).

This dataset contains:
Data for Chapter 2: Tracing the geographic origin of Atlantic cod products using stable isotope analysis
Cod_CNS_data.csv - stable isotope ratios measured in Atlantic cod muscle tissue samples

Data for Chapter 3: Tracing the geographic origin of haddock and European hake products using stable isotope analysis
Haddock_CNS_data.csv - stable isotope ratios measured in haddock muscle tissue samples
Hake_CNS_data.csv - stable isotope ratios measured in hake muscle tissue samples

Data for Chapter 4: Tracing the catch location of critically endangered European glass eels using stable isotope and fatty acid analyses
Eels_CNS_data.csv - stable isotope ratios measured in European glass eel samples
Eels_fatty_acid_data.csv - fatty acid composition measured in European glass eel samples

Data for Chapter 5: Can high-throughput XRF approaches successfully distinguish among cod of different origins: a comparison of two instruments
