Abstract

This dataset includes sperm whale skin bulk C and N isotopes. A total of 18 skin samples were analyzed. The sperm whale skin tissue came from the California Current System, 1972 to 2005.

Materials and methods for analysis are described in detail in the Ruiz_Cooly et al (2014). Bulk isotope values were analyzed by continuous flow isotope ratio mass spectrometry (IRMS; Thermo Finnigan) and standardized relative to Vienna-Pee Belemnite (V-PDB) for carbon and atmospheric N2 for nitrogen. Results are expressed in part per thousand (‰) and standard notation: dHX= [(Rsample/Rstandard)] x 1000, where H is the mass number of the heavy isotope, X is either C or N, and Rsample and Rstandard are the ratio of 13C/12C or 15N/14N in the sample and standard, respectively.
