Stable carbon and nitrogen isotope values in sequential segments of vibrissae of unrelated northern fur seal pups and adult females at San Miguel Island, California collected during September 2012 (NCEI Accession 0239459)

We analyzed sequential δ13C and δ15N values along single whiskers sampled from unrelated northern fur seal pups and post-parturient females at San Miguel Island, California. The longest dorsal mystacial vibrissa was plucked from five adult females (4-18 years old) and five pups (~3 months old) during September 2012. Standard length (cm), weight (kg), age, and sex were measured/determined for each individual. We divided each vibrissa into 1 mm segments starting at the proximal end and progressing longitudinally toward the distal end. Segments were weighed (µg), packaged, and sent to a laboratory with a mass spectrometer for stable isotope analyses. Resulting data were analyzed to address the purpose of the study.

Purpose Examine the relationship between δ13C and δ15N values in northern fur seal pup vibrissa tissue (sequential segments) with those of unrelated adult females to determine if vibrissae from pups can be used as proxies for those of adult females when examining the foraging ecology/assimilated diet of this species during an overlapping period of time. To estimate vibrissae growth rates and temporally align the vibrissae isotope data. Broadly categorize adult female northern fur seal foraging ecology in the California Current from Fall 2006 to Summer 2012.
