Stable isotope records of sei whale baleens from Chilean Patagonia
The datafile includes nitrogen and carbon isotope analyses of seven baleen plates from six individuals of sei whales (Balaenoptera borealis) from the Chilean-Patagonian fjord area in 0.5 cm resolution. The baleens are from dead carcasses all stranded, except of one, after a mass mortality event in 2...

The datafile includes nitrogen and carbon isotope analyses of seven baleen plates from six individuals of sei whales (Balaenoptera borealis) from the Chilean-Patagonian fjord area in 0.5 cm resolution. The baleens are from dead carcasses all stranded, except of one, after a mass mortality event in 2016 (Häussermann et al. 2017; https://doi.org/10.7717/peerj.3123 ). Carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope variations in baleen plates of sei whales (Balaenoptera borealis) stranded after a mass mortality event in Chilean Patagonia were analyzed to assess potential dietary and migratory patterns. Carbon and nitrogen isotope ratios of seven baleens from six individuals were analyzed. The δ¹³C values ranged from -19.1 to -15.9 ‰ and the d15N values from 8.7 to 15.4 ‰.
