Amino acid data set support the manuscript: "Reconstructing the diet, trophic level, and migration pattern of Mysticete whales based on baleen isotopic composition."

Bulk carbon and nitrogen stable isotope values from baleen from stranded and bowcaught whales in the North Sea. Baleen from 5 animals were sampled incrementally and used to examine growth interval, migration pattern, metabolism and trophic position along with bulk isotope data for carbon and nitrogen provided in another data set.
