Measured in the tissues of consumers, nitrogen isotopes (δ15N) are primarily used to estimate trophic position while carbon isotopes (δ13C) describe habitat associations and feeding pathways. Models of both δ15N and δ13C values and their associated variance can be used to estimate likely dietary contributions and niche width and provide inferences about consumer movement and migration. Stable isotope data have added utility when used in combination with other empirical data sets (e.g., stomach content, movement tracking, bioregionalization, contaminant, or fisheries data) and are increasingly relied upon in food web and ecosystem models. While numerous regional studies publish tables of mean δ15N and δ13C values, limited individual records have been made available for wider use. Such a deficiency has impeded full utility of the data which otherwise would facilitate identification of macroscale patterns. The data provided here consist of 4,498 records of individuals of three tuna species, Thunnus alalunga, T. obesus, and T. albacares sampled from all major ocean basins from 2000 to 2015. For each individual tuna we provide a record of the following: species name, sampling date, sampling location, tuna length, muscle bulk and baseline corrected δ15N values, and muscle bulk and, where available, lipid corrected δ13C values. We provide these individual records to support comparative studies and more robust modelling projects seeking to improve understanding of complex marine ecosystem dynamics and their responses to a changing environment.
