Abstract :
[en] This dataset is a compilation of stable isotope ratios of C, N and S in tissues of 2456 sea stars sampled from 1985 to 2017 in the Southern Ocean (Antarctica and Subantarctic Islands). Stable isotope values were measured in the framework of Baptiste Le Bourg's PhD thesis at University of Liège, entitled “Trophic ecology of Southern Ocean sea stars: Influence of environmental drivers on trophic diversity”. Samples were provided by the University of Liège (Belgium), the Université Libre de Bruxelles (Belgium), the National Museum of Natural History (Paris, France) and the Institute of Oceanology of the Polish Academy of Sciences (Sopot, Poland). There could be duplicate records from collections of these institutes published on GBIF and OBIS. This work was supported by BELSPO through the vERSO and RECTO projects (contracts no. BR/132/A1/vERSO and BR/154/A1/RECTO).
