Hello all, If interested, please see below for details about our open-access 'Note' in Marine Mammal Science, which compiles stable isotope data (δ13C and δ15N) for ~90 taxa across ~70 studies. We curated this database with cetaceans and pinnipeds in mind, so hopefully it might help others who are researching these species and/or their common prey from an isotope standpoint.
