Popis:	Oxygen and carbon isotopes were measured by mass spectrometry from gasified samples drilled out along the nucleus-to-dorsal growth axes of 11 sagittal otoliths of Beryx splendens and one otolith of Coryphaenoides profundicolus. Oxygen and carbon isotope variability was high along the growth axes of the sagittal otoliths of both B. splendens and C. profundicolus, indicating heterogeneous thermal environments over the life of the fish in both species. The correlation between oxygen and carbon isotope disequilibrium was low in B. splendens (r2 = 19.3%) but higher in C. profundicolus (r2 = 68.3%).
